This is normally optional, but for SSD Smart Path support (in subsequent patches) it is required. Signed-off-by:

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.

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. Reported-by:

Commit 254f796b 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:

When the host template doesn't declare an eh_host_reset_handler the eh_deadline mechanism is pointless and will set the device to offline. So disable eh_deadline if no eh_host_reset_handler is present. Signed-off-by:

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. Tested-by:

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). Reviewed-by:

qla2x00_mem_alloc() returns 1 on success and -ENOMEM on failure. On the one hand the caller assumes non-zero is success but on the other hand the caller also assumes that it returns an error code. I've fixed it to return zero on success and a negative error code on failure. This matches the documentation as well.

isci is needlessly tying libata's hands by returning SAM_STAT_CHECK_CONDITION to some ata errors. Instead, prefer SAS_PROTO_RESPONSE to let libata (via sas_ata_task_done()) disposition the device-to-host fis. For example isci is triggering an HSM Violation where AHCI is showing a simple media error for the same bus condition: isci: ata7.00: failed command: READ VERIFY SECTOR(S) ata7.00: cmd 40/00:01:00:00:00/00:00:00:00:00/e0 tag 0 res 01/04:00:00:00:00/00:00:00:00:00/e0 Emask 0x3 (HSM violation) ahci: ata6.00: failed command: READ VERIFY SECTOR(S) ata6.00: cmd 40/00:01:00:00:00/00:00:00:00:00/e0 tag 0 res 51/40:01:00:00:00/00:00:00:00:00/e0 Emask 0x9 (media error) Note that the isci response matches this from sas_ata_task_done(): /* We saw a SAS error. Send a vague error. */ [..] dev->sata_dev.fis[3] = 0x04; /* status err */ dev->sata_dev.fis[2] = ATA_ERR; The end effect is that isci is needlessly triggering hard resets when they are not necessary.

libsas sometimes short circuits timeouts to force commands into error recovery. It is misleading to log that the command timed-out in sas_scsi_timed_out() when in fact it was just queued for error handling. It's also redundant in the case of a true timeout as libata eh will detect and report timeouts via it's AC_ERR_TIMEOUT facility. Given that some environments consider "timeout" errors to be indicative of impending device failure demote the sas_scsi_timed_out() timeout message to be disabled by default. This parallels ata_scsi_timed_out(). [jejb: checkpatch fix] Reported-by:
