Subject: [Qemu-devel] [RFC PATCH 0/9] hw/acpi: make build_madt arch agnostic
Date: Mon, 13 May 2019 14:19:04 +0800	[thread overview]
Message-ID: <20190513061913.9284-1-richardw.yang@linux.intel.com> (raw)

Now MADT is highly depend in architecture and machine type and leaves
duplicated code in different architecture. The series here tries to generalize
it.

MADT contains one main table and several sub tables. These sub tables are
highly related to architecture. Here we introduce one method to make it
architecture agnostic.

  * each architecture define its sub-table implementation function in madt_sub
  * introduces struct madt_input to collect sub table information and pass to
    build_madt

By doing so, each architecture could prepare its own sub-table implementation
and madt_input. And keep build_madt architecture agnostic.

Wei Yang (9):
  hw/acpi: expand pc_madt_cpu_entry in place
  hw/acpi: implement madt_sub[ACPI_APIC_PROCESSOR]
  hw/acpi: implement madt_sub[ACPI_APIC_LOCAL_X2APIC]
  hw/acpi: implement madt_sub[ACPI_APIC_IO]
  hw/acpi: implement madt_sub[ACPI_APIC_XRUPT_OVERRIDE]
  hw/acpi: implement madt_sub[ACPI_APIC_LOCAL_X2APIC_NMI]
  hw/acpi: implement madt_sub[ACPI_APIC_LOCAL_NMI]
  hw/acpi: factor build_madt with madt_input
  hw/acpi: implement madt_main to manipulate main madt table
