Subject: [PATCH V2 11/12] perf report: Add support for PERF_SAMPLE_CODE_PAGE_SIZE
Date: Mon, 30 Nov 2020 09:28:02 -0800	[thread overview]
Message-ID: <20201130172803.2676-12-kan.liang@linux.intel.com> (raw)
In-Reply-To: <20201130172803.2676-1-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]
 # ........  .......  ............................  ..............
