"""
A tool for post-processing emulator HW profiling data.
In Hatari debugger you get (CPU) profiling data with the following
commands (for Falcon DSP data, prefix commands with 'dsp'):
profile on
continue
...
profile save <file name>
Profiling information for code addresses is summed together and
assigned to (function) symbols to which those addresses belong to.
All addresses between two symbol names (in profile file) or symbol
addresses (read from symbols files) are assumed to belong to the
preceeding function/symbol.
Tool output will contain at least:
- (deduced) call counts,
- executed instruction counts, and
- spent processor cycles.
If profile data contains other information (e.g. cache misses),
that is also shown.
Provided symbol information should be in same format as for Hatari
debugger 'symbols' command. Note that files containing absolute
addresses and ones containing relatives addresses need to be given
with different options!
Usage: hatari-profile [options] <profile files>
Options:
-a <symbols> absolute symbol address information file
-r <symbols> TEXT (code section) relative symbols file
-s output profile statistics
-t list top functions for all profile items
-i add address and time information to lists
-f <count> list at least first <count> items
-l <limit> list at least items which percentage >= limit
-p show costs propagated up in the call hierarchy
-o <file name> statistics output file name (default is stdout)
-g write <profile>.dot callgraph files
-k write <profile>.cg Callgrind format output
(for Kcachegrind GUI)
-v verbose output
Long options for above are:
--absolute
--relative
--stats
--top
--info
--first
--limit
--propagate
--output
--graph
--callgrind
--verbose
(Timing --info is shown only for cycles list.)
For example:
hatari-profile -a etos512k.sym -st -g -f 10 prof1.txt prof2.txt
For each given profile file, output is:
- profile statistics
- a sorted list of functions, for each of the profile data items
(calls, instructions, cycles...)
- callgraph in DOT format for each of the profile data items, for
each of the profile files, saved to <filename>-<itemindex>.dot file
(prof1-0.dot, prof1-2.dot etc)
When both -l and -f options are specified, they're combined. Produced
lists contain at least the number of items specified for -f option,
and more if there are additional items which percentage of the total
value is larger than one given for -l option. In callgraphs these
options mainly affect which nodes are highlighted.
If profile includes "caller" information, -p option can be used to see:
- costs also for everything else that a subroutine calls,
- subroutine's "own" cost, which exclude costs for any further
subroutine calls that it does.
(For more information on how these differ from normally shown costs,
see Profiling section in Hatari manual.)
Nodes with subroutine costs are shown as diamonds in the callgraphs.
Call information filtering options:
--no-calls <[bersux]+> remove calls of given types, default = 'rux'
--ignore-to <list> ignore calls to these symbols
--compact leave only single connection for symbols
that are directly connected
(Give --no-calls option an unknown type to see type descriptions.)
<list> is a comma separate list of symbol names, like this:
--ignore-to _int_timerc,_int_vbl
These options change which calls are reported for functions and can
affect the shape & complexity of the graph a lot. If you e.g. want
to see just nodes with costs specific to -p option, use "--no-calls
berux" option.
If default --no-calls type removal doesn't remove all interrupt
handling switches [1], give handler names to --ignore-to option.
In callgraphs, one can then investigate them separately using
"no-calls '' --only <name>" options.
[1] Switching to interrupt handler gets recorded as "a call" to it
by the profiler, and such "calls" can happen at any time.
NOTE: costs shown with -p option include costs of exception handling
code that interrupts the function calls. Normally effect of this
should be minimal, but by providing symbol addresses for interrupt
handlers their costs will be visible in output.
Callgraph filtering options to remove nodes and edges from the graph:
--no-intermediate remove nodes with single parent & child
--no-leafs remove nodes which have either:
- one parent and no children,
- one child and no parents, or
- no children nor parents
--no-limited remove _all_ nodes below -l limit
--only-subroutines remove non-subroutine nodes below -l limit
--ignore <list> no nodes for these symbols
--ignore-from <list> no arrows from these symbols
--only <list> only these symbols and their callers
Leaf and intermediate node removal options remove only nodes which
own costs fall below limit given with the -l option. Remember to
give -l option with them as -l defaults to 0.0 on callgraphs!
Functions which are called from everywhere (like malloc), may be good
candinates for '--ignore' option when one wants a more readable graph.
One can then investigate them separately with the '--only <function>'
option.
NOTE: Only directly connected symbols are compacted. You can still
see multiple arrows between nodes in callgraphs with --compact option
if intermediate nodes have been removed with above options.
Callgraph visualization options:
--mark <list> mark nodes which names contain any
of the listed string(s)
-e, --emph-limit <limit> percentage limit for highlighted nodes
When -e limit is given, it is used for deciding which nodes to
highlight, not -f & -l options. Normally it should be larger than -l
option value.
Nodes with costs that exceed the highlight limit have red outline.
If node's own cost exceeds the limit, it has also gray background.
To convert dot files e.g. to SVG, use:
dot -Tsvg graph.dot > graph.svg
('dot' tool is in Graphviz package.)
