[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. -- Elizabeth Kon (Beth) IBM Linux Technology Center Open Hypervisor Team email: eak@us.ibm.com _______________...

[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...
