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. 11 root root 0 Jun 17 10:47 xhci-hcd
[root@zoo ~]#

Just a heads up, will continue investigating after some food...

Running the older perf that ignores tracepoints not on the debugfs
system?

Right, I thought I was, but there was a perf-3.10...rpm installed that
was being used instead of my ~/bin/perf new binary, removed the rpm and
it lists the tracepoints now, should've used 'perf --version' before
hitting the send button, sorry about that.
