625# The 'dpt' driver provides support for old DPT controllers (http://www.dpt.com/).
626# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
627# The DPT controllers are commonly re-licensed under other brand-names -
628# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
629# Compaq are actually DPT controllers.
630#
631# See src/sys/dev/dpt for debugging and other subtle options.
632# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
633# instruments are enabled. The tools in
634# /usr/sbin/dpt_* assume these to be enabled.
635# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
636# If you ant the driver to handle timeouts, enable
637# this option. If your system is very busy, this
638# option will create more trouble than solve.
639# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
640# wait when timing out with the above option.
641# DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h
642# DPT_LOST_IRQ When enabled, will try, once per second, to catch
643# any interrupt that got lost. Seems to help in some
644# DPT-firmware/Motherboard combinations. Minimal
645# cost, great benefit.
646# DPT_RESET_HBA Make "reset" actually reset the controller
647# instead of fudging it. Only enable this if you
648# are 100% certain you need it.
