1.1 Context-Sensitive Call Graph

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:

Points to note:

Find

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.

1.2 Call Tree

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'.

1.3 All branches

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.

Disassembly

Open a branch to display disassembly. This only works if:
  1. The disassembler is available. Currently, only Intel XED is supported - see Intel XED Setup
  2. 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.

Intel XED Setup

To use Intel XED, libxed.so must be present. To build and install libxed.so: 
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

Instructions per Cycle (IPC)

If available, IPC information is displayed in columns 'insn_cnt', 'cyc_cnt' and 'IPC'.

Intel PT note: 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'.

Find

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.

1.4 Selected branches

This is the same as the All branches report but with the data reduced by various selection criteria. A dialog box displays available criteria which are AND'ed together.

1.4.1 Time ranges

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: 
	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
N.B. Due to the granularity of timestamps, there could be no branches in any given time range.

1.5 Top calls by elapsed time

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.

2. Charts

2.1 Time chart by CPU

This chart displays context switch information when that data is available. Refer to context_switches_view on the Tables menu.

Features

  1. Mouse over to highight the task and show the time
  2. Drag the mouse to select a region and zoom by pushing the Zoom button
  3. Go back and forward by pressing the arrow buttons
  4. 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.

Important

The graph can be misleading in the following respects:
  1. 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.
  2. 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.
  3. 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

3. Tables

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.

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.

Find

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.

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.
