The scripts in scripts/python are intended to be run from 'perf script' and the Python version used is dictated by how perf was built (PYTHON=). Also most distros follow pep-0394 which recommends that /usr/bin/python refer to Python2 and so may not exist on the system (if PYTHON=python3). - Remove the explicit shebang - Install the scripts as mode 644 Signed-off-by: Tony Jones <tonyj@suse.de> Acked-by: Jiri Olsa <jolsa@kernel.org> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jonathan Corbet <corbet@lwn.net> Cc: Ravi Bangoria <ravi.bangoria@linux.ibm.com> Cc: Seeteena Thoufeek <s1seetee@linux.vnet.ibm.com> Link: http://lkml.kernel.org/r/20190124005229.16146-6-tonyj@suse.de Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

# Copyright (c) 2014-2018, Intel Corporation.
|
|
|
|
# To use this script you will need to have exported data using either the
|
|
# export-to-sqlite.py or the export-to-postgresql.py script. Refer to those
|
|
# scripts for details.
|
|
#
|
|
# Following on from the example in the export scripts, a
|
|
# call-graph can be displayed for the pt_example database like this:
|
|
#
|
|
# python tools/perf/scripts/python/exported-sql-viewer.py pt_example
|
|
#
|
|
# Note that for PostgreSQL, this script supports connecting to remote databases
|
|
# by setting hostname, port, username, password, and dbname e.g.
|
|
#
|
|
# python tools/perf/scripts/python/exported-sql-viewer.py "hostname=myhost username=myuser password=mypassword dbname=pt_example"
|
|
#
|
|
# The result is a GUI window with a tree representing a context-sensitive
|
|
# call-graph. Expanding a couple of levels of the tree and adjusting column
|
|
# widths to suit will display something like:
|
|
#
|
|
# Call Graph: pt_example
|
|
# Call Path Object Count Time(ns) Time(%) Branch Count Branch Count(%)

|
|
# The top level is a command name (comm)
|
|
# The next level is a thread (pid:tid)
|
|
# Subsequent levels are functions
|
|
# 'Count' is the number of calls
|
|
# 'Time' is the elapsed time until the function returns
|
|
# Percentages are relative to the level above
|

# 'Branch Count' is the total number of branches for that function and all

# functions that it calls

|
|
# There is also a "All branches" report, which displays branches and
|
|
# possibly disassembly. However, presently, the only supported disassembler is
|
|
# Intel XED, and additionally the object code must be present in perf build ID

<h3>Points to note:</h3>
|
|
<ul>
|
|
<li>The top level is a command name (comm)</li>
|
|
<li>The next level is a thread (pid:tid)</li>
|
|
<li>Subsequent levels are functions</li>
|
|
<li>'Count' is the number of calls</li>
|
|
<li>'Time' is the elapsed time until the function returns</li>
|
|
<li>Percentages are relative to the level above</li>
|
|
<li>'Branch Count' is the total number of branches for that function and all functions that it calls
|
|
</ul>
|
|
<h3>Find</h3>
|
|
Ctrl-F displays a Find bar which finds function names by either an exact match or a pattern match.
|
|
The pattern matching symbols are ? for any character and * for zero or more characters.
|
|
<h2 id=allbranches>1.2 All branches</h2>
|
|
The All branches report displays all branches in chronological order.
|
|
Not all data is fetched immediately. More records can be fetched using the Fetch bar provided.
|
|
<h3>Disassembly</h3>
|
|
Open a branch to display disassembly. This only works if:
|
|
<ol>
|
|
<li>The disassembler is available. Currently, only Intel XED is supported - see <a href=#xed>Intel XED Setup</a></li>
|
|
<li>The object code is available. Currently, only the perf build ID cache is searched for object code.
|
|
The default directory ~/.debug can be overridden by setting environment variable PERF_BUILDID_DIR.
|
|
One exception is kcore where the DSO long name is used (refer dsos_view on the Tables menu),
|
|
or alternatively, set environment variable PERF_KCORE to the kcore file name.</li>
|
|
</ol>
|
|
<h4 id=xed>Intel XED Setup</h4>
|
|
To use Intel XED, libxed.so must be present. To build and install libxed.so:
|
|
<pre>
|
|
git clone https://github.com/intelxed/mbuild.git mbuild
|
|
git clone https://github.com/intelxed/xed
|
|
cd xed
|
|
./mfile.py --share
|
|
sudo ./mfile.py --prefix=/usr/local install
|
|
sudo ldconfig
|
|
</pre>
|
|
<h3>Find</h3>
|
|
Ctrl-F displays a Find bar which finds substrings by either an exact match or a regular expression match.
|
|
Refer to Python documentation for the regular expression syntax.
|
|
All columns are searched, but only currently fetched rows are searched.
|
|
<h2 id=selectedbranches>1.3 Selected branches</h2>
|
|
This is the same as the <a href=#allbranches>All branches</a> report but with the data reduced
|
|
by various selection criteria. A dialog box displays available criteria which are AND'ed together.
|
|
<h3>1.3.1 Time ranges</h3>
|
|
The time ranges hint text shows the total time range. Relative time ranges can also be entered in
|
|
ms, us or ns. Also, negative values are relative to the end of trace. Examples:
|
|
<pre>
|
|
81073085947329-81073085958238 From 81073085947329 to 81073085958238
|
|
100us-200us From 100us to 200us
|
|
10ms- From 10ms to the end
|
|
-100ns The first 100ns
|
|
-10ms- The last 10ms
|
|
</pre>
|
|
N.B. Due to the granularity of timestamps, there could be no branches in any given time range.
|
|
<h1 id=tables>2. Tables</h1>
|
|
The Tables menu shows all tables and views in the database. Most tables have an associated view
|
|
which displays the information in a more friendly way. Not all data for large tables is fetched
|
|
immediately. More records can be fetched using the Fetch bar provided. Columns can be sorted,
|
|
but that can be slow for large tables.
|
|
<p>There are also tables of database meta-information.
|
|
For SQLite3 databases, the sqlite_master table is included.
|
|
For PostgreSQL databases, information_schema.tables/views/columns are included.
|
|
<h3>Find</h3>
|
|
Ctrl-F displays a Find bar which finds substrings by either an exact match or a regular expression match.
|
|
Refer to Python documentation for the regular expression syntax.
|
|
All columns are searched, but only currently fetched rows are searched.
|
|
<p>N.B. Results are found in id order, so if the table is re-ordered, find-next and find-previous
|
|
will go to the next/previous result in id order, instead of display order.
