Win10 shutdown does not soft-off #64

Closed andreiw closed 5 years ago

andreiw commented 5 years ago

The screen goes blank, but not black, and the green led doesn't blink, meaning that Windows never called PSCI to power-off.

poweroff -f does the right thing in Linux.... possible some ACPI-related shenanigans

Speaking of blinking LEDs, when I install the ported RPIQ driver, the green LED keeps blinking all the time. But the driver does work though (I can send ioctls to it for mailbox stuff).

andreiw commented 5 years ago

Well, it's either the driver or the GPU...

I really wish ACPI added an OpRegion for SMCs. Grrr.

I think I could get away with a \_PTS method to basically implement https://github.com/andreiw/raspberry-pi3-atf/blob/11c9a950ea89a753e473c8b66d6cfe23e9ce7e42/plat/rpi3/rpi3_pm.c#L220

Why or why couldn't Arm FFH be a general-purpose mechanism? Mystery.

Anyway, what compounds testing this is the USB driver quality getting in the way. Even rebooting frequently hangs due to the USB driver hangs.

Now it turns off properly. The issue was the faulty Windows USB driver.

Ok, good to know
