      Revert unintentional and bogus change to drivers/pci/quirks.c · 0c0e4668
      由 Linus Torvalds 提交于 
      In commit 4e8a5201 ("[PKT_SCHED] netem:
Orphan SKB when adding to queue.") Davem mistakenly also included a
temporary diff in his tree that disabled the pci_fixup_video VGA quirk,
which broke sparc64.

This reverts that part of the commit. Sayeth Davem:

  "Greg KH has a patch coming to you soon which will move that VGA code
   back into x86/x86_64/IA64 specific areas and will fix the sparc64
   problem properly."

Special thanks to Claudio Martins <ctpm@ist.utl.pt> for noticing the
error in the first place.

      [PATCH] PCI quirks update · 236561e5
      由 Alan Cox 提交于 
      This fixes two things

Firstly someone mistakenly used "errata" for the singular.  This causes
Dave Woodhouse to emit diagnostics whenever the string is read, and so
should be fixed.

Secondly the AMD AGP tunnel has an erratum which causes hangs if you try
and do direct PCI to AGP transfers in some cases.  We have a flag for
PCI/PCI failures but we need a different flag for this really as in this
case we don't want to stop PCI/PCI transfers using things like IOAT and the
new RAID offload work.

I'll post some updates to make proper use of the PCIAGP flag in the
media/video drivers to Mauro.

      [PATCH] PCI: PCIE power management quirk · ffadcc2f
      由 Kristen Carlson Accardi 提交于 
      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.

      [PATCH] PCI: Clear abnormal poweroff flag on VIA southbridges, fix resume · 709cf5ea
      由 Matthew Garrett 提交于 
      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.

      [PATCH] ide: fix Jmicron support · 15e0c694
      由 Alan Cox 提交于 
      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)

      Add PIIX4 APCI quirk for the 440MX chipset too · c6764664
      由 Linus Torvalds 提交于 
      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.

      [PATCH] PCI Quirk: 1K I/O space granularity on Intel P64H2 · 9d265124
      由 Daniel Yeisley 提交于 
      I've implemented a quirk to take advantage of the 1KB I/O space
granularity option on the Intel P64H2 PCI Bridge.  I had to change
probe.c because it sets the resource start and end to be aligned on 4k
boundaries (after the quirk sets them to 1k boundaries).  I've tested
this patch on a Unisys ES7000-600 both with and without the 1KB option
enabled.  I also tested this on a 2 processor Dell box that doesn't have
a P64H2 to make sure there were no negative affects there.

      [PATCH] add boot option to control Intel SATA/PATA combined mode · 2bd0fa3b
      由 Jesse Barnes 提交于 
      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.
