I'm not quite a kernel developer, but for those interested I found these (eventually); Ross white paper for hypersparc processor: http://web.archive.org/web/19980515154249/bifrost.ross.com/pdfs/hyper.pdf Old Ross Hypersparc site from 1998: http://web.archive.org/web/19980211021424/bifrost.ross.com/hyprsprc.html I didn't have time to go through webarchive for newer versions, but it's a start. Regards.
