[Intel-gfx] [RFC 1/2] drm/i915: Indicate integer up-scaling ratios

2019-09-03 Thread Shashank Sharma
If the upscaling ratio is a complete integer, Intel display HW can pickup special scaling mode, which can produce better non-blurry outputs. This patch adds a check to indicate if this is such an upscaling opportunity, while calculating the scaler config, and stores it into scaler state. Cc: Jani
