Subject: [PATCH v9 04/13] perf test: Add asm pureloop test shell script

From: Carsten Haitzler <carsten.haitzler@....com>

Add a script to drive the asm pureloop test for arm64/CoreSight that
gathers data so it passes a minimum bar for amount and quality of
content that we extract from the kernel's perf support.
