+Perf-Trace-Util version 0.01
+============================
+
+This module contains utility functions for use with perf script.
+
+Core.pm and Util.pm are pure Perl modules; Core.pm contains routines
+that the core perf support for Perl calls on and should always be
+'used', while Util.pm contains useful but optional utility functions
+that scripts may want to use. Context.pm contains the Perl->C
+interface that allows scripts to access data in the embedding perf
+executable; scripts wishing to do that should 'use Context.pm'.
+
+The Perl->C perf interface is completely driven by Context.xs. If you
+want to add new Perl functions that end up accessing C data in the
+perf executable, you add desciptions of the new functions here.
+scripting_context is a pointer to the perf data in the perf executable
+that you want to access - it's passed as the second parameter,
+$context, to all handler functions.
+
+After you do that:
+
+ perl Makefile.PL # to create a Makefile for the next step
+ make # to create Context.c
+
+ edit Context.c to add const to the char* file = __FILE__ line in
+ XS(boot_Perf__Trace__Context) to silence a warning/error.
+
+ You can delete the Makefile, object files and anything else that was
+ generated e.g. blib and shared library, etc, except for of course
+ Context.c
+
+ You should then be able to run the normal perf make as usual.
+
+INSTALLATION
+
+Building perf with perf script Perl scripting should install this
+module in the right place.
+
+You should make sure libperl and ExtUtils/Embed.pm are installed first
+e.g. apt-get install libperl-dev or yum install perl-ExtUtils-Embed.

+# To use this script you will need to have installed package python-pyside which
+# provides LGPL-licensed Python bindings for Qt. You will also need the package
+# libqt4-sql-psql for Qt postgresql support.
+#
+# The script assumes postgresql is running on the local machine and that the
+# user has postgresql permissions to create databases. Examples of installing
+# postgresql and adding such a user are:
+#
+# fedora:
+#
+# $ sudo yum install postgresql postgresql-server qt-postgresql
+# $ sudo su - postgres -c initdb
+# $ sudo service postgresql start
+# $ sudo su - postgres
+# $ createuser -s <your user id here> # Older versions may not support -s, in which case answer the prompt below:
+# Shall the new role be a superuser? (y/n) y
+# $ sudo yum install python-pyside
+#
+# Alternately, to use Python3 and/or pyside 2, one of the following:
+# $ sudo yum install python3-pyside
+# $ pip install --user PySide2
+# $ pip3 install --user PySide2
+#
+# ubuntu:
+#
+# $ sudo apt-get install postgresql
+# $ sudo su - postgres
+# $ createuser -s <your user id here>
+# $ sudo apt-get install python-pyside.qtsql libqt4-sql-psql
+#
+# Alternately, to use Python3 and/or pyside 2, one of the following:
+#
+# $ sudo apt-get install python3-pyside.qtsql libqt4-sql-psql
+# $ sudo apt-get install python-pyside2.qtsql libqt5sql5-psql
+# $ sudo apt-get install python3-pyside2.qtsql libqt5sql5-psql
+#
+# An example of using this script with Intel PT:
+#
+# $ perf record -e intel_pt//u ls
+# $ perf script -s ~/libexec/perf-core/scripts/python/export-to-postgresql.py pt_example branches calls

+# To browse the database, psql can be used e.g.
+#
+# $ psql pt_example
+# pt_example=# select * from samples_view where id < 100;
+# pt_example=# \d+
+# pt_example=# \d+ samples_view
+# pt_example=# \q
+#
+# An example of using the database is provided by the script
+# exported-sql-viewer.py. Refer to that script for details.
+#
+# Tables:
+#
+# The tables largely correspond to perf tools' data structures. They are largely self-explanatory.
+#
+# samples
+#
+# 'samples' is the main table. It represents what instruction was executing at a point in time
+# when something (a selected event) happened. The memory address is the instruction pointer or 'ip'.
+#
+# calls
+#
+# 'calls' represents function calls and is related to 'samples' by 'call_id' and 'return_id'.
+# 'calls' is only created when the 'calls' option to this script is specified.
+#
+# call_paths
+#
+# 'call_paths' represents all the call stacks. Each 'call' has an associated record in 'call_paths'.
+# 'calls_paths' is only created when the 'calls' option to this script is specified.
+#
+# branch_types
+#
+# 'branch_types' provides descriptions for each type of branch.
+#
+# comm_threads
+#
+# 'comm_threads' shows how 'comms' relates to 'threads'.
+#
+# comms
+#
+# 'comms' contains a record for each 'comm' - the name given to the executable that is running.
+#
+# dsos
+#
+# 'dsos' contains a record for each executable file or library.
+#
+# machines
+#
+# 'machines' can be used to distinguish virtual machines if virtualization is supported.
+#
+# selected_events
+#
+# 'selected_events' contains a record for each kind of event that has been sampled.
+#
+# symbols
+#
+# 'symbols' contains a record for each symbol. Only symbols that have samples are present.
+#
+# threads
+#
+# 'threads' contains a record for each thread.
+#
+# Views:
+#
+# Most of the tables have views for more friendly display. The views are:
+#
+# calls_view
+# call_paths_view
+# comm_threads_view
+# dsos_view
+# machines_view
+# samples_view
+# symbols_view
+# threads_view
+#
+# More examples of browsing the database with psql:
+# Note that some of the examples are not the most optimal SQL query.
+# Note that call information is only available if the script's 'calls' option has been used.
+#
+# Top 10 function calls (not aggregated by symbol):
+#
+# SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10;
+#
+# Top 10 function calls (aggregated by symbol):
+#
+# SELECT symbol_id,(SELECT name FROM symbols WHERE id = symbol_id) AS symbol,
+# SUM(elapsed_time) AS tot_elapsed_time,SUM(branch_count) AS tot_branch_count
+# FROM calls_view GROUP BY symbol_id ORDER BY tot_elapsed_time DESC LIMIT 10;
+#
+# Note that the branch count gives a rough estimation of cpu usage, so functions
+# that took a long time but have a relatively low branch count must have spent time
+# waiting.
+#
+# Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'):
+#
+# SELECT * FROM symbols_view WHERE name LIKE '%alloc%';
+#
+# Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187):
+#
+# SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10;
+#
+# Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254):
+#
+# SELECT * FROM calls_view WHERE parent_call_path_id = 254;
+#
+# Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670)
+#
+# SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%';
+#
+# Show transactions:
+#
+# SELECT * FROM samples_view WHERE event = 'transactions';
+#
+# Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false.
+# Transaction aborts have branch_type_name 'transaction abort'
+#
+# Show transaction aborts:
+#
+# SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort';
+#
+# To print a call stack requires walking the call_paths table. For example this python script:
+# #!/usr/bin/python2
+#
+# import sys
+# from PySide.QtSql import *
+#
+# if __name__ == '__main__':

+
+# 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(%)

+# Points to note:
+# 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
+# cache. To use Intel XED, libxed.so must be present. To build and install

+# git clone https://github.com/intelxed/xed
+# cd xed

+call-graph. Expanding a couple of levels of the tree and adjusting column
+widths to suit will display something like:
+<pre>

+Call Path Object Count Time(ns) Time(%) Branch Count Branch Count(%)

+<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=calltree>1.2 Call Tree</h2>
+The Call Tree report is very similar to the Context-Sensitive Call Graph, but the data is not aggregated.
+Also the 'Count' column, which would be always 1, is replaced by the 'Call Time'.
+<h2 id=allbranches>1.3 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>Instructions per Cycle (IPC)</h3>
+If available, IPC information is displayed in columns 'insn_cnt', 'cyc_cnt' and 'IPC'.
+<p><b>Intel PT note:</b> The information applies to the blocks of code ending with, and including, that branch.
+Due to the granularity of timing information, the number of cycles for some code blocks will not be known.
+In that case, 'insn_cnt', 'cyc_cnt' and 'IPC' are zero, but when 'IPC' is displayed it covers the period
+since the previous displayed 'IPC'.
+<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>1.4 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>1.4.1 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.
+<h2 id=topcallsbyelapsedtime>1.5 Top calls by elapsed time</h2>
+The Top calls by elapsed time report displays calls in descending order of time elapsed between when the function was called and when it returned.
+The data is reduced by various selection criteria. A dialog box displays available criteria which are AND'ed together.
+If not all data is fetched, a Fetch bar is provided. Ctrl-F displays a Find bar.
+<h1 id=charts>2. Charts</h1>
+<h2 id=timechartbycpu>2.1 Time chart by CPU</h2>
+This chart displays context switch information when that data is available. Refer to context_switches_view on the Tables menu.
+<h3>Features</h3>
+<ol>
+<li>Mouse over to highight the task and show the time</li>
+<li>Drag the mouse to select a region and zoom by pushing the Zoom button</li>
+<li>Go back and forward by pressing the arrow buttons</li>
+<li>If call information is available, right-click to show a call tree opened to that task and time.
+Note, the call tree may take some time to appear, and there may not be call information for the task or time selected.
+</li>
+</ol>
+<h3>Important</h3>
+The graph can be misleading in the following respects:
+<ol>
+<li>The graph shows the first task on each CPU as running from the beginning of the time range.
+Because tracing might start on different CPUs at different times, that is not necessarily the case.
+Refer to context_switches_view on the Tables menu to understand what data the graph is based upon.</li>
+<li>Similarly, the last task on each CPU can be showing running longer than it really was.
+Again, refer to context_switches_view on the Tables menu to understand what data the graph is based upon.</li>
+<li>When the mouse is over a task, the highlighted task might not be visible on the legend without scrolling if the legend does not fit fully in the window</li>
+</ol>
+<h1 id=tables>3. 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.
