drm/amd/display: fix bug of accessing invalid memory

2018-10-15T21:17:17Z

[Why] A loop inside of build_evenly_distributed_points function that traverse through the array of points become an infinite loop when m_GammaUpdates does not get assigned to any value. [How] In DMColor, clear m_gammaIsValid bit just before writting all Zeromem for m_GammaUpdates, to prevent calling build_evenly_distributed_points before m_GammaUpdates gets assigned to some value.

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.
