I am trying to remove the rfi instruction from the set of the CPU and I think we need to introduce a new PPC_* bit for GEN_HANDLER to : +GEN_HANDLER(rfi, 0x13, 0x12, 0x01, 0x03FF8001, PPC_RFI), we can also keep the test on PPC_SEGMENT_64B in the handler which works perfectly fine. > rfi exists on all 32-bit processors and all non-Book3S (aka server aka > segment/hash) 64-bit. So PPC_SEGMENT_64B is the test we want. > > IE. rfi does exist on e5500 ok. Cheers, C.
