tprof — a sampling
based profiler
pseudo-device tprof
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.
The tprof driver was written by
YAMAMOTO Takashi.
There is no way to configure multiple backend drivers statically.
