  [Bug] Perf cannot use Intel PT and LBRs simultaneously at GLM and GLK

Status in intel:
  Fix Released

Status in linux source package in Bionic:

Bug description:

  An earlier kernel patch allowed enabling PT and LBR at the same time on 
  commit ccbebba4c6bf ("perf/x86/intel/pt: Bypass PT vs. LBR exclusivity if the 
core supports it")
  However, users still cannot use Intel PT and LBRs simultaneously.
  $ sudo perf record -e cycles,intel_pt//u -b – sleep 1
  PMU Hardware doesn't support sampling/overflow-interrupts.
