2025-08-27drm/xe/configfs: Block runtime attribute changesLucas De Marchi
Although it's possible to change the attributes in runtime, they have no effect after the driver is already bound to the device. Check for that and return -EBUSY in that case. This should help users understand what's going on when the behavior is not changing even if the value from the configfs is "right", but it got to that state too late.

2025-08-27drm/amdgpu: fix shift-out-of-bounds in amdgpu_debugfs_jpeg_sched_mask_setJesse.Zhang
Fix a UBSAN shift-out-of-bounds warning in amdgpu_debugfs_jpeg_sched_mask_set when the shift exponent reaches or exceeds 32 bits. The issue occurred because a 32-bit integer '1' was being shifted by up to 32 bits, which is undefined behavior. Replace '1' with '1ULL' to ensure 64-bit arithmetic, matching the u64 type of 'val' and preventing the shift overflow. This is consistent with the existing mask calculation that already uses 1ULL. The error manifested as: UBSAN: shift-out-of-bounds in drivers/gpu/drm/amd/amdgpu/amdgpu_jpeg.c:373:17 shift exponent 32 is too large for 32-bit type 'int' v2: remove debug log Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> Suggested-by: Lijo Lazar <lijo.lazar@amd.com> Signed-off-by: Jesse Zhang <Jesse.Zhang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2025-08-27drm/amd/display: Support HW cursor 180 rot for any number of pipe splitsIvan Lipski
[Why] For the HW cursor, its current position in the pipe_ctx->stream struct is not affected by the 180 rotation, i. e. the top left corner is still at 0,0. However, the DPP & HUBP set_cursor_position functions require rotated position. The current approach is hard-coded for ODM 2:1, thus it's failing for ODM 4:1, resulting in a double cursor. [How] Instead of calculating the new cursor position relatively to the viewports, we calculate it using a viewavable clip_rect of each plane. The clip_rects are first offset and scaled to the same space as the src_rect, i. e. Stream space -> Plane space. In case of a pipe split, which divides the plane into 2 or more viewports, the clip_rect is the union of all the viewports of the given plane. With the assumption that the viewports in HUBP's set_cursor_position are in the Plane space as well, it should produce a correct cursor position for any number of pipe splits.

2025-08-27drm/amd/display: Remove redundant header filesLiao Yuanhong
The header file "dc_stream.h" is already included on line 1507. Remove the redundant include. This is because the header file was initially included towards the latter part of the code. Subsequent commits had to include the header file again earlier in the code. In my opinion, this doesn't count as a fix; it just requires removing the redundant header inclusion.
