6 hatari_profile - Post-processor for Hatari profiler data
7
9 hatari_profile.py [options] <datafiles>
10
12 A Python script to post-process data produced by Hatari profiler "save"
13 commands, both for CPU and DSP:
14 profile save <filename>
15 dspprofile save <filename>
16 It can provide function level (CPU and DSP) processor usage information
18 for anything Hatari profiler records: instruction counts, processor
19 cycles and depending on processor, also instruction cache misses or
20 cycle differences.
21 This information can be provided as ASCII list of heaviest functions,
23 as callgraphs (if profile data includes caller information), or as
24 callgrind format export which can be viewed in (Linux) Kcachegrind GUI.
25
27 Invoking hatari_profile without arguments lists all of its options.
28
30 Regardless of whether profile data contains some symbol information,
31 you should always give script all relevant debug symbols, otherwise
32 costs might not get correctly assigned to symbols preceding those
33 costs.
34 This post-processes profile data for EmuTOS (ROM), with symbol file
36 having fixed/absolute addresses (-a), shows statistics (-s) and top
37 lists (-t), but limits list output to anything taking over 2% (-l 2)
38 and includes "propagated" subroutine call costs (-p):

90 This creates GraphViz callgraph files (-g) and Kcachegrind callgrind
92 data file (-k) from Bad Mood (Doom BSP viewer) profile. Symbols for
93 the program are TEXT section relative (-r), calls to some interrupt
94 routines in the program are ignored as they aren't real calls, call‐
95 graph nodes using over 2% are highlighted, and there are some options
96 to limit and simplify the graph:
