>
> This is a reland of I7946d7acab334bffdf2bb49a1d9c424cf46fc610 and
> the following bug fixes as follows;
> "viz: Fix wrong uv_rect calculation" 4bf9d01d
> "viz: add unittests for CL:1291590" f8dfbe74
>
> Additional fix:
> - Fix the flickering issue because of primary |uv_rect| cropping even though
> an overlay attemption fails mainly due to limited pixel rate (e.g. 4k video).
> - Fix wrong |uv_rect| calculation which causes atomic page flip failures with
> "No space left on device (28)" error.

> Original change's description:
> > viz: Turn off or crop primary plane when possible

> > For many fullscreen cases, the rest of the renderpass quads are solid
> > black quads. In that case, we can turn off the primary plane, and not
> > having to scan out an full screen of black pixels saves a good deal of
> > power. In other cases, we can crop down the primary plane down to the
> > content rectangle (youtube channel logo, for example) and save power.

> > Averaging battery draw measurement over about a minute of play back
> > for a fullscreen youtube video, power savings for soraka is around
> > 500mW (6.5W to 6.0W) and 300mW for kevin (4.4W to 4.1W), when we
> > turn off the primary plane.
