NetSurf 68k and JIT on AmiKit 8.1

Leandro Jardim · 21 March 2015, 05:45

NetSurf 68k halts with a GURU requester near the end of its loading when I start WinUAE with JIT disabled on AmiKit 8.0+. With JIT enabled it works correctly. With cycle-exact enabled it never works.

I tried also with my custom hdf NetSurf installation and the result is the same.

With WinUAE 2.8.1 without JIT, NetSurf works only with 68030 and up.
With WinUAE 2.3.0+ without JIT, it seems to work only with 060.

Sorry but I can only say: totally not enough information!

- no program version
- no configs
- no logs

(and my guess is simply bug in program)

Hmm! Seems it needs a MMU to run properly on "030 Cycle Exact"... Not only that, but to run on "030 Non-Cycle Exact" it needs that I turn off "More compatible" and turn on "Unimplemented FPU emu".

Sorry, what I meant is that it needs a MMU to run properly on "030 Cycle Exact" *and* it needs too that I turn off "More compatible" and turn on "Unimplemented FPU emu"...

But now came to my mind, when I was ready to generate the config files and logs, that the option "More compatible" is ghosted when there isnt any accelerator board selected, however it can be "toggled" on/off when I select a accelerator. Thus before the accelerator board was implemented, was impossible to run NetSurf with the recent additions to WinUAE core, because the option would be always ghosted and the option is selected by default...

At last that is what I got when I ran B12, and selected Blizzard 1230 with "cycle exact" turned on.

Is this correct, and you would "let" I generate the logs for a more complex configuration (without accelerator versus with accelerator), even knowing it is more trouble for you?

Sounds more like timing change causing the difference. NetSurf most likely is very multi-threaded.

Just tested NetSurf 3.4 Dev 2 on WinUAE 3.2.0 beta 17 AmiKit 8.5 030/040
With MMU/Cycle exact/Unimplemented FPU/More compatible/JIT and without.

It worked in every setting.
