[B2-devel] AmigaOS: changes committed

[L. <jue...@t-...>]

Hi,

I just committed some changes to the AmigaOS port.

Video depth/resolution switching should now work. 
This is tested with Window output and CyberCFX screen output. Since I haven't Picasso96 installed here, I couldn't test that setup here.

The inherent limitations for the video modes are not yet fully enforcerd.


Another small change (asm_support.asm) enables interrupts at the beginning of system traps. 
This fixes a sound problem with MacOS 8.1 - in audio.cpp, the "AddSource" call to the Apple Mixer always returned error -624 and sound output didn't work at all.
This fix might not be a final solution.


Regards,
Jürgen

Thanks! :-)

I will try it under P96 at home.

This doesn't look correct to me. The supervisor bit shouldn't be cleared,
neither should there be any reason to explicitly enable interrupts.

-624 is interruptsMaskedErr which seems to only happen on LockMemory() or
LockMemoryContiguous(). Still I think that the problem is somewhere else.

Bye,
