Hi, In this series, I'm not equalizing watermarks among planes of all CRTC's, these patches equalizing it only among Planes of single CRTC from DDB pool allocated for that CRTC, which doesn't require wait_for_vblank So it'll not affect the FPS. On Wednesday 31 August 2016 07:08 PM, Maarten Lan

[Intel-gfx] [PATCH 4/7] drm/i915/skl: New ddb allocation algorithm

2016-08-29 Thread Kumar, Mahesh
This patch implements new DDB allocation algorithm as per HW team suggestion. This algo takecare of scenario where we allocate less DDB for the planes with lower relative pixel rate, but they require more DDB to work. It also takes care of enabling same watermark level for each plane, for efficient
