The mpt2sas driver wants to use transport layer retries (TLR) so the simplest thing to do seems to be to add the enabling flags and checks to the SAS transport class, since they're a SAS specific protocol feature. Signed-off-by:James Bottomley <James.Bottomley@suse.de>

A Gentoo bug report [1] showed that as of 2.6.31 lpfc only uses INTx interrupts. This patch restores lpfc's ability to support MSI-X/MSI interrupts that the "Addition of SLI4 Interface - Base Support" patch [2] broke. It reestablishes MSI-X as the default interrupt method and in case MSI-X is not supported lpfc_sli{4,}_enable_intr fallbacks to MSI and then to INTx. [1]: http://bugs.gentoo.org/show_bug.cgi?id=296319 [2]: commit da0436e9 [James Smart: Background: Nothing Broke. This was intended. We had originally enabled MSI-X by default, but in qualification within the last 12 months, we encountered a major catch-22: There were at least 4 platforms, from 2 major OEMs, that : - Say they support MSI-X - platform routines work and act as if they do. - We enable it, generate a test interrupt to check they really do deliver it, and it works. - But shortly after attachment, the system hangs or loses interrupts, resulting in a bad system behavior. Given the distro's picking up the 2.6.32 kernel, we had to stick with a default of MSI-X off, with user-enabled MSI-X as these platforms couldn't get fixed. However, we're also now encountering platforms that require MSI-X and never INTx, so we must change. It's desired also for also for performance reasons. So - now (2.6.33) is the right time to re-enable MSI-X by default. ] [jejb: fix up comment on default values] Signed-off-by:George Kadianakis <desnacked@gmail.com> Acked-by:

Further to the lsml thread titled: "does scsi_io_completion need to dump sense data for ata pass through (ck_cond = 1) ?" This is a patch to skip logging when the sense data is associated with a SENSE_KEY of "RECOVERED_ERROR" and the additional sense code is "ATA PASS-THROUGH INFORMATION AVAILABLE". This only occurs with the SAT ATA PASS-THROUGH commands when CK_COND=1 (in the cdb). It indicates that the sense data contains ATA registers. Smartmontools uses such commands on ATA disks connected via SAT. Periodic checks such as those done by smartd cause nuisance entries into logs that are: - neither errors nor warnings - pointless unless the cdb that caused them are also logged Signed-off-by:Douglas Gilbert <dgilbert@interlog.com> Signed-off-by:

There is a 'ioprio' field in the BIO and the Request structure. check this priority field and set MPI_SCSIIO_CONTROL_HEADOFQ to pass down I/O priority. An enhancement to the LSI Disk Array Controller firmware is being developed to look at the Head Of Queue bit to allow I/Os with the HOQ bit set to be processed before I/Os which do not have the HOQ bit set. In order to set the HOQ bit, the mpt fusion driver needs to look at the 'ioprio' field in the request structure associated with the scsi command. Signed-off-by:

The mac_esp PIO algorithm no longer works in 2.6.31 and crashes my Centris 660av. So here's a better one. Also, force async with esp_set_offset() rather than esp_slave_configure(). One of the SCSI drives I tested still doesn't like the PIO mode and fails with "esp: esp0: Reconnect IRQ2 timeout" (the same drive works fine in PDMA mode). This failure happens when esp_reconnect_with_tag() tries to read in two tag bytes but the chip only provides one (0x20). I don't know what causes this. I decided not to waste any more time trying to fix it because the best solution is to rip out the PIO mode altogether and use the DMA engine. Signed-off-by:

Currently dev_loss_tmo is capped by SCSI_DEVICE_BLOCK_MAX_TIMEOUT. This causes problem with multipathing when the 'no_path_retry' setting exceeds the dev_loss_tmo setting, as then the system might run into a deadlock when all paths have been removed temporarily for longer than dev_loss_tmo. The principal reasons for the capping has been that we should not allow a remote port to remain in status 'blocked' indefinitely, so the capping is there to ensure that the port status is being reset eventually. However, the fast_io_fail_tmo will also move the remote port out of the 'blocked' state, so for any HBA driver implementing both the capping should really be on the fast_io_fail_tmo, and not on the dev_loss_tmo. This patch implements just that, ie the fast_io_fail_tmo is capped to SCSI_DEVICE_BLOCK_TIMEOUT and the capping is removed from dev_loss_tmo when fast_io_fail_tmo is set. This allows us to synchronize the dev_loss_tmo setting to the 'no_path_retry' setting from multipathing thus avoiding the deadlock. Signed-off-by:

Introduce a zfcp callback for timeouts triggered from FC BSG. With zfcp, the underlying hardware cannot abort CT or ELS requests, so there is nothing to do when the block layer timeout expires. To avoid interference with the block layer timeout, simply indicate that the block layer timer should be reset. The timer running in the hardware for the pending CT or ELS request will return the request when it expires. Signed-off-by:
