Probably, yes.

I've been thinking about how to use the cpuid hypercall.
Right now the x86 backend does
foreach proc
bind on this proc
do a lot of cpuid calls
It would do instead
foreach proc
cpuid hypercall on this proc
So we would
1) add a cpuid(topology, cpu, inputbuffer, outputbuffer) hook pointer in

I just checked the code. My only little complain is that we always get
this error message in the terminal, even when not enabling Xen:

Hello,
Can't check the code right now, but a couple questions below.

Hello,
Please find v2 of Xen support here:
http://xenbits.xen.org/gitweb/?p=people/andrewcoop/hwloc.git;a=shortlog;h=refs/heads/hwloc-xen-topology-v2
This branch contains a few of Brice's patches to export more functions
for plugins, as well as the main Xen patch which is a merge of various
13 matches
