Create ACPI tables and return the RSDP. The basic tables DSDT/FACP/MADT/XSDT are constructed in this function.

Arguments

• guest_mem - The guest memory where the tables will be stored.
• num_cpus - Used to construct the MADT.
• sci_irq - Used to fill the FACP SCI_INTERRUPT field, which is going to be used by the ACPI drivers to register sci handler.
• acpi_dev_resource - resouces needed by the ACPI devices for creating tables.
• host_cpus - The CPU affinity per CPU used to get corresponding CPUs’ apic id and set these apic id in MADT if --host-cpu-topology option is set.
• apic_ids - The apic id for vCPU will be sent to KVM by KVM_CREATE_VCPU ioctl.
• pci_rqs - PCI device to IRQ number assignments as returned by arch::generate_pci_root() (device address, IRQ number, and PCI interrupt pin assignment).
• pcie_cfg_mmio - Base address for the pcie enhanced configuration access mechanism
• max_bus - Max bus number in MCFG table
