Otherwise, I wonder how difficult it would be to set up a framebuffer on the A64 like what was done with Richard's rpi code. Chris

I paid scant attention to that issue, perhaps being old enough to consider (wrongly, in the case of the Plan 9 user space) that graphics are not indispensable. I do recall, vaguely, an Olimex comment about graphics being more accessible, but I did not make a note, the little that stuck was that some hardware manufacturer had embraced a slightly better standard than VESA, or some such. There may be some hardware out there that does not have "closed" graphics. In a perfect world, that would be an opportunity, but it seems we're not there yet, Lucio.

i have heard the name olimex in this context, too. a big problem with all alternatives is often that graphics or video decoding require binary firmware, or work only on linux, and no documentation exists from the chip vendors. i think generally there's a lot of low-power linux stuff to chose from, but once you plan to port plan9 to it, the fragmented nature of the arm platforms becomes a problem. no free lunch :(
