The main Intel PT change is in patch 5 and there is a small example in the There are a couple of very minor and essentially unrelated changes in The 2nd patch adds the new option flag to auxtrace.

If necessary, the size of output on error is configurable via perf config,Īnd perf_config_scan() was added in the 1st patch to make that simpler. Getting interesting bits is useful for analyzing errors.
