[RFC PATCH] spapr: Add SPAPR_CAP_AIL_MODES for supported AIL modes for H_SET_MODE hcall

2022-01-28 Thread Nicholas Piggin
The behaviour of the Address Translation Mode on Interrupt resource is not consistently supported by all CPU versions or all KVM versions. In particular KVM HV only supports mode 0 on POWER7 processors, and does not support mode 2 on any processors. KVM PR only supports mode 0. TCG can support
