pebs v3 support #503

Closed daishengdong closed 7 months ago

daishengdong commented 7 months ago
  1. support pebs v3
  2. I don't have a CPU with pebs_v4, and I'm not quite sure how to present the pebs record for v4 in a better way. Therefore, I haven't submitted support for v4 related features.

Thanks. Looks good. However pebs_grabber is really obsolete unless you have a really old kernel. For the newer kernels all the information in the PEBS record can be retrieved directly through perf.

Indeed, there are still some "niche" scenarios, such as wanting to perform some data collection and performance analysis in kernel mode, for which pebsgrabber would be a very good reference for kernel code. ^^
