58-t::
59--tid=::
60 Record events on existing thread ID (comma separated list).
61
62-u::
63--uid=::
64 Record events in threads owned by uid. Name or number.
65
66-G::
67--cgroup::
68 Record events in threads in a cgroup.
69
70 Look for cgroups to set at the /sys/fs/cgroup/perf_event directory, then
71 remove the /sys/fs/cgroup/perf_event/ part and try:
72
73 perf trace -G A -e sched:*switch
74
75 Will set all raw_syscalls:sys_{enter,exit}, pgfault, vfs_getname, etc
76 _and_ sched:sched_switch to the 'A' cgroup, while:
77
78 perf trace -e sched:*switch -G A
79
80 will only set the sched:sched_switch event to the 'A' cgroup, all the
81 other events (raw_syscalls:sys_{enter,exit}, etc are left "without"
82 a cgroup (on the root cgroup, sys wide, etc).
83
84 Multiple cgroups:
85
86 perf trace -G A -e sched:*switch -G B
87
88 the syscall ones go to the 'A' cgroup, the sched:sched_switch goes
89 to the 'B' cgroup.
90
66--filter-pids=::
