Subject: [PATCH v4 0/4] perf: Support a new 'percore' event qualifier
Date: Fri, 12 Apr 2019 21:59:46 +0800 [thread overview]
Message-ID: <1555077590-27664-1-git-send-email-yao.jin@linux.intel.com> (raw)
The 'percore' event qualifier which sums up the event counts for both
hardware threads in a core. For example,
perf stat -e cpu/event=0,umask=0x3,percore=1/,cpu/event=0,umask=0x3/
In this example, we count the event 'ref-cycles' per-core and per-CPU in
one perf stat command-line.
We can already support per-core counting with --per-core, but it's
often useful to do this together with other metrics that are collected
per CPU (per hardware thread). So this patch series supports this
per-core counting on a event level.
v4:
---
Add percore qualifier to documantation.
Rebase to latest perf/core branch
v3:
---
Simplify the patch: "perf: Add a 'percore' event qualifier"
Other patches don't have changes.
v2:
---
1. Change 'coresum' to 'percore'.
2. Move the aggregate counts printing to a seperate patch.
Jin Yao (4):
perf: Add a 'percore' event qualifier
perf stat: Factor out aggregate counts printing
perf stat: Support 'percore' event qualifier
perf test: Add a simple test for term 'percore'
