support for HIGH MEM and NUMA in zumastor built kernel #93

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Our current kernel configuration supports only 4G memory. Systems with
large amount of memory can't see the extra memory with zumastor kernel
installed. We may want to build separate kernels with 64G high mem
configured. We also want to investigate the performance and stability with
NUMA configuration and add that support if it is considered better.

That would disallow using them with vmware player, I suspect.  
Oh, well, I should learn how to use vmware server anyway...

What about building a 32-bit kernel and a 64-bit kernel? It's what I do for 
Ubuntu
Gutsy and I believe it works fine. I have not tested it on amd64 but given it's 
the
original Gutsy -server kernel config + ddsnap patches and options, I'd say it 
does.

That would be too obvious :-)

The NUMA issue is separate, please move that to a different bug.

Will is already building both 32 and 64 bit packages.  
64 bit should be the way we address the memory space for the 0.8 release, I 
think.
If some user requests PAE aka highmem packages, we can always do that too.
