      jmicron: update quirk for JMB361/3/5/6 · 3a9e3a51
      由 Tejun Heo 提交于 
      Set bits 0, 4, 5 and 7 of PCI configuration register 0x40 in the
quirk.  This has the following effects and is recommended by the
vendor.

* Force enable of IDE channels (used to be left alone as BIOS
  configured)

* Change initial phase behavior of PIO cycle such that the host pulls
  down the bus instead of tristating it.  Vendor recommends this
  setting.

The above settings are better for the current generation of
controllers and needed for the upcoming next generation.

Tested on JMB363.

      libata/IDE: remove combined mode quirk · 8cdfb29c
      由 Jeff Garzik 提交于 
      Both old-IDE and libata should be able handle all controllers and
devices found using normal resource reservation methods.

This eliminates the awful, low-performing split-driver configuration
where old-IDE drove the PATA portion of a PCI device, in PIO-only mode,
and libata drove the SATA portion of the /same/ PCI device, in DMA mode.
Typically vendors would ship SATA hard drive / PATA optical
configuration, which would lend itself to slow (PIO-only) CD-ROM
performance.

For Intel users running in combined mode, it is now wholly dependent on
your driver choice (potentially link order, if you compile both drivers
in) whether old-IDE or libata will drive your hardware.

In either case, you will get full performance from both SATA and PATA
ports now, without having to pass a kernel command line parameter.

      [PATCH] msi: sanely support hardware level msi disabling · f5f2b131
      由 Eric W. Biederman 提交于 
      In some cases when we are not using msi we need a way to ensure that the
hardware does not have an msi capability enabled.  Currently the code has been
calling disable_msi_mode to try and achieve that.  However disable_msi_mode
has several other side effects and is only available when msi support is
compiled in so it isn't really appropriate.

Instead this patch implements pci_msi_off which disables all msi and msix
capabilities unconditionally with no additional side effects.

pci_disable_device was redundantly clearing the bus master enable flag and
clearing the msi enable bit.  A device that is not allowed to perform bus
mastering operations cannot generate intx or msi interrupt messages as those
are essentially a special case of dma, and require bus mastering.  So the call
in pci_disable_device to disable msi capabilities was redundant.

quirk_pcie_pxh also called disable_msi_mode and is updated to use pci_msi_off.

      ahci/pata_jmicron: match class not function number · e34bb370
      由 Tejun Heo 提交于 
      Make jmiron_ata quirk update pdev->class after programming the device
and update ahci and pata_jmicron such that they match class code
instead of checking function number manually.  For ahci, it matches
for vendor and class.  For pata_jmicron, it matches vendor, device and
class as IDE class isn't as well defined as AHCI class.

This makes jmicron device matching more conventional and script
friendly.

      jmicron ATA: reimplement jmicron ATA quirk · 5ee2ae7f
      由 Tejun Heo 提交于 
      Reimplement jmicron ATA quirk.

* renamed to quirk_jmicron_ata()
* quirk is invoked only for the affected controllers
* programming is stricter.  e.g. conf5 bit24 is cleared if
  unnecessary.
* code factored for readability
* JMB360 and JMB368 are programmed into proper mode

Verified on JMB360, 363 and 368.

      ahci/pata_jmicron: fix JMicron quirk · 77280989
      由 Tejun Heo 提交于 
      For all JMicrons except for 361 and 368, AHCI mode enable bits in the
Control(1) should be set.  This used to be done in both ahci and
pata_jmicron but while moving programming to PCI quirk, it was removed
from ahci part while still left in pata_jmicron.

The implemented JMicron PCI quirk was incorrect in that it didn't
program AHCI mode enable bits.  If pata_jmicron is loaded first and
programs those bits, the ahci ports work; otherwise, ahci device
detection fails miserably.

This patch makes JMicron PCI quirk clear SATA IDE mode bits and set
AHCI mode bits and remove the respective part from pata_jmicron.
Tested on JMB361, 363 and 368.
