drm/amd/display: Update color props when modeset is required

2018-05-31T18:08:26+00:00

This fixes issues where color management properties don't persist over DPMS on/off, or when the CRTC is moved across connectors. Signed-off-by: Leo (Sunpeng) Li Reviewed-by: Harry Wentland Cc: stable@vger.kernel.org Signed-off-by: Alex Deucher

drm/amd/display: Make atomic-check validate underscan changes

2018-05-31T18:08:22+00:00

When the underscan state was changed, atomic-check was triggering a validation but passing the old underscan values. This change adds a somewhat hacky check in dm_update_crtcs_state that will update the stream if old and newunderscan values are different. This was causing 4k on Fiji to allow underscan when it wasn't permitted.

drm/amd/display: Fix BUG_ON during CRTC atomic check update

2018-05-29T19:22:28+00:00

For cases where the CRTC is inactive (DPMS off), where a modeset is not required, yet the CRTC is still in the atomic state, we should not attempt to update anything on it. Previously, we were relying on the modereset_required() helper to check the above condition. However, the function returns false immediately if a modeset is not required, ignoring the CRTC's enable/active state flags. The correct way to filter is by looking at these flags instead.

drm/amd/display: Use kvzalloc for potentially large allocations

2018-05-09T20:16:13+00:00

Allocating up to 32 physically contiguous pages can easily fail (and has failed for me), and isn't necessary anyway. Reviewed-by: Harry Wentland Signed-off-by: Michel Dänzer Signed-off-by: Alex Deucher

drm/amd/display: Check dc_sink every time in MST hotplug

2018-04-25T15:08:09+00:00

Extended fix to: "Don't read EDID in atomic_check" Fix issue of missing dc_sink in .mode_valid in hot plug routine. Need to check dc_sink everytime in .get_modes hook after checking edid, since edid is not getting removed in hot unplug but dc_sink doesn't.
