[B2-devel] Planning for SheepShaver 2.3

[Gwenole B. <gb....@fr...>]

Hi,

We can also release a SheepShaver 2.3 soon. Issues left:

General:
- Audio is not automatically enabled with NewWorld ROMs and MacOS >=3D=20=

8.6. There are workarounds through the "Audio" control pannel IIRC. So,=20=

that's not release critical.
- Ethernet doesn't work in DIRECT_ADDRESSING mode yet.
- We need to find a way to sanely abort if people are trying to use=20
MacOS < 8.5 with NewWorld ROMs. Or is it supposed to work?

MacOS X:
- I have no news for the Tiger problems.
- There is no GUI nor CoreGraphics used yet. That's not important to=20
make a release since we can link with libSDL.a.
- Add support for Mach/i386 relocations to dyngen to have JIT working=20
on x86.
- Build with -mdynamic-no-pic.

Windows:
- Fullscreen DGA doesn't work
- Integrate new GTK+2 based GUI

I committed some important bug fixes recently which improves stability=20=

everywhere. However, there may be regressions so some more testing=20
needs to be done. Especially for clean installs. I only have 8.1, 8.6,=20=

9.0 handy and I again forgot to bring back 7.1.2.

Again, spinning release candidates could bring more build/application=20
testers.

Since roadmaps are a hype thing to tell nowadays, here are the features=20=

planned for 3.0:
- Make InputSprockets work but I have absolutely no idea how.
- Now that SheepShaver reached a decent stability level in CVS, I could=20=

get back to the JIT in the future. AFAICS, it's not difficult to bring=20=

in a 2x speed increase and thus reaching 30% of native speeds. 40+ is=20
possible but I am not sure yet how/if the profiler will work correctly.=20=

;-) Just need some time to merge all current bits and experiments +=20
dump remaining techniques out of my head.
- Host CPU sw assisted OpenGL rendering. Easy to do but simply=20
boring/tedious to handle and check all thunks. Aranym people did it=20
though. I have to think again for hwaccel through 3D cards.=20
Synchronization won't be trivial and offscreen rendering is not really=20=

effecient IIRC and depends on certain cards+drivers.

Bye,
Gwenol=E9.=
