Large parts of the SPE extensions are implemented, most fixed-point operations (but the multiply and add family) and I think almost all floating-point operations (the flags are not properly emulated, for now). But there's a lack of a CPU model that would really use it. It could be made available very easily for a test CPU for user-mode only, as it is now. The MMU model used on Freescale cores is not implemented yet, then the full-system emulation would not be possible for now. > > - someone provide an open-source hypervisor, compatible with the ones > > used on real machines, that would allow at least Linux to be able > > to run > > on a CPU with hypervisor mode available. > > Does xen/ppc satisfy your requirement ? > Maybe Hollis will comment. I don't know really. I guess it may do for the more urgent need which is to have a fully "transparent" hypervisor that would enable the OS to access all resources. I won't bet it could be a replacement for IBM hypervisor software as the full specifications of this software have still not be fully released (the PPAR document, which describes the whole hypervisor features is still a draft). But it's a good idea, I may take a look of what it could provide. -- J. Mayer <[EMAIL PROTECTED]> Never organized
