What firmware out of curiosity ? The treeboot thingy ? And yes, we definitely need an enabling HV call, ie, we stick to traps until it's enabled, we are talking about virtual space here so the kernel takes over and put what it wants up there for BookE. For server, we really don't care much what's in the ROM after we have booted neither. But yes, my idea did involve an enabling HV call. Cheers, Ben.
