I suppose you could say that. I think I saw someone post to this list that they were working on a patch to enable 64 bit registers with a 32 bit kernel. > My understanding is that "MIPS64" generally refers to a kernel which > supports a 64-bit data path, but we're still limited to 32-bit addressing. > Is that correct? The mips64 tree in CVS is one that is a 64 bit addressing capable kernel. AFAIK the linx convention is that <foo>64 refers to addressing (which probably impiles register width too :>) I'm not sure what the current state of the ELF64 MIPS toolchain is. Jason
