[PATCH 0/2] perf/x86/intel/pt: Optimizations

[Alexander Shishkin <alexander.shishkin@linux.intel.com>]

Hi Peter,

The first one was earlier part of the AUX sampling patchset, but wasn't
strictly sampling related. The second one is based on an observation that
between high-order AUX allocations and the Single Range output, we don't
have to reprogram buffer-related MSRs all of the time.

  perf/x86/intel/pt: Opportunistically use single range output mode
  perf/x86/intel/pt: Prevent redundant WRMSRs
