I'm running 2.6.10 on a ppc64 machine with 4GB of memory.
We're debugging an issue and would like to try and see if disabling the
U3 DART makes the problem go away. Unfortunately, this particular blade
is unstable if not all the memory banks are populated.
After some frustration I looked at the code and realized that the "mem="
functionality is not supported for ppc64 on this particular kernel.
Can anyone give me some advice on the simplest way to limit this thing
to under 2GB of memory so that the DART is not allocated/used?
Does anyone know when support for "mem=" was added? I know it is there
in the current git version, but the "powerpc" consolidation means
everything is all different now.
Thanks,
Chris
