drm/amd/display: Change default size for dummy plane in DML2

2024-04-03T13:32:26Z

[ Upstream commit 75eb8f7df65c5e6eb22a5aff8deb60ce0b65de1a ] [WHY & HOW] Currently, to map dc states into dml_display_cfg, We create a dummy plane if the stream doesn't have any planes attached to it. This dummy plane uses max addersable width height. This results in certain mode validations failing when they shouldn't.

drm/amd/display: Prevent potential buffer overflow in map_hw_resources

2024-02-27T17:20:42Z

Adds a check in the map_hw_resources function to prevent a potential buffer overflow. The function was accessing arrays using an index that could potentially be greater than the size of the arrays, leading to a buffer overflow. Adds a check to ensure that the index is within the bounds of the arrays. If the index is out of bounds, an error message is printed and break it will continue execution with just ignoring extra data early to prevent the buffer overflow. Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml2_wrapper.c:79 map_hw_resources() error: buffer overflow 'dml2->v20.scratch.dml_to_dc_pipe_mapping.disp_cfg_to_stream_id' 6 <= 7 drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml2_wrapper.c:81 map_hw_resources() error: buffer overflow 'dml2->v20.scratch.dml_to_dc_pipe_mapping.disp_cfg_to_plane_id' 6 <= 7 Fixes: 7966f319c66d ("drm/amd/display: Introduce DML2") Cc: Rodrigo Siqueira Cc: Roman Li Cc: Qingqing Zhuo Cc: Aurabindo Pillai Cc: Tom Chung Signed-off-by: Srinivasan Shanmugam Suggested-by: Roman Li Reviewed-by: Roman Li Reviewed-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

[Why] Currently there is an error while translating input clock sates into output clock states. The highest fclk setting from output sates is being dropped because of this error.
