[Xen-devel] [PATCH 0/5] xl: allow for node-wise specification of vcpu pinning

[Dario Faggioli <dario.faggioli@xxxxxxxxxx>]

Hi all,

Take 3 of this series. It allows for specifying vcpu pinning taking NUMA nodes
into account. IOW, something like this:

Â* "nodes:0-3": all pCPUs of nodes 0,1,2,3;
Â* "nodes:0-3,^node:2": all pCPUS of nodes 0,1,3;
Â* "1,nodes:1-2,^6": pCPU 1 plus all pCPUs of nodes 1,2
ÂÂ but not pCPU 6;

All comments that v2 got have been addressed. In particular, the test script
has been rearranged and enhanced to match the requested behavior (generate a
test vector file and then read it).

Thanks and Regards,
Dario
