+ACPI on QEMU +============
+QEMU can provide ACPI tables on ARM, RISC-V, and x86.
+The following settings are needed::
- CONFIG_CMD_QFW=y
- CONFIG_ACPI=y
- CONFIG_GENERATE_ACPI_TABLE=y
+On x86 these settings are already included in the defconfig files. ARM and +RISC-V default to use device-trees.
+Instead of updating the configuration manually you can add the configuration +fragment `acpi.config` to the make command for initializing the configuration. +E.g.
+.. code-block:: bash
- make qemu-riscv64_smode_defconfig acpi.config
