[PATCH] nr_cpus calculation problem due to incorrect sockets_per_node
Testing on an 8-node 128-way NUMA machine has exposed a problem with
Xen''s nr_cpus calculation. In this case, since Xen cuts off recognized
CPUs at 32, the machine appears to have 16 CPUs on the first and second
nodes and none on the remaining nodes. Given this asymmetry, the
calculation of sockets_per_node (which is later used to calculate
nr_cpus) is incorrect:

VGA passthrough and AMD drivers
Hi all,
I have made some tests to find a good driver for FirePro V8800 on windows 7 64bit HVM.
I have been focused on ''advanced features'': quad buffer and active stereoscopy, synchronization ...
The results, for all FirePro drivers (of this year); I can''t get the quad buffer/active stereoscopy feature.
But they work on a native installation.
