freebsd-skq/sys/amd64/conf/NOTES
Marcel Moolenaar 302981e72a Remove sio(4) and related options from MI files to amd64, i386
and pc98 MD files. Remove nodevice and nooption lines specific
to sio(4) from ia64, powerpc and sparc64 NOTES. There were no
such lines for arm yet.
sio(4) is usable on less than half the platforms, not counting
a future mips platform. Its presence in MI files is therefore
increasingly becoming a burden.

# NETWORKING OPTIONS
#
# DEVICE_POLLING adds support for mixed interrupt-polling handling
# of network device drivers, which has significant benefits in terms
# of robustness to overloads and responsivity, as well as permitting
# accurate scheduling of the CPU time between kernel network processing
# and other activities. The drawback is a moderate (up to 1/HZ seconds)
# potential increase in response times.
# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
# to achieve smoother behaviour.
# Additionally, you can enable/disable polling at runtime with help of
# the ifconfig(8) utility, and select the CPU fraction reserved to
# userland with the sysctl variable kern.polling.user_frac
# (default 50, range 0..100).
#
# Not all device drivers support this mode of operation at the time of
# this writing. See polling(4) for more details.

hint.sio.0.flags="0x10"
hint.sio.0.irq="4"
# `flags' specific to sio(4).
# 0x10 enable console support for this unit. Other console flags
# (if applicable) are ignored unless this is set. Enabling
# console support does not make the unit the preferred console.
# Boot with -h or set boot_serial=YES in the loader. For sio(4)
# specifically, the 0x20 flag can also be set (see above).
# Currently, at most one unit can have console support; the
# first one (in config file order) with this flag set is
# preferred. Setting this flag for sio0 gives the old behaviour.
# 0x20 force this unit to be the console (unless there is another
# higher priority console). This replaces the COMCONSOLE option.
# 0x40 reserve this unit for low level console operations. Do not
# access the device in any normal way.
# 0x80 use this port for serial line gdb support in ddb. Also known
# as debug port.
# PnP `flags'
# 0x1 disable probing of this device. Used to prevent your modem
# from being attached as a PnP modem.
# Other flags for sio that aren't documented in the man page.
# 0x20000 enable hardware RTS/CTS and larger FIFOs. Only works for
# ST16650A-compatible UARTs.

# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
# This option breaks suspend/resume on some portables.
#
# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
# Automatic EOI is documented not to work for for the slave with the
# original i8259A, but it works for some clones and some integrated

#
# MAXMEM specifies the amount of RAM on the machine; if this is not
# specified, FreeBSD will first read the amount of memory from the CMOS
# RAM, so the amount of memory will initially be limited to 64MB or 16MB
# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
# then attempt to detect the installed amount of RAM. If this probe
# fails to detect >64MB RAM you will have to use the MAXMEM option.
# The amount is in kilobytes, so for a machine with 128MB of RAM, it would
# be 131072 (128 * 1024).
