88# DEVICE_POLLING adds support for mixed interrupt-polling handling
89# of network device drivers, which has significant benefits in terms
90# of robustness to overloads and responsivity, as well as permitting
91# accurate scheduling of the CPU time between kernel network processing
92# and other activities. The drawback is a moderate (up to 1/HZ seconds)
93# potential increase in response times.
94# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
95# to achieve smoother behaviour.
96# Additionally, you can enable/disable polling at runtime with help of
97# the ifconfig(8) utility, and select the CPU fraction reserved to
98# userland with the sysctl variable kern.polling.user_frac
99# (default 50, range 0..100).

155# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A

161# MAXMEM specifies the amount of RAM on the machine; if this is not

165# then attempt to detect the installed amount of RAM. If this probe
166# fails to detect >64MB RAM you will have to use the MAXMEM option.
167# The amount is in kilobytes, so for a machine with 128MB of RAM, it would

89# of network device drivers, which has significant benefits in terms
90# of robustness to overloads and responsivity, as well as permitting
91# accurate scheduling of the CPU time between kernel network processing

648# STREAMS device and a dynamically loadable svr4 emulator; the /usr/sbin/svr4
649# script understands that it doesn't need to load the `streams' module under
650# those circumstances.
