This series factors out AcpiCpuAmlIfClass::madt_cpu from AcpiDeviceIfClass. By letting the (x86) CPUs implement the new interface, AML generation is delegated to the CPUs, freeing the ACPI controllers from worrying about x86 CPU specifics. The delegation to the CPUs is especially interesting for the PIIX4 PM since it is also used in MIPS only contexts where no ACPI bios is available.
Furthermore, the series introduces qbus_build_aml() which replaces isa_build_aml() and resolves some open coding. v4: - Squash qbus_build_aml() patches into one (Igor) - Don't use a bare function pointer for AcpiDeviceIfClass::madt_cpu (Igor) Testing done: * `make check` * `qemu-system-x86_64 -M pc -m 2G -cdrom manjaro-kde-21.2.6-220416-linux515.iso` * `qemu-system-x86_64 -M q35 -m 2G -cdrom \ manjaro-kde-21.2.6-220416-linux515.iso` v3: - Clean up includes in AcpiDeviceIfClass::madt_cpu sub series last (Markus) - Restructure qbus_build_aml() sub series (Phil, me) v2: - Don't inline qbus_build_aml() (Phil) - Add 'hw/acpi/piix4: No need to #include "hw/southbridge/piix.h"' Bernhard Beschow (7): hw/i386/acpi-build: Remove unused attributes hw/isa/isa-bus: Turn isa_build_aml() into qbus_build_aml() hw/acpi/piix4: No need to #include "hw/southbridge/piix.h" hw/acpi/acpi_dev_interface: Remove unused parameter from AcpiDeviceIfClass::madt_cpu hw/acpi/acpi_dev_interface: Factor out TYPE_ACPI_CPU_AML_IF hw/acpi/acpi_dev_interface: Remove now unused #include "hw/boards.h" hw/i386/pc: Unexport pc_madt_cpu_entry() hw/acpi/hmat.h | 3 +- hw/i386/acpi-common.h | 3 +- include/hw/acpi/acpi_aml_interface.h | 3 ++ include/hw/acpi/acpi_cpu_interface.h | 26 ++++++++++++++++ include/hw/acpi/acpi_dev_interface.h | 4 --- include/hw/i386/pc.h | 6 ---- include/hw/isa/isa.h | 1 - hw/acpi/acpi-x86-stub.c | 7 ----- hw/acpi/acpi_interface.c | 18 ++++++++++- hw/acpi/cpu.c | 13 ++++---- hw/acpi/hmat.c | 1 + hw/acpi/memory_hotplug.c | 1 + hw/acpi/piix4.c | 3 -- hw/i2c/smbus_ich9.c | 5 +-- hw/i386/acpi-build.c | 5 +-- hw/i386/acpi-common.c | 42 +++---------------------- hw/i386/acpi-microvm.c | 6 ++-- hw/i386/generic_event_device_x86.c | 9 ------ hw/isa/isa-bus.c | 10 ------ hw/isa/lpc_ich9.c | 6 +--- hw/isa/piix3.c | 5 +-- monitor/qmp-cmds.c | 1 + target/i386/cpu.c | 46 ++++++++++++++++++++++++++++ 23 files changed, 117 insertions(+), 107 deletions(-) create mode 100644 include/hw/acpi/acpi_cpu_interface.h -- 2.39.1
