- Change the way attach and open works to allow multiple audio
devices.
- Split the mulaw.c file into two to avoid dragging in mulaw
convertsion when they are not needed. Add 16 bit alaw/mulaw tables.
- Change the way audio properties are gotten.
- Recognize more versions os SoundBlaster.
- Add grfvideo_mode->disp_flags to select interlace, doublescan,
sync-on-green and horizontal/vertical sync polarity.
- Add some constants for grfvideo_mode->disp_flags.
This fixes a wrong output from grfconfig /dev/grf[23]
- changes for the grfconfig interface:
- Remove gv->hblank_stop and gv->vblank_stop.
- Only print doublescan and interlace flags. Horizontal/vertical sync
polarities are not yet supported and sync-on-green will never be
supported.
- Remove gv->{hblank_stop,vblank_stop} and use the other grfvideo_mode
values to set ba->data.
- Add gv->disp_flags to select interlace.
- Not yet supported are: doublescan, sync-on-green and the horizontal/vertical
sync polarity.
This makes it possible to use xfree values for grfconfig.
- changes for the grfconfig interface:
- Remove gv->{hblank_stop,vblank_stop} and calculate HBE and VBE from
gv->{htotal,vtotal}.
- Add support for gv->disp_flags to select interlace, doublescan and
horizontal/vertical sync polarity.
- Return EINVAL for gv->disp_flags and sync-on-green.
This makes it possible to use xfree values for grfconfig.
- Use interrrupt #6 instead of #2. #6 is the default interrupt and there
seems to be a problem with Cyberstorm 060 and #2.
- Set the interrupt register before enabling the interrupt.
- GC M2INS
- minor cleanup
- Switch from +hsync/+vsync to -hsync/-vsync.

XXX This (the m68k FPE, not the glue code) is known to be broken for
68LC040/68040V and 68LC060 cpus. This is also the reason we don't
bother to add options FPU_EMULATE to the DRACO configuration file, as
DraCos only come in 68040V (very few) and 68060 variants.

renamed AUDIO_ENCODING_SLINEAR and AUDIO_ENCODING_LINEAR reverts to the
NetBSD 1.2 sematics. A kernel with COMPAT_12 defined will accept
AUDIO_ENCODING_LINEAR and treat it as before, without COMPAT_12 it
will be rejected.
Correct handling for Trap #2 in SunOS executables,
now that we know it is supposed to flush the cache.
(Was thought to be "some obscure FPU operation".)
an 68060/68LC060, possibly switching on the 68060 FPU, instead of trusting
the value passed from the ROM OS to us by the bootblock.
Most 68060 boards, unlike the DraCo (which seems to have heavily patched OS
ROMs) don't set the AMIGA_68060 flag; instead, upon detecting an 68060, its
FPU is disabled to make the ROM scheduler work, and at a much later time (at
least, later than bootblock booting time), the "68060.library" installs the
Motorola 68060 software support, patches the scheduler for the 68060 FPU, and
re-enables the FPU.
Maybe this will be fixed one day, if Amiga International sells upgraded OS
ROMs which know about the 68060. Until then, and for legacy machines, this
kludge is needed if we want to boot a non-DraCo 68060.
Btw, thats why this is NOT in std.amiga, but in GENERIC; the DRACO
configuration doesn't need it (and I still plan to make std.draco go away).
