ACPI tables are platform and machine type and even architecture agnostic, and as such we want to provide an internal ACPI API that only depends on platform agnostic information. For the x86 architecture, in order to build ACPI tables independently from the PC or Q35 machine types, we are moving a few MachineState structure fields into a machine type agnostic structure called AcpiConfiguration. The structure fields we move are: HotplugHandler *acpi_dev AcpiNVDIMMState acpi_nvdimm_state; FWCfgState *fw_cfg ram_addr_t below_4g_mem_size, above_4g_mem_size bool apic_xrupt_override unsigned apic_id_limit uint64_t numa_nodes uint64_t numa_mem Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> --- hw/i386/acpi-build.h | 4 +- include/hw/acpi/acpi.h | 44 ++++++++++ include/hw/i386/pc.h | 19 ++--- hw/acpi/cpu_hotplug.c | 9 +- hw/arm/virt-acpi-build.c | 10 --- hw/i386/acpi-build.c | 136 ++++++++++++++---------------- hw/i386/pc.c | 176 ++++++++++++++++++++++++--------------- hw/i386/pc_piix.c | 21 ++--- hw/i386/pc_q35.c | 21 ++--- hw/i386/xen/xen-hvm.c | 19 +++-- 10 files changed, 257 insertions(+), 202 deletions(-)
