Hi,
Have you guys ever saw this:
[root@perf4 ~]# perf list <SKIP> mem:<addr>[:access] [Hardware breakpoint]
[ Tracepoints not available: Success ] [root@perf4 ~]# uname -r 4.1.0-rc8 [root@perf4 ~]# mount | grep tracefs tracefs on /sys/kernel/debug/tracing type tracefs (rw,relatime) [root@perf4 ~]# mount | grep debugfs debugfs on /sys/kernel/debug type debugfs (rw,relatime,seclabel) [root@perf4 ~]#
[root@zoo ~]# ls -la /sys/kernel/debug/tracing/events/ | tail drwxr-xr-x. 15 root root 0 Jun 17 10:47 timer drwxr-xr-x. 3 root root 0 Jun 17 10:47 tlb drwxr-xr-x. 3 root root 0 Jun 17 10:47 udp drwxr-xr-x. 4 root root 0 Jun 17 10:47 v4l2 drwxr-xr-x. 17 root root 0 Jun 17 10:47 vmscan drwxr-xr-x. 3 root root 0 Jun 17 10:47 vsyscall drwxr-xr-x. 6 root root 0 Jun 17 10:47 workqueue drwxr-xr-x. 31 root root 0 Jun 17 10:47 writeback drwxr-xr-x. 37 root root 0 Jun 17 10:47 xen drwxr-xr-x. 11 root root 0 Jun 17 10:47 xhci-hcd [root@zoo ~]#
