2014-03-15[SCSI] hpsa: poll controller to detect device change eventStephen M. Cameron3-0/+112
For shared SAS configurations, hosts need to poll Smart Arrays periodically in order to be able to detect configuration changes such as logical drives being added or removed from remote hosts. A register on the controller indicates when such events have occurred, and the driver polls the register via a workqueue and kicks off a rescan of devices if such an event is detected. Additionally, changes to logical drive raid offload eligibility are autodetected in this way. Signed-off-by: Stephen M.

This enables sending i/o's destined for RAID logical drives which can be serviced by a single physical disk down a different, faster i/o path directly to physical drives for certain logical volumes on SSDs bypassing the Smart Array RAID stack for a performance improvement.

2014-03-15[SCSI] hpsa: fix task management for mode-1 ioaccell pathScott Teel1-6/+21
For "mode 1" io accelerated commands, the command tag is in a different location than for commands that go down the normal RAID path, so the abort handler needs to take this into account.

2014-03-15[SCSI] hpsa: only allow REQ_TYPE_FS to use fast pathStephen M. Cameron1-1/+2
When commands sent down the "fast path" fail, they must be re-tried down the normal RAID path. We do this by kicking i/o's back to the scsi mid layer with a DID_SOFT_ERROR status, which causes them to be retried. This won't work for SG_IO's and other non REQ_TYPE_FS i/o's which could get kicked all the way back to the application, which may have no idea that the command needs resubmitting and likely no way to resubmit it in such a way the that driver can recognize it as a resubmit and send it down the normal RAID path. So we just always send non REQ_TYPE_FS i/o's down the normal RAID path, never down the "fast path". Signed-off-by: Stephen M.

2014-03-15[SCSI] hpsa: add support for 'fastpath' i/oMatt Gates3-19/+388

2014-03-15[SCSI] hpsa: use extended report luns command for HP SSD SmartPathMatt Gates2-5/+9
There is an extended report luns command which contains additional information about physical devices. In particular we need to get the physical device handle so we can use an alternate i/o path for fast physical devices like SSDs so we can speed up certain i/o's by bypassing the RAID stack code in the controller firmware.

2014-03-15[SCSI] pm80xx: Spinlock fixSuresh Thiagarajan3-142/+38
spin_lock_irqsave for the HBA lock is called in one function where flag is local to that function. Another function is called from the first function where lock has to be released using spin_unlock_irqrestore for calling task_done of libsas. In the second function also flag is declared and used. For calling task_done there is no need to enable the irq. So instead of using spin_lock_irqsave and spin_unlock_irqrestore, spin_lock and spin_unlock is used now. This also avoids passing the flags across all the functions where HBA lock is being used. Also removed redundant code.

2014-03-15[SCSI] hpsa: fixup MSI-X registrationHannes Reinecke1-14/+17
Commit 254f796b9f22b1944c64caabc356a56caaa2facd updated the driver to use 16 MSI-X vectors, despite the fact that older controllers would provide only 4. This was causing MSI-X registration to drop down to INTx mode. But as the controller support performant mode, the initialisation will become confused and cause the machine to stall during boot. This patch fixes up the MSI-X registration to re-issue the pci_enable_msix() call with the correct number of MSI-X vectors. With that the hpsa driver continues to works on older controllers like the P200. Signed-off-by: Hannes Reinecke <[email protected]> Acked-by: Stephen M.

2014-03-15[SCSI] dual scan thread bug fixJames Bottomley1-7/+16
In the highly unusual case where two threads are running concurrently through the scanning code scanning the same target, we run into the situation where one may allocate the target while the other is still using it. In this case, because the reap checks for STARGET_CREATED and kills the target without reference counting, the second thread will do the wrong thing on reap. Fix this by reference counting even creates and doing the STARGET_CREATED check in the final put.

2014-03-15[SCSI] fix our current target reap infrastructureJames Bottomley2-45/+74
This patch eliminates the reap_ref and replaces it with a proper kref. On last put of this kref, the target is removed from visibility in sysfs. The final call to scsi_target_reap() for the device is done from __scsi_remove_device() and only if the device was made visible. This ensures that the target disappears as soon as the last device is gone rather than waiting until final release of the device (which is often too long).
