Subject: [PATCH 11/12] perf report: Add support for PERF_SAMPLE_CODE_PAGE_SIZE
Date: Tue, 17 Nov 2020 11:56:36 -0800 [thread overview]
Message-ID: <20201117195637.6499-12-kan.liang@linux.intel.com> (raw)
In-Reply-To: <20201117195637.6499-1-kan.liang@linux.intel.com>
From: Stephane Eranian <eranian@google.com>
Add a new sort dimension "code_page_size" for common sort.
With this option applied, perf can sort and report by sample's code page
size.
For example,
perf report --stdio --sort=comm,symbol,code_page_size
# To display the perf.data header info, please use
# --header/--header-only options.
#
#
# Total Lost Samples: 0
#
# Samples: 3K of event 'mem-loads:uP'
# Event count (approx.): 1470769
#
# Overhead Command Symbol Code Page Size IPC
# [IPC Coverage]
# ........ ....... ............................ ..............
# ....................

17.93% dtlb [.] Calibrate 4K -
