Hi folks,
Pardon if I slightly hijack this thread, but we'd like to do something
similar to this on powerpc.
I've been telling people not to use PERF_SAMPLE_RAW because it provides
no way for the consumer to know what data they're getting, and it's not
extensible in any way.
So is shovelling things out using PERF_SAMPLE_RAW generally acceptable
for "advanced usage" scenarios?
cheers
