Hi, Yuanfang, Usually, the package from fedora offical repo is stable but not includes some new feature, so, maybe you can download the latest linux kernel source code from kernel.org, change directory to tools/perf .
Then, be a root to 'make', and try ./perf record ....... the perf tool is small, compile it needs no more than 1min, please have a try. ;-) Thanks Runzhen On Mon, Jun 17, 2013 at 02:18:52PM -0400, Yuanfang Chen wrote: > Hi all, > > Is the per-event sampling period supported now?
