* [SCSI] fix up request buffer reference in various scsi driversChristoph Hellwig2006-06-06
| | | | | | | | | | | | Various scsi drivers use scsi_cmnd.buffer and scsi_cmnd.bufflen in their queuecommand functions. Those fields are internal storage for the midlayer only and are used to restore the original payload after request_buffer and request_bufflen have been overwritten for EH. Using the buffer and bufflen fields means they do very broken things in error handling. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] aacraid: adjustable timeoutsMark Haverkamp2006-05-20
| | | | | | | | | | | | | | | | | | | | | | | | 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] aacraid: use no_uld_attach flagMark Haverkamp2006-02-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Received From Mark Salyzyn. In order to support user tools accessing the array components (SMART, Mode Page information, Cache page adjustments, WWN determination, Firmware updates etc), we take advantage of the no_uld_attach flag and deprecate the code that filters Inquiries to block the requests to array components. The quirk prevents the sd layer from attaching to the components. We also took the opportunity to balance the queue depths based on the total adapter queue depth to the array devices to reduce the chances of starvation.

* | [SCSI] Fix aacraid regressionSalyzyn, Mark2005-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Mark Salyzyn <aacraid@adaptec.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* | [SCSI] aacraid: remove aac_insert_entryMark Haverkamp2005-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Received from Mark Salyzyn from Adaptec. The size of the command packet's scatter gather list maximum size was miscalculated in the low range leading to the driver initialization limiting the maximum i/o size that could go to the Adapter. There were no negative operational side effects resulting from this bad math, only a subtle limit in performance of the Adapter at the top end of the range.

* | [SCSI] aacraid: initialization timeoutMark Haverkamp2005-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Received from Mark Salyzyn from Adaptec. In the rare instances where the adapter, or the motherboard, is misbehaving; driver initialization or shutdown becomes problematic. By introducing a 3 minute timeout on the first interrupt driven command during initialization, or the issuance of the adapter shutdown command during driver unload, we can resolve the lockup problems induced by common (but rare) hardware misbehaviors. The timeout during initialization, should it occur, is accompanied by a message presented to the console and the logs indicating that the user should inspect and resolve problems with interrupt routing.
