      [SCSI] aacraid: fix shutdown handler to also disable interrupts. · 94774a3a
      由 Salyzyn, Mark 提交于 
      Moves quiesce, thread and interrupt shutdown into aacraid drivers'
.shutdown handler. This fix to the aac_shutdown handler will remove the
superfluous reset of the adapter during a (clean) kexec.

This fix may mitigate the active investigation 'kexec and aacraid
broken' but it is unlikely to affect the root cause (issue likely
present in both kexec and kdump). This patch reduces the chance the
problem will occur with a kexec. The fix for root cause is currently
expected to be the minimum value check to the aacraid.startup_timeout
driver variable after an adapter reset within aacraid_commit_reset.patch
submitted on 05/22/2007 and awaiting testing by Yinghai to confirm.

      [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: merge rx and rkt code · 76a7f8fd
      由 Mark Haverkamp 提交于 
      Received from Mark Salyzyn:

The only real difference between the rkt and rx platform modules is the
offset of the message registers. This patch recognizes this similarity
and simplifies the driver to reduce it's code footprint and to improve
maintainability by reducing the code duplication.

Visibly, the 'rkt.c' portion of this patch looks more complicated than
it really is. View it as retaining the rkt-only specifics of the
interface.

      [SCSI] aacraid: expose physical devices · 653ba58d
      由 Mark Haverkamp 提交于 
      Received from Mark Salyzyn:

I am placing this functionality into an insmod parameter. Normally the physical
components are exported to sg, and are blocked from showing up in sd.

Note that the pass-through I/O path via the driver through the Firmware to the
physical disks is not an optimized path, the card is designed for Hardware
RAID, elevator sorting and caching. This should not be used as a means for
utilizing the aacraid based controllers as a generic scsi/SATA/SAS controller,
performance should suck by a few percentage points, any RAID meta-data on the
drives will confuse the controller about who owns the drives and there is a
high risk of destroying content in both directions. Unreliable and for
experimentation or strange controlled circumstances only.
