Various PCI bus errors can be signaled by newer PCI controllers. Recovering from those errors requires an infrastructure to notify affected device drivers of the error, and a way of walking through a reset sequence. This patch adds documentation describing the current error recovery proposal. Signed-off-by:

Recovering from those errors requires an infrastructure to notify affected device drivers of the error, and a way of walking through a reset sequence. This patch adds a set of callbacks to be used by error recovery routines to notify device drivers of the various stages of recovery. Signed-off-by:

I upgraded my Toshiba Satellite BIOS recently to see if it would fix an ACPI related problem I have (http://bugzilla.kernel.org/show_bug.cgi?id=5727). Unfortunately, it didn't, and moreover, Toshiba chose to change the system version in the DMI table with the update, causing the OHCI1394 related quirk to break. This patch updates the DMI table for the quirk to include Toshiba's new version name for this machine; I've tested it and it seems to work fine. Signed-off-by:

This patch contains the following cleanups: - hotplug/pciehp_core.c: make the needlessly global hpdriver_context static - #if 0 the following unused functions: - pci.c: pci_bus_max_busnr() - pci.c: pci_max_busnr() - proc.c: pci_proc_attach_bus() - remove.c: pci_remove_device_safe Signed-off-by:Adrian Bunk <bunk@stusta.de> Signed-off-by:

The Compaq PCI Hotplug driver was creating 2 sysfs files that contained nothing but debug information, and had way more than "one value" in them. This patch converts the code to use debugfs for these files instead. Compile tested only. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: -

Here's a small patch to reduce the nr. of pointer dereferences in drivers/pci/hotplug/pciehp_core.c Benefits: - micro speed optimization due to fewer pointer derefs - generated code is slightly smaller - small line length cleanup - better readability Signed-off-by:

idr gently pointed out today that not only is the sysfs rom file interface somewhat unintuitive (despite my efforts and initial implementation), but it's also undocumented! This patch to Documentation/filesystems/sysfs-pci.txt corrects the latter problem; the former is a userland ABI now though, so we're stuck with it for awhile at least. Signed-off-by:

The powerpc PCI code sets up the PCI tree without doing config space accesses in most cases, from the firmware tree. However, it still wants to call pci_cfg_space_size() under some conditions, thus it needs to be made non-static (though I don't see a point to export it to modules). Signed-off-by:

Add a warning if a child bus may be inaccessible because the parent bridge has wrong secondary or subordinate bus numbers. Note that this may or may not happen on "transparent" bridges, as can be seen in bug #5557. Also, if we do not fix up the assignment of bus numbers, try to make use of the bus number space available.

This patch disables power fault, MRL sensor and presence detection interrupts when a PCIe slot is powered-off and enables those interrupts when it is powered-on again. This is necessary to prevent the associated events from causing an endless cycle of interrupts due to the power-fault bit, which stays set till power is restored to the slot. Signed-off-by:

I've implemented a quirk to take advantage of the 1KB I/O space granularity option on the Intel P64H2 PCI Bridge. I had to change probe.c because it sets the resource start and end to be aligned on 4k boundaries (after the quirk sets them to 1k boundaries). I've tested this patch on a Unisys ES7000-600 both with and without the 1KB option enabled. I also tested this on a 2 processor Dell box that doesn't have a P64H2 to make sure there were no negative affects there. Signed-off-by:

The RPAPHP code contains two routines that appear to be gratuitous copies of very similar pci code. In particular, rpaphp_claim_resource ~~ pci_claim_resource (there is a minor, non-functional difference) rpadlpar_claim_one_bus == pcibios_claim_one_bus (the code is identical) This patch removes the rpaphp versions of the code.

Current SHPCHP driver uses msleep_interruptible() function to wait for a command completion event. But I think this would cause an unnecessary long wait until timeout, if command completion interrupt came before task state was changed to TASK_INTERRUPTIBLE. This patch fixes this issue. With this patch, command completion becomes faster as follows: o Without this patch # time echo 1 > power real 0m4.708s user 0m0.000s sys 0m0.524s o With this patch # time echo 1 > power real 0m2.221s user 0m0.000s sys 0m0.532s Signed-off-by:

Current SHPCHP driver writes a '0' to the Command Completion Detect bit to clear the Command Complete Interrupt Pending. But according to the SHPC spec (See 4.7.3.1 System Interrupts), SHPCHP driver must write '1'. This patch fixes this bug. Signed-off-by:

The hpc_get_mode1_ECC_cap() function of SHPCHP driver seems to refer the wrong bit for refering the "Mode 1 ECC Capability" bit. This bug seems not to cause any problem so far. But I think this should be fixed. This patch fixes this bug. Signed-off-by:
