++acpid for netlink
++
++This is Ted Felix's <http://www.tedfelix.com> branch of the acpid project
++which includes support for netlink and the input layer.
++
++/proc/acpi/event is a deprecated kernel interface for ACPI events. Newer
++kernels rely on netlink and the input layer to send ACPI-related events.
++This branch of acpid uses these new interfaces.
++
++Any comments or patches for this branch should be sent to Ted Felix:

++acpid Test Plan
++
++Note: Run all these tests with valgrind to detect memory leaks.
++
++Normal Paths
++
++* proc fs, all events
++Start acpid against /proc/acpi/event (if it exists).
++Test each of the following events:
++1. Power Button
++2. Laptop Lid Switch
++3. Sleep Button
++4. Laptop AC Adapter
++5. Laptop Battery
++
++* input layer/netlink, all events
++Start acpid against the input layer and netlink.
++Test each of the following events:
++1. Power Button
++2. Laptop Lid Switch
++3. Sleep Button
++4. Laptop AC Adapter
++5. Laptop Battery
++
++* input layer/netlink fallback
++Start acpid with a bogus events file specified via the options.
++ acpid -e /proc/acpi/bogus
++Make sure a connection is made via the input layer and netlink.
++
++* lockfile procfs
++Start acpid against the proc fs
++Try some events and make sure they are coming through.
++Create the lockfile.
++Try some events and make sure they do not come through.
++Remove the lockfile.
++Try some events and make sure they are coming through.
++
++* lockfile netlink
++Start acpid against input layer and netlink.
++Try some events and make sure they are coming through.
++Create the lockfile.
++Try some events and make sure they do not come through.
++Remove the lockfile.
++Try some events and make sure they are coming through.
++
++Debugging Paths
++
++* event logging
++Run acpid without the -l option and make sure no events are logged to syslog.
++Run acpid with the -l option and make sure events are logged to syslog.
++
++* debug mode
++Run acpid with the -d option and note that it runs in the foreground and provides debugging info to the console.
++acpid also supports up to 4 debug levels in the event handler. Might want to try "-dddd" and see what happens.
++
++* foreground mode
++Run acpid with the -f option and note that it runs in the foreground.
++Run acpid without the -f option and note that it runs in the background.
