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.

Prakash reported that his c51-mcp51 ondie sound card doesn't work with MSI. But if he hacks out the HT-MSI quirk, MSI works fine. So this patch reworks the nv_msi_ht_cap_quirk().

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).

2008-07-18x86, pci: introduce config option for pci reroute quirks (was: [PATCH 0/3] ↵Stefan Assmann
Boot IRQ quirks for Broadcom and AMD/ATI) This is against linux-2.6-tip, branch pci-ioapic-boot-irq-quirks. From: Stefan Assmann <sassmann@suse.de> Subject: Introduce config option for pci reroute quirks The config option X86_REROUTE_FOR_BROKEN_BOOT_IRQS is introduced to enable (or disable) the redirection of the interrupt handler to the boot interrupt line by default. Depending on the existence of interrupt masking / threaded interrupt handling in the kernel (vanilla, rt, ...) and the maturity of the rerouting patch, users can enable or disable the redirection by default. This means that the reroute quirk can be applied to any kernel without changing it. Interrupt sharing could be increased if this option is enabled. However this option is vital for threaded interrupt handling, as done by the RT kernel. It should simplify the consolidation with the RT kernel. The option can be overridden by either pci=ioapicreroute or pci=noioapicreroute.

2008-07-08pci, acpi: reroute PCI interrupt to legacy boot interrupt equivalentStefan Assmann
Some chipsets (e.g. intel 6700PXH) generate a legacy INTx when the IRQ entry in the chipset's IO-APIC is masked (as, e.g. the RT kernel does during interrupt handling). On chipsets where this INTx generation cannot be disabled, we reroute the valid interrupts to their legacy equivalent to get rid of spurious interrupts that might otherwise bring down (vital) interrupt lines through spurious interrupt detection in note_interrupt(). This patch benefited from discussions with Alexander Graf, Torsten Duwe, Ihno Krumreich, Daniel Gollub, Hannes Reinecke.

2008-07-02PCI: Limit VPD read/write lengths for Broadcom 5706, 5708, 5709 rev.Benjamin Li
For Broadcom 5706, 5708, 5709 rev. A nics, any read beyond the VPD end tag will hang the device. This problem was initially observed when a vpd entry was created in sysfs ('/sys/bus/pci/devices/<id>/vpd'). A read to this sysfs entry will dump 32k of data. Reading a full 32k will cause an access beyond the VPD end tag causing the device to hang. Once the device is hung, the bnx2 driver will not be able to reset the device. We believe that it is legal to read beyond the end tag and therefore the solution is to limit the read/write length. A majority of this patch is from Matthew Wilcox who gave code for reworking the PCI vpd size information. A PCI quirk added for the Broadcom NIC's to limit the read/write's.

2008-02-01PCI: modify SB700 SATA MSI quirkShane Huang
SB700 SATA MSI bug will be fixed in SB700 revision A21 at hardware level, but the SB700 revision older than A21 will also be found in the market. This patch modify the original quirk commit bc38b411fe696fad32b261f492cb4afbf1835256 instead of withdrawing it. The patch also removes quirk to 0x4395 because 0x4395 is SB800 device ID.

2008-02-01PCI: use dev_printk in quirk messagesbjorn.helgaas@hp.com
Convert quirk printks to dev_printk(). I made the MSI disable messages a little more consistent: - always use "disabled", not "deactivated" - specify "device MSI disabled" or "subordinate MSI disabled" when disabling MSI for only a specific device or subordinate bus Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-02-01PCI: print quirk name in debug messagesbjorn.helgaas@hp.com
Instead of printing this: PCI: Calling quirk c023b250 for 0000:00:00.0 we can print this: pci 0000:00:00.0: calling quirk 0xc023b270: quirk_cardbus_legacy+0x0/0x30() The address is superfluous because sprint_symbol() includes the address if the symbol lookup fails, but this is the same style used in do_initcalls() and pnp_fixup_device().

2008-02-01PCI: fix for quirk_e100_interrupt()Ivan Kokshaysky
Check that the e100 is in the D0 power state. If it's not, it won't respond to MMIO accesses and we end up with master-abort machine checks on some platforms.
