Another update:
This is the same testing but for cfs-v7.
Summary:
1. context switch rate is much higher than for cfs-v6 for the same
sched_granularity_ns 20
2. Video playback suffered. FPS is much lower.
3. Trying different values of sched-granularity_ns didn't help
(neither did the default)
so SD context-switched twice as much and saturated the CPU fully, while
under cfs-v6 there was 34% idle time left. That double context-switch
rate and higher CPU utilization could easily result in you experiencing
a 'smoother' desktop (and smoother video playback) on SD.
could you try to maximize
.
Under SD i haven't seen anything get starved.
mainline surprisingly works better than i expected, but beryl suffers
and responsiveness suffers under load.

First of all, thank you for your continued development of SD. I've
