Re: Lets actually try Hybrid Emulation
The cause for the crashes (8000 000B) are the mathlibs, which may try to use calls for the 68881/68882 that isn’t available. 68040.library traps those calls that aren’t available on 040 and perform them in software instead (essentially 68881/68882 emulation). There are mathlibs that do not use FPU, and hence will not cause such problems - I wonder ...

Re: Lets actually try Hybrid Emulation
I tried using the 3.1.4 ROM from Hyperion and the Workbench that comes with it, but it still had the problem with clicking icons even though the install disk should have a 68040 library. OS 3.1.4 does NOT come with 68040.library, you are supposed to install CPU libraries from CPU card provider - or the CPU libraries from ThoR (MMULib). Running Ami...

Re: Lets actually try Hybrid Emulation
OK, here is a new core and kernel module. http://www.64kib.com/minimig_irq_core.tar.gz Where do I find the sources for this module? As I wrote earlier, I build my own kernels, and hence the "magic version" is different than the "official" kernel :) /root# insmod /media/fat/Amiga/minimig_module/minimig-irq.ko insmod: ERROR: coul...

Re: Lets actually try Hybrid Emulation
So JIT and MMU? In other 68k emulators those have been mutually exclusive - either super fast JIT or relatively slow “non JIT”, but with MMU.

Can’t expect too much when emulating full 040 with MMU and (hence) no JIT

Re: Lets actually try Hybrid Emulation
Regarding the 68040 libraries, I think the problem with the mmulib ones are either the mmu, or perhaps that it tries to “fix” known issues with the real 68040s that aren’t necessarily there with a software emulated 68040…

Re: Lets actually try Hybrid Emulation
I wanted to ask earlier, what is the reason for using system mode? Normallly, system mode is used for emulating a particular hardware configuration in addition to CPU, but is that really the case here? Thinking a little more, I suppose it is - interfaces to the real hardware only exists in system-mode I guess :) Btw - I am ready to try out the new ...

Re: Lets actually try Hybrid Emulation
Noone really has a working setup yet, we are all experimenting. Btw you don’t need ssh, you can just press F9 in the menu core, log in and start the 68k emulation from there, after for example a 20 sec sleep, enough so you can F12 and start the hybrid core before CPU emulation kicks in.

Re: Lets actually try Hybrid Emulation
Some first impressions... :) * turned off PPP, set UART to "none" (does it matter? I see no difference really) * more or less untampered OS 3.1.4.1 * turned off Minimig RTG, use P96 with "native" driver and HD720 mode (32 pens) * installed CPU libraries (+ mmu.library - http://aminet.net/package/util/sys/Mu680x0Libs) * with musa...

Re: Lets actually try Hybrid Emulation
I have some test code that was used to find bugs in tg68, which surely can be used again, and also software that use FPU... what kind of precision can we expect?

Re: Faster CPU for Minimig core?
Just thinking outside the box (literally)... What's the capability of the IO header on the DE10-Nano? It's fast/capable enough for SDRAM; would it be fast enough for a RAM+CPU board, like we used to have in trapdoor expansion for amiga 1200 and the like? i.e., for those who really want a faster CPU in their simulated amiga, would it be feasible fo...

Re: Faster CPU for Minimig core?
sounds like what some people really want are 68k MMU and FPU. and if you’re running amigaOS both are mostly irrelevant. Not really - FPU is supported and is used when available, by OS libraries. But that is really beside the point, which is that there is plenty of SOFTWARE that not just use FPU, but sometimes require FPU. If all you want to use Am...

Re: Faster CPU for Minimig core?
Back in the days (mid 90ies) some fellow computer student friends and I concluded that the probably easiest and cheapest way for us to get faster Amigas, would be to use mind altering drugs that changed our own perception of time - maybe something to consider, hehe

I just see his tg68 spin-off that he calls m68k which he has put on github already, which is more like a 020... nothing about 040/060. I see kol...

I have dockerfiles for building kernel and firmware, building the minimig core is still a “manual” job that takes place in Windows (AFAIK).

Re: Faster CPU for Minimig core?
FEMU works, but is super slow (using the math libraries). What potentially could be done, is to use FEMU as a starting point for FPU emulation on the ARM processor.

Re: Faster CPU for Minimig core?
So nobody here misses a CPU with MMU capabilities? That's at least my main takeaway from this thread so far. I don’t miss it because I have that with software CPU emulation, I don’t see much point in implementing it on FPGA. The memory of the MiSTer is already quite different than old “classic” fast page RAM, so it is doubtful you can even do in a...

Re: Faster CPU for Minimig core?
Fast 68k CPU + ECS/AGA on FPGA is the only useful hardware config missing, and that is easiest done by moving CPU to the ARM using JIT software emulation.

Re: Faster CPU for Minimig core?
Not so, AMIX also runs on A2000 with A2620 or A2630 cards, Commodore even shipped these as A2500UX.
