[Xen-devel] [PATCH RFC v2 0/2] linux/vnuma: vNUMA PV guest support introduction

[Elena Ufimtseva <ufimtseva@xxxxxxxxx>]

This patchset introduces vNUMA for PV domU guest.

Enables PV guest to discover NUMA topology provided by Xen
and initializes NUMA topology on boot. XENMEM subop hypercall
is used to retreive information from Xen. Xen provides number 
of NUMA nodes, memory regions (start and end pfn) constructed 
based on e820 domU map, distance table and cpu to node map. i
xen_numa_init is called to setup NUMA related structures. 
To enable this mechanism, kernel should be compiled as PV guest
with CONFIG_NUMA=y and Xen should support vNUMA functionality 
(patchset 
http://lists.xenproject.org/archives/html/xen-devel/2013-09/msg01337.html ).
