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.

edp_pr_get_state() incorrectly casts a uint64_t * to uint32_t * when calling dc_wake_and_execute_gpint(). The GPINT path writes only 32 bits, leaving the upper 32 bits of the u64 output uninitialized. Replace the cast with a u32 temporary and copy the result into the u64 pointer.

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>

2025-12-16dmaengine: sh: rz-dmac: Fix rz_dmac_terminate_all()Biju Das
After audio full duplex testing, playing the recorded file contains a few playback frames from the previous time. The rz_dmac_terminate_all() does not reset all the hardware descriptors queued previously, leading to the wrong descriptor being picked up during the next DMA transfer. Fix the above issue by resetting all the descriptor headers for a channel in rz_dmac_terminate_all() as rz_dmac_lmdesc_recycle() points to the proper descriptor header filled by the rz_dmac_prepare_descs_for_slave_sg().

2025-12-16dmaengine: stm32-dma3: introduce ddata2dev helperAmelie Delaunay
The purpose of this helper is to 'standardize' device pointer retrieval, similar to the chan2dev() helper. ddata2dev() helper returns the device pointer from struct dma_device stored in stm32_dma3_ddata structure. Device pointer from struct dma_device has been initialized with &pdev->dev, so the ddata2dev helper returns &pdev->dev.

2025-12-16dmaengine: stm32-dma3: restore channel semaphore status after suspendAmelie Delaunay
Depending on the power state reached during suspend, the CxSEMCR register could have been reset, and the semaphore released. On resume, try to take the semaphore again. If the semaphore cannot be taken, an error log displaying the channel number and channel user is generated. This requires introducing two new functions: stm32_dma3_pm_suspend(), where the status of each channel is checked because suspension is not allowed if a channel is still running; stm32_dma3_pm_resume(), where the channel semaphore is restored if it was taken before suspend.
