hw/acpi/piix4: Restrict 'system hotplug' feature to i440fx PC machine
|
expand
|
This feature is not documented in the PIIX4 datasheet. It appears to be only used on the i440fx PC machine. Add a property to the PIIX4_PM device to restrict its use. This fixes MIPS guest crashing QEMU when accessing ioport 0xaf00.
