I've comited a more simple version of the fix.
No need to add the "dsp_core.interrupt_state == DSP_INTERRUPT_NONE"
when searching for a new interruption.
The patch is very easy now. I've just moved the 2 interruptions into
the main interruption routine.
Before, the hostport interruption was tested only after a DSP or host
read or write, but the interruption can happen as soon as the buffers
are empty or full.
Now, I just do the test after each DSP instruction.
I've done many tests with demos that I know use DSP interrupts, games
and music programs.
I didn't notice any regression with this patch.
Enjoy Lockup demo now ;)
It works now with DSP and shows 3D graphics, but I don't have any music.
Do you have music in it?
I tested many programs and only regression I
noticed was in Sidetracked music demo, it doesn't
anymore start, *even with older Hatari version*,
neither with TOS4 or EmuTOS, with or without MMU,
with Hatari default config or my own.
(Dry Egg game, which also worked only with EmuTOS,
does still work.)
I don't understand what could have changed, to
break that demo also with older Hatari versions.
Maybe it's wall clock sensitive?

PS. I'll push update to compatibility list &
release notes after I've done some additional
testing.
