Public bug reported:
I have recorded system activity with
sudo perf record -a --call-graph=dwarf -e sched:sched_process_exec
-e cycles -o perf.steam-validating.data
but when I try to load it with
sudo perf report --hierarchy -i perf.steam-validating.data
I get error message
unwind: target platform=x86 is not supported
even though I have both 32-bit and 64-bit unwind support installed as
far as I know:
$ aptitude search "~i libunwind"
i A android-libunwind - libunwind for Android
i A libunwind-dev - library to determine the call-chain
of a program
i libunwind-dev:i386 - library to determine the call-chain
