From bfd8f72c2778f5bd63dc9eb6d23bd7a0d99cff6d Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Fri, 17 Nov 2017 13:42:58 -0800 Subject: [PATCH] perf record: Synthesize unit/scale/... in event update Move the code to synthesize event updates for scale/unit/cpus to a common utility file, and use it both from stat and record. This allows to access scale and other extra qualifiers from perf script.
