# HG changeset patch # User Dan Smith <danms@us.ibm.com> # Date 1202243439 28800 # Node ID e6d442b5bf122889708e9ad24545ae0b42b8c3bb # Parent f8ee9b04d92abf1d74bf4c72fac1f3a4128923dd Make the ProcRASD show CPU pinning information This is done by embedding instances of the physical processor objects into the HostResource[] field of the ProcRASD (per the MOF). In order for the linkage to be present, you need sblim-cmpi-base.
