Various # instruments are enabled. The tools in # /usr/sbin/dpt_* assume these to be enabled. # DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT. # If you ant the driver to handle timeouts, enable # this option. If your system is very busy, this # option will create more trouble than solve. # DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to # wait when timing out with the above option. # DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h # DPT_LOST_IRQ When enabled, will try, once per second, to catch # any interrupt that got lost. Seems to help in some # DPT-firmware/Motherboard combinations. Minimal # cost, great benefit. # DPT_RESET_HBA Make "reset" actually reset the controller # instead of fudging it. Only enable this if you # are 100% certain you need it. device dpt # DPT options #!CAM# options DPT_MEASURE_PERFORMANCE #!CAM# options DPT_HANDLE_TIMEOUTS options DPT_TIMEOUT_FACTOR=4 options DPT_LOST_IRQ options DPT_RESET_HBA options DPT_ALLOW_MEMIO and the others are: # # Compaq Smart RAID, Mylex DAC960 and AMI MegaRAID controllers.
