Subject: perf trace report with time consumed

Hey all,

with "perf trace record --call-graph dwarf" I get a nice data file with 
potentially everything required to find slow syscalls in user space 
applications. But I'm missing a way to rewrite the data file to let "perf 
report" attribute samples with the time spent as cost, instead of the raw 
number of syscalls, i.e. samples.

Is this functionality there already? Or do I have to write another "perf 
inject" command, similar to "perf inject --sched-stat"?

Thanks
