Hello
so I'm running 4.1-rc4 on my Haswell machine and a lot of my perf_event
testsuite is failing. There seems to be weird event scheduling issues.
I can reproduce it with plain perf; simple event groups that should work
fine can't be scheduled.
vince@haswell:~$ perf stat -e \{cycles,instructions\} sleep 1
Performance counter stats for 'sleep 1':
<not counted> cycles
<not counted> instructions
1.003414661 seconds time elapsed
I just wanted to check to see if this was a known problem before I started
bisecting. I was also possibly seeing this with 4.1-rc2.
Vince
