      [SCSI] aacraid: apply commit config for reset_devices flag · 1208bab5
      由 Salyzyn, Mark 提交于 
      Under some conditions associated with the unclean transition to kdump,
the aacraid adapters will view the array as foreign and not export it to
prevent access and data manipulation. The solution is to submit a commit
configuration to export the devices since this is a expected behavior
when transitioning to a kdump kernel.

This patch adds the aacraid.reset_devices flag and when either this or
the global reset_devices flag is set, ensures that a commit config is
issued and extends the startup_timeout if it is set less than 5 minutes.

      [SCSI] aacraid: add support for FUA · 9d399cc7
      由 Salyzyn, Mark 提交于 
      Back in the beginning of last year we disabled mode page 8 and mode page
3f requests through device quirk bits instead of enhancing the driver to
respond to these mode pages because there was no apparent added value.

The Firmware that supports the new communication commands supports the
ability to force a write around of the adapter cache on a command by
command basis. In the attached patch we enable mode page 8 and 3f and
spoof the results as needed in order to *convince* the layers above to
submit writes with the FUA (Force Unit Attention) bit set if the file
system or application requires it, if the Firmware supports the write
through, or instead to submit a SYNCHRONIZE_CACHE if the Firmware does
not. The added value here is for file systems that benefit from this
functionality and for clustering or redundancy scenarios.

Caveats: By convince, we are responding with a minimal short 3 byte
content mode page 8, with only the data the SCSI layer needs and that we
can fill confidently. Applications that require the customarily larger
mode page 8 results may be confused by this(?). The FUA, or the
SYNCHRONIZE_CACHE only affect the cache on the controller. Our firmware
by default ensure that the underlying physical drives of the array have
their cache turned off so normally this is not a problem.

This attached patch is against current scsi-misc-2.6 and was unit tested
on RHEL5. Since this is a feature enhancement, it should not be
considered for any current stabilization efforts.

      [SCSI] aacraid: cleanup and version stamp driver · 802ae2f0
      由 Salyzyn, Mark 提交于 
      There is some residual cleanup of the last series of patches and the
need to bump the revision number to draw the line in the sand.

The cmd->SCp.phase is set in the aac_valid_context routine, then set
again to the same value following it's return. The cmd->scsi_done is set
twice in the aac_queuecommand routine. Free up the scsidev FILO in
aac_probe_container as it is not needed further down the function in any
case. Improve the efficiency of the abort handler kernel print
parameters. Bump revision number of driver to approximate the equivalent
in the Adaptec supplied version.

      [SCSI] aacraid: Improved error handling · 03d44337
      由 Mark Haverkamp 提交于 
      Received from Mark Salyzyn,

This set of fixes improve error handling stability of the driver. A popular
manifestation of the problems is an NULL pointer reference in the interrupt
handler when referencing portions of the scsi command context, or in the
scsi_done handling when an offlined device is referenced.

The aacraid driver currently does not get notification of orphaned command
completions due to devices going offline. The driver also fails to handle the
commands that are finished by the error handler, and thus can complete again
later at the hands of the adapter causing situations of completion of an
invalid scsi command context. Test Unit Ready calls abort assuming that the
abort was successful, but are not, and thus when the interrupt from the adapter
occurs, they reference invalid command contexts. We add in a TIMED_OUT flag to
inform the aacraid FIB context that the interrupt service should merely release
the driver resources and not complete the command up. We take advantage of this
with the abort handler as well for select abortable commands. And we detect and
react if a command that can not be aborted is currently still outstanding to
the controller when reissued by the retry mechanism.

      [SCSI] aacraid: Fix struct element name issue · a8166a52
      由 Mark Haverkamp 提交于 
      Received from Mark Salyzyn,

This patch is to resolve a namespace issue that will result from a patch
expected in the future that adds a new interface; rationalized as
correcting a long term issue where hw_fib, instead of hw_fib_va, refers
to the virtual address space and hw_fib_pa refers to the physical
address space. A small fragment of this patch also cleans up an unused
variable that was close to the patch fragments.

      [SCSI] aacraid: adjustable timeouts · 404d9a90
      由 Mark Haverkamp 提交于 
      Received From Mark Salyzyn

Add the ability to adjust for unusual corner case failures. Both of
these additional module parameters deal with embedded, non-intel or
complicated system scenarios.

Aif_timeout can be increased past the default 2 minute timeout to drop
application registrations when a system has an unusually high event load
resulting from continuing management requests, or simultaneous builds,
or sluggish user space as a result of system load.

Startup_timeout can be increased past the default 3 minute timeout to
drop an adapter initialization for systems that have a very large number
of targets, or slow to spin-up targets, or a complicated set of array
configurations that extend the time for the firmware to declare that it
is operational. This timeout would only have an affect on non-intel
based systems, as the (more patient) BIOS would generally be where the
startup delay would be dealt with.

      [SCSI] Fix aacraid regression · 7a9366e4
      由 Salyzyn, Mark 提交于 
      Juan was kind enough to linger on site, and work on a production
machine, to try the parameter to make the system stable. He discovered
that reducing the maximum transfer size issued to the adapter to 128KB
stabilized his system. This is related to an earlier change for the
2.6.13 tree resulting from Martin Drab's testing where the transfer size
was reduced from 4G to 256KB; we needed to go still further in scaling
back the request size.

Here is the patch that tames this regression.
