https://bugzilla.kernel.org/show_bug.cgi?id=213715 mario.limonciello@xxxxxxx changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |mario.limonciello@xxxxxxx --- Comment #2 from mario.limonciello@xxxxxxx --- I would suggest to work with BOE and CSO to fix the DPCD values in panel firmware to not report aux control if it is not functional. You can see the kernel checks the DPCD to determine whether to use AUX or PWM. https://github.com/torvalds/linux/blob/c010efb7f0bc0c3cb2cd26b000f71d4bd0c427cd/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c#L2433 BTW this behavior has been also been reported in the past, so a heuristic may be introduced at some point in the future for the buggy panel firmware: https://gitlab.freedesktop.org/drm/amd/-/issues/1438 -- You may reply to this email to add a comment.
