No sweat. No, I mean a Zilog driver "in the Hypervisor" so you can get console :) I'd borrow the linux code.Since we are interested in zilog for PPC (use a lot by apple) we have had some luck with a driver that came with maria's patch: http://lists.xensource.com/archives/html/xen-ppc-devel/2006-05/ msg00028.html I only ask that we work together and not have 3 99% identical zilog driver like linux currently has. PROLL does not emulate Zilog. It only sets up the OF tree and leaves the OS free to use it. So, PROLL's code is fairly useless for your purpose. OpenBIOS, I do not know. But I do not see any need to emulate zs at all, if you plan for paravirtualization. Just add a driver to Linux for some kind of /dev/hvc (bonus points for making it compatible with PPC64). the Doms will just use hcalls. -JX _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
