Do you want SMP MacPPC? Look over here, donations are needed!

Contributed by jj on from the Have-smp-will-donate dept.

Gordon W Klok (gwk@) is looking to start work on multiprocessor support for the MacPPC platform.

Update my request for a faster new world macintosh to a dual processor
machine.
martin@ reports macppc is very stable on his single processor Power
Macintosh 7600, where I can barely manage a cvs checkout on my 9500MP
or 9600MP so ask if someone can part with one of these.
Bret Lambert, who has previously helped coordinating donations of SUN Blade 1000 machines to kettenis@ and jason@, has agreed to coordinate this effort.

He's accepting donations on paypal bret.lambert@gmail.com.
If you have other questions about this donation effort, please email him on above email address.

As usual, if collected funds exceed what is necessary to get this machine, they will be donated to OpenBSD.

So for those of you who wants your dual CPU MacPPC machines to get SMP support, this is your chance, donate now!

    Out of curiosity, how much of SMP is machine-independent and how much must be re-done for each arch?

      The answer to both is "a whole lot."

      SMP is not only spinning up secondary processors and figuring out
      how to keep interrupts from stepping all over each other, it's
      making sure that data accesses and function calls in the kernel
      are thread-safe (grep src/sys for the MULTIPROCESSOR #define
      sometime).

      If gwk@ doesn't want it, I'd gladly take what you would have spent on shipping...

      I'm hoping to get $800 or so, in order to get a reasonably fast machine (faster machine -> more development -> that much closer to world domination), and I've gotten about $200 thus far.
