Title: Minimig For Linux, Virtualization, 68040, CF
Post by: asian1 on September 09, 2007, 05:13:26 PM

Is it possible to use Minimig with Linux for 68K CPU?

http://www.linux-m68k.org/

Pano Logic had created Virtualization terminal based on FPGA. Is it possible to use reconfigurable Minimig as Virtualization terminal? (ie VMWare, Xen, Virtuozzo etc).

http://www.panologic.com/

What about X.Org multiseat or BeTwin or Buddy terminal?

What about putting DisplayLink chipset inside Minimig for VGC (Virtual Graphic Chipset) applications?

Is it possible to use faster 68040 or ColdFire CPU with Minimig?

Thank you.

Linux: No. It requires an MMU/FPU.
68040: No. It'll require a major rework.
Coldfire: No. It'll require a major rework plus coding a full 68000 compatibility layer.

uCLinux or NetBSD?

However the Minimig is clearly good for one thing - classic Amiga. No reason for modern operating systems in my opinion.

NetBSD has same requirements as Linux in regards to CPU.
If the MiniMig really is A500 compatible, uCLinux will already run on it.

@asian1:
* Pano logic's terminal lacks RAM.
* Coldfire => incompability problems.
* 68040, major rework. And actually only 68020+mmu or 68030 is needed for "unix".
However you could proberbly implemement some mmu and memory protection mode with the FPGA and add the needed code changes in NetBSD and make minimig run unix properly. This would not be particulary compatible however. Except maybe for m68k userland applications.

@Matt_H:
Actually asfaik, FPU is not a requirement. But at least for NetBSD/68k MMU is (and likely linux too).

You'd need at least a 68010 then.

Can we at least get the basic A500-level capability done first???

If the original poster feels like implementing this, it's fine. Personally I won't put any effort into it.
I agree on basic A500 OCS capability as the #1 priority. And within that DRAM + HDL cpu is good implementation candidates. Because that would eliminate the need for a specific Minimig board.
