[SCSI] aacraid: Correct sa platform support. (Was: [Bug 8469] Bad EIP value on pentium3 SMP kernel-2.6.21.1) http://bugzilla.kernel.org/show_bug.cgi?id=8469 As discussed in the bugzilla outlined below, we have an sa based (Mustang) RAID adapter on the system, a Dell PERC2/QC. Affected controllers are HP NetRAID, Adaptec AAC-364, Dell PERC2/QC or Adaptec 5400S. This problem coincides with the introduction of the adapter_comm and adapter_deliver platform functions (Message [PATCH 1/4] aacraid: rework communication support code, January 23 2007, which initially migrated to 2.6.21) The panic occurs with an uninitialized adapter_deliver platform function pointer. The enclosed patch, unmodified as tested by Rainer, solves the problem. Signed-off-by: NMark Salyzyn <aacraid@adaptec.com> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

The Adapter build date that is to be printed on instantiation was not displayed as a result of the supplemental adapter information structure not being in sync with the Firmware; the driver took an early test cycle version that had a miss-sized padded region at the head and the structure was not re-checked at the end of qualification. The Build Date was not a priority and is merely a cosmetic enhancement, and the wrong location for the start of the structure member would not induce any side-effect problems. We updated the structure to match the actual format, and added the TSID (Tech Support Identification) value print, should it be present, to the adapter instantiation announcements during driver load. This later enhancement should improve the relationship between Service folk & Tech Support if the printed value of the TSID found it's way into the circular file labeled G... Neither of these values show in sysfs (yet). Signed-off-by: NMark Salyzyn <aacraid@adaptec.com> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

Just sweeping the floor clean in one spot. Some of these constants have never been used in the driver or in the firmware (and thus are meaningless). Triggered this patch because I discovered one of the unused constants was actually incorrect and figured it was better to clean them out than correct and update. There are no side effects at all regarding this patch, it is purely cosmetic. Signed-off-by: NMark Salyzyn <aacraid@adaptec.com> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

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.

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.

This patch recognizes this similarity and simplifies the driver to reduce it's code footprint and to improve maintainability by reducing the code duplication.

Received from Mark Salyzyn If the adapter should be in a blinkled (Firmware Assert) state when the driver loads, we will perform a warm restart of the Adapter Firmware to see if we can rescue the adapter. Possible causes of a blinkled can occur on some early release motherboard BIOSes, transitory PCI bus problems on embedded systems or non-x86 based architectures, transitory startup failures of early release drives or transitory hardware failures; some of which can bite the adapter later at runtime. Future enhancements will include recovery during runtime. Fixed extra whitespace space issue.

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.

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. Signed-off-by: NMark Salyzyn <aacraid@adaptec.com> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

Received from Mark Salyzyn from Adaptec. High Priority Queues have *never* been used in the entire history of the aac based adapters. Associated with this, aac_insert_entry can be removed, SavedIrql can be removed & padding variable can be removed. With the movement of SavedIrql out & replaced with an automatic variable qflags, the locking can be refined somewhat. The sparse warnings did not catch the need for byte swapping in the 'dprintk' debugging print macros, so fixed this up when this code was moved outside of the now refined locking.

New code from the Adaptec driver. Performance enhancement for newer adapters. I hope that this isn't too big for a single patch. I believe that other than the few small cleanups mentioned, that the changes are all related. - Added Variable FIB size negotiation for new adapters. - Added support to maximize scatter gather tables and thus permit requests larger than 64KB/each. - Limit Scatter Gather to 34 elements for ROMB platforms. - aac_printf is only enabled with AAC_QUIRK_34SG - Large FIB ioctl support - some minor cleanup Passes sparse check.
