NAME

kprof - display kernel profiling data

SYNOPSIS

kprof kernel kpdata

DESCRIPTION

Kprof presents the data accumulated by the kernel profiling device, kprof(3). The symbol table is taken from the file kernel, the executable file of the operating system kernel that was profiled. The data file kpdata is usually a copy of /dev/kpdata from the device running the profiling kernel.

The symbol table is read and correlated with the profile data. For each symbol, the time (in milliseconds) spent executing between that symbol and the next is printed (in decreasing order), together with the percentage of the total time.
