|Re: [hatari-devel] UAE 68030 MMU + prefetch + instruction and data cache emulation|

I've tested again.
Hatari now runs with MMU + 68030 cycle exact.
That's a good job.
This is the closest configuration for the Falcon emulation.
I've given a new try to xtasie and it works again (OK)
underscore demo still doesn't work (it was working with some previous
versions of hatari).
I also think it's related to cycles exact between DSP and CPU.

The MMU core freeze at startup (it doesn't start at all).
It reminds me a previous problem with an infinitite loop in the main
I've tried to start from the non MMU conf (it's OK) and activate the
MMU + reboot from the gui (it freeze)
I've tried also to boot directly with the MMU (with hatari.cfg) : it
In my case, I see that falcon boots until it reaches the memory test,
so there's a problem at this moment, I may have forgotten sthg while
merging the new cpu part.
Does it also stops at memory test for you ?
OK, it's now fixed ; as discussed with Toni, the run_mmu030 functions
needed some changes to count cycles depending on whether cycle exact
mode was used or not, as the opcode handlers don't return a number of
cycles in CE mode.
