We're adding stuff to piix4 which was never there. At a minimum this needs to be documented. Also needs to be -M pc-1.1 and later only.
Where should this be documented? PCI/ACPI hotplug addresses are documented in docs/specs/acpi_pci_hotplug.txt but for CPU hotplug documentation (i.e. for the existing PROC_BASE) I don't see relevant documentation. I will create a docs/specs/acpi_cpu_hotplug.txt if that sounds reasonable.
For pc-1.1, a new QEMUmachine type will be needed I assume. Should a check be made against the machine version in the piix4 code? any relevant examples?
thanks,
