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: 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.

Call drm_mode_connector_update_edid_property every time in .get_modes hook, due to the fact that edid property is getting removed from usermode ioctl DRM_IOCTL_MODE_GETCONNECTOR each time in hot unplug.

drm/amd/display: Don't read EDID in atomic_check

2018-04-25T15:07:50+00:00

We shouldn't attempt to read EDID in atomic_check. We really shouldn't even be modifying the connector object, or any other non-state object, but this is a start at least. Moving EDID cleanup to dm_dp_mst_connector_destroy from dm_dp_destroy_mst_connector to ensure the EDID is still available for headless mode.

drm/amd/display: Disallow enabling CRTC without primary plane with FB

2018-04-25T15:07:49+00:00

The below commit "drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2" introduces a slight behavioral change to rmfb. Instead of disabling a crtc when the primary plane is disabled, it now preserves it. Since DC is currently not equipped to handle this we need to fail such a commit, otherwise we might see a corrupted screen. This is based on Shirish's previous approach but avoids adding all planes to the new atomic state which leads to a full update in DC for any commit, and is not what we intend. Theoretically DM should be able to deal with states with fully populated planes, even for simple updates, such as cursor updates. This should still be addressed in the future.

drm/amd/display: Don't program bypass on linear regamma LUT

2018-04-19T15:19:11+00:00

Even though this is required for degamma since DCE HW only supports a couple predefined LUTs we can just program the LUT directly for regamma. This fixes dark screens which occurs when we program regamma to bypass while degamma is using srgb LUT.
