Hi,
I'm doing some work with audio and have noticed some problems with the
ULE scheduler. I have a program that generate audio based on
key-presses. When no keys are pressed, the load is near 0%, but as soon
as you start pressing keys, the load goes maybe to 80% of a CPU core.
This program I run with rtprio 8 xxx. The issue I observe or hear
actually, is that it takes too long until the scheduler grasps that this
program needs it's own CPU core and stops time-sharing the program. When
I however use cpuset -l xxx rtprio 8 yyy everything is good, and the
program outputs realtime audio in-time.
Or is this perhaps a CPU frequency stepping issue?
Any advice on where to look?
