"""
|
|
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.)
