The REPORT SUPPORTED OPERATION CODES command can be used to query
whether a given opcode is supported by a device. Add a helper function
that allows us to look up commands.
We only issue RSOC if the device reports compliance with SPC-3 or
later. But to err on the side of caution we disable the command for ATA,
FireWire and USB.

Pull first round of SCSI updates from James Bottomley:
"This is a large set of updates, mostly for drivers (qla2xxx [including
support for new 83xx based card], qla4xxx, mpt2sas, bfa, zfcp, hpsa,
be2iscsi, isci, lpfc, ipr, ibmvfc, ibmvscsi, megaraid_sas).
There's also a rework for tape adding virtually unlimited numbers of

Calxeda highbank SATA phy has intermittent problems bringing up a link
with Gen3 drives. Retrying the phy hard reset can work-around this issue,
but each reset also disables spread spectrum support. The reset function
also needs to reprogram the phy to enable spread spectrum support.

The freescale V2 SATA controller checks if the received data length matches
the programmed length 'ttl', if not, it assumes that this is an error.
In ATAPI, the 'ttl' is based on max allocation length and not the actual
data transfer length, controller will raise 'DLM' (Data length Mismatch)
error bit in Hstatus register. Along with 'DLM', DE (Device error) and
FE (fatal Error) bits are also set in Hstatus register, 'E' (Internal Error)
bit is set in Serror register and CE (Command Error) and DE (Device error)
registers have the corresponding bit set. In this condition, we need to
clear errors in following way: in the service routine, based on 'DLM' flag,
HCONTROL[27] operation clears Hstatus, CE and DE registers, clear Serror
register.

Device Sleep is a feature as described in AHCI 1.3.1 Technical Proposal.
This feature enables an HBA and SATA storage device to enter the DevSleep
interface state, enabling lower power SATA-based systems.
Aggressive Device Sleep enables the HBA to assert the DEVSLP signal as
soon as there are no commands outstanding to the device and the port
specific Device Sleep idle timer has expired. This enables autonomous
entry into the DevSleep interface state without waiting for software
in power sensitive systems.
This patch enables Aggressive Device Sleep only if both host controller
and device support it.
Tested on AMD reference board together with Device Sleep supported device
sample.

libsas and ipr pass flags to ata_host_init that are meant for the port.
ata_host flags:
ATA_HOST_SIMPLEX = (1 << 0), /* Host is simplex, one DMA channel per host only */
ATA_HOST_STARTED = (1 << 1), /* Host started */
ATA_HOST_PARALLEL_SCAN = (1 << 2), /* Ports on this host can be scanned in parallel */
ATA_HOST_IGNORE_ATA = (1 << 3), /* Ignore ATA devices on this host. */
flags passed by libsas:
ATA_FLAG_SATA = (1 << 1),
ATA_FLAG_PIO_DMA = (1 << 7), /* PIO cmds via DMA */
ATA_FLAG_NCQ = (1 << 10), /* host supports NCQ */
The only one that aliases is ATA_HOST_STARTED which is a 'don't care' in
the libsas and ipr cases since ata_hosts from these sources are not
registered with libata.

Reuse ata_port_{suspend|resume}_common for sas. This path is chosen
over adding coordination between ata-tranport and sas-transport because
libsas wants to revalidate the domain at resume-time at the host level.
It can not validate links have resumed properly until libata has had a
chance to perform its revalidation, and any sane placing of an ata_port
in the sas-transport model would delay it's resumption until after the
host.
Export the common portion of port suspend/resume (bypass pm_runtime),
and allow sas to perform these operations asynchronously (similar to the
libsas async-ata probe implmentation). Async operation is determined by
having an external, rather than stack based, location for storing the
result of the operation.

Currently, SATA disk fua detection is disabled on default because most of
devices don't support this feature at that time. With the development of
technology, more and more SATA disks support this feature. So now we can enable
this detection on default.
Although fua detection is defined as a kernel module parameter, it is too hard
to set its value because it must be loaded and set before system starts up.
That needs to modify initrd file. So it is inconvenient for administrator who
needs to manage a huge number of servers.

I added my device to this whitelist in a custom built kernel and it

The mainboard MSI E350DM-E33 is advertised with 6 SATA ports.

of them kernel uses UDMA/33 mode due to cable detection:

This patch forces "short cable" mode on this board, as it seems clear that
the on-board SATA<->PATA "cable" is short.
With this patch the disk is configured for UDMA/100:

With addition of dummy clk_*() calls for non CONFIG_HAVE_CLK cases in
clk.h, there is no need to have clk code enclosed in #ifdef
CONFIG_HAVE_CLK, #endif macros.

Add support for instantiating this driver from device tree, and add
the necassary DT information to the kirkwood.dtsi file.
This is based on previous work by Michael Walle and Jason Cooper.

After merging the libata tree, today's [2012-07-01] linux-next build (x86_64
allmodconfig) failed like this:
drivers/ata/libata-acpi.c: In function 'ata_acpi_set_state':
drivers/ata/libata-acpi.c:872:5: error: too few arguments to function 'acpi_pm_device_sleep_state'
include/acpi/acpi_bus.h:418:5: note: declared here
Caused by commit 3bd46600a7a7 ("libata-acpi: add ata port runtime D3Cold
support") from the libata tree interacting with commit ee85f543710d
("ACPI/PM: specify lowest allowed state for device sleep state") from the
pci tree.
This patch adds ACPI_STATE_D3 as the new third parameter to
acpi_pm_device_sleep_state()

Two bits were appended to the end of the bitfield
list in struct scsi_device. Resolve that conflict
by including both bits.

Only channel 0 is currently support and the driver code is fixed on
channel 0. This patch lets device node specifying dma-channel in case
it is not 0. If no dma-channel property is specified, channel 0 is
used as default.

The function ata_ering_clear_cb is only referenced in this file and
should be marked static to prevent it from being exposed globally.
This quiets the sparse warning:
warning: symbol 'ata_ering_clear_cb' was not declared. Should it be static?

The hardreset operation is currently not supported. This causes
sometime the SATA driver does cause kernel crash because of
none-determined state.a This patch will fix the issue.
