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

152# This option breaks suspend/resume on some portables.
153#
154# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A

156# Automatic EOI is documented not to work for for the slave with the

160# MAXMEM specifies the amount of RAM on the machine; if this is not
161# specified, FreeBSD will first read the amount of memory from the CMOS
162# RAM, so the amount of memory will initially be limited to 64MB or 16MB
163# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
164# then attempt to detect the installed amount of RAM. If this probe
165# fails to detect >64MB RAM you will have to use the MAXMEM option.
166# The amount is in kilobytes, so for a machine with 128MB of RAM, it would

89# of robustness to overloads and responsivity, as well as permitting
90# accurate scheduling of the CPU time between kernel network processing
