Hi everyone,
For those of you interested in the progress of Solaris on OpenBIOS, I'm pleased to report the following output from SVN trunk (r886) with the attached patch applied (this is because the OpenSolaris 10 kernel seems to want quite a lot of run-time memory - more on this later):
Solaris 9 installation CD:

A couple of things that will be of interest to other developers:
- Solaris 9 seems to get stuck in a tight loop at the bottom of memory and doesn't want to proceed any further.
- In order to get Milax to boot this far, I had to keep increasing the memory requirements (and as you can see, it still wants more). There is a lot of MMU mapping activity, and so I suspect most of the dictionary space is being used to update the translations properties. We really need to optimise OFMEM so that it doesn't keep allocating new space from the dictionary all the time which should help reduce this immensely.
- Building with -O0 rather than -Os breaks Milax boot (the new SAVE_CPU_STATE handler falls over). This suggests that the stack is getting clobbered somewhere - Igor, any pointers on this one?
But all in all, I think we're looking quite good :)
ATB,
Mark.
