This patch set provides an ACPI code reorganization in preparation for adding hardware-reduced support to QEMU.
The changes are coming from the NEMU [1] project where we're defining a new x86 machine type: i386/virt. This is an EFI only, ACPI hardware-reduced platform and as such we had to implement support for the latter. As a preliminary for adding hardware-reduced support to QEMU, we did some ACPI code reorganization with the following goals: * Share as much as possible of the current ACPI build APIs between legacy and hardware-reduced ACPI. * Share the ACPI build code across machine types and architectures and remove the typical PC machine type dependency. Eventually we hope to see arm/virt also re-use much of that code. The patches are also available in their own git branch [2]. [1] https://github.com/intel/nemu [2] https://github.com/intel/nemu/tree/topic/upstream/acpi v1 -> v2: * Drop the hardware-reduced implementation for now. Our next patch set will add hardware-reduced and convert arm/virt to it. * Implement the ACPI build methods as a QOM Interface Class and convert the PC machine type to it. * acpi_conf_pc_init() uses a PCMachineState pointer and not a MachineState one as its argument. v2 -> v3: * Cc all relevant maintainers, no functional changes.
