[Qemu-ppc] [PATCH v5 12/14] xics: Implement H_XIRR_X |
Date: |

From: Benjamin Herrenschmidt <address@hidden>
This implements H_XIRR_X hypercall in addition to H_XIRR as
it is mandatory for PAPR+ and there is no way for the guest to
detect whether it is supported or not so just add it.
As the Partition Adjunct Option is not supported at the moment,
the CPPR parameter of the hypercall is ignored.
