Dear Mesa dev community,
Please let me apologize if you consider this off topic but I think that this is
probably the audience that could help in reviving and getting back to the roots
where Mesa3D originated from.
To use Brian Paul’s words:
The core library was originally (started in 1993) written on an Amiga using the
DCC compiler. Later, development was moved to an SGI workstation. Current
development is done on PC/Linux systems.
Hard to believe it's been 30 years!
So thirty years later the AMIGA community is still huge, growing and the development
on hardware and software accelerators is giving us new capabilities. 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.
So what are we looking for? 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.
