Hello All,
I am trying to use perf tool. I have installed ubuntu 12.04 on Pandaboard.
After booting up the system, installed linux-tools. Which installed
linux-tools-3.0.0-25. running the perf, gives following error.
perf_3.0.0-25 stat ls
Error: open_counter returned with 19 (No such device). /bin/dmesg may
provide additional information.
Fatal: Not all events could be opened.
How do I fix the above problem? Did anyone get the perf to work on any
ubuntu releases on Pandaboard? I can use any build if perf and cpufreq are
available.
I have actually tried various builds.(11.04,11.10, 12.04 and 12.10 alpha).
However, I couldn't get perf tool to work in any of these builds with the
above steps.
This issue is actually blocking my research. Any help is appreciated.
Thank you
