2009-10-12Run pci_apply_final_quirks() sooner.David Woodhouse
Having this as a device_initcall() means that some real device drivers can actually initialise _before_ the quirks are run, which is wrong. We want it to run _before_ device_initcall(), but _after_ fs_initcall(), since some arch-specific PCI initialisation like pcibios_assign_resources() is done at fs_initcall(). We could use rootfs_initcall() but I actually want to use that for the IOMMU initialisation, which has to come after the quirks, but still before the real devices. So use fs_initcall_sync() instead -- since this is entirely synchronous, it doesn't hurt that it'll escape the synchronisation. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

2009-09-09PCI: Simplify hotplug mch quirk.Eric W. Biederman
There is a very old quirk for the intel E7502 E7320 and E7525 memory controller hubs that disables usage of msi interrupts on pcie hotplug bridges of those devices, and disables changing the affinity of irqs. Today all we have to do to disable msi on a specific device is to set dev->no_msi, which is much more straightforward than the previous logic. The re-running of this fixup after pci hotplug happens below these devices is totally bogus. All of the state we change is pure software state and we don't change the hardware at all. Which means hotplug on the lower devices doesn't have a chance to change this state. So we can safely remove the special case from the pciehp driver and the pcie portdriver. I suspect the special case was someone's expermental debug code that slipped in. Certainly it isn't mentioned in commit 6fb8880a61510295aece04a542767161f624dffe aka BKrev: 41966101LJ_ogfOU0m2aE6teZfQnuQ where the code first appears.

2009-06-29PCI: More PATA quirks for not entering D3Alan Cox
The ALi loses some state if it goes into D3. Unfortunately even with the chipset documents I can't figure out how to restore some bits of it. The VIA one saves/restores apparently fine but the ACPI _GTM methods break on some platforms if we do this and this causes cable misdetections. These are both effectively regressions as historically nothing matched the devices and then decided not to bind to them. Nowdays something is binding to all sorts of devices and a result they get dumped into D3.

Some BIOSes hide 'overflow' device (dev #6) for i82875P/PE chipsets. The same happens for i82865P/PE. Add a quirk to enable this device. This allows i82875 EDAC driver to bind to chipset's dev #6 and not dev #0 as the latter is used by AGP driver. On my laptop (i82865P based) ACPI code is disabling this device again in \_SB.PCI0._CRS method (called at least at PNP init time). This can be easily worked around by patching DSDT.

2009-03-20PCI: allow assignment of memory resources with a specified alignmentYuji Shimada
This patch allows memory resources to be assigned with a specified alignment at boot-time or run-time. The patch is useful when we use PCI pass-through, because page-aligned memory resources are required to securely share PCI resources with guest drivers. If you want to assign the resource at boot time, please set "pci=resource_alignment=" boot parameter. This is format of "pci=resource_alignment=" boot parameter: [<order of align>@][<domain>:]<bus>:<slot>.<func>[; ...] Specifies alignment and device to reassign aligned memory resources. If <order of align> is not specified, PAGE_SIZE is used as alignment. PCI-PCI bridge can be specified, if resource windows need to be expanded. This is example: pci=resource_alignment=20@07:00.0;18@0f:00.0;00:1d.7 If you want to assign the resource at run-time, please set "/sys/bus/pci/resource_alignment" file, and hot-remove the device and hot-add the device. For this purpose, fakephp or PCI hotplug interfaces can be used. The format of "/sys/bus/pci/resource_alignment" file is the same with boot parameter. You can use "," instead of ";". For example: # cd /sys/bus/pci # echo -n 20@12:00.0 > resource_alignment # echo 1 > devices/0000:12:00.0/remove # echo 1 > rescan Reviewed-by: Alex Chiang <achiang@hp.com> Reviewed-by: Yu Zhao <yu.zhao@intel.com> Signed-off-by: Yuji Shimada <shimada-yxb@necst.nec.co.jp> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2009-03-12PCI: Add PCI quirk to disable L0s ASPM state for 82575 and 82598Alexander Duyck
This patch is intended to disable L0s ASPM link state for 82598 (ixgbe) parts due to the fact that it is possible to corrupt TX data when coming back out of L0s on some systems. The workaround had been added for 82575 (igb) previously, but did not use the ASPM api. This quirk uses the ASPM api to prevent the ASPM subsystem from re-enabling the L0s state. Instead of adding the fix in igb to the ixgbe driver as well it was decided to move it into a pci quirk. It is necessary to move the fix out of the driver and into a pci quirk in order to prevent the issue from occuring prior to driver load to handle the possibility of the device being passed to a VM via direct assignment.

2009-01-07PCI: extend on the ICH motherboard IO decode quirk listLinus Torvalds
This adds more LPC controller IO range decode quirks for the Intel ICH family of chipsets. They differ a bit between the older ICH6 chipset and the more modern layout of the ICH7-ICH10 chipsets. This patch just prints out the IO decode information found by the quirks, but eventually we may want to add them to the resource tree, in order to know to avoid allocating things over them. That's especially true if it turns out that any firmware ends up putting the magic motherboard resources in an address range that we use for dynamic allocations (ie above PCIBIOS_MIN_IO, which is 0x1000 on x86).
