Hello Simon,
I wanted to look at ACPI tables using the acpi command on
qemu-x86_64_defconfig.
CONFIG_CMD_ACPI=y leads to build failure without CONFIG_ACPIGEN=y.
With both enabled no ACPI table is generated. Shouldn't there at least
be a board description?
If I additionally add CONFIG_INTEL_ACPIGEN=y, I end up with bunches of
errors. Isn't the emulated CPU an Intel one?
No clue why Chrome OS stuff is coming up: Chrome OS runs on different
platforms and not all Intel systems run Chrome OS.
