Pull SCSI updates from James Bottomley: "Usual driver updates (qla2xxx, mpi3mr, mpt3sas, ufs) plus assorted cleanups and fixes. The biggest core change is the massive code motion in the sd driver to remove forward declarations and the most significant change is to enumify the queuecommand return" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (78 commits) scsi: csiostor: Fix dereference of null pointer rn scsi: buslogic: Reduce stack usage scsi: ufs: host: mediatek: Require CONFIG_PM scsi: ufs: mediatek: Fix page faults in ufs_mtk_clk_scale() trace event scsi: smartpqi: Fix memory leak in pqi_report_phys_luns() scsi: mpi3mr: Make driver probing asynchronous scsi: ufs: core: Flush exception handling work when RPM level is zero scsi: efct: Use IRQF_ONESHOT and default primary handler scsi: ufs: core: Use a host-wide tagset in SDB mode scsi: qla2xxx: target: Add WQ_PERCPU to alloc_workqueue() users scsi: qla2xxx: Add WQ_PERCPU to alloc_workqueue() users scsi: qla4xxx: Add WQ_PERCPU to alloc_workqueue() users scsi: mpi3mr: Driver version update to 8.17.0.3.50 scsi: mpi3mr: Fixed the W=1 compilation warning scsi: mpi3mr: Record and report controller firmware faults scsi: mpi3mr: Update MPI Headers to revision 39 scsi: mpi3mr: Use negotiated link rate from DevicePage0 scsi: mpi3mr: Avoid redundant diag-fault resets scsi: mpi3mr: Rename log data save helper to reflect threaded/BH context scsi: mpi3mr: Add module parameter to control threaded IRQ polling ...

scsi: mpi3mr: Use negotiated link rate from DevicePage0

2026-01-24T03:16:16+00:00

Firmware populates the negotiated SAS link rate in DevicePage0 during device discovery. Update mpi3mr to cache this value while initializing the target device. When available, the cached link rate is used instead of issuing additional SAS PHY or expander PHY page reads. If the DevicePage0 value is missing or invalid, the driver falls back to the existing PHY-based mechanism.

scsi: mpi3mr: Read missing IOCFacts flag for reply queue full overflow

2025-12-17T02:19:26+00:00

The driver was not reading the MAX_REQ_PER_REPLY_QUEUE_LIMIT IOCFacts flag, so the reply-queue-full handling was never enabled, even on firmware that supports it. Reading this flag enables the feature and prevents reply queue overflow.

scsi: mpi3mr: Support for Segmented Hardware Trace buffer

2025-02-04T02:46:40+00:00

Allocate segmented trace buffer if firmware advertises the capability in IOCfacts. Upon driver load, read the trace buffer size from driver page 1, calculate the required segments for trace buffer, and allocate segmented buffers. Each segment is 4096 bytes in size. While posting driver diagnostic buffer to firmware, advertise that trace buffer is segmented.

Make driver use the timestamp update interval value provided by firmware in the driver page 1. If firmware fails to provide non-zero value, then the driver will fall back to the driver defined macro.
