TPROF(4)                     Device Drivers 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.
