booting soolaris8 with 128 processors
I'm simulating with simics a Multiprocessor with SPARC and Solaris 8 as OS.
I have a working configuration with 64 processors, but when I try to boot a configuration with 128 processor I get the following error :
panic [cpu149 ]/thread = 10408000 : add_softintr: exceeded 256 handlers
What I need to modify to allow this number of processors? It is possible?
Any idea?
Thank you very much.

Solaris 8? Since there were no physical 128 processor machines then, I'm assuming there's simply some hardcoded assumptions in either the boot code or the kernel that don't allocate enough space to use that many processors.
You'd probably need source code and modifications to make it work, but I have no idea how you'd get that for Solaris 8.
Any reason you're not trying this with OpenSolaris? There at least if you ran into issues you'd be able to examine or modify the source easily.

Thanks for the reply, I will try installing Opensolaris.Anyway, anybody knows an available patch, where the NCPU parameter changes, increasing the supported processors number.NCPU is defined in machparam.hThanks
