That should be a good starting point. Do you mean the last patch he sent to us or are there some earlier unapplied patches? The last patch _seems_ to be mainly refactoring and disabling features which are not presented in certain models. I might have missed something of course: the patch is large. For me is also interesting what do we miss in the microSPARC implementation. If I switch off POST (which crashes due to the known FPU problems) LX/CX/X OBPs hang. Looks like it's expecting some interrupt (the SS-5 OBP escapes a similar endless loop on a timer irq), but not getting it. Do you know anything obvious qemu is missing in LX machine? -- Regards, Artyom Tarasenko solaris/sparc under qemu blog: http://tyom.blogspot.com/
