I guess this'd better go through ACPI tree? Thanks,

I guess this'd better go through ACPI tree? No problem with that if you prefer. Cheers, Rafael

It makes little sense but still possible to put Hyper-V guests into suspend-to-idle state. To wake them up two wakeup sources were registered in the past: hyperv-keyboard and hid-hyperv. However, since commit eed4d47efe95 ("ACPI / sleep: Ignore spurious SCI wakeups from suspend-to-idle") pm_wakeup_event() from these devices is ignored. Switch to pm_wakeup_hard_event() API as these devices are actually the only possible way to wakeup Hyper-V guests.
