Subject: perf trace cannot work with software events ?
Date: Sat, 26 Mar 2011 16:04:28 +0800 [thread overview]
Message-ID: <AANLkTi=pRKpdupEcXS0FmOA-PiAiXHWPYwWxN4F27fFC@mail.gmail.com> (raw)
Hi, I want to trace page faults in my program. The result I wanted like this:
1st page fault at addrA.
2nd page fault at addrB.
3rd page fault at addrC
...
Perf seems providing this function, but I can't get what I want.
I use Perf on Fedora 14(kernel 2.6.35). The following is what I have
done in my machine.
Thanks for help in advance.
[root@localhost lab]# perf record -R -c 1 -d -e faults ./hello
hello,world
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.010 MB perf.data (~418 samples) ]
[root@localhost lab]# perf trace
Fatal: no event_list!
