Harry Wentland e47f1691ad drm/amd/display: Don't restrict bpc to 8 bpc ... This will let us pass the kms_hdr.bpc_switch IGT test. The reason the bpc restriction was required is historical. At one point in time we were not falling back to a lower bpc when we didn't have enough bandwidth for the maximum bpc reported by a display. This meant that we couldn't enable some high refresh modes unless we limitted the bpc. Starting with this patch the issue is fixed: commit cbd14ae7ea ("drm/amd/display: Fix incorrectly pruned modes with deep color") This patch implemented a fallback mechanism if mode validation failed at the max bpc. This means users now automatically get all modes that can be supported by at least 6 bpc. The driver will enable the mode with the highest possible bpc that is supported by the display. v2: - explain why this is no longer needed (Michel) - refer to commit that fixed bpc fallback (Michel) Signed-off-by: Harry Wentland <harry.wentland@amd.com> Cc: Pekka Paalanen <ppaalanen@gmail.com> Cc: Sebastian Wick <sebastian.wick@redhat.com> Cc: Vitaly.Prosyak@amd.com Cc: Joshua Ashton <joshua@froggi.es> Cc: dri-devel@lists.freedesktop.org Cc: amd-gfx@lists.freedesktop.org Cc: Michel Dänzer <michel.daenzer@mailbox.org> Reviewed-by: Joshua Ashton <joshua@froggi.es> Reviewed-by: Michel Dänzer <mdaenzer@redhat.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>		2023-02-28 14:28:39 -05:00
