Ocean machine (TBL) works too ;)

A very great news : Starstruck demo by TBL works under hatari now.
a bit slowly but it works ;)

By adding the follwing line, everything seems to work fine :


static void m68k_run_3p(void)
{
    struct regstruct *r = &regs;
    bool exit = false;
    int cycles;
printf ( "run_3p\n" );

retry:
    TRY(prb) {
        for (;;) {
#ifdef WINUAE_FOR_HATARI
            //m68k_dumpstate_file(stderr, NULL);
            if (LOG_TRACE_LEVEL(TRACE_CPU_DISASM))
            {
                int FrameCycles, HblCounterVideo, LineCycles;
Video_GetPosition ( &FrameCycles , &HblCounterVideo , &LineCycles ); LOG_TRACE_PRINT ( "cpu video_cyc=%6d %3d@%3d : " , FrameCycles, LineCycles, HblCounterVideo );
                m68k_disasm_file(stderr, m68k_getpc (), NULL, 1);
            }

            BusErrorPC = m68k_getpc();
            currcycle = 0;         <-- THIS LINE HERE

#endif
            r->instruction_pc = m68k_getpc();
            r->opcode = get_iword_cache_040(0);
            // "prefetch"
            if (regs.cacr & 0x8000)
                fill_icache040(r->instruction_pc + 16);



Maybe it should also be added into run_3ce

Nicolas, I let you accept this or not (it may noit be the correct fix).
If it's OK, you can fix it.

I've added the following line into m68k_run_3p() and m68k_run_3ce()

#ifdef WINUAE_FOR_HATARI
            /* Run DSP 56k code if necessary */
            if (bDspEnabled) {
fprintf(stderr, "currcycle = %d\n", currcycle); <-- this one ;)
                DSP_Run(2 * currcycle * 2 / CYCLE_UNIT);
            }
#endif

I get a huge value for currcycle, which explain why the DSP runs all the time.
Currcycle increase all the time to a huge value.

currcycle = 159398400
currcycle = 159398912
currcycle = 159399424
currcycle = 159399936

Maybe it is not reseted or something like that.

While testing, I've encountered another problem :

I was in Falcon mode, 68030, and I tried to switch to 68060
and hatari got freezed (no more F12, no more reset, ...)
This is fully reproducable even directly from GEM desktop.

If one disables sound (separate SDL thread for it),
this is where Hatari spends its time afterwards:
   49.01%   23187    hatari    [.] dsp56k_execute_instruction
   13.92%    6573    hatari    [.] dsp_jclr_pp
   13.45%    6361    hatari    [.] read_memory
    2.91%    1376    hatari    [.] DSP_Run
    0.00%       1    hatari    [.] get_word_cache_040
    0.00%       1    hatari    [.] do_specialties.isra.34
    0.00%       1    hatari    [.] do_specialties_interrupt.isra.32
    0.00%       1    hatari    [.] m68k_run_3p

I.e. Hatari is stuck in DSP emulation.

If I disable DSP emulation at same time I select 060,
CPU switch works fine.


You don't even need to switch CPU, just starting 060+DSP freezes:
$ hatari --tos tos404.img --machine falcon --cpulevel 6

I.e. to use 060, you need to disable DSP:
$ hatari --tos tos404.img --machine falcon --cpulevel 6 --dsp none
