QEMU 8.1.2 can create ACPI tables for the ARM and RISC-V architectures Allow passing them through to the operating system. Provide a new config fragment that enables this.
v2: consider ARM architecture too invoke write_acpi_tables() via EVT_LAST_STAGE_INIT
Heinrich Schuchardt (9): acpi: Kconfig symbol CONFIG_QFW_ACPI acpi: carve out qfw_acpi.c arrm: add ACPI fields to global data risc-v: add ACPI fields to global data acpi: enable writing ACPI tables on QEMU risc-v: add support for QEMU firmware tables riscv: allow usage of ACPI configs: qemu: add config fragment for ACPI arm: enable support for QEMU firmware tables
