So, lots of people are asking me about 64-bit support for MIPS Linux. And this is something I think I know, but I'm not sure. And before I go spreading any more bad data, I thought I'd ask the experts. :) As I understand it, 64-bit support is really two different things: 64-bit data path (i.e. unsigned long long) and 64-bit addressing (for more than 4G of RAM). 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? I suspect that this is very much a toolchain issue, as I don't think gcc will generate 64-bit addressing code. Comments? Corrections? Smack-downs? :) Matt -- Matthew Dharm Work: mdharm@momenco.com Senior Software Designer, Momentum Computer
