Right now it still works as an "effect" (as Jeffs original extension
did), i.e. you have to select what you want to generate G-code for and
then run the gcode effect on that selection. But eventually I think it

Magma is a codename of certain RTAI development branch...
https://www.rtai.org/index.php?&MMN_position=1:1
there were names like Vesuvio, Kilauea and such... they simply specify
a code branch much like when we talk about 2.4 and 2.6 kernels.

Does it work as as an export pluging for gcode, right?
Z-axis? so, it can use a real paintbrush or engrave illustrations with
varying tool depth depending on line width?

Hi all,
Thanks for the help so far on building an smp kernel. I think I understand
the basic process of building a kernel, selecting the features I want in the
kernel, and building a kernel with the rtai extensions. I am still a bit
lost however on the exact versions of kernel and rtai code to use
Hello all,
I just wanted to share one of my recent late-night hacking outcomes. I
recently started looking into G-code generation of various kinds, and I
stumbled across Inkscape and Jeff Epler's gcode extension, and his work
on biarcs. I started playing around and eventually got the extension
make.conf perharps in /etc/?

and "prescott" is P4, the same P4 where the hyperthreading was
invented, the same ISA is in the Atom.
And the other Atomium is in Belgium.

Alex,
What it says is this:
"For non-SMP systems, disable symmetric multi-processing support:
Processor type and features ---> Symmetric multi-processing support --->
disabled"
So I do the reverse because it is an smp system. At least that is how I read
it.

Those instructions are not for SMP, they specifically disable SMP support.

Alex,
I did a pastebin of dmesg following boot of the kernel where I selected
586/K5/5x86/6x86/6x86MX for the processor family:

It clearly seems to detect only one processor.
The regular debian kernel correctly detects 4 processors. I am not sure what

John,
You are correct, SMP support is right above the selection for processor
family and was enabled for all three kernels. Under the Debian Lenny stock
kernel the same board shows 4 processors and 2 CPU Cores.
Likewise the standard rtai kernel used by EMC and the three kernels I built
all show a

I heard you need magma-smp
It would be interesting to see the first few lines from dmesg on one of the
kernels.
Does it detect it correctly?
Try a regular debian smp kernel (not sure what the package name is ..
probably something like linux-image-*-smp or so).

Alex

Ok, I added a hard drive, installed Debian Lenny and was able to follow the
instructions here:

I built three kernels, using processor family selections of
