Input: i8042 - enable keyboard wakeups by default when s2idle is
used
Previously, on typical consumer laptops, pressing a key on the keyboard
when the system is in suspend would cause it to wake up (default or
unconditional behaviour). This happens because the EC generates a SCI
interrupt in this scenario.
That is no longer true on modern laptops based on Intel WhiskeyLake,
including Acer Swift SF314-55G, Asus UX333FA, Asus UX433FN and Asus
UX533FD. We confirmed with Asus EC engineers that the "Modern Standby"
design has been modified so that the EC no longer generates a SCI
in this case; the keyboard controller itself should be used for wakeup.
In order to retain the standard behaviour of being able to use the
keyboard to wake up the system, enable serio wakeups by default on
platforms that are using s2idle.
This change makes the keyboard wakeup behavior in aligned with other
major OS (i.e. Windows and macOS).
This can be changed to the "old" behavior by the following:
# echo disabled > /sys/bus/serio/devices/serio0/power/wakeup
