TPROF(4)                   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.

SEE ALSO
     tprof_amdpmi(4), tprof_pmi(4), tprof(8)

AUTHORS
     The tprof driver was written by YAMAMOTO Takashi.

BUGS
     There is no way to configure multiple backend drivers statically.
