Subject: [PATCH v2 0/4] perf: Support a new 'percore' event qualifier
Date: Sun, 17 Mar 2019 00:34:24 +0800	[thread overview]
Message-ID: <1552754068-10325-1-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.

 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'
