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 report -n
