Intel host controllers support the setting of latency tolerance. Accordingly, implement the PM QoS ->set_latency_tolerance() callback. The raw register values are also exposed via debugfs.

It was observed on an ISP8324 16Gb HBA with fw=8.08.203 (d0d5) in a PowerPC64 machine that pkt->entry_type was MBX_IOCB_TYPE/0x39 with an sp->type SRB_SCSI_CMD which is invalid and should not be possible. Reading the entry_type from the crash dump shows the expected value of STATUS_TYPE/0x03 but the call trace shows that qla24xx_mbx_iocb_entry() is used. Add a check to verify for consistency and reset the HBA if an invalid state is reached. Obviously, this is only a workaround until the real problem is solved.

Emit a warning when ->done or ->free are called on an already freed srb. There is a hidden use-after-free bug in the driver which corrupts the srb memory pool which originates from the cleanup callbacks. An extensive search didn't bring any lights on the real problem. The initial fix was to set both pointers to NULL and try to catch invalid accesses. But instead the memory corruption was gone and the driver didn't crash. Since not all calling places check for NULL pointer, add explicitly default handlers. With this we workaround the memory corruption and add a debug help.

In sas_notify_lldd_dev_found(), if we can't allocate the necessary resources, then it seems like the wrong thing to mark the device as found and to increment the reference count.

Firmware expects E_D_TOV field in connection offload parameters as “msec”. Earlier incorrect value (100ms), was leading to abort from driver in the case when data frames for read take more than 100ms from target side, resulting in firmware reporting E_D_TOV expiration.

The error recovery is handled by management firmware (MFW) with the help of qed/qedi drivers. Upon detecting errors, driver informs MFW about this event which in turn starts a recovery process. MFW sends ERROR_RECOVERY notification to the driver which performs the required cleanup/recovery from the driver side.

While aborting the I/O, the firmware cleanup task timed out and driver deleted the I/O from active command list. Some time later the firmware sent the cleanup task response and driver again deleted the I/O from active command list causing firmware to send completion for non-existent I/O and list_del corruption of active command list. Add fix to check if I/O is present before deleting it from the active command list to ensure firmware sends valid I/O completion and protect against list_del corruption.

VIOS partitions with SLI-4 enabled Emulex adapters will be capable of driving I/O in parallel through mulitple work queues or channels, and with new hypervisor firmware that supports multiple interrupt sources an ibmvfc NPIV single initiator can be modified to exploit end-to-end channelization in a PowerVM environment. VIOS hosts will also be able to expose fabric perfromance impact notifications (FPIN) via a new asynchronous event to ibmvfc clients that advertise support via IBMVFC_CAN_HANDLE_FPIN in their capabilities flag during NPIV_LOGIN. This patch introduces three new Management Datagrams (MADs) for channelization support negotiation as well as the FPIN asynchronous event and FPIN status flags. Follow up work is required to plumb the ibmvfc client driver to use these new interfaces. Link: https://lore.kernel.org/r/20200904232936.840193-2-tyreld@linux.ibm.comSigned-off-by:
