Hard to believe it's been 30 years!

One of the most interesting projects has been the PiStorm32 and Emu68 which enable the AMIGA to use a Pi as CPU accelerator with a baremetal ARM <-> 68k CPU emulator. Incredible CPU power but no access to the GPU and acceleration that could also boost graphics capabilities and applications via an RTG (Retargetable Graphics) access. The AMIGA OS is actively being developed (yes, still 40 years later) and AMIGA cross-compiler toolchains do exist for all kind of nowadays operating systems.

An experienced Mesa3D developer with and affinity/background for/on AMIGA that would be interested in porting an actual Mesa3D build to the PiStorm32/Emu68/AMIGA OS combo. Yes, 30 years later where it originated from. We have been collecting some funds as we know that this is not a weekend job but maybe someone is looking to for a challenge where „this is impossible“ gains your interest.

I'm not familiar with PiStorm32/Emu68 but the first big issue may be 
that Mesa makes pervasive use of 64-bit datatypes (int64_t, uint64_t). 
Just from its name, PiStorm32/Emu68 sounds like a 32-bit environment. 
So unless your compiler has good support for emulating 64-bit types with 
32-bit operations, you may be out of luck.
