* [SCSI] hpsa: Increase the number of scatter gather elements supported.Stephen M. Cameron2010-03-03
| | | | | | | | | | | | | | 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.

* [SCSI] hpsa: remove scan threadMike Miller2010-03-03
| | | | | | | | | | | | | | | | 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.

* [SCSI] hpsa: fix bug in adjust_hpsa_scsi_tableStephen M. Cameron2010-02-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fix bug in adjust_hpsa_scsi_table which caused devices which have changed size, etc. to do the wrong thing. The problem was as follows: The driver maintains its current idea of what devices are present in the h->dev[] array. When it updates this array, it scans the hardware, and produces a new list of devices, call it sd[], for scsi devices. Then, it compares each item in h->dev[] vs. sd[], and any items which are not present sd it removes from h->dev[], and any items present in sd[], but different, it modifies in h->dev[]. Then, it looks for items in sd[] which are not present in h->dev[], and adds those items into h->dev[]. All the while, it keeps track of what items were added and removed to/from h->dev[]. Finally, it updates the SCSI mid-layer by removing and adding the same devices it removed and added to/from h->dev[]. (modified devices count as a remove then add.) originally, when a "changed" device was discovered, it was removed then added to h->dev[]. The item was added to the *end* of h->dev[]. And, the item was removed from sd[] as well (nulled out). As it processed h->dev[], these newly added items at the end of the list were encountered, and sd[] was searched, but those items were nulled out. So they ended up getting removed immediately after they were added. The solution is to have a way to replace items in the h->dev[] array instead of doing a remove + add. Then the "changed" items. are not encountered a second time, and removed. Signed-off-by: Stephen M. Cameron <scameron@beardog.cce.hp.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

* [SCSI] hpsa: Allow multiple command completions per interrupt.Don Brace2010-02-17
| | | | | | | | | | | | | 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.
