how does it behave without the cfs patch applied? Does it work better
under v20.5? The best debug output for me to look at would be to
download these two scripts:
http://people.redhat.com/mingo/cfs-scheduler/tools/cfs-debug-info.shhttp://people.redhat.com/mingo/cfs-scheduler/tools/cfs-debug-info-clear.sh
first run cfs-debug-info-clear.sh, then use the system for a few minutes
and make sure apps are behaving in a 'stutter-free' way. Then run
cfs-debug-info.sh (still no glxgears running) - it will produce a "no
load" debug info file. Then start the 9x glxgears instances, reproduce
the "stuttering" behavior in the apps, and run cfs-debug-info.sh - this
will produce a second "under load" output file. Please send me both
output files.
also, what's the output of "glxgears -info" - does it render on real 3D
hardware, or uses the sw-mesa fallback?
