2006-06-21[PATCH] PCI Bus Parity Status-broken hardware attribute, EDAC foundationDoug Thompson
Currently, the EDAC (error detection and correction) modules that are in the kernel contain some features that need to be moved. After some good feedback on the PCI Parity detection code and interface (http://www.ussg.iu.edu/hypermail/linux/kernel/0603.1/0897.html) this patch ADDs an new attribute to the pci_dev structure: Namely the 'broken_parity_status' bit. When set this indicates that the respective hardware generates false positives of Parity errors. The EDAC "blacklist" solution was inferior and will be removed in a future patch. Also in this patch is a PCI quirk.c entry for an Infiniband PCI-X card which generates false positive parity errors. I am requesting comments on this AND on the possibility of a exposing this 'broken_parity_status' bit to userland via the PCI device sysfs directory for devices. This access would allow for enabling of this feature on new devices and for old devices that have their drivers updated. (SLES 9 SP3 did this on an ATI motherboard video device). There is a need to update such a PCI attribute between kernel releases. This patch just adds a storage place for the attribute and a quirk entry for a known bad PCI device. PCI Parity reaper/harvestor operations are in EDAC itself and will be refactored to use this PCI attribute instead of its own mechanisms (which are currently disabled) in the future.

2006-06-21[PATCH] PCI: Add a "enable" sysfs attribute to the pci devices to allow ↵Arjan van de Ven
userspace (Xorg) to enable devices without doing foul direct access This patch adds an "enable" sysfs attribute to each PCI device. When read it shows the "enabled-ness" of the device, but you can write a "0" into it to disable a device, and a "1" to enable it. This later is needed for X and other cases where userspace wants to enable the BARs on a device (typical example: to run the video bios on a secundary head). Right now X does all this "by hand" via bitbanging, that's just evil. This allows X to no longer do that but to just let the kernel do this.

2006-06-21[PATCH] PCI: Add pci_assign_resource_fixed -- allow fixed address assignmentsKumar Gala
PCI: Add pci_assign_resource_fixed -- allow fixed address assignments On some embedded systems the PCI address for hotplug devices are not only known a priori but are required to be at a given PCI address for other master in the system to be able to access. An example of such a system would be an FPGA which is setup from user space after the system has booted. The FPGA may be access by DSPs in the system and those DSPs expect the FPGA at a fixed PCI address. Added pci_assign_resource_fixed() as a way to allow assignment of the PCI devices's BARs at fixed PCI addresses.

2006-06-21[PATCH] PCI: fix to pci ignore pre-set 64-bit bars on 32-bit platformsBjorn Helgaas
When we detect a 64-bit pre-set address in a BAR on a 32-bit platform, we disable it and treat it as if it had been unset, thus allowing the general address assignment code to assign a new address to it when the device is enabled. This can happen either if the firmware assigns 64-bit addresses; additionally, some cards have been found "in the wild" which do not come out of reset with all the BAR registers set to zero. Unfortunately, the patch that implemented this tested the low part of the address instead of the high part of the address. This patch fixes that.

2006-06-21[PATCH] PCI: Ignore pre-set 64-bit BARs on 32-bit platformsH. Peter Anvin
[pci] Ignore pre-set 64-bit BARs on 32-bit platforms Currently, Linux always rejects a device which has a pre-set 64-bit address on a 32-bit platform. On systems which do not do PCI initialization in firmware, this causes some devices which don't correctly power up with all BARs zero to fail. This patch makes the kernel automatically zero out such an address (thus treating it as if it had not been set at all, meaning it will assign an address if necessary). I have done this only for devices, not bridges. It seems potentially hazardous to do for bridges. Signed-off-by: H. Peter Anvin <hpa@c2micro.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-05-21[PATCH] pci: correctly allocate return buffers for osc callsKristen Accardi
The OSC set and query functions do not allocate enough space for return values, and set the output buffer length to a false, too large value. This causes the acpi-ca code to assume that the output buffer is larger than it actually is, and overwrite memory when copying acpi return buffers into this caller provided buffer. In some cases this can cause kernel oops if the memory that is overwritten is a pointer. This patch will change these calls to use a dynamically allocated output buffer, thus allowing the acpi-ca code to decide how much space is needed.

2006-05-15[PATCH] VIA quirk fixup, additional PCI IDsChris Wedgwood
An earlier commit (75cf7456dd87335f574dcd53c4ae616a2ad71a11) changed an overly-zealous PCI quirk to only poke those VIA devices that need it. However, some PCI devices were not included in what I hope is now the full list. Consequently we're failing to run the quirk on all machines which need it, causing IRQ routing failures. This should I hope correct this. Thanks to Masoud Sharbiani <masouds@masoud.ir> for pointing this out and testing the fix.

2006-04-27[PATCH] PCI quirk: VIA IRQ fixup should only run for VIA southbridgesChris Wedgwood
Alan Cox pointed out that the VIA 'IRQ fixup' was erroneously running on my system which has no VIA southbridge (but I do have a VIA IEEE 1394 device). This should address that. I also changed "Via IRQ" to "VIA IRQ" (initially I read Via as a capitalized via (by way/means of).
