SubjectRe: [PATCH 00/12] perf/x86-ibs: Precise event sampling with IBS for AMD CPUs

Cool - this makes IBS really useful!

Mind posting some perf annotate output of any well-known kernel
function showing skiddy '-e cpu-cycles' output versus skid-less
'-e cpu-cycles:p' output?

I'm curious how well this works in practice.

Thanks,

Ingo
