Hi, Corey Thanks. It is really help. :)

I note there is a line at the bottom of `perf list` says, rNNN (see 'perf list --help' on how to encode it) [Raw hardware event descriptor] I think this is what you called "raw event code", right? > Some of those raw event codes are going to be the same as the events > used internally by the kernel for the "generic hardware events", but the > only way to find out which specific hardware events are used for which > "generic hardware events", you'd have to read the kernel code.

From Documentation/perf-list.txt, I can only guess on x86 for example, I have to see "Intel® 64 and IA-32 Architectures Software Developer's Manual" to find out event name as an input to `evt2raw`. But some are success, some are failed. Is there a better way to find out what event string can be used? Thanks.
