Hi,
This patch series (and the seabios patch series following in a minute)
improve s3 support in qemu.
The patches allocates a bunch of acpi gpe bits for s3 wakeup of piix
chipset devices (ps/2 keyboard, ps/2 mouse, serial port, uhci
controller) and does the windup needed so the guest can enable+disable
wakeup per device using apci.
With this patch series applied /proc/acpi/wakeup inside the guest looks
like this ...
Device S-state Status Sysfs node
UHCI S3 *enabled pci:0000:00:01.2
KBD S3 *enabled pnp:00:02
MOU S3 *disabled pnp:00:03
COM1 S3 *disabled pnp:00:05
... and you can use "echo $device > /proc/acpi/wakeup" to toggle
enabled/disabled.
comments?
