# exported-sql-viewer.py: view data from sql database
|
|
# 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(%)

# 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
|
|
# libxed.so:

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