| 1. State of Supported Hardware |
| |
| PowerSurge Architecture - tested on UMAX s900, Apple 9600 |
| The second processor on this machine boots up just fine and |
| enters its idle loop. Hopefully a completely working SMP kernel |
| on this machine will be done shortly. |
| |
| The code makes the assumption of only two processors. The changes |
| necessary to work with any number would not be overly difficult but |
| I don't have any machines with >2 processors so it's not high on my |
| list of priorities. If anyone else would like do to the work email |
| me and I can point out the places that need changed. If you have >2 |
| processors and don't want to add support yourself let me know and I |
| can take a look into it. |
| |
| BeBox |
| BeBox support hasn't been added to the 2.1.X kernels from 2.0.X |
| but work is being done and SMP support for BeBox is in the works. |
| |
| CHRP |
| CHRP SMP works and is fairly solid. It's been tested on the IBM F50 |
| with 4 processors for quite some time now. |
