Nope, you are confusing things. 1, 1A, 1B: 32-bit only processors. Move along. 2, 2A, 2B, 2C: 64-bit but extra instructions conflict with official MIPS opcode assignment. ``Oops''. Hard to find, if at all, nowadays. 2D: I'm not sure it has even shipped. 2E: found on the first Fuloong generation; might run OpenBSD/loongson, some tinkering work probably necessary, impossible to find at least in Europe (in other words: I have not been able to get one, therefore I can not confirm it works, and I won't bother unless one 2E system shows up in my mailbox or on my doorstep). 2F: found on the currently available systems: Fuloong 2F (6003, 6004), Yeeloong laptop, Linloong all-in-one PC (with 17" LCD). All these systems are supported, a not-so-insignificant number of our developers have one, and they work well. 2G: fixed 2F without the branch prediction bug. I am told the recent Yeeloong and Fuloong are fit with 2G processors. I am not even sure these can be told apart in software, as 2G supposedly reports itself as a 2F level. 3A: the long-awaited new generation. Supposed to ship in Q3 2010, then S2 2011, then S1 2012, then ``anytime soon''. I know that the GCC compile farm has two dekstop 3A motherboards, and one of the FreeBSD/mips mailing list subscribers has got one about two weeks ago, too. I have no idea how he got his, given that the systems are still not available to mere mortals. I am not expecting such systems to be available until next year (and I'd really like to get a motherboard, rather than yet-another-laptop-which-keyboard-will-die-after-two-months, but beggers can't be choosers).
