I've seen your Qemu patches go through the list, but does this mean you have a patch for the OpenBIOS alarm word somewhere that we haven't seen yet?
Not sure I can even try this without working timers on sparc64 I think sparc (or maybe ppc as well) has good enough timer support so openbios can progress in implementing alarm word.
Do we have a test case for alarm word? Is it really useful?
In terms of the console, OpenBIOS currently doesn't use alarm interrupts there either - it just sits in a busy-wait loop checking an I/O port or similar to determine when a new character is incoming.
So we need i/o scheduler now (not critical at the moment) :)
Yeah, I can't get too excited about this. It's not as if BIOS routines are super-performance critical...
Forth profiler... not sure it is a good idea :)
