2018-07-25T09:26:09Z

commit 5292221d6ddfed75e5b46cd42237a677094b99f3 upstream. This reverts commit 018d82e5f02ef3583411bcaa4e00c69786f46f19. This breaks DDC in certain cases. Revert for 4.18 and previous kernels. For 4.19, this is fixed with the following more extensive patches: drm/amd/display: Serialize is_dp_sink_present drm/amd/display: Break out function to simply read aux reply drm/amd/display: Return aux replies directly to DRM drm/amd/display: Right shift AUX reply value sooner than later drm/amd/display: Read AUX channel even if only status byte is returned Link: https://lists.freedesktop.org/archives/amd-gfx/2018-July/023788.html Acked-by: Harry Wentland Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org Signed-off-by: Greg Kroah-Hartman

drm/amd/display: use HW hdr mult for brightness boost

2018-03-14T20:08:46Z

In MPO scenario when playing SDR clip in HDR desktop mode, Win is boosting desktop and requests driver to boost MPO. But driver boosting is currently done in regamma which is stream property and thus shared between grph and video. Redesigning the boosting in RV: use CM_HDR_MULT register which was added for this scenario. It also has the benefit that it can be done in HIRQL.

drm/amd/display: make dm_dp_aux_transfer return payload bytes instead of size

2018-02-28T20:38:40Z

The drm layer expects aux->transfer() to return the payload bytes read. Currently dm_dp_aux_transfer() returns the payload size which does not gets updated during the read, hence not giving the right data for the drm layer to pars edid. This leads to the drm layer to conclude as the edid is BAD and hence some monitors/devices dont get detected properly. This patch changes the return type of dm_dp_aux_transfer() to actual bytes read during DP_AUX_NATIVE_READ & DP_AUX_I2C_READ.
