Subject: [PATCH v2 0/5] perf report: Support sorting all blocks by cycles
Date: Tue, 15 Oct 2019 13:33:45 +0800 [thread overview]
Message-ID: <20191015053350.13909-1-yao.jin@linux.intel.com> (raw)
It would be useful to support sorting for all blocks by the
sampled cycles percent per block. This is useful to concentrate
on the globally hottest blocks.
This patch series implements a new sort option "total_cycles" which
sorts all blocks by 'Sampled Cycles%'. The 'Sampled Cycles%' is
block sampled cycles aggregation / total sampled cycles
For example,
perf record -b ./div
perf report -s total_cycles --stdio
# To display the perf.data header info, please use --header/--header-only options.
#
#
# Total Lost Samples: 0
#
# Samples: 2M of event 'cycles'
# Event count (approx.): 2753248
#
# Sampled Cycles% Sampled Cycles Avg Cycles% Avg Cycles [Program Block Range] Shared Object
# ............... .............. ........... .......... ................................................................. ....................

......
This patch series supports both stdio and tui. And also with the supporting
of --percent-limit.
