Sorry for delayed response but i just find some free time, do you
still want me to test mainline + "parent-runs first" patch or will i
drop that one and test v2 which can change default behaviour?
i suspect for now it would be sufficient if you could check the v2
patch.
if it _works_, please try this:
echo 0 > /proc/sys/kernel/sched_child_runs_first
this should break Kaffeine again :)
(if it doesnt work then the Kaffeine problem is unrelated to
child-runs-first.)
OK, i tested both plain -rc7 and -rc7 + CFSv2 with while
sched_child_runs_first enabled/disabled.
I'm always using same video file and try to reproduce freeze with constantly
pressing forward/backward buttons. With CFS 2-3 forward/backward attempt
reproduces this behaviour.
And here are the results.
Mainline still has no issues with both xine-lib/kaffeine and xine-ui
(kaffeine-0.8.4, xine-lib-1.1.5 [both xcb enabled], xine-ui-0.99.4). I really
try hard to reproduce the freeze, but i can't...
And CFSv2 still fails for both child_runs_first and parent_runs_first cases
with same strace output (FUTEX_WAIT).
I have the same problem here ( same packages ).
Even VLC if I go forward/backward and then play again its start to
ramdom freeze here but only for 1 - 2 seconds maybe.
If you want me to test something else just ask please :)
Cheers
