* [PATCH] PCI: nVidia quirk to make AER PCI-E extended capability visibleBrice Goglin2006-06-21
| | | | | | | | | | | | | | The nVidia CK804 PCI-E chipset supports the AER extended capability but sometimes fails to link it (with some BIOS or after a warm reboot). It makes the AER cap invisible to pci_find_ext_capability(). The patch adds a quirk to set the missing bit that controls the linking of the capability. By the way, it removes the corresponding code in the myri10ge driver.

* [PATCH] PCI: Bus Parity Status sysfs interfaceDoug Thompson2006-06-21
| | | | | | | | | | | | | | | From: Doug Thompson <norsk5@yahoo.com> This patch adds the 'broken_parity_status' sysfs attribute file to a PCI device. Reading this attribute a userland program can determine if PCI device provides false positives (value of 1) in its generation of PCI Parity status, or not (value of 0). As PCI devices are found to be 'bad' in this regard, userland programs can also set the appropriate value (root access only) of a faulty device. This per device information will be used in the EDAC PCI Parity scanner code in a future patch once this interface becomes available.

* [PATCH] PCI: don't move ioapics below PCI bridgeKimball Murray2006-06-21
| | | | | | | | | | | | | | | | | A recent Stratus x86_64 platform uses a system ioapic that is a PCI device located below a PCI bridge. Other platforms like this may exist. This patch fixes a problem wherein the kernel's PCI setup code moves the ioapic to an address other than that assigned by the BIOS. It simply adds another exclusion (which already includes classless devices and host bridges) to the function pbus_assign_resources_sorted so that it will not move the ioapic. If the ioapic is moved, the fixmap mapping to it is broken, so the OS should leave it alone. From: Kimball Murray <kimball.murray@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] PCI: disable msi mode in pci_disable_deviceShaohua Li2006-06-21
| | | | | | | | | | | | | | | Brice said the pci_save_msi_state breaks his driver in his special usage (not in suspend/resume), as pci_save_msi_state will disable msi mode. In his usage, pci_save_state will be called at runtime, and later (after the device operates for some time and has an error) pci_restore_state will be called. In another hand, suspend/resume needs disable msi mode, as device should stop working completely. This patch try to workaround this issue. Drivers are expected call pci_disable_device in suspend time after pci_save_state. Signed-off-by: Shaohua Li <shaohua.li@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] PCI: Allow MSI to work on kexec kernelRajesh Shah2006-06-21
| | | | | | | | | | | | | | | We recently ran into a problem where the e1000 device failed to work properly on the kexec kernel. MSI was enabled for the device in the main kernel when it crashed. The e1000 driver tried to enable MSI on the kexec kernel, but the code bailed early when it found that MSI was already enabled in the hardware, even though the software state was not properly set up in the kexec'd kernel. This patch fixes the problem by moving the early return to after making sure that the software state is properly initialized.

* [PATCH] PCI Bus Parity Status-broken hardware attribute, EDAC foundationDoug Thompson2006-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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.

* [PATCH] PCI: fix to pci ignore pre-set 64-bit bars on 32-bit platformsBjorn Helgaas2006-06-21
| | | | | | | | | | | | | | | | | | 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.

* [PATCH] PCI: Ignore pre-set 64-bit BARs on 32-bit platformsH. Peter Anvin2006-06-21
| | | | | | | | | | | | | | | | | | | [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>

| * [PATCH] pciehp: Fix programming hotplug parametersKenji Kaneshige2006-06-19
| | | | | | | | | | | | | | | | | | | | | | Current PCHEHP driver doesn't have any code to program hotplug parameters from firmware. So hotplug parameters are never programed at hot-add time. This patch add support for programming hotplug parameters to PCIEHP driver.

| * [PATCH] acpi_pcihp: Remove improper error message about OSHPKenji Kaneshige2006-06-19
| | | | | | | | | | | | | | | | | | | | | | | | This patch converts the improper error message about OSHP evaluation to debug message which is displayed only when pci_hotplug.ko is loaded with debugging mode enabled. To do this, this patch adds a new module parameter "debug_acpi" to pci_hotplug.ko for enabling/disabling debug messages in acpi_pcihp.c.

| * [PATCH] acpi_pcihp: Fix programming _HPP valuesKenji Kaneshige2006-06-19
| | | | | | | | | | | | | | | | | | | | | | This patch fixes the problem that hotplug parameters are not programed when PCI cards are hot-added by ACPIPHP, SHPCHP and PCIEHP driver. The pci_dev structure being hot-added is not bound to ACPI handle, so we need to trace PCI bus tree to find ACPI handle.

| * [PATCH] acpiphp: turn off slot power at error caseMUNEDA Takahiro2006-06-19
| | | | | | | | | | | | | | | | | | | | | | | | When acpiphp_enable_slot() is failed, acpiphp does not change the slot->flags. Therefore, when user tries to read power status, acpiphp_get_power_status() returns the enable status whether the slot is not really enabled. This patch fixes this BUG.
