| OPAL_HANDLE_INTERRUPT |
| ===================== |
| |
| The host OS must pass all interrupts in the `opal-interrupts` property of :ref:`device-tree/ibm,opal` in the device tree to OPAL. |
| |
| An example dt snippet is: |
| |
| .. code-block:: dts |
| |
| ibm,opal { |
| opal-interrupts = <0x10 0x11 0x12 0x13 0x14 0x20010 0x20011 0x20012 0x20013 0x20014 0xffe 0xfff 0x17fe 0x17ff 0x2ffe 0x2fff 0x37fe 0x37ff 0x20ffe 0x20fff 0x217fe 0x217ff 0x22ffe 0x22fff 0x237fe 0x237ff>; |
| }; |
| |
| When the host OS gets any of these interrupts, it must call |
| ``OPAL_HANDLE_INTERRUPT``. |
| |
| The ``OPAL_HANDLE_INTERRUPT`` call takes two parameters, one input and one output. |
| |
| ``uint32_t isn`` |
| the interrupt |
| |
| ``uint64_t *outstanding_event_mask`` |
| returns outstanding events for host OS to handle |
| |
| The host OS should then handle any outstanding events. |
| |
| See :ref:`OPAL_POLL_EVENTS` for documentation on events. |
