2025-12-16drm/amdgpu: fix a job->pasid access race in gpu recoveryAlex Deucher
Avoid a possible UAF in GPU recovery due to a race between the sched timeout callback and the tdr work queue. The gpu recovery function calls drm_sched_stop() and later drm_sched_start(). drm_sched_start() restarts the tdr queue which will eventually free the job. If the tdr queue frees the job before time out callback completes, the job will be freed and we'll get a UAF when accessing the pasid. Cache it early to avoid the UAF.

[WHY] User may connect mst dock with multi monitors and do quick unplug and plug in one of the monitor. This operatioin may create CSN from dock to display driver. Then display driver would disable and then enable mst link and also disable/enable DPCD mst_en bit in dock RX. However, when mst_en bit being disabled, if dock has another CSN message to transmit then the message would be removed because of the disabling of mst_en. In this case, the message is missing and it ends up no display in the replugged monitor. [HOW] Don't disable mst_en bit when link still has sink connected.

It tries to initialize the state to zero at the start but that's not going to work because of the type mismatch. It suggests that callers are allowed to pass uninitialized data to edp_pr_get_state() but at present there are no callers so this is only a bug in the code but doesn't affect runtime. 1461 // Return invalid state when GPINT times out 1462 *state = PR_STATE_INVALID; 1463 } Fixes: 74ce00932e7e ("drm/amd/display: Refactor panel replay set dmub cmd flow") Reported by: Dan Carpenter <dan.carpenter@linaro.org> Cc: Robin Chen <robin.chen@amd.com> Cc: Jack Chang <jack.chang@amd.com> Cc: Leon Huang <Leon.Huang1@amd.com> Cc: Alex Hung <alex.hung@amd.com> Cc: Aurabindo Pillai <aurabindo.pillai@amd.com> Cc: Roman Li <roman.li@amd.com> Cc: Harry Wentland <harry.wentland@amd.com> Cc: Tom Chung <chiahsuan.chung@amd.com> Signed-off-by: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com> Reviewed-by: Aurabindo Pillai <aurabindo.pillai@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2025-12-10drm/amd: Fix unbind/rebind for VCN 4.0.5Mario Limonciello (AMD)
Unbinding amdgpu has no problems, but binding it again leads to an error of sysfs file already existing. This is because it wasn't actually cleaned up on unbind. Add the missing cleanup step.

2025-12-10drm/amdgpu: Update MES VM_CNTX_CNTL for XNACK off for GFX 12.1Mukul Joshi
Currently, we do not turn off retry faults in VM_CONTEXT_CNTL value when passing it to MES if XNACK is off. This creates a situation where XNACK is disabled in SQ but enabled in UTCL2, which is not recommended. As a result, turn off/on retry faults in both SQ and UTCL2 when passing vm_context_cntl value to MES if XNACK is disabled/enabled.
