Re: RTLinux and mvme26xx cards?

Hello,

I seem to be hitting a build problem with the 2.4.-test kernels so I may
not get to try it out. I popped a note to the list yesterday (see 'can't
compile 2.4.0-testx kernels on G4 YDL C.S. 1.2.1') describing my build
errors. I haven't figured out why I can't complete compilation. I was going
to try your 2.4.0 config and patches/vme drivers, then try a fresh
2.4.0-test1 kernel ( based on an email I got) and then play with RTLinux.

Someone sent me an email about using /arch/ppc/boot/zImage which worked on
our boards as well without your patches. From the mail archives I think you
do the memory mapping differently than what is included in the kernel as
well as a different boot loader. Can I get a little more insight on what
your patches are providing.

Thanks,
JH

Hello,

what is the possibility of using FSMLabs RTLinux on mvme26xx boards? IIRC
RTLinux supports uniprocessor powerpc in the V3 beta series, correct me

I'm wrong. Using Gabriel's patches I have been able to bring up 2.2.12
series kernels on our mvme2604 boards. I'm having problems on with the
2.4-test series kernels and Gabriel's patches, issue with NFS, but I'm
starting to wonder about using RTLinux on these boards.

I have never found time to try RTlinux, but I wanted to. I don't
foresee any major problem, except perhaps for interference with my VME
driver (the Universe actually has to act as a cascaded interrupt
controller).
