Null pointer dereference issue could occur when pipe_ctx->plane_state is null. The fix adds a check to ensure 'pipe_ctx->plane_state' is not null before accessing.

2025-03-05drm/amdkfd: implement per queue sdma reset for gfx 9.4+Jonathan Kim12-25/+171
To reset hung SDMA queues on GFX 9.4+ for the GFX9 family, a soft reset must be issued through SMU. Since soft resets will reset an entire SDMA engine, use a common KGD call to do the reset as the KGD will handle avoiding a reset of in flight GFX and paging queues on that engine. In addition, create a common call for all reset types to simplify the handling of module parameter settings that block gpu resets.

2025-03-05drm/amdgpu: Add support for CPERs on virtualizationTony Yi5-13/+195
Add support for CPERs on VFs. VFs do not receive PMFW messages directly; as such, they need to query them from the host. To avoid hitting host event guard, CPER queries need to be rate limited. CPER queries share the same RAS telemetry buffer as error count query, so a mutex protecting the shared buffer was added as well. For readability, the amdgpu_detect_virtualization was refactored into multiple individual functions.

For vcn_v_5_0_1, set power state to gating during hw fini. Also there may be scenario where VCN engine hangs during a job execution, then it's not safe to assume that set_pg_state works fine during hw_fini to put the state to gated. After a reset, we can assume that it's in the default state, therefore reset the driver maintained state. Put the default state as gated during reset as per this assumption.
