      [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: add restart adapter platform function · 8418852d
      由 Mark Haverkamp 提交于 
      Received from Mark Salyzyn,

This patch updates the adapter restart function to deal with some
adapters that have specific IOP reset needs. Since the code for
restarting the adapter was in two places, changed over to utilizing a
platform function in one place.

      Received From Mark Salyzyn

The queue tracking is just not being used, not even for debugging. Information
about outstanding commands can be acquired from the scsi structures.

      [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.

      Linux-2.6.12-rc2 · 1da177e4
      由 Linus Torvalds 提交于 
      Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
