Yuxuan Shui	db6ed75b60	core: don't always delay schedule_render to vblank ... It's kind of dumb anyway. If we get damage event right after a vblank event, we would waste the whole vblank. Instead improve the frame scheduling logic to target the right vblank interval. This only affects smart_frame_pacing anyway. Signed-off-by: Yuxuan Shui <yshuiv7@gmail.com>	2023-12-19 23:27:11 +00:00
Yuxuan Shui	2e1c4e51b3	core: don't request vblank events when we are not rendering ... Previously everytime we receive a vblank event, we always request a new one. This made the logic somewhat simpler. But this generated many useless vblank events, and wasted power. We only need vblank events for two things: 1. after we rendered a frame, we need to know when it has been displayed on the screen. 2. estimating the refresh rate. This commit makes sure we only request vblank events when it's actually needed. Fixes #1079 Signed-off-by: Yuxuan Shui <yshuiv7@gmail.com>	2023-12-19 22:36:31 +00:00
Yuxuan Shui	8e1f3c92f5	core: factor out code for estimating the rendering time budget ... Add a render_statistics type to encapsulate all the statistics done on rendering times. And use that to estimate the time budget for rendering and frame pacing. Tweak the rolling window utilities a bit so we can reuse one rolling window for multiple statistics.
