TPROF(4)                NetBSD Kernel Interfaces Manual               TPROF(4)


NAME

     tprof -- a sampling based profiler


SYNOPSIS

     pseudo-device tprof


DESCRIPTION

     The tprof driver provides kernel services necessary for tprof(8).

     Specifically, it makes its backend driver collect profiling samples and
     provide them to the userland consumer.

     The API/ABI is currently undocumented and will likely change in future
     without keeping compatibility.

     On x86, the tprof_x86 module must be loaded in addition to the tprof
     driver.


SEE ALSO

     tprof(8)


AUTHORS

     The tprof driver was written by YAMAMOTO Takashi.


BUGS

     There is no way to configure multiple backend drivers statically.
