NAME
profile - MINIX statistical profiling control command
SYNOPSIS
profile start [ -m memsize ] [ -o outfile ] [ -f frequency ]
profile stop
sprofalyze.pl
DESCRIPTION
This command controls MINIX system profiling. There is support for sta-
tistical profiling, which causes a CMOS interrupt to regularly sample
the position of the program counter. To enable support for this, recom-
pile the kernel with SPROFILE in <minix/config.h> set to 1.
OPTIONS
start start measuring using statistical profiling.
stop stop measuring using statistical profiling.
-m memory buffer size used to store profiling data in, allocated by
the profile command.
-o outfile
output file.
-f frequency
frequency for statistical sampling.
After you have the output file, analysis can be done using the sprofa-
lyze command.
