Jakob Bornecrantz ad4c6a7215 u/pacing: More Tracy plots 2022-11-24 15:34:59 +00:00
Jakob Bornecrantz d1db1dabfd u/pacing: Work around asserts on slow compositors 
This isn't the most ideal solution but a proper fix will take longer.

Jakob Bornecrantz 7b1c18255a u/pacing: Work around issues with frame reuse 
The code creates a frame with the timing information, and keeps track of the
times the applications does various things during the frame loop. Like
starting to render and finished rendering and so on. It keeps track of that
frame until it has determined that the application or the system compositor
will never do anything thing with that frame.

Now the allocation side of thing is very simple, just a long array of
FRAME_COUNT size that is reused with frame_id % FRAME_COUNT. So if the
application or the compositor keeps a frame along for too long it will try to
reuse that frame. The code has asserts to catch this. Making FRAME_COUNT makes
that re-use more unlikely.

All at least visually inspected, some revised from the auto-fixit

Connor Smith 703baa94fe Make app pacing more robust to variable composition->display times. 
If the last returned display time shifts backwards slightly with respect to the
last sampled display time from the compositor, the next predicted display time
will not move forward by one frame. Adding half the display period to the
comparison makes the pacing robust to this case.

Ryan Pavlik 9b6d117970 a/util: Some reorg and renaming in upa to be closer to upc 2022-02-08 10:51:40 -06:00
Ryan Pavlik a2e1eb7e75 a/util: Have all timestamps be injected into pacing. 
No more calling os_monotonic_get_ns() inside the pacing helpers.
Much better testability.

Ryan Pavlik a7c22fd185 a/util: Rename u_render_timing to u_pacing_app and u_frame_timing to u_pacing_compositor. 
They both control pacing, but for different uses. Neither actually performs any timing.
