Nate Lawson 9b937d4836 Add devctl(4) notify support to ACPI. Various subsystems now notify
userland whenever events occur.  See the example in devd.conf below
to see how to use it.

# install if you were to add their device. This might reside in
# /usr/local/etc/devd/deqna.conf. A deqna is, in this hypothetical

# Examples of notify hooks. A notify is a generic way for a kernel
# subsystem to send event notification to userland.
#
# Here are some examples of ACPI notify handlers. ACPI subsystems that
# generate notifies include the AC adapter, power/sleep buttons,
# control method batteries, lid switch, and thermal zones.
#
# Information returned is not always the same as the ACPI notify
# events. See the ACPI specification for more information about
# notifies. Here is the information returned for each subsystem:
#
# ACAD: AC line state (0 is offline, 1 is online)
# Button: Button pressed (0 for power, 1 for sleep)
# CMBAT: ACPI battery events
# Lid: Lid state (0 is closed, 1 is open)
# Thermal: ACPI thermal zone events
#
# This example calls a script when the AC state changes, passing the
# notify value as the first argument. If the state is 0x00, it might
# call some sysctls to implement economy mode. If 0x01, it might set
# the mode to performance.
