#define OPAL_INT_SET_MFRR 125

static int64_t opal_int_set_mfrr(uint32_t cpu, uint8_t mfrr);
|
|
|
|
|
|
Modelled on the ``H_IPI`` 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.
