 |
|
I try to setup a rtaudio cgroup with the following config:
| Code: | # cat cgconfig.conf
group rtaudio {
perm {
task {
uid = root;
gid = audio;
}
admin {
uid = root;
gid = root;
}
}
cpu {
cpu.rt_runtime_us = 950000;
}
}
|
| Code: | # cat cgrules.conf
# comments here
@audio:jackd cpu rtaudio/
|
In the kernel config, I have (kernel 3.0.4-gentoo):
| Code: | # cat .config|grep GROUP
CONFIG_CGROUPS=y
# CONFIG_CGROUP_DEBUG is not set
CONFIG_CGROUP_FREEZER=y
CONFIG_CGROUP_DEVICE=y
CONFIG_CGROUP_CPUACCT=y
# CONFIG_CGROUP_MEM_RES_CTLR is not set
# CONFIG_CGROUP_PERF is not set
CONFIG_CGROUP_SCHED=y
CONFIG_FAIR_GROUP_SCHED=y
CONFIG_RT_GROUP_SCHED=y
CONFIG_BLK_CGROUP=m
# CONFIG_DEBUG_BLK_CGROUP is not set
CONFIG_SCHED_AUTOGROUP=y
# CONFIG_CFQ_GROUP_IOSCHED is not set
|
When starting cgconfig:
| Code: | # /etc/init.d/cgconfig start
* Starting cgconfig service ...
* Failed to parse /etc/cgroup/cgconfig.conf [ !! ]
* ERROR: cgconfig failed to start |
With cgconfigparser:
| Code: | # cgconfigparser -l /etc/cgroup/cgconfig.conf
Adding controller cpu
[1] name value pair being processed is cpu.rt_runtime_us=950000
Loading configuration file /etc/cgroup/cgconfig.conf failed
Cannot have mount and namespace keyword in the same configuration file |
I took my config from http://trac.jackaudio.org/wiki/Cgroups
I don't understand if it is a bug in libcgroup, in my cgroup config, or in my kernel config.
Any help would be appreciated.
EDIT:
I found the solution. It was just to add the namespace stuff as in Method 2.5 on the JACK wiki.
