2010-03-03[SCSI] hpsa: Increase the number of scatter gather elements supported.Stephen M. Cameron
This uses the scatter-gather chaining feature of Smart Array controllers. 32 scatter-gather elements are embedded in the "command list", and the last element in the list may be marked as a "chain pointer", and point to an additional block of scatter gather elements. The precise number of scatter gather elements supported is dependent on the particular kind of Smart Array, and is determined at runtime by querying the hardware. Signed-off-by: Stephen M.

2010-03-03[SCSI] hpsa: remove scan threadMike Miller
The intent of the scan thread was to allow a UNIT ATTENTION/LUN DATA CHANGED condition encountered in the interrupt handler to trigger a rescan of devices, which can't be done in interrupt context. However, we weren't able to get this to work, due to multiple such UNIT ATTENTION conditions arriving during the rescan, during updating of the SCSI mid layer, etc. There's no way to tell the devices, "stand still while I scan you!" Since it doesn't work, there's no point in having the thread, as the rescan triggered via ioctl or sysfs can be done without such a thread.

2010-02-17[SCSI] hpsa: use scan_start and scan_finished entry points for scanningStephen M. Cameron
use scan_start and scan_finished entry points for scanning and route the CCISS_REGNEWD ioctl and sysfs triggering of same functionality through hpsa_scan_start. Signed-off-by: Stephen M. Cameron <scameron@beardog.cce.hp.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
2010-02-17[SCSI] hpsa: Fix p1210m LUN assignment.Stephen M. Cameron
The p1210m responsds to SCSI report LUNs, unlike traditional Smart Array controllers. This means that the bus, target, and lun assignments done by the driver cannot be arbitrary, but must match what SCSI REPORT LUNS returns. Signed-off-by: Stephen M.

2010-02-17[SCSI] hpsa: Allow multiple command completions per interrupt.Don Brace
This is done by adding support for the so-called "performant mode" (that's really what they called it). Smart Array controllers have a mode which enables multiple command completions to be delivered with a single interrupt, "performant" mode. We want to use that mode, as some newer controllers will be requiring this mode. Signed-off-by: Don Brace <brace@beardog.cce.hp.com> Signed-off-by: Stephen M.

2010-02-17[SCSI] hpsa: Use kernel integer types, not userland onesStephen M. Cameron

2009-12-10[SCSI] hpsa: add driver for HP Smart Array controllers.Stephen M. Cameron
This driver supports a subset of HP Smart Array Controllers. It is a SCSI alternative to the cciss driver.
