This series adds experimental fault injection to the UFS device model
so host drivers can exercise task abort and power management recovery,
updates the task management description in the UFS docs, and adds
qtest cases for controller reset, MCQ runtime registers, task
management and fault-injected task abort.
The series applies on top of Daejun Park's Zoned UFS v3 series.
- Patches 1-2: x-fault-inject-tag and x-fault-inject-mode properties
to hold a transfer request, and task management handling for the
held request.
- Patch 3: ssu-timeout mode for power management recovery testing.
- Patch 4: document the supported task management functions (QUERY
TASK and ABORT TASK).
- Patches 5-8: qtest helpers and test cases.
The fault injection properties are experimental (x- prefix) and off
by default.
Differences from v1:
- Rebased on top of Daejun Park's Zoned UFS v3 series.
- Clarified in patch 2 that in-transition mode completes without
executing the SCSI command or transferring data.
v1: https://lore.kernel.org/qemu-devel/20261015060827.341298-1-stanleyjhu@google.com/
Tested with qos-test on aarch64 (all 28 UFS cases pass, including 10
zoned UFS cases).
