#define OPAL_INT_SET_CPPR 123 static int64_t opal_int_set_cppr(uint8_t cppr);
Modelled on the
H_CPPR 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 I - Device-tree updates). If OPAL does not create
such a device, the host OS MUST NOT use this call.
