Subject: [PATCH 0/3] perf intel-pt: Add support for emulated ptwrite

Hi

Here are 3 patches (on top of "perf intel-pt: Add link to the perf wiki's
Intel PT page") to add support for decoding emulated ptwrite i.e. for
hardware that does not have the ptwrite instruction.


Adrian Hunter (3):
      perf intel-pt: Add support for emulated ptwrite
      perf script: Print Intel ptwrite value as a string if it is ASCII
      perf scripts python: intel-pt-events.py: Print ptwrite value as a string if it is ASCII
