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. | ||
19 | |||
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. | ||
27 | |||
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. | ||
31 | |||
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. | ||
