[PATCH v2] hw/arm: Restrict APEI tables generation to the 'virt' machine
Posted by Philippe Mathieu-Daudé 3 years, 7 months ago 
While APEI is a generic ACPI feature (usable by X86 and ARM64), only
the 'virt' machine uses it, by enabling the RAS Virtualization. See
commit 2afa8c8519: "hw/arm/virt: Introduce a RAS machine option").

Restrict the APEI tables generation code to the single user: the virt
machine. If another machine wants to use it, it simply has to 'select
ACPI_APEI' in its Kconfig.

Fixes: aa16508f1d ("ACPI: Build related register address fields via hardware error fw_cfg blob")

I assume this needs a respin now Paolo's reworking of
default-configs/ has gone into master.

Ah indeed. The diff is simply:

-default-configs/arm-softmmu.mak
+default-configs/devices/arm-softmmu.mak

I'll send a v3, thanks for updating me.
