2008-01-23[SCSI] aacraid: add parameter to control FUA and SYNCHRONIZE_CACHE policySalyzyn, Mark1-0/+2
aacraid.cache parameter, Disable Queue Flush commands: bit 0 - Disable FUA in WRITE SCSI commands bit 1 - Disable SYNCHRONIZE_CACHE SCSI command bit 2 - Disable only if Battery not protecting adapter supplied Cache e.g.: aacraid.cache=7 will disable the FUA and SYNCHRONIZE_CACHE commands if the adapter has reported that it's cache is battery backed up. This parameter permits experimentation with tradeoffs between performance and caching policy.

2008-01-11[SCSI] aacraid: fix driver failure with Dell PowerEdge Expandable RAID ↵Salyzyn, Mark1-0/+6
Controller 3/Di As reported in http://bugzilla.kernel.org/show_bug.cgi?id=3D9133 it was discovered that the PERC line of controllers lacked a key 64 bit ScatterGather capable SCSI pass-through function. The adapters are still capable of 64 bit ScatterGather I/O commands, but these two can not be mixed. This problem was exacerbated by the introduction of the SCSI Generic access to the DASD physical devices. The fix for users before this patch is applied is aacraid.dacmode=3D0 on the kernel command line to disable 64 bit I/O. The enclosed patch introduces a new adapter quirk and tries to limp along by enabling pass-through in situations where memory is 32 bit addressable on 64 bit machines, or disable the pass-through functions altogether. I expect that the check for 32 bit addressable memory to be controversial in that it can be incorrect in non-Dell non-Intel systems that PERC would never be installed under, the alternative is to disable pass-through in all cases which could be reported as another regression. Pass-through is used for SCSI Generic access to the physical devices, or for the management applications to properly function. In systems where this patch has disabled pass-through because it is unsupportable in combination with I/O performance, the user can choose to enable pass-through by turning off dacmode (aacraid.dacmode=3D0) or limiting the discovered kernel memory (mem=3D4G) with an associated loss in runtime performance. If we chose instead to turn off 64 bit dacmode for the adapters with this quirk, then this would be reported as another regression.

2007-07-18[SCSI] aacraid: add vpd to inquirySalyzyn, Mark1-0/+14
Report VPD inquiry page 0x80 with an unique array creation serial number (CUID). When an array is created, the metadata stored on the physical drives gets an unique serial number. This serial number remains constant through array morphing or migration to other controllers. This patch is a forward port and modification to survive morphing and migration operations, of a similar piece of (un-attributed author) code added to the SLES10 SP1 aacraid driver. To test the results of the patch, observe that /dev/disk/by-id/ entries will show up for the arrays resulting from the udev rules. Also, as per the udev rules, 'scsi_id -g -x -a -s /block/sd? -d /dev/sd?' will report the ID_SERIAL as constructed from the inquiry data. It was reported to me that the 'ADPT' leading the serial number was bad form, that the inquiry vendor field was enough to differentiate the storage uniquely. Subsequent search found that another Adaptec AAC based driver reported the 8 hex serial number only without such adornments, so dropped ADPT to match. Resubmitting the patch with this alteration.

2007-05-22[SCSI] aacraid: apply commit config for reset_devices flagSalyzyn, Mark1-0/+2
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.

2007-05-22[SCSI] aacraid: add support for FUASalyzyn, Mark1-3/+6
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.

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.

2007-04-01[SCSI] aacraid: fix print of Firmware Build Date and add TSIDSalyzyn, Mark1-2/+17
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...

2007-03-20[SCSI] aacraid: Improved error handlingMark Haverkamp1-1/+0
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.

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.
