Quoting Gordan Bobic <email@example.com>:
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) and
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.
It does seem outlandish, but it is kind of cool. Is it going to give
enough 3d speed? The next gen tegra is supposed to have a 24 core GPU.
It is probably more sane then my idea of just having a test suite from
digital video out -> digital video receiver/capture card to get known
test results. Then you could set up a hinted genetic algorithm based
on a comparison. It would only work with digital video signals though.
