I am trying to use perf in a system with 3.8 linux kernel. When I used the following command, error happens:
$ perf record -c 100000 -e '{cycles,instructions}:S' ./nonloop 1000
failed to mmap with 25 (Inappropriate ioctl for device)
nonloop: Terminated
Could anyone tell me how to solve the problem?
Looks like :S is the problem.
perf record -c 100000 -ecycles,instructions ./somebin
runs fine. What is :S ?
I'm seeing a similar error running:
sudo perf record -esyscalls:sys_enter -p $(pidof some_bin) failed to mmap with 22 (Invalid argument)
where perf list suggests syscalls:sys_enter should be available.
