When I booted OpenBSD from Grub2, the ACPI power-off function
didn’t work. It just quit without the shutdown sequence
when I pushed the power button of my PC.

In my investigation, the OpenBSD kernel requires the ACPI table pointer
in the boot argument. It is a member of the “bios_efiinfo_t” structure.

I wrote a patch to pass the “bios_efiinfo_t” structure which members
are filled in the same way as the OpenBSD boot loader. It works for
the OpenBSD 7.4 kernel.

I will write down what I see to fill the “bios_efiinfo_t” members.
