Re: [hatari-devel] Hatari and OUTSIDE (virtual memory manager)

[Uwe Seimet <Uwe.Seimet@xxxxxxxxx>]

Hi,

OUTSIDE does not crash anymore when being started, but it still does not
work. When starting NVDI Hatari freezes, does not even react when
pressing F12. Even Ctrl-C could not kill it, I had to use the kill
command. Without NVDI OUTSIDE can be started, but the system is not
stable, often there are double bus faults.

ROMSPEED now crashes Hatari:

#0  0x00007ffff5b81fa0 in raise () from /lib64/libc.so.6
#1  0x00007ffff5b83b7d in abort () from /lib64/libc.so.6

I noticed that this code fragment:

if (eamode == 0 || eamode == 1 || eamode == 3 || eamode == 4 || eamode =
= 6 || (eamode == 7 && rreg > 1))

is present in cpummu030.c and also in newcpu.c, but the changes only refer to
one of these files?

When testing I had both prefetch and cycle exact enabled.

Best regards

Uwe
