Subject: error: failed mmap with 25
Date: Fri, 14 Nov 2014 17:24:53 -0500 [thread overview]
Message-ID: <CAP3VVE0gVpfPypBvQto8r4rad-Na1Py_V5UoieZroNDATE0w4w@mail.gmail.com> (raw)
Hello,
I am trying to use perf in one ARM board. The Linux kernel is 3.8.
When I used the following command, error happens:
$ perf record -c 100000 -e '{instructions,cache-misses}:S' ./nonloop 1000
failed to mmap with 25 (Inappropriate ioctl for device)
nonloop: Terminated
Could anyone tell me how to fix the problem? Thanks in advance.
Regards,
wm
