  13 1. State of Supported Hardware
  14
  15   PowerSurge Architecture - tested on UMAX s900, Apple 9600
  16     The second processor on this machine boots up just fine and
  17     enters its idle loop.  Hopefully a completely working SMP kernel
  18     on this machine will be done shortly.

  20     The code makes the assumption of only two processors.  The changes
  21     necessary to work with any number would not be overly difficult but
  22     I don't have any machines with >2 processors so it's not high on my
  23     list of priorities.  If anyone else would like do to the work email
  24     me and I can point out the places that need changed.  If you have >2
  25     processors and don't want to add support yourself let me know and I
  26     can take a look into it.

  28   BeBox
  29     BeBox support hasn't been added to the 2.1.X kernels from 2.0.X
  30     but work is being done and SMP support for BeBox is in the works.

  32   CHRP
  33     CHRP SMP works and is fairly solid.  It's been tested on the IBM F50
  34     with 4 processors for quite some time now.
