  "message": "ppc/spapr: fix drc index mismatch for partially enabled vcpus\n\nIn case when vcpus are explicitly enabled/disabled in a non-consecutive\norder within a libvirt xml, it results in a drc index mismatch during\nvcpu hotplug later because the existing logic uses vcpu id to derive the\ncorresponding drc index which is not correct. Use env-\u003ecore_index to\nderive a vcpu\u0027s drc index as appropriate to fix this issue.\n\nFor ex, for the given libvirt xml config:\n  \u003cvcpus\u003e\n    \u003cvcpu id\u003d\u00270\u0027 enabled\u003d\u0027yes\u0027 hotpluggable\u003d\u0027no\u0027/\u003e\n    \u003cvcpu id\u003d\u00271\u0027 enabled\u003d\u0027yes\u0027 hotpluggable\u003d\u0027yes\u0027/\u003e\n    \u003cvcpu id\u003d\u00272\u0027 enabled\u003d\u0027no\u0027 hotpluggable\u003d\u0027yes\u0027/\u003e\n    \u003cvcpu id\u003d\u00273\u0027 enabled\u003d\u0027yes\u0027 hotpluggable\u003d\u0027yes\u0027/\u003e\n    \u003cvcpu id\u003d\u00274\u0027 enabled\u003d\u0027no\u0027 hotpluggable\u003d\u0027yes\u0027/\u003e\n    \u003cvcpu id\u003d\u00275\u0027 enabled\u003d\u0027yes\u0027 hotpluggable\u003d\u0027yes\u0027/\u003e\n    \u003cvcpu id\u003d\u00276\u0027 enabled\u003d\u0027no\u0027 hotpluggable\u003d\u0027yes\u0027/\u003e\n    \u003cvcpu id\u003d\u00277\u0027 enabled\u003d\u0027no\u0027 hotpluggable\u003d\u0027yes\u0027/\u003e\n  \u003c/vcpus\u003e\n\nWe see below error on guest console with \"virsh setvcpus \u003cdomain\u003e 5\" :\n\npseries-hotplug-cpu: CPU with drc index 10000002 already exists\n\nThis patch fixes the issue by using correct drc index for explicitly\nenabled vcpus during init.\n\nReported-by: Anushree Mathur \u003canushree.mathur@linux.vnet.ibm.com\u003e\nTested-by: Anushree Mathur \u003canushree.mathur@linux.vnet.ibm.com\u003e\nSigned-off-by: Harsh Prateek Bora \u003charshpb@linux.ibm.com\u003e\nReviewed-by: Nicholas Piggin \u003cnpiggin@gmail.com\u003e\nSigned-off-by: Nicholas Piggin \u003cnpiggin@gmail.com\u003e\n",
