Xen devel - Apr 2005 - [PATCH] [RESUBMIT] Clustered xAPIC and Unisys ES7000 patch

Here is a patch for clustered xAPIC and Unisys ES7000 support in Xen. To
turn the features on add CONFIG_X86_CLUSTERED_APIC and CONFIG_ES7000
defines to xen/include/asm-x86/config.h

I have restructured the patch to fit the APIC patch submitted by Natasha
a couple of weeks ago.

I''d like to get Intel''s ACPI/PCI patch checked in, then
upgrade the
remaining platform code to as close to Linux 2.6 as possible, including 
the mach-specific platform hooks. Those hooks make supporting these odd 
NUMA platforms a lot more palatable. :-)

We *do* want platform-support patches, but I don''t think the tree is 
ready for this one just now. Hopefully in a few weeks...

  Thanks,
  Keir

Yes, I agree that the Linux 2.6 hooks make it easier to support the
platform specific code otherwise it will be ifdef hell. :)

Is it possible to get a copy of this patch? Does the patch move the
ACPI/PCI code to Dom0? Is the APIC/IO APIC code too moving to Dom0?
