SYNOPSIS
pseudo-device tprof_pmi
DESCRIPTION
The
tprof_pmi driver is a
tprof(4) backend driver, which uses performance-monitoring events available for Intel Pentium 4 (NetBurst) processors.
It programs the processors so that global_power_events events (ESCR Event Select = 0x13) to raise NMIs and the NMI handler collect samples.

BUGS
The name of this driver is too generic.
