drm/amd/display: fix the ability to use lower resolution modes on eDP 2023-09-20T21:28:34+00:00 Hamza Mahfooz hamza.mahfooz@amd.com 2023-09-13T18:48:08+00:00 2de19022c5d7ff519dd5b9690f7713267bd1abfe On eDP we can receive invalid modes from dm_update_crtc_state() for entirely new streams for which drm_mode_set_crtcinfo() shouldn't be called on. So, instead of calling drm_mode_set_crtcinfo() from within create_stream_for_sink() we can instead call it from amdgpu_dm_connector_mode_valid(). Since, we are guaranteed to only call drm_mode_set_crtcinfo() for valid modes from that function (invalid modes are rejected by that callback) and that is the only user of create_validate_stream_for_sink() that we need to call drm_mode_set_crtcinfo() for (as before commit cb841d27b876 ("drm/amd/display: Always pass connector_state to stream validation"), that is the only place where create_validate_stream_for_sink()'s dm_state was NULL).

drm/amdgpu: fix a memory leak in amdgpu_ras_feature_enable 2023-09-20T21:27:04+00:00 Cong Liu liucong2@kylinos.cn 2023-09-14T09:45:33+00:00 f387bb578d49c5bf24204810cb2721f151d3eee2 This patch fixes a memory leak in the amdgpu_ras_feature_enable() function. The leak occurs when the function sends a command to the firmware to enable or disable a RAS feature for a GFX block. If the command fails, the kfree() function is not called to free the info memory.
