Subject: [RFC PATCH 0/2] insn plugin tweaks for measuring frequency
Date: Fri, 3 Dec 2021 14:44:19 +0000 [thread overview]
Message-ID: <20211203144421.1445232-1-alex.bennee@linaro.org> (raw)
Hi,
This series was prompted by yesterdays email thread:
Subject: Suggestions for TCG performance improvements
Date: Thu, 2 Dec 2021 09:47:13 +0000
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.

tests/plugin: allow libinsn.so per-CPU counts
tests/plugins: add instruction matching to libinsn.so
