Hi Airy,
I wouldn't be too sure about that. The usually well informed Heise
website (www.heise.de) reports that Panther will basically be a 32
bit OS which will use some 64 bit portions in dedicated areas (dsp
lib etc.). Over the time it should see a smooth transition to 100%
64bit.
Too bad I am not reading german, because I don't see how they indent
to do this.
All the systems I know that went 64 bits, did not choose the
progressive way. Either the kernel is 64 bits or the kernel is 32
bits.
And all the rest are logical consequences of that.
It's probably possible in MACH to support 32 and 64 bit processes;
so, things could migrate incrementally. I believe the kernel itself
would have to be 64 bit; so, kexts would have to be, too. All the
user mode drivers and plugs would probably need to be built both
ways...
