Users: joachim.deguara@amd.com
|
||||
These files exist in every CPU's cache/index3 directory. Each
|
||||
cache_disable_{0,1} file corresponds to one disable slot which
|
||||
can be used to disable a cache index. Reading from these files
|
||||
on a processor with this functionality will return the currently
|
||||
disabled index for that node. There is one L3 structure per
|
||||
node, or per internal node on MCM machines. Writing a valid
|
||||
index to one of these files will cause the specificed cache
|
||||
index to be disabled.
|
||||
|
||||
All AMD processors with L3 caches provide this functionality.

Description:
|

Some servers used internally at Google have firmware
|
||||
that provides callback functionality via explicit SMI
|
||||
triggers. Some of the callbacks are similar to those
|
||||
provided by the EFI runtime services page, but due to
|

historical reasons this different entry-point has been
|
||||
used.
|
||||
|
||||
The gsmi driver implements the kernel's abstraction for
|
||||
these firmware callbacks. Currently, this functionality
|
||||
is limited to handling the system event log and getting
|
||||
access to EFI-style variables stored in nvram.

the system eventlog. The binary format is

interpreted by the firmware and may change from

platform to platform. The only kernel-enforced
|

requirement is that the blob be prefixed with a

clear. Not all platforms support fractional
|

clearing though, and this writes to this file

will error out if the firmware doesn't like your

"W" The kernel thread is waiting because there is no work

its designated CPU.

The output of "cat rcu/rcuboost" looks as follows:

||||
|
||||
0:5 tasks=.... kt=W ntb=0 neb=0 nnb=0 j=2f95 bt=300f

|
||||
|
||||
This information is output only for rcu_preempt. Each two-line entry
|
||||
corresponds to a leaf rcu_node strcuture. The fields are as follows:
|
||||
|
||||
o "n:m" is the CPU-number range for the corresponding two-line
|
||||
entry. In the sample output above, the first entry covers
|
||||
CPUs zero through five and the second entry covers CPUs 6
|
||||
and 7.
|
||||
|
||||
o "tasks=TNEB" gives the state of the various segments of the
|
||||
rnp->blocked_tasks list:
|
||||
|
||||
"T" This indicates that there are some tasks that blocked
|
||||
while running on one of the corresponding CPUs while
|
||||
in an RCU read-side critical section.
|
||||
|
||||
"N" This indicates that some of the blocked tasks are preventing
|
||||
the current normal (non-expedited) grace period from
|
||||
completing.
|
||||
|
||||
"E" This indicates that some of the blocked tasks are preventing
|
||||
the current expedited grace period from completing.
|
||||
|
||||
"B" This indicates that some of the blocked tasks are in
|
||||
need of RCU priority boosting.
|
||||
|
||||
Each character is replaced with "." if the corresponding
|
||||
condition does not hold.
|
||||
|
||||
o "kt" is the state of the RCU priority-boosting kernel
|
||||
thread associated with the corresponding rcu_node structure.
|
||||
The state can be one of the following:
|
||||
|
||||
"S" The kernel thread is stopped, in other words, all
|
||||
CPUs corresponding to this rcu_node structure are
|
||||
offline.
|
||||
|
||||
"R" The kernel thread is running.
|
||||
|
||||
"W" The kernel thread is waiting because there is no work
|
||||
for it to do.
|
||||
|
||||
"Y" The kernel thread is yielding to avoid hogging CPU.
|
||||
|
||||
"?" Unknown value, indicates a bug.
|
||||
|
||||
o "ntb" is the number of tasks boosted.
|
||||
|
||||
o "neb" is the number of tasks boosted in order to complete an
|
||||
expedited grace period.
|
||||
|
||||
o "nnb" is the number of tasks boosted in order to complete a
|
||||
normal (non-expedited) grace period. When boosting a task
|
||||
that was blocking both an expedited and a normal grace period,
|
||||
it is counted against the expedited total above.
|
||||
|
||||
o "j" is the low-order 16 bits of the jiffies counter in
|
||||
hexadecimal.
|
||||
|
||||
o "bt" is the low-order 16 bits of the value that the jiffies
|
||||
counter will have when we next start boosting, assuming that
|
||||
the current grace period does not end beforehand. This is
|
||||
also in hexadecimal.
|
||||
|
||||
o "balk: nt" counts the number of times we didn't boost (in
|
||||
other words, we balked) even though it was time to boost because
|
||||
there were no blocked tasks to boost. This situation occurs
|
||||
when there is one blocked task on one rcu_node structure and
|
||||
none on some other rcu_node structure.
|
||||
|
||||
o "egt" counts the number of times we balked because although
|
||||
there were blocked tasks, none of them were blocking the
|
||||
current grace period, whether expedited or otherwise.
|
||||
|
||||
o "bt" counts the number of times we balked because boosting
|
||||
had already been initiated for the current grace period.
|
||||
|
||||
o "nb" counts the number of times we balked because there
|
||||
was at least one task blocking the current non-expedited grace
|
||||
period that never had blocked. If it is already running, it
|
||||
just won't help to boost its priority!
|
||||
|
||||
o "ny" counts the number of times we balked because it was
|
||||
not yet time to start boosting.
|
||||
|
||||
o "nos" counts the number of times we balked for other
|
||||
reasons, e.g., the grace period ended first.

Fields
|
||||
~~~~~~
|
||||
g_list: Node in the global device list.
|
||||
|
||||
node: Node in device's parent's children list.
|
||||
|
||||
bus_list: Node in device's bus's devices list.
|
||||
|
||||
driver_list: Node in device's driver's devices list.
|
||||
|
||||
intf_list: List of intf_data. There is one structure allocated for
|
||||
each interface that the device supports.
|
||||
|
||||
children: List of child devices.
|
||||
|
||||
parent: *** FIXME ***
|
||||
|
||||
name: ASCII description of device.
|
||||
Example: " 3Com Corporation 3c905 100BaseTX [Boomerang]"
|
||||
|
||||
bus_id: ASCII representation of device's bus position. This
|
||||
field should be a name unique across all devices on the
|
||||
bus type the device belongs to.
|
||||
|
||||
Example: PCI bus_ids are in the form of
|
||||
<bus number>:<slot number>.<function number>
|
||||
This name is unique across all PCI devices in the system.
|
||||
|
||||
lock: Spinlock for the device.
|
||||
|
||||
refcount: Reference count on the device.
|
||||
|
||||
bus: Pointer to struct bus_type that device belongs to.
|
||||
|
||||
dir: Device's sysfs directory.
|
||||
|
||||
class_num: Class-enumerated value of the device.
|
||||
|
||||
driver: Pointer to struct device_driver that controls the device.
|
||||
|
||||
driver_data: Driver-specific data.
|
||||
|
||||
platform_data: Platform data specific to the device.
|
||||
|
||||
Example: for devices on custom boards, as typical of embedded
|
||||
and SOC based hardware, Linux often uses platform_data to point
|
||||
to board-specific structures describing devices and how they
|
||||
are wired. That can include what ports are available, chip
|
||||
variants, which GPIO pins act in what additional roles, and so
|
||||
on. This shrinks the "Board Support Packages" (BSPs) and
|
||||
minimizes board-specific #ifdefs in drivers.
|
||||
|
||||
current_state: Current power state of the device.
|
||||
|
||||
saved_state: Pointer to saved state of the device. This is usable by
|
||||
the device driver controlling the device.
|
||||
|
||||
release: Callback to free the device after all references have
|
||||
gone away. This should be set by the allocator of the
|
||||
device (i.e. the bus driver that discovered the device).

||||

Suspend notifiers

|

There are some operations that device drivers may want to carry out in their
|
||||
.suspend() routines, but shouldn't, because they can cause the hibernation or
|
||||
suspend to fail. For example, a driver may want to allocate a substantial amount
|
||||
of memory (like 50 MB) in .suspend(), but that shouldn't be done after the
|
||||
swsusp's memory shrinker has run.
|
||||
There are some operations that subsystems or drivers may want to carry out
|
||||
before hibernation/suspend or after restore/resume, but they require the system
|
||||
to be fully functional, so the drivers' and subsystems' .suspend() and .resume()
|
||||
or even .prepare() and .complete() callbacks are not suitable for this purpose.
|
||||
For example, device drivers may want to upload firmware to their devices after
|
||||
resume/restore, but they cannot do it by calling request_firmware() from their
|
||||
.resume() or .complete() routines (user land processes are frozen at these
|
||||
points). The solution may be to load the firmware into memory before processes
|
||||
are frozen and upload it from there in the .resume() routine.
|
||||
A suspend/hibernation notifier may be used for this purpose.
|
||||
|
||||
Also, there may be some operations, that subsystems want to carry out before a
|
||||
hibernation/suspend or after a restore/resume, requiring the system to be fully
|
||||
functional, so the drivers' .suspend() and .resume() routines are not suitable
|
||||
for this purpose. For example, device drivers may want to upload firmware to
|
||||
their devices after a restore from a hibernation image, but they cannot do it by
|
||||
calling request_firmware() from their .resume() routines (user land processes
|
||||
are frozen at this point). The solution may be to load the firmware into
|
||||
memory before processes are frozen and upload it from there in the .resume()
|
||||
routine. Of course, a hibernation notifier may be used for this purpose.
