RX_WATER_MARK sets the number of locations in Rx FIFO that can be used before
the transport layer instructs the link layer to transmit HOLDS. Note that it
can take some time for the HOLDs to get to the other end, and that in the
interim there must be enough room in the FIFO to absorb all data that could
arrive.Update the new recommended value to 16.

When a single device error is detected, the device under the error
is indicated by the error bit set in the DER. There is a one to one
mapping between register bit and devices on Port multiplier(PMP)
i.e. bit 0 represents PMP device 0 and bit 1 represents PMP device
1 etc.Current implementation treats Device error register value as device
number not set of bits representing multiple device on PMP. It is
changed to consider bit level.No need to check for each set bit as all command is going to be
aborted.Signed-off-by: Ashish Kalra

Right at the moment, the libata error handler is incredibly
monolithic. This makes it impossible to use from composite drivers
like libsas and ipr which have to handle error themselves in the first
instance.The essence of the change is to split the monolithic error handler
into two components: one which handles a queue of ata commands for
processing and the other which handles the back end of readying a
port. This allows the upper error handler fine grained control in
calling libsas functions (and making sure they only get called for ATA
commands whose lower errors have been fixed up).Signed-off-by: James Bottomley
Signed-off-by: Jeff Garzik -
The SCSI host eh_cmd_q should be protected by the host lock (not the
port lock). This probably doesn't matter that much at the moment,
since we try to serialise the add and eh pieces, but it might matter
in future for more convenient error handling. Plus this switches
libata to the standard eh pattern where you lock, remove from the cmd
queue to a local list and unlock and then operate on the local list.Signed-off-by: James Bottomley
Signed-off-by: Jeff Garzik -
For historical reasons, libsas uses the scsi host lock as the ata port
lock, and libata always uses the ata host. For the old eh, this was
largely irrelevant since the two locks were never mixed inside the
code. However, the new eh has a case where it nests acquisition of
the host lock inside the port lock (this does look rather deadlock
prone). Obviously this would be an instant deadlock if the port lock
were the host lock, so switch the libsas paths to use the ata host
lock as well.Signed-off-by: James Bottomley
Signed-off-by: Jeff Garzik -
The function ata_sas_port_init() has always really done its own thing.
However, as a precursor to moving to the libata new eh, it has to be
properly using the standard libata scan paths. This means separating
the current libata scan paths into pieces which can be shared with
libsas and pieces which cant (really just the async call and the host
scan).Signed-off-by: James Bottomley

ata_eh_analyze_serror() suppresses hotplug notifications if LPM is
being used because LPM generates spurious hotplug events. It compared
whether link->lpm_policy was different from ATA_LPM_MAX_POWER to
determine whether LPM is enabled; however, this is incorrect as for
drivers which don't implement LPM, lpm_policy is always
ATA_LPM_UNKNOWN. This disabled hotplug detection for all drivers
which don't implement LPM.Fix it by comparing whether lpm_policy is greater than
ATA_LPM_MAX_POWER.Signed-off-by: Tejun Heo

ata_pio_sectors() expects buffer for each sector to be contained in a
single page; otherwise, it ends up overrunning the first page. This
is achieved by setting queue DMA alignment. If sector_size is smaller
than PAGE_SIZE and all buffers are sector_size aligned, buffer for
each sector is always contained in a single page.This wasn't applied to ATAPI devices but IDENTIFY_PACKET is executed
as ATA_PROT_PIO and thus uses ata_pio_sectors(). Newer versions of
udev issue IDENTIFY_PACKET with unaligned buffer triggering the
problem and causing oops.This patch fixes the problem by setting sdev->sector_size to
ATA_SECT_SIZE on ATATPI devices and always setting DMA alignment to
sector_size. While at it, add a warning for the unlikely but still
possible scenario where sector_size is larger than PAGE_SIZE, in which
case the alignment wouldn't be enough.Signed-off-by: Tejun Heo
