* [SCSI] bfa: Defined a new LPS event to clear virtual link on a vportKrishna Gudipati2010-03-045-3/+97
| | | | | | | | | | | | Clear virtual links was not propagated upwards to bfa from fw. This resulted in HBA and switch being in an inconsistent state. So defined a new LPS event for clear virtual link on a vport, and also now clear virtual link on a baseport, is sent as a link down event from the fw.

* [SCSI] raid_attrs: fix dependency problemsJames Bottomley2010-03-032-0/+8
| | | | | | | | | | | | | | RAID attributes uses scsi_is_sdev_device() to gate some SCSI specific checking code. This causes two problems. Firstly if SCSI == n just defining scsi_is_sdev_device() to return false might not be enough to prevent gcc from emitting the code (and thus referring to undefined symbols), so this needs surrounding with an ifdef. Secondly, using scsi_is_sdev_device() when SCSI is either y or m gives a subtle problem in the m case: raid_attrs must also be m to use the symbol. Do the usual Kconfig jiggery-pokery to fix this.

| | | | | | | | | | | | | | 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.

* [SCSI] hpsa: remove scan threadMike Miller2010-03-032-166/+4
| | | | | | | | | | | | | | | | 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.

The power.async_suspend flag is also set for devices that don't have suspend or resume callbacks, because otherwise they would make the main suspend/resume thread wait for their "asynchronous" children (during suspend) or parents (during resume), effectively negating the possible gains from executing these devices' suspend and resume callbacks asynchronously.
