Due to this assumption and due to the encoded frequency check during initialization, speedstep-centrino driver fails even on systems that has proper ACPI information to do the P-state transition. The change below moves the centrino-speedstep detection to be used only when table based P-state transition is done. For ACPI based P-state transition, we skip the centrino_cpu identification, and as a result we don't use the bus speed assumption in extract_clock. This change makes speedstep-centrino work on Pentium-M based systems, which have more than 100MHz bus speed.

Recent source code inspection revealed that while it worked splendid and to the expectation under normal circumstances, It broke down under unexpected condition where some address calculation might go outside the legal address range the original copy_user was called for. This patch is to make copy_user exception handler more robust and to prevent potential memory corruption.

The BNX2_PCICFG_MISC_STATUS should only be read when the status tag has not changed. Add prefetch of the status block in bnx2_msi() similar to tg3_msi(). The status block is not touched in bnx2_msi() and prefetching it will speed up bnx2_poll() that will run on the same CPU that received the MSI. Update version.

In this new code i see that rt_intern_hash is called before dst->refcnt is set to 1, dst is the 2nd arg to rt_intern_hash. Arg 2 of rt_intern_hash must come with refcnt 1 as it is added to table or dropped depending on error/add/update. One such example is ip_mkroute_input where __mkroute_input return rth with refcnt 0 which is provided to rt_intern_hash. ip_mkroute_output looks like a 2nd such place.

Since GCC has to emit a call and a delay slot to the out-of-line "membar" routines in arch/sparc64/lib/mb.S it is much better to just do the necessary predicted branch inline instead as: ba,pt %xcc, 1f membar #whatever 1: instead of the current: call membar_foo dslot because this way GCC is not required to allocate a stack frame if the function can be a leaf function. This also makes this bug fix easier to backport to 2.4.x Signed-off-by: David S.

The only purpose of this registration is to ensure that the VIO subsystem is notified of new VIO buses during DLPAR adds. Similarly, rpaphp notifies the VIO subsystem when a VIO bus is DLPAR-removed. The rpaphp module has special case code to fake results for attributes like power, adapter status, etc. The VIO register/unregister functions could just as easily be made from the DLPAR module. This patch moves the VIO registration calls to the DLPAR module, and removes the VIO fluff from rpaphp altogether.

This is unnecessary, since the module is actually interested in the subordinate bus of the bridge. The dependency on a PCI bridge device also prohibits the module from registering hotplug slots that have a root bridge as a parent, since root bridges on PPC64 don't have PCI devices. This patch changes struct slot to reference the PCI subsystem using a pci_bus rather than a pci_dev.

As such, the rpaphp has special case code to fake results for attributes like power, adapter status, etc. This patch removes types 2 and 3 from the rpaphp module.

Linville" Date: Wed, 27 Jul 2005 10:19:44 -0400 Subject: [PATCH 067/154] [PATCH] PCI: restore BAR values after D3hot->D0 for devices that need it Some PCI devices (e.g. 3c905B, 3c556B) lose all configuration (including BARs) when transitioning from D3hot->D0. This leaves such a device in an inaccessible state. The patch below causes the BARs to be restored when enabling such a device, so that its driver will be able to access it. The patch also adds pci_restore_bars as a new global symbol, and adds a correpsonding EXPORT_SYMBOL_GPL for that. Some firmware (e.g. Thinkpad T21) leaves devices in D3hot after a (re)boot. Most drivers call pci_enable_device very early, so devices left in D3hot that lose configuration during the D3hot->D0 transition will be inaccessible to their drivers. Drivers could be modified to account for this, but it would be difficult to know which drivers need modification. This is especially true since often many devices are covered by the same driver. It likely would be necessary to replicate code across dozens of drivers. The patch below should trigger only when transitioning from D3hot->D0 (or at boot), and only for devices that have the "no soft reset" bit cleared in the PM control register. I believe it is safe to include this patch as part of the PCI infrastructure. The cleanest implementation of pci_restore_bars was to call pci_update_resource. Unfortunately, that does not currently exist for the sparc64 architecture. The patch below includes a null implemenation of pci_update_resource for sparc64. Some have expressed interest in making general use of the the pci_restore_bars function, so that has been exported to GPL licensed modules. Signed-off-by: John W.

Miller" Date: Mon, 8 Aug 2005 13:19:08 -0700 Subject: [PATCH 068/154] [PATCH] Make sparc64 use setup-res.c There were three changes necessary in order to allow sparc64 to use setup-res.c: 1) Sparc64 roots the PCI I/O and MEM address space using parent resources contained in the PCI controller structure. I'm actually surprised no other platforms do this, especially ones like Alpha and PPC{,64}. These resources get linked into the iomem/ioport tree when PCI controllers are probed. So the hierarchy looks like this: iomem --| PCI controller 1 MEM space --| device 1 device 2 etc. PCI controller 2 MEM space --| ... ioport --| PCI controller 1 IO space --| ... PCI controller 2 IO space --| ... You get the idea. The drivers/pci/setup-res.c code allocates using plain iomem_space and ioport_space as the root, so that wouldn't work with the above setup. So I added a pcibios_select_root() that is used to handle this. It uses the PCI controller struct's io_space and mem_space on sparc64, and io{port,mem}_resource on every other platform to keep current behavior. 2) quirk_io_region() is buggy. It takes in raw BUS view addresses and tries to use them as a PCI resource. pci_claim_resource() expects the resource to be fully formed when it gets called. The sparc64 implementation would do the translation but that's absolutely wrong, because if the same resource gets released then re-claimed we'll adjust things twice. So I fixed up quirk_io_region() to do the proper pcibios_bus_to_resource() conversion before passing it on to pci_claim_resource(). 3) I was mistakedly __init'ing the function methods the PCI controller drivers provide on sparc64 to implement some parts of these routines. This was, of course, easy to fix. So we end up with the following, and that nasty SPARC64 makefile ifdef in drivers/pci/Makefile is finally zapped. Signed-off-by: David S.

This patch adds a function to the PCI core that traverses all the PCI devices on a PCI bus and under any PCI-PCI bridges on that bus (and so on), calling a given function for each device. This provides a way for the error recovery code to iterate through all devices that are affected by an error event. This version is not implemented as a recursive function. Instead, when we reach a PCI-PCI bridge, we set the pointers to start doing the devices on the bus under the bridge, and when we reach the end of a bus's devices, we use the bus->self pointer to go back up to the next higher bus and continue doing its devices.

However these days modern gcc apparently got better at not being influenced by such constructs (which is good in general) and therefore such workaround is of no real advantage anymore. The good news is that gcc (from version 4.1.0) is now fixed with regards to the defficiency this workaround was trying to address. For those interested the patch can easily be backported to older gcc versions and can be found here: http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/gcc/config/arm/arm.c.diff?r1=1.476&r2=1.478 and also here: http://savannah.gnu.org/cgi-bin/viewcvs/gcc/gcc/gcc/config/arm/arm.c.diff?r1=text&tr1=1.476&r2=text&tr2=1.478&diff_format=u Signed-off-by: Nicolas Pitre Signed-off-by: Russell King --- include/asm-arm/arch-pxa/hardware.h | 18 +++--------------- include/asm-arm/arch-sa1100/hardware.h | 18 ++---------------- 2 files changed, 5 insertions(+), 31 deletions(-) diff --git a/include/asm-arm/arch-pxa/hardware.h b/include/asm-arm/arch-pxa/hardware.h index 72b04d846a2..cf35721cfa4 100644 --- a/include/asm-arm/arch-pxa/hardware.h +++ b/include/asm-arm/arch-pxa/hardware.h @@ -44,24 +44,12 @@ #ifndef __ASSEMBLY__ -#if 0 -# define __REG(x) (*((volatile u32 *)io_p2v(x))) -#else -/* - * This __REG() version gives the same results as the one above, except - * that we are fooling gcc somehow so it generates far better and smaller - * assembly code for access to contigous registers.

This won't improve the object code at all, but it does save a lot of repetitive and error-prone source code ... and will simplify the work of supporting a new controller driver, since most new gadget drivers will no longer need patches (unless some hardware quirks limit USB protocol messaging). Added minor cleanups and identifer hooks for the UDC in the Freescale iMX series processors.

A special command sequence is sent to switch it into full bluetooth mode. When this occurs the original HID device vanishes, and a new (bluetooth HID) USB device appears on the bus with a different product ID. The original thread is here: http://sourceforge.net/mailarchive/message.php?msg_id=12532263 The attached patch adds the device to the hid-core quirks so that hid-core ignores it.

Alas, I had to skip some OLS partying, but it was for the good cause. Now the speed of ub is quite acceptable even on partitions with small block size. The ub does not really support S/G. Instead, it just tells the block layer that it does. Then, most of the time, the block layer merges requests and passes single-segmnent requests down to ub; everything works as before. Very rarely ub gets an unmerged S/G request. In such case, it issues several commands to the device. I added a small array of counters to monitor the merging (sg_stat). This may be dropped later.

This is similar to what usb-storage does, only instead of a few URBs allocated together, one URB is reused. Jens's idea was very nice, but it collapsed when I had to support packet commads for CD burning. I cannot issue two or more packet commands where application expected only one. However, burning does not work completely yet. The cdrecord starts, recognizes the device, then aborts without writing a TOC.

It has been rediffed against the latest tree. The SCSI people have deprecated the use of scsi_cmnd.serial_number for anything other than printk. Worse than that, the SCSI core doesn't always increment the number (when the error handler is running, for example). So this patch creates a locally-stored value for use in bulk-only tags. The net result is a simplification, since we no longer have to save & restore the serial_number value while autosensing.

Disconnect processing in usb-storage naturally divides into two parts: one to quiesce the driver (make sure no commands are executing or queued) and remove the host, and the other to deallocate all the USB and non-USB resources. This patch creates two subroutines to handle those two parts. Mostly it's just code movement, but there is one significant change. If the scsi-scanning thread fails to initialize but the host has successfully been added, we need to quiesce the driver before removing the host. After all, it's possible that scanning could have been initiated from somewhere else, such as userspace -- very low probability, but it's easily handled by calling the new subroutine.

If disconnect is called during that window, the driver won't cancel the pending command -- we've been relying on the SCSI core to cancel it for us during host removal. But it's better for usb-storage to cancel it; this avoids races and reduces reliance on the SCSI core. Fortunately cancelling these commands is easy to do; the key is to do it _before_ calling scsi_remove_host.

Please note the order of submission of this latest patch series -- even tho this has an older original number, it is the last patch I'll be sending today. This patch changes the reported SCSI revision level to 2 for all disk-type devices. This is needed in a few cases because the device reports a level of 3 or higher but then crashes when given a REPORT LUNS command (for which support is supposed to be mandatory at those levels). This shouldn't harm us, since it only matters for sparse LUNs and we have separate ways of coping with that.

Mr. Stern explained, "This flag is a relic from an earlier, less-well-designed system. For over a year it hasn't been used for anything other than printing warning messages." An anonymous spokesman for the Linux kernel development community commented, "This is exactly the sort of thing we see happening all the time. As the kernel evolves, support for old techniques and old code can be jettisoned and replaced by newer, better approaches. Proprietary operating systems do not have the freedom or flexibility to change so quickly." Mr. Stern, a staff member at Harvard University's Rowland Institute who works on Linux only as a hobby, noted that the patch (labelled as548) did not update two files, keyspan.c and option.c, in the USB drivers' "serial" subdirectory. "Those files need more extensive changes," he remarked. "They examine the status field of several URBs at times when they're not supposed to. That will need to be fixed before the URB_ASYNC_UNLINK flag is removed." Greg Kroah-Hartman, the kernel maintainer responsible for overseeing all of Linux's USB drivers, did not respond to our inquiries or return our calls. His only comment was "Applied, thanks."

This patch (which has been tested on both flash and cdrom) removes some unnecessary code, moves device detection to much later during initialization, and introduces a new detection routine which appears to work.

Normally this will never happen, but there are a few oddball ways to unbind the hub driver while leaving the children intact. For example, the new "unbind" sysfs attribute can be used for this purpose. Given that unbinding hubs with children is now safe, the patch also removes the code that prevented people from doing so using usbfs.

That driver only binds to USB devices, as opposed to interfaces, and it does nothing much besides marking which struct device's go with an overall USB device plus providing suspend/resume methods. Now that users can unbind drivers at will using the sysfs "unbind" attribute, we need a rational way of dealing with USB devices that are no longer under full control of the USB stack.

This one handles only the very simplest hardware, which can be handled almost entirely by the "usbnet" core. - Move device-specific bits into new "cdc_subset.c" driver, shrinking "usbnet" by a bunch; - Export the functions needed to support this minidriver (with EXPORT_SYMBOL_GPL); - Update Kconfig and kbuild accordingly. This one handles about a dozen different device types, with the most notable ones being Gumstix and most Linux-based PDAs (except Zaurus running that ancient code from Sharp).

* Force alignment at key spots when using ax88772 framing (on some embedded hardware, the network stack will break otherwise); * Address some link reset problems. It also makes this driver use the standard (5 seconds vs half second) control timeouts used elsewhere in USB; and wraps a few lines before the 80th column (which previously needed it).

From 904813cd8a0b334189da285bb05af0b18b062502 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Wed, 31 Aug 2005 09:53:26 -0700 Subject: [PATCH 127/154] [PATCH] USB: usbnet (4/9) module for net1080 cables As with the "cdc_subset" and "asix" drivers, this just moves the net1080 support into its one driver module. In this case there's a small bit of extra cleanup involved, moving some funky framing logic into the tx_fixup() routine (resolving a long overdue FIXME). Minor historical note: "usbnet" started out as "net1080", then got generalized to make it easier for other network drivers to reuse the urb queueing and fault management code here.

It also fixes a "return wrong skb" glitch in the rx unbatching, as recently reported, and adds some missing byteswaps in the special "genelink" headers (so it might now work on big-endian Linux).

This module is a bit special since it exports utility functions that are reused by the the Zaurus and RNDIS drivers, but it's not "core" like usbnet itself.

Tested with little-endian Linux talking to a Linux-USB Ethernet/RNDIS based peripheral. This also includes updates from Eddie C. Dost for big-endian SPARC Linux talking to a Nokia 9500 Communicator. It's still marked as EXPERIMENTAL because this code is so young. This ought to let Linux to work with various cable modems that previously would have been "Windows Only".

It also includes some minor cleanups to the remaining "usbnet" file, notably removing that long changelog at the top. Minor historical note: Linux 2.2 first called the driver for this hardware "plusb".
