The syncppp drivers in Linux provide a fairly complete
implementation of Cisco HDLC and a minimal implementation of
PPP. The longer term goal is to switch the PPP layer to the
generic PPP interface that is new in Linux 2.3.x. The API should
remain unchanged when this is done, but support will then be
available for IPX, compression and other PPP features

Using hlist_nulls to protect read-mostly linked lists and
objects using SLAB_DESTROY_BY_RCU allocations.
Please read the basics in Documentation/RCU/listRCU.txt
Using special makers (called 'nulls') is a convenient way
to solve following problem :
A typical RCU linked list managing objects which are
allocated with SLAB_DESTROY_BY_RCU kmem_cache can
use following algos :
1) Lookup algo
--------------
rcu_read_lock()
begin:
obj = lockless_lookup(key);
if (obj) {
if (!try_get_ref(obj)) // might fail for free objects
goto begin;
/*
* Because a writer could delete object, and a writer could
* reuse these object before the RCU grace period, we
* must check key after geting the reference on object
*/
if (obj->key != key) { // not the object we expected
put_ref(obj);
goto begin;
}
}
rcu_read_unlock();
Beware that lockless_lookup(key) cannot use traditional hlist_for_each_entry_rcu()
but a version with an additional memory barrier (smp_rmb())
lockless_lookup(key)
{
struct hlist_node *node, *next;
for (pos = rcu_dereference((head)->first);
pos && ({ next = pos->next; smp_rmb(); prefetch(next); 1; }) &&
({ tpos = hlist_entry(pos, typeof(*tpos), member); 1; });
pos = rcu_dereference(next))
if (obj->key == key)
return obj;
return NULL;
And note the traditional hlist_for_each_entry_rcu() misses this smp_rmb() :
struct hlist_node *node;
for (pos = rcu_dereference((head)->first);
pos && ({ prefetch(pos->next); 1; }) &&
({ tpos = hlist_entry(pos, typeof(*tpos), member); 1; });
pos = rcu_dereference(pos->next))
if (obj->key == key)
return obj;
return NULL;
}
Quoting Corey Minyard :
"If the object is moved from one list to another list in-between the
time the hash is calculated and the next field is accessed, and the
object has moved to the end of a new list, the traversal will not
complete properly on the list it should have, since the object will
be on the end of the new list and there's not a way to tell it's on a
new list and restart the list traversal. I think that this can be
solved by pre-fetching the "next" field (with proper barriers) before
checking the key."
2) Insert algo :
----------------
We need to make sure a reader cannot read the new 'obj->obj_next' value
and previous value of 'obj->key'. Or else, an item could be deleted
from a chain, and inserted into another chain. If new chain was empty
before the move, 'next' pointer is NULL, and lockless reader can
not detect it missed following items in original chain.
/*
* Please note that new inserts are done at the head of list,
* not in the middle or end.
*/
obj = kmem_cache_alloc(...);
lock_chain(); // typically a spin_lock()
obj->key = key;
atomic_inc(&obj->refcnt);
/*
* we need to make sure obj->key is updated before obj->next
*/
smp_wmb();
hlist_add_head_rcu(&obj->obj_node, list);
unlock_chain(); // typically a spin_unlock()
3) Remove algo
--------------
Nothing special here, we can use a standard RCU hlist deletion.
But thanks to SLAB_DESTROY_BY_RCU, beware a deleted object can be reused
very very fast (before the end of RCU grace period)
if (put_last_reference_on(obj) {
lock_chain(); // typically a spin_lock()
hlist_del_init_rcu(&obj->obj_node);
unlock_chain(); // typically a spin_unlock()
kmem_cache_free(cachep, obj);
}
--------------------------------------------------------------------------
With hlist_nulls we can avoid extra smp_rmb() in lockless_lookup()
and extra smp_wmb() in insert function.
For example, if we choose to store the slot number as the 'nulls'
end-of-list marker for each slot of the hash table, we can detect
a race (some writer did a delete and/or a move of an object
to another chain) checking the final 'nulls' value if
the lookup met the end of chain. If final 'nulls' value
is not the slot number, then we must restart the lookup at
the begining. If the object was moved to same chain,
then the reader doesnt care : It might eventually
scan the list again without harm.
1) lookup algo
head = &table[slot];
rcu_read_lock();
begin:
hlist_nulls_for_each_entry_rcu(obj, node, head, member) {
if (obj->key == key) {
if (!try_get_ref(obj)) // might fail for free objects
goto begin;
if (obj->key != key) { // not the object we expected
put_ref(obj);
goto begin;
}
goto out;
}
/*
* if the nulls value we got at the end of this lookup is
* not the expected one, we must restart lookup.
* We probably met an item that was moved to another chain.
*/
if (get_nulls_value(node) != slot)
goto begin;
obj = NULL;
out:
rcu_read_unlock();
2) Insert function :
--------------------
/*
* Please note that new inserts are done at the head of list,
* not in the middle or end.
*/
obj = kmem_cache_alloc(cachep);
lock_chain(); // typically a spin_lock()
obj->key = key;
atomic_set(&obj->refcnt, 1);
/*
* insert obj in RCU way (readers might be traversing chain)
*/
hlist_nulls_add_head_rcu(&obj->obj_node, list);
unlock_chain(); // typically a spin_unlock()

CONFIG_RCU_TRACE debugfs Files and Formats
The rcupreempt and rcutree implementations of RCU provide debugfs trace
output that summarizes counters and state. This information is useful for
debugging RCU itself, and can sometimes also help to debug abuses of RCU.
Note that the rcuclassic implementation of RCU does not provide debugfs
trace output.
The following sections describe the debugfs files and formats for
preemptable RCU (rcupreempt) and hierarchical RCU (rcutree).
Preemptable RCU debugfs Files and Formats
This implementation of RCU provides three debugfs files under the
top-level directory RCU: rcu/rcuctrs (which displays the per-CPU
counters used by preemptable RCU) rcu/rcugp (which displays grace-period
counters), and rcu/rcustats (which internal counters for debugging RCU).
The output of "cat rcu/rcuctrs" looks as follows:
CPU last cur F M
0 5 -5 0 0
1 -1 0 0 0
2 0 1 0 0
3 0 1 0 0
4 0 1 0 0
5 0 1 0 0
6 0 2 0 0
7 0 -1 0 0
8 0 1 0 0
ggp = 26226, state = waitzero
The per-CPU fields are as follows:
o "CPU" gives the CPU number. Offline CPUs are not displayed.
o "last" gives the value of the counter that is being decremented
for the current grace period phase. In the example above,
the counters sum to 4, indicating that there are still four
RCU read-side critical sections still running that started
before the last counter flip.
o "cur" gives the value of the counter that is currently being
both incremented (by rcu_read_lock()) and decremented (by
rcu_read_unlock()). In the example above, the counters sum to
1, indicating that there is only one RCU read-side critical section
still running that started after the last counter flip.
o "F" indicates whether RCU is waiting for this CPU to acknowledge
a counter flip. In the above example, RCU is not waiting on any,
which is consistent with the state being "waitzero" rather than
"waitack".
o "M" indicates whether RCU is waiting for this CPU to execute a
memory barrier. In the above example, RCU is not waiting on any,
which is consistent with the state being "waitzero" rather than
"waitmb".
o "ggp" is the global grace-period counter.
o "state" is the RCU state, which can be one of the following:
o "idle": there is no grace period in progress.
o "waitack": RCU just incremented the global grace-period
counter, which has the effect of reversing the roles of
the "last" and "cur" counters above, and is waiting for
all the CPUs to acknowledge the flip. Once the flip has
been acknowledged, CPUs will no longer be incrementing
what are now the "last" counters, so that their sum will
decrease monotonically down to zero.
o "waitzero": RCU is waiting for the sum of the "last" counters
to decrease to zero.
o "waitmb": RCU is waiting for each CPU to execute a memory
barrier, which ensures that instructions from a given CPU's
last RCU read-side critical section cannot be reordered
with instructions following the memory-barrier instruction.
The output of "cat rcu/rcugp" looks as follows:
oldggp=48870 newggp=48873
Note that reading from this file provokes a synchronize_rcu(). The
"oldggp" value is that of "ggp" from rcu/rcuctrs above, taken before
executing the synchronize_rcu(), and the "newggp" value is also the
"ggp" value, but taken after the synchronize_rcu() command returns.
The output of "cat rcu/rcugp" looks as follows:
na=1337955 nl=40 wa=1337915 wl=44 da=1337871 dl=0 dr=1337871 di=1337871
1=50989 e1=6138 i1=49722 ie1=82 g1=49640 a1=315203 ae1=265563 a2=49640
z1=1401244 ze1=1351605 z2=49639 m1=5661253 me1=5611614 m2=49639
These are counters tracking internal preemptable-RCU events, however,
some of them may be useful for debugging algorithms using RCU. In
particular, the "nl", "wl", and "dl" values track the number of RCU
callbacks in various states. The fields are as follows:
o "na" is the total number of RCU callbacks that have been enqueued
since boot.
o "nl" is the number of RCU callbacks waiting for the previous
grace period to end so that they can start waiting on the next
grace period.
o "wa" is the total number of RCU callbacks that have started waiting
for a grace period since boot. "na" should be roughly equal to
"nl" plus "wa".
o "wl" is the number of RCU callbacks currently waiting for their
grace period to end.
o "da" is the total number of RCU callbacks whose grace periods
have completed since boot. "wa" should be roughly equal to
"wl" plus "da".
o "dr" is the total number of RCU callbacks that have been removed
from the list of callbacks ready to invoke. "dr" should be roughly
equal to "da".
o "di" is the total number of RCU callbacks that have been invoked
since boot. "di" should be roughly equal to "da", though some
early versions of preemptable RCU had a bug so that only the
last CPU's count of invocations was displayed, rather than the
sum of all CPU's counts.
o "1" is the number of calls to rcu_try_flip(). This should be
roughly equal to the sum of "e1", "i1", "a1", "z1", and "m1"
described below. In other words, the number of times that
the state machine is visited should be equal to the sum of the
number of times that each state is visited plus the number of
times that the state-machine lock acquisition failed.
o "e1" is the number of times that rcu_try_flip() was unable to
acquire the fliplock.
o "i1" is the number of calls to rcu_try_flip_idle().
o "ie1" is the number of times rcu_try_flip_idle() exited early
due to the calling CPU having no work for RCU.
o "g1" is the number of times that rcu_try_flip_idle() decided
to start a new grace period. "i1" should be roughly equal to
"ie1" plus "g1".
o "a1" is the number of calls to rcu_try_flip_waitack().
o "ae1" is the number of times that rcu_try_flip_waitack() found
that at least one CPU had not yet acknowledge the new grace period
(AKA "counter flip").
o "a2" is the number of time rcu_try_flip_waitack() found that
all CPUs had acknowledged. "a1" should be roughly equal to
"ae1" plus "a2". (This particular output was collected on
a 128-CPU machine, hence the smaller-than-usual fraction of
calls to rcu_try_flip_waitack() finding all CPUs having already
acknowledged.)
o "z1" is the number of calls to rcu_try_flip_waitzero().
o "ze1" is the number of times that rcu_try_flip_waitzero() found
that not all of the old RCU read-side critical sections had
completed.
o "z2" is the number of times that rcu_try_flip_waitzero() finds
the sum of the counters equal to zero, in other words, that
all of the old RCU read-side critical sections had completed.
The value of "z1" should be roughly equal to "ze1" plus
"z2".
o "m1" is the number of calls to rcu_try_flip_waitmb().
o "me1" is the number of times that rcu_try_flip_waitmb() finds
that at least one CPU has not yet executed a memory barrier.
o "m2" is the number of times that rcu_try_flip_waitmb() finds that
all CPUs have executed a memory barrier.
Hierarchical RCU debugfs Files and Formats
This implementation of RCU provides three debugfs files under the
top-level directory RCU: rcu/rcudata (which displays fields in struct
rcu_data), rcu/rcugp (which displays grace-period counters), and
rcu/rcuhier (which displays the struct rcu_node hierarchy).
The output of "cat rcu/rcudata" looks as follows:
rcu:

The first section lists the rcu_data structures for rcu, the second for
rcu_bh. Each section has one line per CPU, or eight for this 8-CPU system.
The fields are as follows:
o The number at the beginning of each line is the CPU number.
CPUs numbers followed by an exclamation mark are offline,
but have been online at least once since boot. There will be
no output for CPUs that have never been online, which can be
a good thing in the surprisingly common case where NR_CPUS is
substantially larger than the number of actual CPUs.
o "c" is the count of grace periods that this CPU believes have
completed. CPUs in dynticks idle mode may lag quite a ways
behind, for example, CPU 4 under "rcu" above, which has slept
through the past 25 RCU grace periods. It is not unusual to
see CPUs lagging by thousands of grace periods.
o "g" is the count of grace periods that this CPU believes have
started. Again, CPUs in dynticks idle mode may lag behind.
If the "c" and "g" values are equal, this CPU has already
reported a quiescent state for the last RCU grace period that
it is aware of, otherwise, the CPU believes that it owes RCU a
quiescent state.
o "pq" indicates that this CPU has passed through a quiescent state
for the current grace period. It is possible for "pq" to be
"1" and "c" different than "g", which indicates that although
the CPU has passed through a quiescent state, either (1) this
CPU has not yet reported that fact, (2) some other CPU has not
yet reported for this grace period, or (3) both.
o "pqc" indicates which grace period the last-observed quiescent
state for this CPU corresponds to. This is important for handling
the race between CPU 0 reporting an extended dynticks-idle
quiescent state for CPU 1 and CPU 1 suddenly waking up and
reporting its own quiescent state. If CPU 1 was the last CPU
for the current grace period, then the CPU that loses this race
will attempt to incorrectly mark CPU 1 as having checked in for
the next grace period!
o "qp" indicates that RCU still expects a quiescent state from
this CPU.
o "rpfq" is the number of rcu_pending() calls on this CPU required
to induce this CPU to invoke force_quiescent_state().
o "rp" is low-order four hex digits of the count of how many times
rcu_pending() has been invoked on this CPU.
o "dt" is the current value of the dyntick counter that is incremented
when entering or leaving dynticks idle state, either by the
scheduler or by irq. The number after the "/" is the interrupt
nesting depth when in dyntick-idle state, or one greater than
the interrupt-nesting depth otherwise.
This field is displayed only for CONFIG_NO_HZ kernels.
o "dn" is the current value of the dyntick counter that is incremented
when entering or leaving dynticks idle state via NMI. If both
the "dt" and "dn" values are even, then this CPU is in dynticks
idle mode and may be ignored by RCU. If either of these two
counters is odd, then RCU must be alert to the possibility of
an RCU read-side critical section running on this CPU.
This field is displayed only for CONFIG_NO_HZ kernels.
o "df" is the number of times that some other CPU has forced a
quiescent state on behalf of this CPU due to this CPU being in
dynticks-idle state.
This field is displayed only for CONFIG_NO_HZ kernels.
o "of" is the number of times that some other CPU has forced a
quiescent state on behalf of this CPU due to this CPU being
offline. In a perfect world, this might neve happen, but it
turns out that offlining and onlining a CPU can take several grace
periods, and so there is likely to be an extended period of time
when RCU believes that the CPU is online when it really is not.
Please note that erring in the other direction (RCU believing a
CPU is offline when it is really alive and kicking) is a fatal
error, so it makes sense to err conservatively.
o "ri" is the number of times that RCU has seen fit to send a
reschedule IPI to this CPU in order to get it to report a
quiescent state.
o "ql" is the number of RCU callbacks currently residing on
this CPU. This is the total number of callbacks, regardless
of what state they are in (new, waiting for grace period to
start, waiting for grace period to end, ready to invoke).
o "b" is the batch limit for this CPU. If more than this number
of RCU callbacks is ready to invoke, then the remainder will
be deferred.
The output of "cat rcu/rcugp" looks as follows:
rcu: completed=33062 gpnum=33063
rcu_bh: completed=464 gpnum=464
Again, this output is for both "rcu" and "rcu_bh". The fields are
taken from the rcu_state structure, and are as follows:
o "completed" is the number of grace periods that have completed.
It is comparable to the "c" field from rcu/rcudata in that a
CPU whose "c" field matches the value of "completed" is aware
that the corresponding RCU grace period has completed.
o "gpnum" is the number of grace periods that have started. It is
comparable to the "g" field from rcu/rcudata in that a CPU
whose "g" field matches the value of "gpnum" is aware that the
corresponding RCU grace period has started.
If these two fields are equal (as they are for "rcu_bh" above),
then there is no grace period in progress, in other words, RCU
is idle. On the other hand, if the two fields differ (as they
do for "rcu" above), then an RCU grace period is in progress.
The output of "cat rcu/rcuhier" looks as follows, with very long lines:

This is once again split into "rcu" and "rcu_bh" portions. The fields are
as follows:
o "c" is exactly the same as "completed" under rcu/rcugp.
o "g" is exactly the same as "gpnum" under rcu/rcugp.
o "s" is the "signaled" state that drives force_quiescent_state()'s
state machine.
o "jfq" is the number of jiffies remaining for this grace period
before force_quiescent_state() is invoked to help push things
along. Note that CPUs in dyntick-idle mode thoughout the grace
period will not report on their own, but rather must be check by
some other CPU via force_quiescent_state().
o "j" is the low-order four hex digits of the jiffies counter.
Yes, Paul did run into a number of problems that turned out to
be due to the jiffies counter no longer counting. Why do you ask?
o "nfqs" is the number of calls to force_quiescent_state() since
boot.
o "nfqsng" is the number of useless calls to force_quiescent_state(),
where there wasn't actually a grace period active. This can
happen due to races. The number in parentheses is the difference
between "nfqs" and "nfqsng", or the number of times that
force_quiescent_state() actually did some real work.
o "fqlh" is the number of calls to force_quiescent_state() that
exited immediately (without even being counted in nfqs above)
due to contention on ->fqslock.
o Each element of the form "1/1 0:127 ^0" represents one struct
rcu_node. Each line represents one level of the hierarchy, from
root to leaves. It is best to think of the rcu_data structures
as forming yet another level after the leaves. Note that there
might be either one, two, or three levels of rcu_node structures,
depending on the relationship between CONFIG_RCU_FANOUT and
CONFIG_NR_CPUS.
o The numbers separated by the "/" are the qsmask followed
by the qsmaskinit. The qsmask will have one bit
set for each entity in the next lower level that
has not yet checked in for the current grace period.
The qsmaskinit will have one bit for each entity that is
currently expected to check in during each grace period.
The value of qsmaskinit is assigned to that of qsmask
at the beginning of each grace period.
For example, for "rcu", the qsmask of the first entry
of the lowest level is 0x14, meaning that we are still
waiting for CPUs 2 and 4 to check in for the current
grace period.
o The numbers separated by the ":" are the range of CPUs
served by this struct rcu_node. This can be helpful
in working out how the hierarchy is wired together.
For example, the first entry at the lowest level shows
"0:5", indicating that it covers CPUs 0 through 5.
o The number after the "^" indicates the bit in the
next higher level rcu_node structure that this
rcu_node structure corresponds to.
For example, the first entry at the lowest level shows
"^0", indicating that it corresponds to bit zero in
the first entry at the middle level.

MFP Configuration for PXA2xx/PXA3xx Processors
Eric Miao <eric.miao@marvell.com>
MFP stands for Multi-Function Pin, which is the pin-mux logic on PXA3xx and
later PXA series processors. This document describes the existing MFP API,
and how board/platform driver authors could make use of it.
Basic Concept
===============
Unlike the GPIO alternate function settings on PXA25x and PXA27x, a new MFP
mechanism is introduced from PXA3xx to completely move the pin-mux functions
out of the GPIO controller. In addition to pin-mux configurations, the MFP
also controls the low power state, driving strength, pull-up/down and event
detection of each pin. Below is a diagram of internal connections between
the MFP logic and the remaining SoC peripherals:
+--------+
| |--(GPIO19)--+
| GPIO | |
| |--(GPIO...) |
+--------+ |
| +---------+
+--------+ +------>| |
| PWM2 |--(PWM_OUT)-------->| MFP |
+--------+ +------>| |-------> to external PAD
| +---->| |
+--------+ | | +-->| |
| SSP2 |---(TXD)----+ | | +---------+
+--------+ | |
| |
+--------+ | |
| Keypad |--(MKOUT4)----+ |
+--------+ |
|
+--------+ |
| UART2 |---(TXD)--------+
+--------+
NOTE: the external pad is named as MFP_PIN_GPIO19, it doesn't necessarily
mean it's dedicated for GPIO19, only as a hint that internally this pin
can be routed from GPIO19 of the GPIO controller.
To better understand the change from PXA25x/PXA27x GPIO alternate function
to this new MFP mechanism, here are several key points:
1. GPIO controller on PXA3xx is now a dedicated controller, same as other
internal controllers like PWM, SSP and UART, with 128 internal signals
which can be routed to external through one or more MFPs (e.g. GPIO<0>
can be routed through either MFP_PIN_GPIO0 as well as MFP_PIN_GPIO0_2,
see arch/arm/mach-pxa/mach/include/mfp-pxa300.h)
2. Alternate function configuration is removed from this GPIO controller,
the remaining functions are pure GPIO-specific, i.e.
- GPIO signal level control
- GPIO direction control
- GPIO level change detection
3. Low power state for each pin is now controlled by MFP, this means the
PGSRx registers on PXA2xx are now useless on PXA3xx
4. Wakeup detection is now controlled by MFP, PWER does not control the
wakeup from GPIO(s) any more, depending on the sleeping state, ADxER
(as defined in pxa3xx-regs.h) controls the wakeup from MFP
NOTE: with such a clear separation of MFP and GPIO, by GPIO<xx> we normally
mean it is a GPIO signal, and by MFP<xxx> or pin xxx, we mean a physical
pad (or ball).
MFP API Usage
===============
For board code writers, here are some guidelines:
1. include ONE of the following header files in your <board>.c:
- #include <mach/mfp-pxa25x.h>
- #include <mach/mfp-pxa27x.h>
- #include <mach/mfp-pxa300.h>
- #include <mach/mfp-pxa320.h>
- #include <mach/mfp-pxa930.h>
NOTE: only one file in your <board>.c, depending on the processors used,
because pin configuration definitions may conflict in these file (i.e.
same name, different meaning and settings on different processors). E.g.
for zylonite platform, which support both PXA300/PXA310 and PXA320, two
separate files are introduced: zylonite_pxa300.c and zylonite_pxa320.c
(in addition to handle MFP configuration differences, they also handle
the other differences between the two combinations).
NOTE: PXA300 and PXA310 are almost identical in pin configurations (with
PXA310 supporting some additional ones), thus the difference is actually
covered in a single mfp-pxa300.h.
2. prepare an array for the initial pin configurations, e.g.:
static unsigned long mainstone_pin_config[] __initdata = {
/* Chip Select */
GPIO15_nCS_1,
/* LCD - 16bpp Active TFT */
GPIOxx_TFT_LCD_16BPP,
GPIO16_PWM0_OUT, /* Backlight */
/* MMC */
GPIO32_MMC_CLK,
GPIO112_MMC_CMD,
GPIO92_MMC_DAT_0,
GPIO109_MMC_DAT_1,
GPIO110_MMC_DAT_2,
GPIO111_MMC_DAT_3,
...
/* GPIO */
GPIO1_GPIO | WAKEUP_ON_EDGE_BOTH,
};
a) once the pin configurations are passed to pxa{2xx,3xx}_mfp_config(),
and written to the actual registers, they are useless and may discard,
adding '__initdata' will help save some additional bytes here.
b) when there is only one possible pin configurations for a component,
some simplified definitions can be used, e.g. GPIOxx_TFT_LCD_16BPP on
PXA25x and PXA27x processors
c) if by board design, a pin can be configured to wake up the system
from low power state, it can be 'OR'ed with any of:
WAKEUP_ON_EDGE_BOTH
WAKEUP_ON_EDGE_RISE
WAKEUP_ON_EDGE_FALL
WAKEUP_ON_LEVEL_HIGH - specifically for enabling of keypad GPIOs,
to indicate that this pin has the capability of wake-up the system,
and on which edge(s). This, however, doesn't necessarily mean the
pin _will_ wakeup the system, it will only when set_irq_wake() is
invoked with the corresponding GPIO IRQ (GPIO_IRQ(xx) or gpio_to_irq())
and eventually calls gpio_set_wake() for the actual register setting.
d) although PXA3xx MFP supports edge detection on each pin, the
internal logic will only wakeup the system when those specific bits
in ADxER registers are set, which can be well mapped to the
corresponding peripheral, thus set_irq_wake() can be called with
the peripheral IRQ to enable the wakeup.
MFP on PXA3xx
===============
Every external I/O pad on PXA3xx (excluding those for special purpose) has
one MFP logic associated, and is controlled by one MFP register (MFPR).
The MFPR has the following bit definitions (for PXA300/PXA310/PXA320):
31 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
+-------------------------+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
| RESERVED |PS|PU|PD| DRIVE |SS|SD|SO|EC|EF|ER|--| AF_SEL |
+-------------------------+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
Bit 3: RESERVED
Bit 4: EDGE_RISE_EN - enable detection of rising edge on this pin
Bit 5: EDGE_FALL_EN - enable detection of falling edge on this pin
Bit 6: EDGE_CLEAR - disable edge detection on this pin
Bit 7: SLEEP_OE_N - enable outputs during low power modes
Bit 8: SLEEP_DATA - output data on the pin during low power modes
Bit 9: SLEEP_SEL - selection control for low power modes signals
Bit 13: PULLDOWN_EN - enable the internal pull-down resistor on this pin
Bit 14: PULLUP_EN - enable the internal pull-up resistor on this pin
Bit 15: PULL_SEL - pull state controlled by selected alternate function
(0) or by PULL{UP,DOWN}_EN bits (1)
Bit 0 - 2: AF_SEL - alternate function selection, 8 possibilities, from 0-7
Bit 10-12: DRIVE - drive strength and slew rate
0b000 - fast 1mA
0b001 - fast 2mA
0b002 - fast 3mA
0b003 - fast 4mA
0b004 - slow 6mA
0b005 - fast 6mA
0b006 - slow 10mA
0b007 - fast 10mA
MFP Design for PXA2xx/PXA3xx
==============================
Due to the difference of pin-mux handling between PXA2xx and PXA3xx, a unified
MFP API is introduced to cover both series of processors.
The basic idea of this design is to introduce definitions for all possible pin
configurations, these definitions are processor and platform independent, and
the actual API invoked to convert these definitions into register settings and
make them effective there-after.

Pin Configuration
-----------------
The following comments are copied from mfp.h (see the actual source code
for most updated info)
/*
* a possible MFP configuration is represented by a 32-bit integer
*
* bit 0.. 9 - MFP Pin Number (1024 Pins Maximum)
* bit 10..12 - Alternate Function Selection
* bit 13..15 - Drive Strength
* bit 16..18 - Low Power Mode State
* bit 19..20 - Low Power Mode Edge Detection
* bit 21..22 - Run Mode Pull State
*
* to facilitate the definition, the following macros are provided
*
* MFP_CFG_DEFAULT - default MFP configuration value, with
* alternate function = 0,
* drive strength = fast 3mA (MFP_DS03X)
* low power mode = default
* edge detection = none
*
* MFP_CFG - default MFPR value with alternate function
* MFP_CFG_DRV - default MFPR value with alternate function and
* pin drive strength
* MFP_CFG_LPM - default MFPR value with alternate function and
* low power mode
* MFP_CFG_X - default MFPR value with alternate function,
* pin drive strength and low power mode
*/
Examples of pin configurations are:
#define GPIO94_SSP3_RXD MFP_CFG_X(GPIO94, AF1, DS08X, FLOAT)
which reads GPIO94 can be configured as SSP3_RXD, with alternate function
selection of 1, driving strength of 0b101, and a float state in low power
modes.
NOTE: this is the default setting of this pin being configured as SSP3_RXD
which can be modified a bit in board code, though it is not recommended to
do so, simply because this default setting is usually carefully encoded,
and is supposed to work in most cases.
Register Settings
-----------------
Register settings on PXA3xx for a pin configuration is actually very
straight-forward, most bits can be converted directly into MFPR value
in a easier way. Two sets of MFPR values are calculated: the run-time
ones and the low power mode ones, to allow different settings.
The conversion from a generic pin configuration to the actual register
settings on PXA2xx is a bit complicated: many registers are involved,
including GAFRx, GPDRx, PGSRx, PWER, PKWR, PFER and PRER. Please see
mfp-pxa2xx.c for how the conversion is made.

CPU Accounting Controller
-------------------------
The CPU accounting controller is used to group tasks using cgroups and
account the CPU usage of these groups of tasks.
The CPU accounting controller supports multi-hierarchy groups. An accounting
group accumulates the CPU usage of all of its child groups and the tasks
directly present in its group.
Accounting groups can be created by first mounting the cgroup filesystem.
# mkdir /cgroups
# mount -t cgroup -ocpuacct none /cgroups
With the above step, the initial or the parent accounting group
becomes visible at /cgroups. At bootup, this group includes all the
tasks in the system. /cgroups/tasks lists the tasks in this cgroup.
/cgroups/cpuacct.usage gives the CPU time (in nanoseconds) obtained by
this group which is essentially the CPU time obtained by all the tasks
in the system.
New accounting groups can be created under the parent group /cgroups.
# cd /cgroups
# mkdir g1
# echo $$ > g1
The above steps create a new group g1 and move the current shell
process (bash) into it. CPU time consumed by this bash and its children
can be obtained from g1/cpuacct.usage and the same is accumulated in
/cgroups/cpuacct.usage also.

CREDENTIALS IN LINUX
====================

- Accessing another task's credentials.

- Managing credentials.

========
OVERVIEW
========
There are several parts to the security check performed by Linux when one
object acts upon another:
(1) Objects.
Objects are things in the system that may be acted upon directly by
userspace programs. Linux has a variety of actionable objects, including:
- Tasks
- Files/inodes
- Sockets
- Message queues
- Shared memory segments
- Semaphores
- Keys
As a part of the description of all these objects there is a set of
credentials. What's in the set depends on the type of object.
(2) Object ownership.
Amongst the credentials of most objects, there will be a subset that
indicates the ownership of that object. This is used for resource
accounting and limitation (disk quotas and task rlimits for example).
In a standard UNIX filesystem, for instance, this will be defined by the
UID marked on the inode.
(3) The objective context.
Also amongst the credentials of those objects, there will be a subset that
indicates the 'objective context' of that object. This may or may not be
the same set as in (2) - in standard UNIX files, for instance, this is the
defined by the UID and the GID marked on the inode.
The objective context is used as part of the security calculation that is
carried out when an object is acted upon.
(4) Subjects.
A subject is an object that is acting upon another object.
Most of the objects in the system are inactive: they don't act on other
objects within the system. Processes/tasks are the obvious exception:
they do stuff; they access and manipulate things.
Objects other than tasks may under some circumstances also be subjects.
For instance an open file may send SIGIO to a task using the UID and EUID
given to it by a task that called fcntl(F_SETOWN) upon it. In this case,
the file struct will have a subjective context too.
(5) The subjective context.
A subject has an additional interpretation of its credentials. A subset
of its credentials forms the 'subjective context'. The subjective context
is used as part of the security calculation that is carried out when a
subject acts.
A Linux task, for example, has the FSUID, FSGID and the supplementary
group list for when it is acting upon a file - which are quite separate
from the real UID and GID that normally form the objective context of the
task.
(6) Actions.
Linux has a number of actions available that a subject may perform upon an
object. The set of actions available depends on the nature of the subject
and the object.
Actions include reading, writing, creating and deleting files; forking or
signalling and tracing tasks.
(7) Rules, access control lists and security calculations.
When a subject acts upon an object, a security calculation is made. This
involves taking the subjective context, the objective context and the
action, and searching one or more sets of rules to see whether the subject
is granted or denied permission to act in the desired manner on the
object, given those contexts.
There are two main sources of rules:
(a) Discretionary access control (DAC):
Sometimes the object will include sets of rules as part of its
description. This is an 'Access Control List' or 'ACL'. A Linux
file may supply more than one ACL.
A traditional UNIX file, for example, includes a permissions mask that
is an abbreviated ACL with three fixed classes of subject ('user',
'group' and 'other'), each of which may be granted certain privileges
('read', 'write' and 'execute' - whatever those map to for the object
in question). UNIX file permissions do not allow the arbitrary
specification of subjects, however, and so are of limited use.
A Linux file might also sport a POSIX ACL. This is a list of rules
that grants various permissions to arbitrary subjects.
(b) Mandatory access control (MAC):
The system as a whole may have one or more sets of rules that get
applied to all subjects and objects, regardless of their source.
SELinux and Smack are examples of this.
In the case of SELinux and Smack, each object is given a label as part
of its credentials. When an action is requested, they take the
subject label, the object label and the action and look for a rule
that says that this action is either granted or denied.
====================
TYPES OF CREDENTIALS
====================
The Linux kernel supports the following types of credentials:
(1) Traditional UNIX credentials.
Real User ID
Real Group ID
The UID and GID are carried by most, if not all, Linux objects, even if in
some cases it has to be invented (FAT or CIFS files for example, which are
derived from Windows). These (mostly) define the objective context of
that object, with tasks being slightly different in some cases.
Effective, Saved and FS User ID
Effective, Saved and FS Group ID
Supplementary groups
These are additional credentials used by tasks only. Usually, an
EUID/EGID/GROUPS will be used as the subjective context, and real UID/GID
will be used as the objective. For tasks, it should be noted that this is
not always true.
(2) Capabilities.
Set of permitted capabilities
Set of inheritable capabilities
Set of effective capabilities
Capability bounding set
These are only carried by tasks. They indicate superior capabilities
granted piecemeal to a task that an ordinary task wouldn't otherwise have.
These are manipulated implicitly by changes to the traditional UNIX
credentials, but can also be manipulated directly by the capset() system
call.
The permitted capabilities are those caps that the process might grant
itself to its effective or permitted sets through capset(). This
inheritable set might also be so constrained.
The effective capabilities are the ones that a task is actually allowed to
make use of itself.
The inheritable capabilities are the ones that may get passed across
execve().
The bounding set limits the capabilities that may be inherited across
execve(), especially when a binary is executed that will execute as UID 0.
(3) Secure management flags (securebits).
These are only carried by tasks. These govern the way the above
credentials are manipulated and inherited over certain operations such as
execve(). They aren't used directly as objective or subjective
credentials.
(4) Keys and keyrings.
These are only carried by tasks. They carry and cache security tokens
that don't fit into the other standard UNIX credentials. They are for
making such things as network filesystem keys available to the file
accesses performed by processes, without the necessity of ordinary
programs having to know about security details involved.
Keyrings are a special type of key. They carry sets of other keys and can
be searched for the desired key. Each process may subscribe to a number
of keyrings:
Per-thread keying
Per-process keyring
Per-session keyring
When a process accesses a key, if not already present, it will normally be
cached on one of these keyrings for future accesses to find.
For more information on using keys, see Documentation/keys.txt.
(5) LSM
The Linux Security Module allows extra controls to be placed over the
operations that a task may do. Currently Linux supports two main
alternate LSM options: SELinux and Smack.
Both work by labelling the objects in a system and then applying sets of
rules (policies) that say what operations a task with one label may do to
an object with another label.
(6) AF_KEY
This is a socket-based approach to credential management for networking
stacks [RFC 2367]. It isn't discussed by this document as it doesn't
interact directly with task and file credentials; rather it keeps system
level credentials.
When a file is opened, part of the opening task's subjective context is
recorded in the file struct created. This allows operations using that file
struct to use those credentials instead of the subjective context of the task
that issued the operation. An example of this would be a file opened on a
network filesystem where the credentials of the opened file should be presented
to the server, regardless of who is actually doing a read or a write upon it.
=============
FILE MARKINGS
=============
Files on disk or obtained over the network may have annotations that form the
objective security context of that file. Depending on the type of filesystem,
this may include one or more of the following:
(*) UNIX UID, GID, mode;
(*) Windows user ID;
(*) Access control list;
(*) LSM security label;
(*) UNIX exec privilege escalation bits (SUID/SGID);
(*) File capabilities exec privilege escalation bits.
These are compared to the task's subjective security context, and certain
operations allowed or disallowed as a result. In the case of execve(), the

================
TASK CREDENTIALS
================
In Linux, all of a task's credentials are held in (uid, gid) or through
(groups, keys, LSM security) a refcounted structure of type 'struct cred'.
Each task points to its credentials by a pointer called 'cred' in its
task_struct.
Once a set of credentials has been prepared and committed, it may not be
changed, barring the following exceptions:
(1) its reference count may be changed;
(2) the reference count on the group_info struct it points to may be changed;
(3) the reference count on the security data it points to may be changed;
(4) the reference count on any keyrings it points to may be changed;
(5) any keyrings it points to may be revoked, expired or have their security
attributes changed; and
(6) the contents of any keyrings to which it points may be changed (the whole
point of keyrings being a shared set of credentials, modifiable by anyone
with appropriate access).
To alter anything in the cred struct, the copy-and-replace principle must be
adhered to. First take a copy, then alter the copy and then use RCU to change
the task pointer to make it point to the new copy. There are wrappers to aid
with this (see below).
A task may only alter its _own_ credentials; it is no longer permitted for a
task to alter another's credentials. This means the capset() system call is no
longer permitted to take any PID other than the one of the current process.
Also keyctl_instantiate() and keyctl_negate() functions no longer permit
attachment to process-specific keyrings in the requesting process as the
instantiating process may need to create them.
IMMUTABLE CREDENTIALS
---------------------
Once a set of credentials has been made public (by calling commit_creds() for
example), it must be considered immutable, barring two exceptions:
(1) The reference count may be altered.
(2) Whilst the keyring subscriptions of a set of credentials may not be
changed, the keyrings subscribed to may have their contents altered.
To catch accidental credential alteration at compile time, struct task_struct
has _const_ pointers to its credential sets, as does struct file. Furthermore,
certain functions such as get_cred() and put_cred() operate on const pointers,
thus rendering casts unnecessary, but require to temporarily ditch the const
qualification to be able to alter the reference count.
ACCESSING TASK CREDENTIALS
--------------------------
A task being able to alter only its own credentials permits the current process
to read or replace its own credentials without the need for any form of locking
- which simplifies things greatly. It can just call:
const struct cred *current_cred()
to get a pointer to its credentials structure, and it doesn't have to release
it afterwards.
There are convenience wrappers for retrieving specific aspects of a task's
credentials (the value is simply returned in each case):
uid_t current_uid(void) Current's real UID
gid_t current_gid(void) Current's real GID
uid_t current_euid(void) Current's effective UID
gid_t current_egid(void) Current's effective GID
uid_t current_fsuid(void) Current's file access UID
gid_t current_fsgid(void) Current's file access GID
kernel_cap_t current_cap(void) Current's effective capabilities
void *current_security(void) Current's LSM security pointer
struct user_struct *current_user(void) Current's user account
There are also convenience wrappers for retrieving specific associated pairs of
a task's credentials:
void current_uid_gid(uid_t *, gid_t *);
void current_euid_egid(uid_t *, gid_t *);
void current_fsuid_fsgid(uid_t *, gid_t *);
which return these pairs of values through their arguments after retrieving
them from the current task's credentials.
In addition, there is a function for obtaining a reference on the current
process's current set of credentials:
const struct cred *get_current_cred(void);
and functions for getting references to one of the credentials that don't
actually live in struct cred:
struct user_struct *get_current_user(void);
struct group_info *get_current_groups(void);
which get references to the current process's user accounting structure and
supplementary groups list respectively.
Once a reference has been obtained, it must be released with put_cred(),
free_uid() or put_group_info() as appropriate.
ACCESSING ANOTHER TASK'S CREDENTIALS
------------------------------------
Whilst a task may access its own credentials without the need for locking, the
same is not true of a task wanting to access another task's credentials. It
must use the RCU read lock and rcu_dereference().
The rcu_dereference() is wrapped by:
const struct cred *__task_cred(struct task_struct *task);
This should be used inside the RCU read lock, as in the following example:
void foo(struct task_struct *t, struct foo_data *f)
{
const struct cred *tcred;
...
rcu_read_lock();
tcred = __task_cred(t);
f->uid = tcred->uid;
f->gid = tcred->gid;
f->groups = get_group_info(tcred->groups);
rcu_read_unlock();
...
}
A function need not get RCU read lock to use __task_cred() if it is holding a
spinlock at the time as this implicitly holds the RCU read lock.
Should it be necessary to hold another task's credentials for a long period of
time, and possibly to sleep whilst doing so, then the caller should get a
reference on them using:
const struct cred *get_task_cred(struct task_struct *task);
This does all the RCU magic inside of it. The caller must call put_cred() on
the credentials so obtained when they're finished with.
There are a couple of convenience functions to access bits of another task's
credentials, hiding the RCU magic from the caller:
uid_t task_uid(task) Task's real UID
uid_t task_euid(task) Task's effective UID
If the caller is holding a spinlock or the RCU read lock at the time anyway,
then:
__task_cred(task)->uid
__task_cred(task)->euid
should be used instead. Similarly, if multiple aspects of a task's credentials
need to be accessed, RCU read lock or a spinlock should be used, __task_cred()
called, the result stored in a temporary pointer and then the credential
aspects called from that before dropping the lock. This prevents the
potentially expensive RCU magic from being invoked multiple times.
Should some other single aspect of another task's credentials need to be
accessed, then this can be used:
task_cred_xxx(task, member)
where 'member' is a non-pointer member of the cred struct. For instance:
uid_t task_cred_xxx(task, suid);
will retrieve 'struct cred::suid' from the task, doing the appropriate RCU
magic. This may not be used for pointer members as what they point to may
disappear the moment the RCU read lock is dropped.
ALTERING CREDENTIALS
--------------------
As previously mentioned, a task may only alter its own credentials, and may not
alter those of another task. This means that it doesn't need to use any
locking to alter its own credentials.
To alter the current process's credentials, a function should first prepare a
new set of credentials by calling:
struct cred *prepare_creds(void);
this locks current->cred_replace_mutex and then allocates and constructs a
duplicate of the current process's credentials, returning with the mutex still
held if successful. It returns NULL if not successful (out of memory).
The mutex prevents ptrace() from altering the ptrace state of a process whilst
security checks on credentials construction and changing is taking place as
the ptrace state may alter the outcome, particularly in the case of execve().
The new credentials set should be altered appropriately, and any security
checks and hooks done. Both the current and the proposed sets of credentials
are available for this purpose as current_cred() will return the current set
still at this point.
When the credential set is ready, it should be committed to the current process
by calling:
int commit_creds(struct cred *new);
This will alter various aspects of the credentials and the process, giving the
LSM a chance to do likewise, then it will use rcu_assign_pointer() to actually
commit the new credentials to current->cred, it will release
current->cred_replace_mutex to allow ptrace() to take place, and it will notify
the scheduler and others of the changes.
This function is guaranteed to return 0, so that it can be tail-called at the
end of such functions as sys_setresuid().
Note that this function consumes the caller's reference to the new credentials.
The caller should _not_ call put_cred() on the new credentials afterwards.
Furthermore, once this function has been called on a new set of credentials,
those credentials may _not_ be changed further.
Should the security checks fail or some other error occur after prepare_creds()
has been called, then the following function should be invoked:
void abort_creds(struct cred *new);
This releases the lock on current->cred_replace_mutex that prepare_creds() got
and then releases the new credentials.
A typical credentials alteration function would look something like this:
int alter_suid(uid_t suid)
{
struct cred *new;
int ret;
new = prepare_creds();
if (!new)
return -ENOMEM;
new->suid = suid;
ret = security_alter_suid(new);
if (ret < 0) {
abort_creds(new);
return ret;
}
return commit_creds(new);
}
MANAGING CREDENTIALS
--------------------
There are some functions to help manage credentials:
(*) void put_cred(const struct cred *cred);
This releases a reference to the given set of credentials. If the
reference count reaches zero, the credentials will be scheduled for
destruction by the RCU system.
(*) const struct cred *get_cred(const struct cred *cred);
This gets a reference on a live set of credentials, returning a pointer to
that set of credentials.
(*) struct cred *get_new_cred(struct cred *cred);
This gets a reference on a set of credentials that is under construction
and is thus still mutable, returning a pointer to that set of credentials.
=====================
OPEN FILE CREDENTIALS
=====================
When a new file is opened, a reference is obtained on the opening task's
credentials and this is attached to the file struct as 'f_cred' in place of
'f_uid' and 'f_gid'. Code that used to access file->f_uid and file->f_gid
should now access file->f_cred->fsuid and file->f_cred->fsgid.
It is safe to access f_cred without the use of RCU or locking because the
pointer will not change over the lifetime of the file struct, and nor will the
contents of the cred struct pointed to, barring the exceptions listed above
(see the Task Credentials section).
=======================================
OVERRIDING THE VFS'S USE OF CREDENTIALS
=======================================
Under some circumstances it is desirable to override the credentials used by
the VFS, and that can be done by calling into such as vfs_mkdir() with a
different set of credentials. This is done in the following places:
(*) sys_faccessat().
(*) do_coredump().
(*) nfs4recover.c.

Overlay Support for PXA27x and later LCD controllers
====================================================
PXA27x and later processors support overlay1 and overlay2 on-top of the
base framebuffer (although under-neath the base is also possible). They
support palette and no-palette RGB formats, as well as YUV formats (only
available on overlay2). These overlays have dedicated DMA channels and
behave in a similar way as a framebuffer.
However, there are some differences between these overlay framebuffers
and normal framebuffers, as listed below:
1. overlay can start at a 32-bit word aligned position within the base
framebuffer, which means they have a start (x, y). This information
is encoded into var->nonstd (no, var->xoffset and var->yoffset are
not for such purpose).
2. overlay framebuffer is allocated dynamically according to specified
'struct fb_var_screeninfo', the amount is decided by:
var->xres_virtual * var->yres_virtual * bpp
bpp = 16 -- for RGB565 or RGBT555
= 24 -- for YUV444 packed
= 24 -- for YUV444 planar
= 16 -- for YUV422 planar (1 pixel = 1 Y + 1/2 Cb + 1/2 Cr)
= 12 -- for YUV420 planar (1 pixel = 1 Y + 1/4 Cb + 1/4 Cr)
NOTE:
a. overlay does not support panning in x-direction, thus
var->xres_virtual will always be equal to var->xres
b. line length of overlay(s) must be on a 32-bit word boundary,
for YUV planar modes, it is a requirement for the component
with minimum bits per pixel, e.g. for YUV420, Cr component
for one pixel is actually 2-bits, it means the line length
should be a multiple of 16-pixels
c. starting horizontal position (XPOS) should start on a 32-bit
word boundary, otherwise the fb_check_var() will just fail.
d. the rectangle of the overlay should be within the base plane,
otherwise fail
Applications should follow the sequence below to operate an overlay
framebuffer:
a. open("/dev/fb[1-2]", ...)
b. ioctl(fd, FBIOGET_VSCREENINFO, ...)
c. modify 'var' with desired parameters:
1) var->xres and var->yres
2) larger var->yres_virtual if more memory is required,
usually for double-buffering
3) var->nonstd for starting (x, y) and color format
4) var->{red, green, blue, transp} if RGB mode is to be used
d. ioctl(fd, FBIOPUT_VSCREENINFO, ...)
e. ioctl(fd, FBIOGET_FSCREENINFO, ...)
f. mmap
g. ...
3. for YUV planar formats, these are actually not supported within the
framebuffer framework, application has to take care of the offsets
and lengths of each component within the framebuffer.
4. var->nonstd is used to pass starting (x, y) position and color format,
the detailed bit fields are shown below:

Having too much or not enough data can be troublesome in diagnosing
an issue in the kernel. The file trace_entries is used to modify
an issue in the kernel. The file buffer_size_kb is used to modify
the size of the internal trace buffers. The number listed
is the number of entries that can be recorded per CPU. To know
the full size, multiply the number of possible CPUS with the
number of entries.
# cat /debug/tracing/trace_entries
65620
# cat /debug/tracing/buffer_size_kb
1408 (units kilobytes)
Note, to modify this, you must have tracing completely disabled. To do that,
echo "nop" into the current_tracer. If the current_tracer is not set
to "nop", an EINVAL error will be returned.
# echo nop > /debug/tracing/current_tracer
# echo 100000 > /debug/tracing/trace_entries
# cat /debug/tracing/trace_entries
100045
Notice that we echoed in 100,000 but the size is 100,045. The entries
are held in individual pages. It allocates the number of pages it takes
to fulfill the request. If more entries may fit on the last page
then they will be added.
# echo 1 > /debug/tracing/trace_entries
# cat /debug/tracing/trace_entries

This shows us that 85 entries can fit in a single page.
# echo 10000 > /debug/tracing/buffer_size_kb
# cat /debug/tracing/buffer_size_kb

The number of pages which will be allocated is limited to a percentage
of available memory. Allocating too much will produce an error.

8. Implementation note: user namespaces
User namespaces are intended to be hierarchical. But they are currently
only partially implemented. Each of those has ramifications for CFS.
First, since user namespaces are hierarchical, the /sys/kernel/uids
presentation is inadequate. Eventually we will likely want to use sysfs
tagging to provide private views of /sys/kernel/uids within each user
namespace.
Second, the hierarchical nature is intended to support completely
unprivileged use of user namespaces. So if using user groups, then
we want the users in a user namespace to be children of the user
who created it.
That is currently unimplemented. So instead, every user in a new
user namespace will receive 1024 shares just like any user in the
initial user namespace. Note that at the moment creation of a new
user namespace requires each of CAP_SYS_ADMIN, CAP_SETUID, and
CAP_SETGID.

Chelsio S3 iSCSI Driver for Linux
Introduction
============
The Chelsio T3 ASIC based Adapters (S310, S320, S302, S304, Mezz cards, etc.
series of products) supports iSCSI acceleration and iSCSI Direct Data Placement
(DDP) where the hardware handles the expensive byte touching operations, such
as CRC computation and verification, and direct DMA to the final host memory
destination:
- iSCSI PDU digest generation and verification
On transmitting, Chelsio S3 h/w computes and inserts the Header and
Data digest into the PDUs.
On receiving, Chelsio S3 h/w computes and verifies the Header and
Data digest of the PDUs.
- Direct Data Placement (DDP)
S3 h/w can directly place the iSCSI Data-In or Data-Out PDU's
payload into pre-posted final destination host-memory buffers based
on the Initiator Task Tag (ITT) in Data-In or Target Task Tag (TTT)
in Data-Out PDUs.
- PDU Transmit and Recovery
On transmitting, S3 h/w accepts the complete PDU (header + data)
from the host driver, computes and inserts the digests, decomposes
the PDU into multiple TCP segments if necessary, and transmit all
the TCP segments onto the wire. It handles TCP retransmission if
needed.
On receving, S3 h/w recovers the iSCSI PDU by reassembling TCP
segments, separating the header and data, calculating and verifying
the digests, then forwards the header to the host. The payload data,
if possible, will be directly placed into the pre-posted host DDP
buffer. Otherwise, the payload data will be sent to the host too.
The cxgb3i driver interfaces with open-iscsi initiator and provides the iSCSI
acceleration through Chelsio hardware wherever applicable.
Using the cxgb3i Driver
=======================
The following steps need to be taken to accelerates the open-iscsi initiator:
1. Load the cxgb3i driver: "modprobe cxgb3i"
The cxgb3i module registers a new transport class "cxgb3i" with open-iscsi.
* in the case of recompiling the kernel, the cxgb3i selection is located at
Device Drivers
SCSI device support --->
[*] SCSI low-level drivers --->
<M> Chelsio S3xx iSCSI support
2. Create an interface file located under /etc/iscsi/ifaces/ for the new
transport class "cxgb3i".
The content of the file should be in the following format:
iface.transport_name = cxgb3i
iface.net_ifacename = <ethX>
iface.ipaddress = <iscsi ip address>
* if iface.ipaddress is specified, <iscsi ip address> needs to be either the
same as the ethX's ip address or an address on the same subnet. Make
sure the ip address is unique in the network.
3. edit /etc/iscsi/iscsid.conf
The default setting for MaxRecvDataSegmentLength (131072) is too big,
replace "node.conn[0].iscsi.MaxRecvDataSegmentLength" to be a value no
bigger than 15360 (for example 8192):
node.conn[0].iscsi.MaxRecvDataSegmentLength = 8192
* The login would fail for a normal session if MaxRecvDataSegmentLength is
too big. A error message in the format of
"cxgb3i: ERR! MaxRecvSegmentLength <X> too big. Need to be <= <Y>."
would be logged to dmesg.
4. To direct open-iscsi traffic to go through cxgb3i's accelerated path,
"-I <iface file name>" option needs to be specified with most of the
iscsiadm command. <iface file name> is the transport interface file created
in step 2.

This file describes the configuration and behavior of KGDB for the SH
kernel. Based on a description from Henry Bell <henry.bell@st.com>, it
has been modified to account for quirks in the current implementation.
Version
=======
This version of KGDB was written for 2.4.xx kernels for the SH architecture.
Further documentation is available from the linux-sh project website.
Debugging Setup: Host
======================
The two machines will be connected together via a serial line - this
should be a null modem cable i.e. with a twist.
On your DEVELOPMENT machine, go to your kernel source directory and
build the kernel, enabling KGDB support in the "kernel hacking" section.
This includes the KGDB code, and also makes the kernel be compiled with
the "-g" option set -- necessary for debugging.
To install this new kernel, use the following installation procedure.
Decide on which tty port you want the machines to communicate, then
cable them up back-to-back using the null modem. On the DEVELOPMENT
machine, you may wish to create an initialization file called .gdbinit
(in the kernel source directory or in your home directory) to execute
commonly-used commands at startup.
A minimal .gdbinit might look like this:
file vmlinux
set remotebaud 115200
target remote /dev/ttyS0
Change the "target" definition so that it specifies the tty port that
you intend to use. Change the "remotebaud" definition to match the
data rate that you are going to use for the com line (115200 is the
default).
Debugging Setup: Target
========================
By default, the KGDB stub will communicate with the host GDB using
ttySC1 at 115200 baud, 8 databits, no parity; these defaults can be
changed in the kernel configuration. As the kernel starts up, KGDB will
initialize so that breakpoints, kernel segfaults, and so forth will
generally enter the debugger.
This behavior can be modified by including the "kgdb" option in the
kernel command line; this option has the general form:
kgdb=<ttyspec>,<action>
The <ttyspec> indicates the port to use, and can optionally specify
baud, parity and databits -- e.g. "ttySC0,9600N8" or "ttySC1,19200".
The <action> can be "halt" or "disabled". The "halt" action enters the
debugger via a breakpoint as soon as kgdb is initialized; the "disabled"
action causes kgdb to ignore kernel segfaults and such until explicitly
entered by a breakpoint in the code or by external action (sysrq or NMI).
(Both <ttyspec> and <action> can appear alone, w/o the separating comma.)
For example, if you wish to debug early in kernel startup code, you
might specify the halt option:
kgdb=halt
Boot the TARGET machine, which will appear to hang.
On your DEVELOPMENT machine, cd to the source directory and run the gdb
program. (This is likely to be a cross GDB which runs on your host but
is built for an SH target.) If everything is working correctly you
should see gdb print out a few lines indicating that a breakpoint has
been taken. It will actually show a line of code in the target kernel
inside the gdbstub activation code.
NOTE: BE SURE TO TERMINATE OR SUSPEND any other host application which
may be using the same serial port (for example, a terminal emulator you
have been using to connect to the target boot code.) Otherwise, data
from the target may not all get to GDB!
You can now use whatever gdb commands you like to set breakpoints.
Enter "continue" to start your target machine executing again. At this
point the target system will run at full speed until it encounters
your breakpoint or gets a segment violation in the kernel, or whatever.
Serial Ports: KGDB, Console
============================
This version of KGDB may not gracefully handle conflict with other
drivers in the kernel using the same port. If KGDB is configured on the
same port (and with the same parameters) as the kernel console, or if
CONFIG_SH_KGDB_CONSOLE is configured, things should be fine (though in
some cases console messages may appear twice through GDB). But if the
KGDB port is not the kernel console and used by another serial driver
which assumes different serial parameters (e.g. baud rate) KGDB may not
recover.
Also, when KGDB is entered via sysrq-g (requires CONFIG_KGDB_SYSRQ) and
the kgdb port uses the same port as the console, detaching GDB will not
restore the console to working order without the port being re-opened.
Another serious consequence of this is that GDB currently CANNOT break
into KGDB externally (e.g. via ^C or <BREAK>); unless a breakpoint or
error is encountered, the only way to enter KGDB after the initial halt
(see above) is via NMI (CONFIG_KGDB_NMI) or sysrq-g (CONFIG_KGDB_SYSRQ).
Code is included for the basic Hitachi Solution Engine boards to allow
the use of ttyS0 for KGDB if desired; this is less robust, but may be
useful in some cases. (This cannot be selected using the config file,
but only through the kernel command line, e.g. "kgdb=ttyS0", though the
configured defaults for baud rate etc. still apply if not overridden.)
If gdbstub Does Not Work
========================
If it doesn't work, you will have to troubleshoot it. Do the easy
things first like double checking your cabling and data rates. You
might try some non-kernel based programs to see if the back-to-back
connection works properly. Just something simple like cat /etc/hosts
/dev/ttyS0 on one machine and cat /dev/ttyS0 on the other will tell you
if you can send data from one machine to the other. There is no point
in tearing out your hair in the kernel if the line doesn't work.
If you need to debug the GDB/KGDB communication itself, the gdb commands
"set debug remote 1" and "set debug serial 1" may be useful, but be
warned: they produce a lot of output.
Threads
=======
Each process in a target machine is seen as a gdb thread. gdb thread related
commands (info threads, thread n) can be used. CONFIG_KGDB_THREAD must
be defined for this to work.
In this version, kgdb reports PID_MAX (32768) as the process ID for the
idle process (pid 0), since GDB does not accept 0 as an ID.
Detaching (exiting KGDB)
=========================
There are two ways to resume full-speed target execution: "continue" and
"detach". With "continue", GDB inserts any specified breakpoints in the
target code and resumes execution; the target is still in "gdb mode".
If a breakpoint or other debug event (e.g. NMI) happens, the target
halts and communicates with GDB again, which is waiting for it.
With "detach", GDB does *not* insert any breakpoints; target execution
is resumed and GDB stops communicating (does not wait for the target).
In this case, the target is no longer in "gdb mode" -- for example,
console messages no longer get sent separately to the KGDB port, or
encapsulated for GDB. If a debug event (e.g. NMI) occurs, the target
will re-enter "gdb mode" and will display this fact on the console; you
must give a new "target remote" command to gdb.
NOTE: TO AVOID LOSSING CONSOLE MESSAGES IN CASE THE KERNEL CONSOLE AND
KGDB USING THE SAME PORT, THE TARGET WAITS FOR ANY INPUT CHARACTER ON
THE KGDB PORT AFTER A DETACH COMMAND. For example, after the detach you
could start a terminal emulator on the same host port and enter a <cr>;
however, this program must then be terminated or suspended in order to
use GBD again if KGDB is re-entered.

Each codec may have a model table for different configurations.
If your machine isn't listed there, the default (usually minimal)
configuration is set up. You can pass "model=<name>" option to
specify a certain model in such a case. There are different
models depending on the codec chip.

models depending on the codec chip. The list of available models
is found in HD-Audio-Models.txt
The model name "genric" is treated as a special case. When this
model is given, the driver uses the generic codec parser without
"codec-patch". It's sometimes good for testing and debugging.
If the default configuration doesn't work and one of the above
matches with your device, report it together with the PCI
subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel
matches with your device, report it together with alsa-info.sh

MORE NOTES ON HD-AUDIO DRIVER
=============================
Takashi Iwai <tiwai@suse.de>
GENERAL
-------
HD-audio is the new standard on-board audio component on modern PCs
after AC97. Although Linux has been supporting HD-audio since long
time ago, there are often problems with new machines. A part of the
problem is broken BIOS, and the rest is the driver implementation.
This document explains the brief trouble-shooting and debugging
methods for the HD-audio hardware.
The HD-audio component consists of two parts: the controller chip and
the codec chips on the HD-audio bus. Linux provides a single driver
for all controllers, snd-hda-intel. Although the driver name contains
a word of a well-known harware vendor, it's not specific to it but for
all controller chips by other companies. Since the HD-audio
controllers are supposed to be compatible, the single snd-hda-driver
should work in most cases. But, not surprisingly, there are known
bugs and issues specific to each controller type. The snd-hda-intel
driver has a bunch of workarounds for these as described below.
A controller may have multiple codecs. Usually you have one audio
codec and optionally one modem codec. In theory, there might be
multiple audio codecs, e.g. for analog and digital outputs, and the
driver might not work properly because of conflict of mixer elements.
This should be fixed in future if such hardware really exists.
The snd-hda-intel driver has several different codec parsers depending
on the codec. It has a generic parser as a fallback, but this
functionality is fairly limited until now. Instead of the generic
parser, usually the codec-specific parser (coded in patch_*.c) is used
for the codec-specific implementations. The details about the
codec-specific problems are explained in the later sections.
If you are interested in the deep debugging of HD-audio, read the
HD-audio specification at first. The specification is found on
Intel's web page, for example:
- http://www.intel.com/standards/hdaudio/
HD-AUDIO CONTROLLER
-------------------
DMA-Position Problem
~~~~~~~~~~~~~~~~~~~~
The most common problem of the controller is the inaccurate DMA
pointer reporting. The DMA pointer for playback and capture can be
read in two ways, either via a LPIB register or via a position-buffer
map. As default the driver tries to read from the io-mapped
position-buffer, and falls back to LPIB if the position-buffer appears
dead. However, this detection isn't perfect on some devices. In such
a case, you can change the default method via `position_fix` option.
`position_fix=1` means to use LPIB method explicitly.
`position_fix=2` means to use the position-buffer. 0 is the default
value, the automatic check and fallback to LPIB as described in the
above. If you get a problem of repeated sounds, this option might
help.
In addition to that, every controller is known to be broken regarding
the wake-up timing. It wakes up a few samples before actually
processing the data on the buffer. This caused a lot of problems, for
example, with ALSA dmix or JACK. Since 2.6.27 kernel, the driver puts
an artificial delay to the wake up timing. This delay is controlled
via `bdl_pos_adj` option.
When `bdl_pos_adj` is a negative value (as default), it's assigned to
an appropriate value depending on the controller chip. For Intel
chips, it'd be 1 while it'd be 32 for others. Usually this works.
Only in case it doesn't work and you get warning messages, you should
change this parameter to other values.
Codec-Probing Problem
~~~~~~~~~~~~~~~~~~~~~
A less often but a more severe problem is the codec probing. When
BIOS reports the available codec slots wrongly, the driver gets
confused and tries to access the non-existing codec slot. This often
results in the total screw-up, and destructs the further communication
with the codec chips. The symptom appears usually as error messages
like:
------------------------------------------------------------------------
hda_intel: azx_get_response timeout, switching to polling mode:
last cmd=0x12345678
hda_intel: azx_get_response timeout, switching to single_cmd mode:
last cmd=0x12345678
------------------------------------------------------------------------
The first line is a warning, and this is usually relatively harmless.
It means that the codec response isn't notified via an IRQ. The
driver uses explicit polling method to read the response. It gives
very slight CPU overhead, but you'd unlikely notice it.
The second line is, however, a fatal error. If this happens, usually
it means that something is really wrong. Most likely you are
accessing a non-existing codec slot.
Thus, if the second error message appears, try to narrow the probed
codec slots via `probe_mask` option. It's a bitmask, and each bit
corresponds to the codec slot. For example, to probe only the first
slot, pass `probe_mask=1`. For the first and the third slots, pass
`probe_mask=5` (where 5 = 1 | 4), and so on.
Since 2.6.29 kernel, the driver has a more robust probing method, so
this error might happen rarely, though.
Interrupt Handling
~~~~~~~~~~~~~~~~~~
In rare but some cases, the interrupt isn't properly handled as
default. You would notice this by the DMA transfer error reported by
ALSA PCM core, for example. Using MSI might help in such a case.
Pass `enable_msi=1` option for enabling MSI.
HD-AUDIO CODEC
--------------
Model Option
~~~~~~~~~~~~
The most common problem regarding the HD-audio driver is the
unsupported codec features or the mismatched device configuration.
Most of codec-specific code has several preset models, either to
override the BIOS setup or to provide more comprehensive features.
The driver checks PCI SSID and looks through the static configuration
table until any matching entry is found. If you have a new machine,
you may see a message like below:
------------------------------------------------------------------------
hda_codec: Unknown model for ALC880, trying auto-probe from BIOS...
------------------------------------------------------------------------
Even if you see such a message, DON'T PANIC. Take a deep breath and
keep your towel. First of all, it's an informational message, no
warning, no error. This means that the PCI SSID of your device isn't
listed in the known preset model (white-)list. But, this doesn't mean
that the driver is broken. Many codec-drivers provide the automatic
configuration mechanism based on the BIOS setup.
The HD-audio codec has usually "pin" widgets, and BIOS sets the default
configuration of each pin, which indicates the location, the
connection type, the jack color, etc. The HD-audio driver can guess
the right connection judging from these default configuration values.
However -- some codec-support codes, such as patch_analog.c, don't
support the automatic probing (yet as of 2.6.28). And, BIOS is often,
yes, pretty often broken. It sets up wrong values and screws up the
driver.
The preset model is provided basically to overcome such a situation.
When the matching preset model is found in the white-list, the driver
assumes the static configuration of that preset and builds the mixer
elements and PCM streams based on the static information. Thus, if
you have a newer machine with a slightly different PCI SSID from the
existing one, you may have a good chance to re-use the same model.
You can pass the `model` option to specify the preset model instead of
PCI SSID look-up.
What `model` option values are available depends on the codec chip.
Check your codec chip from the codec proc file (see "Codec Proc-File"
section below). It will show the vendor/product name of your codec
chip. Then, see Documentation/sound/alsa/HD-Audio-Modelstxt file,
the section of HD-audio driver. You can find a list of codecs
and `model` options belonging to each codec. For example, for Realtek
ALC262 codec chip, pass `model=ultra` for devices that are compatible
with Samsung Q1 Ultra.
Thus, the first thing you can do for any brand-new, unsupported and
non-working HD-audio hardware is to check HD-audio codec and several
different `model` option values. If you have a luck, some of them
might suit with your device well.
Some codecs such as ALC880 have a special model option `model=test`.
This configures the driver to provide as many mixer controls as
possible for every single pin feature except for the unsolicited
events (and maybe some other specials). Adjust each mixer element and
try the I/O in the way of trial-and-error until figuring out the whole
I/O pin mappings.
Note that `model=generic` has a special meaning. It means to use the
generic parser regardless of the codec. Usually the codec-specific
parser is much better than the generic parser (as now). Thus this
option is more about the debugging purpose.
Speaker and Headphone Output
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
One of the most frequent (and obvious) bugs with HD-audio is the
silent output from either or both of a built-in speaker and a
headphone jack. In general, you should try a headphone output at
first. A speaker output often requires more additional controls like
the external amplifier bits. Thus a headphone output has a slightly
better chance.
Before making a bug report, double-check whether the mixer is set up
correctly. The recent version of snd-hda-intel driver provides mostly
"Master" volume control as well as "Front" volume (where Front
indicates the front-channels). In addition, there can be individual
"Headphone" and "Speaker" controls.
Ditto for the speaker output. There can be "External Amplifier"
switch on some codecs. Turn on this if present.
Another related problem is the automatic mute of speaker output by
headphone plugging. This feature is implemented in most cases, but
not on every preset model or codec-support code.
In anyway, try a different model option if you have such a problem.
Some other models may match better and give you more matching
functionality. If none of the available models works, send a bug
report. See the bug report section for details.
If you are masochistic enough to debug the driver problem, note the
following:
- The speaker (and the headphone, too) output often requires the
external amplifier. This can be set usually via EAPD verb or a
certain GPIO. If the codec pin supports EAPD, you have a better
chance via SET_EAPD_BTL verb (0x70c). On others, GPIO pin (mostly
it's either GPIO0 or GPIO1) may turn on/off EAPD.
- Some Realtek codecs require special vendor-specific coefficients to
turn on the amplifier. See patch_realtek.c.
- IDT codecs may have extra power-enable/disable controls on each
analog pin. See patch_sigmatel.c.
- Very rare but some devices don't accept the pin-detection verb until
triggered. Issuing GET_PIN_SENSE verb (0xf09) may result in the
codec-communication stall. Some examples are found in
patch_realtek.c.
Capture Problems
~~~~~~~~~~~~~~~~
The capture problems are often because of missing setups of mixers.
Thus, before submitting a bug report, make sure that you set up the
mixer correctly. For example, both "Capture Volume" and "Capture
Switch" have to be set properly in addition to the right "Capture
Source" or "Input Source" selection. Some devices have "Mic Boost"
volume or switch.
When the PCM device is opened via "default" PCM (without pulse-audio
plugin), you'll likely have "Digital Capture Volume" control as well.
This is provided for the extra gain/attenuation of the signal in
software, especially for the inputs without the hardware volume
control such as digital microphones. Unless really needed, this
should be set to exactly 50%, corresponding to 0dB -- neither extra
gain nor attenuation. When you use "hw" PCM, i.e., a raw access PCM,
this control will have no influence, though.
It's known that some codecs / devices have fairly bad analog circuits,
and the recorded sound contains a certain DC-offset. This is no bug
of the driver.
Most of modern laptops have no analog CD-input connection. Thus, the
recording from CD input won't work in many cases although the driver
provides it as the capture source. Use CDDA instead.
The automatic switching of the built-in and external mic per plugging
is implemented on some codec models but not on every model. Partly
because of my laziness but mostly lack of testers. Feel free to
submit the improvement patch to the author.
Direct Debugging
~~~~~~~~~~~~~~~~
If no model option gives you a better result, and you are a tough guy
to fight against evil, try debugging via hitting the raw HD-audio
codec verbs to the device. Some tools are available: hda-emu and
hda-analyzer. The detailed description is found in the sections
below. You'd need to enable hwdep for using these tools. See "Kernel
Configuration" section.
OTHER ISSUES
------------
Kernel Configuration
~~~~~~~~~~~~~~~~~~~~
In general, I recommend you to enable the sound debug option,
`CONFIG_SND_DEBUG=y`, no matter whether you are debugging or not.
This enables snd_printd() macro and others, and you'll get additional
kernel messages at probing.
In addition, you can enable `CONFIG_SND_DEBUG_VERBOSE=y`. But this
will give you far more messages. Thus turn this on only when you are
sure to want it.
Don't forget to turn on the appropriate `CONFIG_SND_HDA_CODEC_*`
options. Note that each of them corresponds to the codec chip, not
the controller chip. Thus, even if lspci shows the Nvidia controller,
you may need to choose the option for other vendors. If you are
unsure, just select all yes.
`CONFIG_SND_HDA_HWDEP` is a useful option for debugging the driver.
When this is enabled, the driver creates hardware-dependent devices
(one per each codec), and you have a raw access to the device via
these device files. For example, `hwC0D2` will be created for the
codec slot #2 of the first card (#0). For debug-tools such as
hda-verb and hda-analyzer, the hwdep device has to be enabled.
Thus, it'd be better to turn this on always.
`CONFIG_SND_HDA_RECONFIG` is a new option, and this depends on the
hwdep option above. When enabled, you'll have some sysfs files under
the corresponding hwdep directory. See "HD-audio reconfiguration"
section below.
`CONFIG_SND_HDA_POWER_SAVE` option enables the power-saving feature.
See "Power-saving" section below.
Codec Proc-File
~~~~~~~~~~~~~~~
The codec proc-file is a treasure-chest for debugging HD-audio.
It shows most of useful information of each codec widget.
The proc file is located in /proc/asound/card*/codec#*, one file per
each codec slot. You can know the codec vendor, product id and
names, the type of each widget, capabilities and so on.
This file, however, doesn't show the jack sensing state, so far. This
is because the jack-sensing might be depending on the trigger state.
This file will be picked up by the debug tools, and also it can be fed
to the emulator as the primary codec information. See the debug tools
section below.
This proc file can be also used to check whether the generic parser is
used. When the generic parser is used, the vendor/product ID name
will appear as "Realtek ID 0262", instead of "Realtek ALC262".
HD-Audio Reconfiguration
~~~~~~~~~~~~~~~~~~~~~~~~
This is an experimental feature to allow you re-configure the HD-audio
codec dynamically without reloading the driver. The following sysfs
files are available under each codec-hwdep device directory (e.g.
/sys/class/sound/hwC0D0):
vendor_id::
Shows the 32bit codec vendor-id hex number. You can change the
vendor-id value by writing to this file.
subsystem_id::
Shows the 32bit codec subsystem-id hex number. You can change the
subsystem-id value by writing to this file.
revision_id::
Shows the 32bit codec revision-id hex number. You can change the
revision-id value by writing to this file.
afg::
Shows the AFG ID. This is read-only.
mfg::
Shows the MFG ID. This is read-only.
name::
Shows the codec name string. Can be changed by writing to this
file.
modelname::
Shows the currently set `model` option. Can be changed by writing
to this file.
init_verbs::
The extra verbs to execute at initialization. You can add a verb by
writing to this file. Pass tree numbers, nid, verb and parameter.
hints::
Shows hint strings for codec parsers for any use. Right now it's
not used.
reconfig::
Triggers the codec re-configuration. When any value is written to
this file, the driver re-initialize and parses the codec tree
again. All the changes done by the sysfs entries above are taken
into account.
clear::
Resets the codec, removes the mixer elements and PCM stuff of the
specified codec, and clear all init verbs and hints.
Power-Saving
~~~~~~~~~~~~
The power-saving is a kind of auto-suspend of the device. When the
device is inactive for a certain time, the device is automatically
turned off to save the power. The time to go down is specified via
`power_save` module option, and this option can be changed dynamically
via sysfs.
The power-saving won't work when the analog loopback is enabled on
some codecs. Make sure that you mute all unneeded signal routes when
you want the power-saving.
The power-saving feature might cause audible click noises at each
power-down/up depending on the device. Some of them might be
solvable, but some are hard, I'm afraid. Some distros such as
openSUSE enables the power-saving feature automatically when the power
cable is unplugged. Thus, if you hear noises, suspect first the
power-saving. See /sys/module/snd_hda_intel/parameters/power_save to
check the current value. If it's non-zero, the feature is turned on.
Development Tree
~~~~~~~~~~~~~~~~
The latest development codes for HD-audio are found on sound git tree:
- git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git
The master branch or for-next branches can be used as the main
development branches in general while the HD-audio specific patches
are committed in topic/hda branch.
If you are using the latest Linus tree, it'd be better to pull the
above GIT tree onto it. If you are using the older kernels, an easy
way to try the latest ALSA code is to build from the snapshot
tarball. There are daily tarballs and the latest snapshot tarball.
All can be built just like normal alsa-driver release packages, that
is, installed via the usual spells: configure, make and make
install(-modules). See INSTALL in the package. The snapshot tarballs
are found at:
- ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/
Sending a Bug Report
~~~~~~~~~~~~~~~~~~~~
If any model or module options don't work for your device, it's time
to send a bug report to the developers. Give the following in your
bug report:
- Hardware vendor, product and model names
- Kernel version (and ALSA-driver version if you built externally)
- `alsa-info.sh` output; run with `--no-upload` option. See the
section below about alsa-info
If it's a regression, at best, send alsa-info outputs of both working
and non-working kernels. This is really helpful because we can
compare the codec registers directly.
Send a bug report either the followings:
kernel-bugzilla::
http://bugme.linux-foundation.org/
alsa-devel ML::
alsa-devel@alsa-project.org
DEBUG TOOLS
-----------
This section describes some tools available for debugging HD-audio
problems.
alsa-info
~~~~~~~~~
The script `alsa-info.sh` is a very useful tool to gather the audio
device information. You can fetch the latest version from:
- http://www.alsa-project.org/alsa-info.sh
Run this script as root, and it will gather the important information
such as the module lists, module parameters, proc file contents
including the codec proc files, mixer outputs and the control
elements. As default, it will store the information onto a web server
on alsa-project.org. But, if you send a bug report, it'd be better to
run with `--no-upload` option, and attach the generated file.
There are some other useful options. See `--help` option output for
details.
hda-verb
~~~~~~~~
hda-verb is a tiny program that allows you to access the HD-audio
codec directly. You can execute a raw HD-audio codec verb with this.
This program accesses the hwdep device, thus you need to enable the
kernel config `CONFIG_SND_HDA_HWDEP=y` beforehand.
The hda-verb program takes four arguments: the hwdep device file, the
widget NID, the verb and the parameter. When you access to the codec
on the slot 2 of the card 0, pass /dev/snd/hwC0D2 to the first
argument, typically. (However, the real path name depends on the
system.)
The second parameter is the widget number-id to access. The third
parameter can be either a hex/digit number or a string corresponding
to a verb. Similarly, the last parameter is the value to write, or
can be a string for the parameter type.
------------------------------------------------------------------------
% hda-verb /dev/snd/hwC0D0 0x12 0x701 2
nid = 0x12, verb = 0x701, param = 0x2
value = 0x0
% hda-verb /dev/snd/hwC0D0 0x0 PARAMETERS VENDOR_ID
nid = 0x0, verb = 0xf00, param = 0x0
value = 0x10ec0262
% hda-verb /dev/snd/hwC0D0 2 set_a 0xb080
nid = 0x2, verb = 0x300, param = 0xb080
value = 0x0
------------------------------------------------------------------------
Although you can issue any verbs with this program, the driver state
won't be always updated. For example, the volume values are usually
cached in the driver, and thus changing the widget amp value directly
via hda-verb won't change the mixer value.
The hda-verb program is found in the ftp directory:
- ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/misc/
Also a git repository is available:
- git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/hda-verb.git
See README file in the tarball for more details about hda-verb
program.
hda-analyzer
~~~~~~~~~~~~
hda-analyzer provides a graphical interface to access the raw HD-audio
control, based on pyGTK2 binding. It's a more powerful version of
hda-verb. The program gives you an easy-to-use GUI stuff for showing
the widget information and adjusting the amp values, as well as the
proc-compatible output.
The hda-analyzer is a part of alsa.git repository in
alsa-project.org:
- http://git.alsa-project.org/?p=alsa.git;a=tree;f=hda-analyzer
Codecgraph
~~~~~~~~~~
Codecgraph is a utility program to generate a graph and visualizes the
codec-node connection of a codec chip. It's especially useful when
you analyze or debug a codec without a proper datasheet. The program
parses the given codec proc file and converts to SVG via graphiz
program.
The tarball and GIT trees are found in the web page at:
- http://helllabs.org/codecgraph/
hda-emu
~~~~~~~
hda-emu is an HD-audio emulator. The main purpose of this program is
to debug an HD-audio codec without the real hardware. Thus, it
doesn't emulate the behavior with the real audio I/O, but it just
dumps the codec register changes and the ALSA-driver internal changes
at probing and operating the HD-audio driver.
The program requires a codec proc-file to simulate. Get a proc file
for the target codec beforehand, or pick up an example codec from the
codec proc collections in the tarball. Then, run the program with the
proc file, and the hda-emu program will start parsing the codec file
and simulates the HD-audio driver:
------------------------------------------------------------------------
% hda-emu codecs/stac9200-dell-d820-laptop
# Parsing..
hda_codec: Unknown model for STAC9200, using BIOS defaults
hda_codec: pin nid 08 bios pin config 40c003fa
....
------------------------------------------------------------------------
The program gives you only a very dumb command-line interface. You
can get a proc-file dump at the current state, get a list of control
(mixer) elements, set/get the control element value, simulate the PCM
operation, the jack plugging simulation, etc.
The package is found in:
- ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/misc/
A git repository is available:
- git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/hda-emu.git
See README file in the tarball for more details about hda-emu
program.

* Purpose of tracepoints
A tracepoint placed in code provides a hook to call a function (probe) that you
can provide at runtime. A tracepoint can be "on" (a probe is connected to it) or
"off" (no probe is attached). When a tracepoint is "off" it has no effect,
except for adding a tiny time penalty (checking a condition for a branch) and
space penalty (adding a few bytes for the function call at the end of the
instrumented function and adds a data structure in a separate section). When a
tracepoint is "on", the function you provide is called each time the tracepoint
is executed, in the execution context of the caller. When the function provided
ends its execution, it returns to the caller (continuing from the tracepoint
site).

compiler. Tracepoints can be put in inline functions, inlined static functions,
and unrolled loops as well as regular functions.
tracepoint_synchronize_unregister() must be called before the end of
the module exit function to make sure there is no caller left using
the probe. This, and the fact that preemption is disabled around the
probe call, make sure that probe removal and module unload are safe.
See the "Probe example" section below for a sample probe module.
The naming scheme "subsys_event" is suggested here as a convention intended
to limit collisions. Tracepoint names are global to the kernel: they are
considered as being the same whether they are in the core kernel image or in
modules.
The tracepoint mechanism supports inserting multiple instances of the
same tracepoint, but a single definition must be made of a given
tracepoint name over all the kernel to make sure no type conflict will
occur. Name mangling of the tracepoints is done using the prototypes
to make sure typing is correct. Verification of probe type correctness
is done at the registration site by the compiler. Tracepoints can be
put in inline functions, inlined static functions, and unrolled loops
as well as regular functions.

If the tracepoint has to be used in kernel modules, an
EXPORT_TRACEPOINT_SYMBOL_GPL() or EXPORT_TRACEPOINT_SYMBOL() can be
used to export the defined tracepoints.

Overview of the V4L2 driver framework
=====================================
This text documents the various structures provided by the V4L2 framework and
their relationships.
Introduction
------------
The V4L2 drivers tend to be very complex due to the complexity of the
hardware: most devices have multiple ICs, export multiple device nodes in
/dev, and create also non-V4L2 devices such as DVB, ALSA, FB, I2C and input
(IR) devices.
Especially the fact that V4L2 drivers have to setup supporting ICs to
do audio/video muxing/encoding/decoding makes it more complex than most.
Usually these ICs are connected to the main bridge driver through one or
more I2C busses, but other busses can also be used. Such devices are
called 'sub-devices'.
For a long time the framework was limited to the video_device struct for
creating V4L device nodes and video_buf for handling the video buffers
(note that this document does not discuss the video_buf framework).
This meant that all drivers had to do the setup of device instances and
connecting to sub-devices themselves. Some of this is quite complicated
to do right and many drivers never did do it correctly.
There is also a lot of common code that could never be refactored due to
the lack of a framework.
So this framework sets up the basic building blocks that all drivers
need and this same framework should make it much easier to refactor
common code into utility functions shared by all drivers.
Structure of a driver
---------------------
All drivers have the following structure:
1) A struct for each device instance containing the device state.
2) A way of initializing and commanding sub-devices (if any).
3) Creating V4L2 device nodes (/dev/videoX, /dev/vbiX, /dev/radioX and
/dev/vtxX) and keeping track of device-node specific data.
4) Filehandle-specific structs containing per-filehandle data.
This is a rough schematic of how it all relates:
device instances
|
+-sub-device instances
|
\-V4L2 device nodes
|
\-filehandle instances
Structure of the framework
--------------------------
The framework closely resembles the driver structure: it has a v4l2_device
struct for the device instance data, a v4l2_subdev struct to refer to
sub-device instances, the video_device struct stores V4L2 device node data
and in the future a v4l2_fh struct will keep track of filehandle instances
(this is not yet implemented).
struct v4l2_device
------------------
Each device instance is represented by a struct v4l2_device (v4l2-device.h).
Very simple devices can just allocate this struct, but most of the time you
would embed this struct inside a larger struct.
You must register the device instance:
v4l2_device_register(struct device *dev, struct v4l2_device *v4l2_dev);
Registration will initialize the v4l2_device struct and link dev->driver_data
to v4l2_dev. Registration will also set v4l2_dev->name to a value derived from
dev (driver name followed by the bus_id, to be precise). You may change the
name after registration if you want.
The first 'dev' argument is normally the struct device pointer of a pci_dev,
usb_device or platform_device.
You unregister with:
v4l2_device_unregister(struct v4l2_device *v4l2_dev);
Unregistering will also automatically unregister all subdevs from the device.
Sometimes you need to iterate over all devices registered by a specific
driver. This is usually the case if multiple device drivers use the same
hardware. E.g. the ivtvfb driver is a framebuffer driver that uses the ivtv
hardware. The same is true for alsa drivers for example.
You can iterate over all registered devices as follows:
static int callback(struct device *dev, void *p)
{
struct v4l2_device *v4l2_dev = dev_get_drvdata(dev);
/* test if this device was inited */
if (v4l2_dev == NULL)
return 0;
...
return 0;
}
int iterate(void *p)
{
struct device_driver *drv;
int err;
/* Find driver 'ivtv' on the PCI bus.
pci_bus_type is a global. For USB busses use usb_bus_type. */
drv = driver_find("ivtv", &pci_bus_type);
/* iterate over all ivtv device instances */
err = driver_for_each_device(drv, NULL, p, callback);
put_driver(drv);
return err;
}
Sometimes you need to keep a running counter of the device instance. This is
commonly used to map a device instance to an index of a module option array.
The recommended approach is as follows:
static atomic_t drv_instance = ATOMIC_INIT(0);
static int __devinit drv_probe(struct pci_dev *dev,
const struct pci_device_id *pci_id)
{
...
state->instance = atomic_inc_return(&drv_instance) - 1;
}
struct v4l2_subdev
------------------
Many drivers need to communicate with sub-devices. These devices can do all
sort of tasks, but most commonly they handle audio and/or video muxing,
encoding or decoding. For webcams common sub-devices are sensors and camera
controllers.
Usually these are I2C devices, but not necessarily. In order to provide the
driver with a consistent interface to these sub-devices the v4l2_subdev struct
(v4l2-subdev.h) was created.
Each sub-device driver must have a v4l2_subdev struct. This struct can be
stand-alone for simple sub-devices or it might be embedded in a larger struct
if more state information needs to be stored. Usually there is a low-level
device struct (e.g. i2c_client) that contains the device data as setup
by the kernel. It is recommended to store that pointer in the private
data of v4l2_subdev using v4l2_set_subdevdata(). That makes it easy to go
from a v4l2_subdev to the actual low-level bus-specific device data.
You also need a way to go from the low-level struct to v4l2_subdev. For the
common i2c_client struct the i2c_set_clientdata() call is used to store a
v4l2_subdev pointer, for other busses you may have to use other methods.
From the bridge driver perspective you load the sub-device module and somehow
obtain the v4l2_subdev pointer. For i2c devices this is easy: you call
i2c_get_clientdata(). For other busses something similar needs to be done.
Helper functions exists for sub-devices on an I2C bus that do most of this
tricky work for you.
Each v4l2_subdev contains function pointers that sub-device drivers can
implement (or leave NULL if it is not applicable). Since sub-devices can do
so many different things and you do not want to end up with a huge ops struct
of which only a handful of ops are commonly implemented, the function pointers
are sorted according to category and each category has its own ops struct.
The top-level ops struct contains pointers to the category ops structs, which
may be NULL if the subdev driver does not support anything from that category.
It looks like this:
struct v4l2_subdev_core_ops {
int (*g_chip_ident)(struct v4l2_subdev *sd, struct v4l2_chip_ident *chip);
int (*log_status)(struct v4l2_subdev *sd);
int (*init)(struct v4l2_subdev *sd, u32 val);
...
};
struct v4l2_subdev_tuner_ops {
...
};
struct v4l2_subdev_audio_ops {
...
};
struct v4l2_subdev_video_ops {
...
};
struct v4l2_subdev_ops {
const struct v4l2_subdev_core_ops *core;
const struct v4l2_subdev_tuner_ops *tuner;
const struct v4l2_subdev_audio_ops *audio;
const struct v4l2_subdev_video_ops *video;
};
The core ops are common to all subdevs, the other categories are implemented
depending on the sub-device. E.g. a video device is unlikely to support the
audio ops and vice versa.
This setup limits the number of function pointers while still making it easy
to add new ops and categories.
A sub-device driver initializes the v4l2_subdev struct using:
v4l2_subdev_init(subdev, &ops);
Afterwards you need to initialize subdev->name with a unique name and set the
module owner. This is done for you if you use the i2c helper functions.
A device (bridge) driver needs to register the v4l2_subdev with the
v4l2_device:
int err = v4l2_device_register_subdev(device, subdev);
This can fail if the subdev module disappeared before it could be registered.
After this function was called successfully the subdev->dev field points to
the v4l2_device.
You can unregister a sub-device using:
v4l2_device_unregister_subdev(subdev);
Afterwards the subdev module can be unloaded and subdev->dev == NULL.
You can call an ops function either directly:
err = subdev->ops->core->g_chip_ident(subdev, &chip);
but it is better and easier to use this macro:
err = v4l2_subdev_call(subdev, core, g_chip_ident, &chip);
The macro will to the right NULL pointer checks and returns -ENODEV if subdev
is NULL, -ENOIOCTLCMD if either subdev->core or subdev->core->g_chip_ident is
NULL, or the actual result of the subdev->ops->core->g_chip_ident ops.
It is also possible to call all or a subset of the sub-devices:
v4l2_device_call_all(dev, 0, core, g_chip_ident, &chip);
Any subdev that does not support this ops is skipped and error results are
ignored. If you want to check for errors use this:
err = v4l2_device_call_until_err(dev, 0, core, g_chip_ident, &chip);
Any error except -ENOIOCTLCMD will exit the loop with that error. If no
errors (except -ENOIOCTLCMD) occured, then 0 is returned.
The second argument to both calls is a group ID. If 0, then all subdevs are
called. If non-zero, then only those whose group ID match that value will
be called. Before a bridge driver registers a subdev it can set subdev->grp_id
to whatever value it wants (it's 0 by default). This value is owned by the
bridge driver and the sub-device driver will never modify or use it.
The group ID gives the bridge driver more control how callbacks are called.
For example, there may be multiple audio chips on a board, each capable of
changing the volume. But usually only one will actually be used when the
user want to change the volume. You can set the group ID for that subdev to
e.g. AUDIO_CONTROLLER and specify that as the group ID value when calling
v4l2_device_call_all(). That ensures that it will only go to the subdev
that needs it.
The advantage of using v4l2_subdev is that it is a generic struct and does
not contain any knowledge about the underlying hardware. So a driver might
contain several subdevs that use an I2C bus, but also a subdev that is
controlled through GPIO pins. This distinction is only relevant when setting
up the device, but once the subdev is registered it is completely transparent.
I2C sub-device drivers
----------------------
Since these drivers are so common, special helper functions are available to
ease the use of these drivers (v4l2-common.h).
The recommended method of adding v4l2_subdev support to an I2C driver is to
embed the v4l2_subdev struct into the state struct that is created for each
I2C device instance. Very simple devices have no state struct and in that case
you can just create a v4l2_subdev directly.
A typical state struct would look like this (where 'chipname' is replaced by
the name of the chip):
struct chipname_state {
struct v4l2_subdev sd;
... /* additional state fields */
};
Initialize the v4l2_subdev struct as follows:
v4l2_i2c_subdev_init(&state->sd, client, subdev_ops);
This function will fill in all the fields of v4l2_subdev and ensure that the
v4l2_subdev and i2c_client both point to one another.
You should also add a helper inline function to go from a v4l2_subdev pointer
to a chipname_state struct:
static inline struct chipname_state *to_state(struct v4l2_subdev *sd)
{
return container_of(sd, struct chipname_state, sd);
}
Use this to go from the v4l2_subdev struct to the i2c_client struct:
struct i2c_client *client = v4l2_get_subdevdata(sd);
And this to go from an i2c_client to a v4l2_subdev struct:
struct v4l2_subdev *sd = i2c_get_clientdata(client);
Finally you need to make a command function to make driver->command()
call the right subdev_ops functions:
static int subdev_command(struct i2c_client *client, unsigned cmd, void *arg)
{
return v4l2_subdev_command(i2c_get_clientdata(client), cmd, arg);
}
If driver->command is never used then you can leave this out. Eventually the
driver->command usage should be removed from v4l.
Make sure to call v4l2_device_unregister_subdev(sd) when the remove() callback
is called. This will unregister the sub-device from the bridge driver. It is
safe to call this even if the sub-device was never registered.
The bridge driver also has some helper functions it can use:
struct v4l2_subdev *sd = v4l2_i2c_new_subdev(adapter, "module_foo", "chipid", 0x36);
This loads the given module (can be NULL if no module needs to be loaded) and
calls i2c_new_device() with the given i2c_adapter and chip/address arguments.
If all goes well, then it registers the subdev with the v4l2_device. It gets
the v4l2_device by calling i2c_get_adapdata(adapter), so you should make sure
that adapdata is set to v4l2_device when you setup the i2c_adapter in your
driver.
You can also use v4l2_i2c_new_probed_subdev() which is very similar to
v4l2_i2c_new_subdev(), except that it has an array of possible I2C addresses
that it should probe. Internally it calls i2c_new_probed_device().
Both functions return NULL if something went wrong.
struct video_device
-------------------
The actual device nodes in the /dev directory are created using the
video_device struct (v4l2-dev.h). This struct can either be allocated
dynamically or embedded in a larger struct.
To allocate it dynamically use:
struct video_device *vdev = video_device_alloc();
if (vdev == NULL)
return -ENOMEM;
vdev->release = video_device_release;
If you embed it in a larger struct, then you must set the release()
callback to your own function:
struct video_device *vdev = &my_vdev->vdev;
vdev->release = my_vdev_release;
The release callback must be set and it is called when the last user
of the video device exits.
The default video_device_release() callback just calls kfree to free the
allocated memory.
You should also set these fields:
- parent: set to the parent device (same device as was used to register
v4l2_device).
- name: set to something descriptive and unique.
- fops: set to the file_operations struct.
- ioctl_ops: if you use the v4l2_ioctl_ops to simplify ioctl maintenance
(highly recommended to use this and it might become compulsory in the
future!), then set this to your v4l2_ioctl_ops struct.
If you use v4l2_ioctl_ops, then you should set .unlocked_ioctl to
__video_ioctl2 or .ioctl to video_ioctl2 in your file_operations struct.
video_device registration
-------------------------
Next you register the video device: this will create the character device
for you.
err = video_register_device(vdev, VFL_TYPE_GRABBER, -1);
if (err) {
video_device_release(vdev); // or kfree(my_vdev);
return err;
}
Which device is registered depends on the type argument. The following
types exist:
VFL_TYPE_GRABBER: videoX for video input/output devices
VFL_TYPE_VBI: vbiX for vertical blank data (i.e. closed captions, teletext)
VFL_TYPE_RADIO: radioX for radio tuners
VFL_TYPE_VTX: vtxX for teletext devices (deprecated, don't use)
The last argument gives you a certain amount of control over the device
kernel number used (i.e. the X in videoX). Normally you will pass -1 to
let the v4l2 framework pick the first free number. But if a driver creates
many devices, then it can be useful to have different video devices in
separate ranges. For example, video capture devices start at 0, video
output devices start at 16.
So you can use the last argument to specify a minimum kernel number and
the v4l2 framework will try to pick the first free number that is equal
or higher to what you passed. If that fails, then it will just pick the
first free number.
Whenever a device node is created some attributes are also created for you.
If you look in /sys/class/video4linux you see the devices. Go into e.g.
video0 and you will see 'name' and 'index' attributes. The 'name' attribute
is the 'name' field of the video_device struct. The 'index' attribute is
a device node index that can be assigned by the driver, or that is calculated
for you.
If you call video_register_device(), then the index is just increased by
1 for each device node you register. The first video device node you register
always starts off with 0.
Alternatively you can call video_register_device_index() which is identical
to video_register_device(), but with an extra index argument. Here you can
pass a specific index value (between 0 and 31) that should be used.
Users can setup udev rules that utilize the index attribute to make fancy
device names (e.g. 'mpegX' for MPEG video capture device nodes).
After the device was successfully registered, then you can use these fields:
- vfl_type: the device type passed to video_register_device.
- minor: the assigned device minor number.
- num: the device kernel number (i.e. the X in videoX).
- index: the device index number (calculated or set explicitly using
video_register_device_index).
If the registration failed, then you need to call video_device_release()
to free the allocated video_device struct, or free your own struct if the
video_device was embedded in it. The vdev->release() callback will never
be called if the registration failed, nor should you ever attempt to
unregister the device if the registration failed.
video_device cleanup
--------------------
When the video device nodes have to be removed, either during the unload
of the driver or because the USB device was disconnected, then you should
unregister them:
video_unregister_device(vdev);
This will remove the device nodes from sysfs (causing udev to remove them
from /dev).
After video_unregister_device() returns no new opens can be done.
However, in the case of USB devices some application might still have one
of these device nodes open. You should block all new accesses to read,
write, poll, etc. except possibly for certain ioctl operations like
queueing buffers.
When the last user of the video device node exits, then the vdev->release()
callback is called and you can do the final cleanup there.
video_device helper functions
-----------------------------
There are a few useful helper functions:
You can set/get driver private data in the video_device struct using:
void *video_get_drvdata(struct video_device *dev);
void video_set_drvdata(struct video_device *dev, void *data);
Note that you can safely call video_set_drvdata() before calling
video_register_device().
And this function:
struct video_device *video_devdata(struct file *file);
returns the video_device belonging to the file struct.
The final helper function combines video_get_drvdata with
video_devdata:
void *video_drvdata(struct file *file);
You can go from a video_device struct to the v4l2_device struct using:
struct v4l2_device *v4l2_dev = dev_get_drvdata(vdev->parent);

Advanced APIs for drivers
-------------------------
A. Exporting pages to users with remap_pfn_range, io_remap_pfn_range,
vm_insert_pfn
Drivers wanting to export some pages to userspace do it by using mmap
interface and a combination of
1) pgprot_noncached()
2) io_remap_pfn_range() or remap_pfn_range() or vm_insert_pfn()
With PAT support, a new API pgprot_writecombine is being added. So, drivers can
continue to use the above sequence, with either pgprot_noncached() or
pgprot_writecombine() in step 1, followed by step 2.
In addition, step 2 internally tracks the region as UC or WC in memtype
list in order to ensure no conflicting mapping.
Note that this set of APIs only works with IO (non RAM) regions. If driver
wants to export a RAM region, it has to do set_memory_uc() or set_memory_wc()
as step 0 above and also track the usage of those pages and use set_memory_wb()
before the page is freed to free pool.
Notes:
-- in the above table mean "Not suggested usage for the API". Some of the --'s
