ACPI on QEMU
|
|
============
|
|
|
|
QEMU can provide ACPI tables on ARM, RISC-V (since QEMU v8.0.0), and x86.
|
|
|
|
The following U-Boot settings are needed for ACPI support::
|
|
|
|
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
|
