Subject: [PATCH 17/37] perf scripts python: call-graph-from-sql.py: Provide better default column sizes
Date: Thu, 25 Oct 2018 08:10:11 -0300	[thread overview]
Message-ID: <20181025111031.3440-18-acme@kernel.org> (raw)
In-Reply-To: <20181025111031.3440-1-acme@kernel.org>

From: Adrian Hunter <adrian.hunter@intel.com>

Set initial column sizes to improve initial display.

Committer testing:

Extended instructions on testing this, using the sqlite variant:

Make sure you have the SQLite glue for python+Qt installed, on fedora 27
I used:

  # dnf install python-pyside

Collect some PT samples, say 5-secs worth, system wide:

  # perf record -r 10 -e intel_pt//u -a sleep 5
  [ perf record: Woken up 49 times to write data ]
  [ perf record: Captured and wrote 96.131 MB perf.data ]

This results in this perf.data file:

  # ls -larth perf.data
  -rw-------. 1 root root 97M Oct 23 10:11 perf.data

With the following attributes:

  # perf evlist -v
  intel_pt//u: type: 8, size: 112, config: 0x300e601, { sample_period, sample_freq }: 1, sample_type: IP|TID|TIME|CPU|IDENTIFIER, read_format: ID, disabled: 1, inherit: 1, exclude_kernel: 1, exclude_hv: 1, sample_id_all: 1
  dummy:u: type: 1, size: 112, config: 0x9, { sample_period, sample_freq }: 1, sample_type: IP|TID|TIME|CPU|IDENTIFIER, read_format: ID, inherit: 1, exclude_kernel: 1, exclude_hv: 1, mmap: 1, comm: 1, task: 1, sample_id_all: 1, mmap2: 1, comm_exec: 1, context_switch: 1
  #

Then generate the "pt_example" tables using:

  # perf script -s ~/libexec/perf-core/scripts/python/export-to-sqlite.py pt_example branches calls

  2018-10-23 11:25:25.015717 Adding indexes
  2018-10-23 11:25:28.788061 Done
  #

In my example, that perf.data file generated this db:

  # file pt_example
  pt_example: SQLite 3.x database, last written using SQLite version 3020001
  [root@seventh perf]# ls -lah pt_example
  -rw-r--r--. 1 root root 6.6G Oct 23 11:25 pt_example
  #

Then use this python script to use that db and provide a GUI:

  $ python tools/perf/scripts/python/call-graph-from-sql.py pt_example branches calls

I compared the column widths before this patch and after applying it,
the visual results match the patch intent.

The following patches will refer to this set of instructions in the "Committer
Testing" section.
