I also did a quick hack changing some of those values, giving non-interrputed audiostream with audioapp alone, at 0.7ms. (on a core2duo @ 2.5ghz) That is actually better than BFS. Peace Be With You. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a

The 10ms averager in fair.c

2012-09-30 Thread Uwaysi Bin Kareem
Hiya. I just had an initial look at fair.c There seems to be a 10ms averager in there? You are aware that that means you work on delayed values? Isn`t that counterintuitive to the principle of sharing? That means short bursts of cpu-use will be filtered out, and given less cpu time.

is the filtered spike, much lower, but it lasts long beyond the 100uS spike. (10ms). Why would that be used in something that should represent cpu-usage? Peace Be With You.

I have done some research on latency. I have config`d a linux kernel to run 0.3ms reliable latency with audiostreams, under normal worksituations. (An audioapp, and maybe some small tasks in between). This also resulted in an extremely smooth gameplaying experience, like an asm-programmed
