[LLVMdev] Xilinx zynq-7000 (7030) as a Gallium3D LLVM FPGA target

[Luke Kenneth Casson Leighton]

i was just writing this:
http://www.gp32x.com/board/index.php?/topic/60228-replicating-the-success-of-the-openpandora-discussion-v20/

when something that just occurred to me, half way through, and i would
greatly appreciate some help evaluating whether it's feasible.

put these together:
http://www.xilinx.com/products/silicon-devices/epp/zynq-7000/index.htm
http://llvm.org/releases/2.7/docs/ReleaseNotes.html
http://en.wikipedia.org/wiki/Gallium3D#LLVM_usage
http://wiki.opengraphics.org

and it may be the case that completing the software for the
OpenGraphics Project is a matter of hitting "compile".  not only that,
but a fully FSF Hardware-Endorseable Laptop with decent 3D Graphics
Engine would be as equally simple (the only FSF Hardware-Endorsed
laptop product is that Loongson Leemote, by virtue of it having a 2D
PCI Graphics IC and a 900mhz MIPS).

the logic goes as follows:
* one of the Gallium3D targets is LLVM.
* one of LLVM's targets is Xilinx FPGAs (MicroBlaze).
* the zynq-7000 7030 has 125k FPGA Logic Gates (and more)
* with a TFP410 as the DVI driver, the OGP is done!

now, given that this appears to be "too easy", i'd really _really_
appreciate some help checking the facts.  and, also, if it turns out
to be feasible, assessing roughly what the performance might be.

also, most importantly: what am i missing? :)

many many thanks,
