Revision f32393c943e297b8ae180c8f83d81a156c7d0412 authored by Nathan Fontenot on 30 April 2015, 01:42:06 UTC, committed by Michael Ellerman on 01 May 2015, 03:47:24 UTC
The incorrect ordering of operations during cpu dlpar add results in invalid affinity for the cpu being added. The ibm,associativity property in the device tree is populated with all zeroes for the added cpu which results in invalid affinity mappings and all cpus appear to belong to node 0. This occurs because rtas configure-connector is called prior to making the rtas set-indicator calls. Phyp does not assign affinity information for a cpu until the rtas set-indicator calls are made to set the isolation and allocation state. Correct the order of operations to make the rtas set-indicator calls (done in dlpar_acquire_drc) before calling rtas configure-connector.
