|CGroups - add_tid_to_cgroup failed to write||John Tapsell||10/4/12 11:46 AM|
I've enabled cgroups on my android system, and now get lots of errors like:
W/SchedPolicy( 195): add_tid_to_cgroup failed to write '432'
(Permission denied); background=0
(For both background=0 and background=1, and for many different pids).
I can't understand why I get this error though.
If I do "su app_20" (for example), then echo 432 > /dev/cpuctl/tasks
then this does not give any errors (although it's not added to the
I can't understand why I would be getting permission denied. The mode
of /dev/cpuctl/tasks is 0777:
-rwxrwxrwx system system 0 2000-01-01 13:21 tasks
Any ideas please?
