oprofile seems working correctly on the efika. You might try to use it.
thanks for the tip, Luca!
after building a profiling-enabled 18.104.22.168.3 kernel, the oprofile specialized driver, and oprofile itself (with kernel support enabled, naturally), i can now run oprofile sessions. alas, my testbed app developed one peculiar problem since then..
everything loads up and runs fine to the first swapBuffers or thereabout, where it appears to get stuck. after a while the kernel announces that the app has been blocked for 120s, and things go downhill from there.
the truly peculiar part is that the above happens even outside of oprofile sessions.
same thing happens to /usr/bin/simple_draw - judging by its log messages it does not get to complete its first frame either.
so here comes the mandatory question: has anybody successfully run an EGL/ES app under oprofile and/or a profile-enabled kernel on EfikaMX? needless to say, guidelines and tips from successful scenarios are welcome.
