Create a QMP command to be used for generic ACPI APEI hardware error
injection (HEST) via GHESv2, and add support for it for ARM guests.
Error injection uses ACPI_HEST_SRC_ID_QMP source ID to be platform
independent. This is mapped at arch virt bindings, depending on the
types supported by QEMU and by the BIOS. So, on ARM, this is supported
via ACPI_GHES_NOTIFY_GPIO notification type.
This patch was co-authored:
- original ghes logic to inject a simple ARM record by Shiju Jose;
- generic logic to handle block addresses by Jonathan Cameron;
- generic GHESv2 error inject by Mauro Carvalho Chehab;
