[RFC PATCH 0/2] insn plugin tweaks for measuring frequency

[Alex Bennée]

Hi,

This series was prompted by yesterdays email thread:

  Subject: Suggestions for TCG performance improvements

  Message-ID: <c76bde31-8f3b-2d03-b7c7-9e026d4b5873@huawei.com>

which made me think if we could leverage the TCG plugins to measure
how frequently we these flush events happen. My initial measurements
with a Debian arm64 system indicate we do some sort of tlbi
instruction every 47 thousand instructions.

Alex Bennée (2):
  tests/plugin: allow libinsn.so per-CPU counts
  tests/plugins: add instruction matching to libinsn.so
