UPDATE: we've not had many people confirm interest in this event yet,
which is a shame. If you would like to join us for this session,
please reply and let me know. If we don't get enough interest by the
end of Sunday (28th August), then we'll have to cancel the meeting.
Unfortunately there is no way I could make it, but on the subject of 3D
support on ARM, Luke recently mentioned something that initially seemed
outlandish but upon closer examination doesn't seem like a bad idea. As
we all know, the state of openness of specifications of commonly used
ARM 3D GPUs is at best dire. What has been proposed is a bit radical,
but it doesn't actually seem that implausible. Specifically, combining
Open Graphics Project (http://wiki.opengraphics.org/tiki-index.php
the xilinx zynq-7000 or similar (dual core Cortex A9 + FPGA). The idea
is to have an OGP GPU in firmware in FPGA. In terms of the power budget,
it seems to work relatively sanely considering what it is, and it is as
ideal as it gets as far as openness and flexibility goes.
I just thought it's worthy of a mention.
