6397c75cbc MSI: Blacklist PCI-E chipsets depending on Hypertransport MSI capability
Introduce msi_ht_cap_enabled() to check the MSI capability in the
Hypertransport configuration space.
It is used in a generic quirk quirk_msi_ht_cap() to check whether
MSI is enabled on hypertransport chipset, and a nVidia specific quirk
quirk_nvidia_ck804_msi_ht_cap() where two 2 HT MSI mappings have to
be checked.
Both quirks set the PCI_BUS_FLAGS_NO_MSI bus flag when MSI is disabled.

1ae4f9ba84 USB: Add VIA quirk fixup for VT8235 usb2
Patch to add VIA PCI quirk for Enhanced/Extended USB on VT8235
southbridge. It is needed in order to use EHCI/USB 2.0 with ACPI.
Without it IRQs are not routed correctly, you get an "Unlink after
no-IRQ?" error and the device is unusable.

I belive this could also be a fix for Bugzilla Bug 5835.

65ae4dddbb [PATCH] PCI: fix ICH6 quirks
- add the ICH6(R) LPC to the ICH6 ACPI quirks.  currently only the ICH6-M
  is handled.  [ PCI_DEVICE_ID_INTEL_ICH6_1 is the ICH6-M LPC, ICH6_0 is
  the ICH6(R) ]

- remove the wrong quirk calling asus_hides_smbus_lpc() for ICH6.  the
  register modified in asus_hides_smbus_lpc() has a different meaning in
  ICH6.

ffadcc2ff4 [PATCH] PCI: PCIE power management quirk
When changing power states from D0->DX and then from DX->D0, some
Intel PCIE chipsets will cause a device reset to occur.  This will
cause problems for any D State other than D3, since any state
information that the driver will expect to be present coming from
a D1 or D2 state will have been cleared.  This patch addes a
flag to the pci_dev structure to indicate that devices should
not use states D1 or D2, and will set that flag for the affected
chipsets.  This patch also modifies pci_set_power_state() so that
when a device driver tries to set the power state on
a device that is downstream from an affected chipset, or on one
of the affected devices it only allows state changes to or
from D0 & D3.  In addition, this patch allows the delay time
between D3->D0 to be changed via a quirk.  These chipsets also
need additional time to change states beyond the normal 10ms.

709cf5ea7a [PATCH] PCI: Clear abnormal poweroff flag on VIA southbridges, fix resume
Some VIA southbridges contain a flag in the ACPI register space that
indicates whether an abnormal poweroff has occured, presumably with the
intention that it can be cleared on clean shutdown.  Some BIOSes check this
flag at resume time, and will re-POST the system rather than jump back to
the OS if it's set.  Clearing it at boot time appears to be sufficient.
I'm not sure if drivers/pci/quirks.c is the right place to do it, but I'm
not sure where would be cleaner.

15e0c69436 [PATCH] ide: fix Jmicron support
Prior to 2.6.18rc1 you could install with devices on a JMicron chipset
using the "all-generic-ide" option. As of this kernel the AHCI driver
grabs the controller and rams it into AHCI mode losing the PATA ports
and making CD drives and the like vanish. The all-generic-ide option
fails because the AHCI driver grabbed the PCI device and reconfigured
it.

To fix this three things are needed.

#1 We must put the chip into dual function mode
#2 The AHCI driver must grab only function 0 (already in your rc1 tree)
#3 Something must grab the PATA ports

The attached patch is the minimal risk edition of this. It puts the chip
into dual function mode so that AHCI will grab the SATA ports without
losing the PATA ports. To keep the risk as low as possible the third
patch adds the PCI identifiers for the PATA port and the FN check to the
ide-generic driver. There is a more featured jmicron driver on its way
but that adds risk and the ide-generic support is sufficient to install
and run a system.

The actual chip setup done by the quirk is the precise setup recommended
by the vendor.

(The JMB368 appears only in the ide-generic entry as it has no AHCI so
does not need the quirk)

c67646641c Add PIIX4 APCI quirk for the 440MX chipset too
This is confirmed to fix a hang due to PCI resource conflicts with
setting up the Cardbus bridge on old laptops with the 440MX chipsets.
Original report by Alessio Sangalli, lspci debugging help by Pekka
Enberg, and trial patch suggested by Daniel Ritz:

  "From the docs available i would _guess_ this thing is really similar
   to the 82443BX/82371AB combination.  at least the SMBus base address
   register is hidden at the very same place (32bit at 0x90 in function
   3 of the "south" brigde)"

The dang thing is largely undocumented, but the patch was corroborated
by Asit Mallick:

  "I am trying to find the register information. 440MX is an integration of
   440BX north-bridge without AGP and PIIX4E (82371EB).  PIIX4 quirk
   should cover the ACPI and SMBus related I/O registers."

and verified to fix the problem by Alessio.

bd8481e164 [PATCH] PCI Bus Parity Status-broken hardware attribute, EDAC foundation
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.

a7b862f663 [PATCH] VIA quirk fixup, additional PCI IDs

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

2bd0fa3b62 [PATCH] add boot option to control Intel SATA/PATA combined mode
Combined mode sucks.  Especially when both libata and the legacy IDE
drivers try to drive ports on the same device, since that makes DMA
rather difficult.

This patch addresses the problem by allowing the user to control which
driver binds to the ports in a combined mode configuration.  In many
cases, they'll probably want the libata driver to control both ports
since it can use DMA for talking with ATAPI devices (when
libata.atapi_enabled=1 of course).  It also allows the user to get old
school behavior by letting the legacy IDE driver bind to both ports.
But neither is forced, the patch doesn't change current behavior unless
one of combined_mode=ide or combined_mode=libata is passed
on the boot line.  Either of those options may require you to access
your devices via different device nodes (/dev/hd* in the ide case
and /dev/sd* in the libata case), though of course if you have udev
installed nicely you may not notice anything.  :)

Let me know if the documentation is too cryptic, I'd be happy to expand
on it if necessary.  I think most users will want to boot with
'combined_mode=libata' and add 'options libata atapi_enabled=1'
to their modules.conf to get good DVD playing and disk behavior
(haven't tested CD or DVD writing though).

I'd much rather things behave sanely by default (i.e. DMA for devices on
both ports), but apparently that's difficult given the various chip
bugs and hardware configs out there (not to mention that people's
drives may suddenly change from /dev/hdc to /dev/sdb), so this boot
option may be the correct long term fix.

own PCI resource quirks, but for now just print out what it finds to
verify that the code does the right thing.

cc675230a9 [PATCH] Fix and clean up quirk_intel_ide_combined() configuration
This change makes quirk_intel_ide_combined() dependent on the precise
conditions under which it is needed:

* IDE is built in
* IDE SATA option is not set
* ata_piix or ahci drivers are enabled

This fixes an issue where some modular configurations would not cause
the quirk to be enabled.

085ae41f66 [PATCH] Make sparc64 use setup-res.c
There were three changes necessary in order to allow
sparc64 to use setup-res.c:

1) Sparc64 roots the PCI I/O and MEM address space using
   parent resources contained in the PCI controller structure.
   I'm actually surprised no other platforms do this, especially
   ones like Alpha and PPC{,64}.  These resources get linked into the
   iomem/ioport tree when PCI controllers are probed.

   So the hierarchy looks like this:

   iomem --|
	   PCI controller 1 MEM space --|
				        device 1
					device 2
					etc.
	   PCI controller 2 MEM space --|
				        ...
   ioport --|
            PCI controller 1 IO space --|
					...
            PCI controller 2 IO space --|
					...

   You get the idea.  The drivers/pci/setup-res.c code allocates
   using plain iomem_space and ioport_space as the root, so that
   wouldn't work with the above setup.

   So I added a pcibios_select_root() that is used to handle this.
   It uses the PCI controller struct's io_space and mem_space on
   sparc64, and io{port,mem}_resource on every other platform to
   keep current behavior.

2) quirk_io_region() is buggy.  It takes in raw BUS view addresses
   and tries to use them as a PCI resource.

   pci_claim_resource() expects the resource to be fully formed when
   it gets called.  The sparc64 implementation would do the translation
   but that's absolutely wrong, because if the same resource gets
   released then re-claimed we'll adjust things twice.

   So I fixed up quirk_io_region() to do the proper pcibios_bus_to_resource()
   conversion before passing it on to pci_claim_resource().

3) I was mistakedly __init'ing the function methods the PCI controller
   drivers provide on sparc64 to implement some parts of these
   routines.  This was, of course, easy to fix.

So we end up with the following, and that nasty SPARC64 makefile
ifdef in drivers/pci/Makefile is finally zapped.

a1740913ca [PATCH] via vt8237 apic bypass deassertion quirk
The VIA VT8237's IOAPIC sends 'APIC De-Assert Messages' by default, causing
another CPU interrupt when the IRQ pin is de-asserted.  This feature is
switched off by the patch to get rid of doubled ioapic level interrupt
rates.

On the 6700/6702 PXH part, a MSI may get corrupted if an ACPI hotplug
driver and SHPC driver in MSI mode are used together.

This patch will prevent MSI from being enabled for the SHPC as part of
an early pci quirk, as well as on any pci device which sets the no_msi
bit.

1e06276704 [PATCH] PCI: MSI functionality broken on Serverworks GC chipset
MSI functionality is broken on the GC_LE x86 chipset that Serverworks
developed and that is being used in various platforms today. Broadcom is
going to push out to the kernel MSI enabled Gigabit drivers (in the very
near future), and we would like to make sure that MSI does not get
enabled on any platforms using the GC_LE chipset (device id 0x17).
Following the AMD 8131 example, I am including a patch to disable MSI
functionality when a GCNB_LE is detected. Please let me know if there
are any issues with this. This is a permanent fix for this chipset, as
the hardware will not be updated.
