| |
| Modelled on the PAPR call. |
| |
| For P9 and above systems where host doesn't know about interrupt controller. |
| An OS can instead make OPAL calls for XICS emulation. |
| |
| For an OS to use this OPAL call, an ``ibm,opal-intc`` compatible device must |
| exist in the device tree (see :ref:`xive-device-tree`). If OPAL does not create |
| such a device, the host OS MUST NOT use this call. |
