i am trying to do some profiling with perf (2.6.31.4). while
thread-level profiling works fine, i haven't been able to record
profiling data of a whole process (i.e. main thread + child threads).
from my understanding, this should be enabled by running 'perf record
-i' on the main thread. this does only collect the data from the main
thread, though.

is this an issue with perf or with my understanding of perf?

thanks, tim
