Subject: perf record: mmap fails when specifying process/thread
Date: Wed, 16 Feb 2011 08:43:45 -0700 [thread overview]
Message-ID: <4D5BF0B1.7080602@gmail.com> (raw)
Latest perf-core (pulled 5 minutes ago):
# ps -C sshd
PID TTY TIME CMD
961 ? 00:00:00 sshd
1042 ? 00:00:00 sshd
# /tmp/build-perf/perf record -v -fo/tmp/perf.data -p 1042
Warning: ... trying to fall back to cpu-clock-ticks
Fatal: failed to mmap with 22 (Invalid argument)
It works fine with -a argument and when a command is given, but fails
with the -p or -t argument.
