drm/amd/display: Remove last parts of timing_trace

2024-11-04T16:26:36Z

Commit c2c2ce1e9623 ("drm/amd/display: Optimize passive update planes.") removed the last caller of context_timing_trace. Remove it. With that gone, no one is now looking at the 'timing_trace' flag, remove it and all the places that set it. Signed-off-by: Dr. David Alan Gilbert Signed-off-by: Alex Deucher

drm/amd/display: Add hpd_source index out-of-bounds check for dcn3x link encoder creation

2024-10-15T15:21:22Z

This patch adds a boundary check for the hpd_source index during the link encoder creation process for dcn3x IP's. The check ensures that the index is within the valid range of the link_enc_hpd_regs array to prevent out-of-bounds access.

drm/amd/display: Implement bounds check for stream encoder creation in DCN301

2024-02-07T23:30:04Z

'stream_enc_regs' array is an array of dcn10_stream_enc_registers structures. The array is initialized with four elements, corresponding to the four calls to stream_enc_regs() in the array initializer. This means that valid indices for this array are 0, 1, 2, and 3. The error message 'stream_enc_regs' 4 <= 5 below, is indicating that there is an attempt to access this array with an index of 5, which is out of bounds. This could lead to undefined behavior Here, eng_id is used as an index to access the stream_enc_regs array. If eng_id is 5, this would result in an out-of-bounds access on the stream_enc_regs array. Thus fixing Buffer overflow error in dcn301_stream_encoder_create reported by Smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/resource/dcn301/dcn301_resource.c:1011 dcn301_stream_encoder_create() error: buffer overflow 'stream_enc_regs' 4 <= 5 Fixes: 3a83e4e64bb1 ("drm/amd/display: Add dcn3.01 support to DC (v2)") Cc: Roman Li Cc: Rodrigo Siqueira Cc: Aurabindo Pillai Signed-off-by: Srinivasan Shanmugam Reviewed-by: Roman Li Signed-off-by: Alex Deucher

drm/amd/display: Refactor resource into component directory

2023-11-17T14:30:50Z

[WHY] Move all resource files to unique folder resource. [HOW] Created resource folder in dc, moved the dcnxx_resource.c and dcnxx_resource.h files into corresponding new folders inside the resource and made appropriate changes for compilation in Makefiles.
