[PATCH] nr_cpus calculation problem due to incorrect sockets_per_node
...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:
pi->sockets_per_node = num_online_cpus() /(num_online_nodes() *
pi->cores_per_socket * pi->threads_per_core);
The most straightforward solution is to remove sockets_per_node, and
instead determine nr_cpus directly from num_online_cpus.
This patch has been tested on x86_64 NUMA machines.

[PATCH 5/6] xen, tools: calculate nr_cpus via num_online_cpus
Once Xen calculates nr_nodes properly, all nr_cpu calculations based on
nr_nodes * sockets_per_node * cores_per_socket * threads_per_core are
broken. The easy fix is to replace those calculations with a new field,
nr_cpus in physinfo which is calculated by num_online_cpus(). This
patch does so and attempts to change all users over to nr_cpus field in
physinfo. This patch touches arch/ia64/xen/dom0_ops.c, but I''ve not don...

xl: expose max_cpu_id from `xl info`

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.
The only driver that allows
