the throttling state in response to line transitions. Future plans include adding support for CPU frequency changes. Add a devd.conf entry for calling this script. The default values for this are: performance_cx_lowest="HIGH" # Use HLT (C0) online performance_throttle_state="HIGH" # 100% (no throttling) economy_cx_lowest="LOW" # Use the lowest Cx state possible economy_throttle_state="HIGH" # 100% (no throttling)

# 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.
