Switched to C-style comments for consistency Signed-off-by: Haiyi Zhou Reviewed-by: Reza Amini Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher

drm/amd/display: Fix 300Hz Freesync bug

2020-01-16T18:41:33Z

Needed to reprogram vblank_start in dml properly in order to get the correct dlg params to program VTG. Signed-off-by: Alvin Lee Reviewed-by: Martin Leung Acked-by: Harry Wentland Acked-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

drm/amd/display: Clear state after exiting fixed active VRR state

2020-01-16T18:41:15Z

[why] Upon exiting a fixed active VRR state, the state isn't cleared. This leads to the variable VRR range to be calculated incorrectly. [how] Set fixed active state to false when updating vrr params Signed-off-by: Amanda Liu Reviewed-by: Anthony Koo Acked-by: Harry Wentland Acked-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

drm/amd/display: Reinstate LFC optimization

2019-12-18T21:09:08Z

[why] We want to streamline the calculations made when entering LFC. Previously, the optimizations led to screen tearing and were backed out to unblock development. [how] Integrate other calculations parameters, as well as screen tearing, fixes with the original LFC calculation optimizations.

drm/amd/display: Fix screen tearing on vrr tests

2019-12-05T21:32:11Z

[Why] Screen tearing is present in tests when setting the frame rate to certain fps [How] Revert previous optimizations for low frame rates. Signed-off-by: Amanda Liu Reviewed-by: Aric Cyr Acked-by: Leo Li Signed-off-by: Alex Deucher

drm/amd/display: remove redundant assignment to variable v_total

2019-12-02T22:55:08Z

The variable v_total is being initialized with a value that is never read and it is being updated later with a new value. The initialization is redundant and can be removed. Addresses-Coverity: ("Unused value") Signed-off-by: Colin Ian King Signed-off-by: Alex Deucher

drm/amd/display: Add capability check for static ramp calc

2019-10-11T00:34:20Z

[Why] Static ramp to max refresh rate does not have capability check on calculated v_total. Programming a lower v_total_min and max than the total causes continuous spurious HPDs. [How] Add a capability check after v_total calculation similar to calculate v_total helper functions.

drm/amd/display: Properly round nominal frequency for SPD

2019-10-11T00:32:16Z

[Why] Some displays rely on the SPD verticle frequency maximum value. Must round the calculated refresh rate to the nearest integer. [How] Round the nominal calculated refresh rate to the nearest whole integer. Signed-off-by: Aric Cyr Reviewed-by: Anthony Koo Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher

drm/amd/display: Improve LFC behaviour

2019-10-03T14:10:58Z

[Why] There can be some unsynchronized frames when entering/exiting LFC. This may cause tearing or stuttering at such transitions. [How] Add a enter/exit margin to algorithm to smoothly transition into and out of LFC without desynchronizing frames.
