When any UFS host controller receives a TM(Task Management) response from a UFS device, UFS driver has been recognize like receiving a message of "Task Management Function Complete"(00h) in all cases, so far. That means there is no pending task for a tag of the TM request sent before in the UFS device. That's because the byte offset 6 in TM response which has been used to get a TM service response so far represents just whether or not a TM transmission passes. Regarding UFS spec, the correct byte offset to get TM service response is 15, not 6. I tested that UFS driver responds properly for the TM response from a UFS device with an reference board with exynos8890, as follow: No pending task -> Task Management Function Complete (00h) Pending task -> Task Management Function Succeeded (08h) [mkp: applied by hand] Signed-off-by:

If a VFC port gets unmapped in the VIOS, it may not respond with a CRQ init complete following H_REG_CRQ. If this occurs, we can end up having called scsi_block_requests and not a resulting unblock until the init complete happens, which may never occur, and we end up hanging I/O requests. This patch ensures the host action stay set to IBMVFC_HOST_ACTION_TGT_DEL so we move all rports into devloss state and unblock unless we receive an init complete.

Large PIO transfers are broken up into chunks to try to avoid disabling local IRQs for long periods. But IRQs are still disabled for too long and this causes SCC FIFO overruns during serial port transfers. This patch reduces the PIO chunk size to reduce interrupt latency to something on the order of milliseconds, at the expense of additional CPU overhead from extra iterations of the NCR5380_main() loop. That CPU overhead is a problem for slow machines (e.g. mac_scsi on 25 MHz 68030) but these machines generally use PDMA not PIO. This patch doesn't make the overhead any worse on my Mac LC III (because it only gets about 510 accesses per ms). This patch decreases disk performance by a fraction of one percent for dmx3191d on my 333 MHz PowerPC 750. Other affected hardware (such as g_NCR5380 on x86) was not tested but 5380 ISA cards generally use PDMA and not PIO. [mkp: fix whitespace] Signed-off-by:

The (re)initializing of the completion object should be done before we trigger the transfer. Doing this after triggering the hardware opens up a race window. Without the timeout we would problaly even deadlock. Use also reinit_completion because we initalize the whole data structure in csio_scscim_init().

When the v2 hw is attached with many disks through an expander, there may be OOB reset resulting in a PHY going down after the speed is negotiated (very low probability). This issue is resolved by modifying the link control registers to send three identify frames before the PHY is ready (according to 6.10.3.3.2 in SAS 3.0 spec) and close ready when the PHY is down.
