      ahci: disable SNotification capability for ich8 · 1b677afd
      由 Shaohua Li 提交于 
      I obseved there is a sata_async_notification() for every ahci
interrupt. But the async notification does nothing (this is hard
disk drive and no pmp). This cause cpu wastes some time on sntf
register access.

It appears ICH AHCI doesn't support SNotification register, but the
controller reports it does. After quirking it, the async notification
disappears.

PS. it appears all ICH don't support SNotification register from ICH
manual, don't know if we need quirk all ICH. I don't have machines
with all kinds of ICH.

      ahci: filter FPDMA non-zero offset enable for Aspire 3810T · f80ae7e4
      由 Tejun Heo 提交于 
      Curiously, Aspire 3810T issues many SATA feature enable commands via
_GTF, of which one is invalid and another is not supported by the
drive.  In the process, it also enables FPDMA non-zero offset.
However, the feature also needs to be supported and enabled from the
controller and it's wrong to enable it from _GTF unless the controller
can do it by default.

Currently, this ends up enabling FPDMA non-zero offset only on the
drive side leading to NCQ command failures and eventual disabling of
NCQ.  This patch makes libata filter out FPDMA non-zero offset enable
for the machine.

This was reported by Marcus Meissner in bnc#522790.

      ahci: display all AHCI 1.3 HBA capability flags (v2) · 4c521c8e
      由 Robert Hancock 提交于 
      Update the AHCI driver to display all of the HBA capabilities defined in the
AHCI 1.3 specification. Some of these are in a new CAP2 (HBA Capabilities
Extended) register which is only defined on AHCI 1.2 or later. The spec says
that undefined registers should always return 0 on read, but to be safe we
assume a value of 0 unless the controller reports AHCI version 1.2 or later.
The value can also be retrieved through sysfs as with the existing capability
field.

For example, on an Intel Ibex Peak (PCH) controller:

ahci 0000:00:1f.2: flags: 64bit ncq sntf stag pm led clo pmp pio slum part ems
sxs apst

We don't do anything special with the new flags yet.

Also, change the code that displays the flags to use the same bit enumerations
that are used to control actual operation.

      ahci: disable 64bit DMA by default on SB600s · 2fcad9d2
      由 Tejun Heo 提交于 
      Till now only one board, ASUS M2A-VM, can do 64bit dma with recent
BIOSen.  Enabling 64bit DMA by default already broke three boards.
Enabling 64bit DMA isn't worth these regressions.  Disable 64bit DMA
by default and enable it only on boards which are known to work.

      Gigabyte GA-MA69VM-S2 can't do 64bit DMA either.  It's yet unknown
whether recent BIOS fixes the problem.  Blacklist regardless of BIOS
revisions for now.

      ahci: make ahci_asus_m2a_vm_32bit_only() quirk more generic · 03d783bf
      由 Tejun Heo 提交于 
      It turns out ASUS M2A-VM isn't the only one with the 32bit DMA
problem.  Make ahci_asus_m2a_vm_32bit_only() more generic using the
new dmi_get_date() and rename it to ahci_sb600_32bit_only().  Cut off
date is now pointed to by dmi_system_id->driver_data in "yyyymmdd"
format and it's now also allowed to be omitted.

      dmi: extend dmi_get_year() to dmi_get_date() · 3e5cd1f2
      由 Tejun Heo 提交于 
      There are cases where full date information is required instead of
just the year.  Add month and day parsing to dmi_get_year() and rename
it to dmi_get_date().

As the original function only required '/' followed by any number of
parseable characters at the end of the string, keep that behavior to
avoid upsetting existing users.

The new function takes dates of format [mm[/dd]]/yy[yy].  Year, month
and date are checked to be in the ranges of [1-9999], [1-12] and
[1-31] respectively and any invalid or out-of-range component is
returned as zero.

The dummy implementation is updated accordingly but the return value
is updated to indicate field not found which is consistent with how
other dummy functions behave.

      ahci: add warning messages for hp laptops with broken suspend · 9b10ae86
      由 Tejun Heo 提交于 
      Harddisks on HP dv[4-6] and HDX18 fail to come online after resume on
earlier BIOSen.  Fortunately, HP recently released BIOS updates for
all machines to fix the issue.  Detect old BIOSen, warn the user to
update BIOS on boot and suspend attempts and fail suspend.

Kudos to all the bug reporters.

      SATA AHCI: Blacklist system that spins off disks during ACPI power off · 1fd68434
      由 Rafael J. Wysocki 提交于 
      Some notebooks from HP have the problem that their BIOSes attempt to
spin down hard drives before entering ACPI system states S4 and S5.
This leads to a yo-yo effect during system power-off shutdown and the
last phase of hibernation when the disk is first spun down by the
kernel and then almost immediately turned on and off by the BIOS.
This, in turn, may result in shortening the disk's life times.

To prevent this from happening we can blacklist the affected systems
using DMI information.

Blacklist HP nx6310 that uses the AHCI driver.
