HATARI_PROFILE(1)	       Hatari utilities		     HATARI_PROFILE(1)

NAME
       hatari_profile -	Post-processor for Hatari profiler data

SYNOPSIS
       hatari_profile.py [options] <datafiles>

DESCRIPTION
       A Python	script to post-process data produced by	Hatari profiler	"save"
       commands, both for CPU and DSP:
	    profile save <filename>
	    dspprofile save <filename>

       It can provide function level (CPU and DSP) processor usage information
       for anything Hatari profiler records: instruction counts, processor cy-
       cles and	depending on processor,	also instruction cache misses or cycle
       differences.

       This  information  can be provided as ASCII list	of heaviest functions,
       as callgraphs (if profile data  includes	 caller	 information),	or  as
       callgrind format	export which can be viewed in (Linux) Kcachegrind GUI.

OPTIONS
       Invoking	hatari_profile without arguments lists all of its options.

USAGE EXAMPLES
       Regardless  of  whether	profile	data contains some symbol information,
       you should always give script all  relevant  debug  symbols,  otherwise
       costs  might  not  get  correctly  assigned  to symbols preceding those
       costs.

       This post-processes profile data	for EmuTOS  (ROM),  with  symbol  file
       having  fixed/absolute  addresses  (-a),	 shows statistics (-s) and top
       lists (-t), but limits list output to anything taking over  2%  (-l  2)
       and includes "propagated" subroutine call costs (-p):

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