drm/amd/display: refactor vupdate interrupt registration

2018-08-27T16:10:54Z

We only need to register once OS calls the interrupt control. Also, if we are entering static screen mode, disable after ramping is done. Disable shall be done via timer of 2 seconds regardless of ramping complete or not, just to simplify. Also, ramp to mid instead of min, due to better flicker performance...

drm/amd/display: fix LFC tearing at top of screen

2018-08-27T16:10:54Z

Tearing occurred because new VTOTAL MIN/MAX was being programmed too early. The flip can happen within the VUPDATE high region, and the new min/max would take effect immediately. But this means that frame is not variable anymore, and tearing would occur when the flip actually happens. The fixed insert duration should be programmed on the first VUPDATE interrupt instead.

drm/amd/display: Fix bug that causes black screen

2018-08-27T16:10:53Z

Ignore MSA bit on DP display is usually set during SetTimings, but there was a case where the module thought refresh rate was not valid and ignore MSA bit was not set. Later, a valid refresh rate range was requested but since ignore MSA bit not set, it caused black screen. Issue if with how the module checked for VRR support. Fix up that logic. DM should call new valid_range function to determine if timing is supported. Signed-off-by: Anthony Koo Reviewed-by: Aric Cyr Acked-by: Harry Wentland Signed-off-by: Alex Deucher
