Titan 1.2 is available since quite a while - the dust on my board is
proof ;-) Since Titan 1.0 and 1.0 were shipped in very low numbers to
early customers only and will never be available in volume production the
support for them was removed. As I recall there were at least these
problems with Titan 1.0 and 1.1 in Linux:
- Linux uses the prefetch prepare for store operation.
- Coherency mode 5 which is mandatory for good performance and any kind
of sanity on SMP is now being used.
- The problem with the third ethernet port which Manish just had
described.
You can dig through XCVS, WebCVS or the linux-cvs archive to find where
I broke backward compatibility.
