From cc78d7ba0e64b870013ad7753c3d24cc88905712 Mon Sep 17 00:00:00 2001 From: Li Zhang Date: Fri, 15 Mar 2013 17:25:09 +0800 Subject: [PATCH] Remove contiguous CPU indexes assumption When getting CPUs' information, it assumes that CPU indexes are not contiguous. But for ppc64 platform, CPU indexes are not contiguous because SMT is needed to be disabled, so CPU information is not right on ppc64 and vpuinfo, vcpupin can't work corretly. This patch is to remove the assumption to be compatible with ppc64. Test: 4 vcpus are assigned to one VM and execute vcpuinfo command. Without patch: There is only one vcpu informaion can be listed. With patch: All vcpus' information can be listed correctly.
