The Community you expect to review your project: ON 1.4.2. The ARC(s) you expect to review your project: PSARC - Open. 4. Technical Description SUMMARY: The Physical Resource Inventory (PRI) on sun4v systems is to be used as the source for building an FMA topology. This case adds interfaces to libmdesc so the sun4v enumerator can walk the hierarchy in the PRI and build an FMA topology. This case seeks patch binding for an ON10 Update release. PROBLEM: The current APIs in libmdesc are for directed queries when one knows apriori something about the nodes of interest. The sun4v platform independent enumerator, by virtue of being generic, cannot assume anything about the MD/PRI contents. New APIs are needed to allow the arbitrary walk of the MD/PRI graph. PROPOSED SOLUTION: This case adds new interfaces to the libmdesc library to walk the MD/PRI graph and perform a callback. The libmdesc library was initially introduced as part of the following cases: FWARC/2006/141 Logical Domains (LDOMS) 1.0 FMA FWARC 2005/116 sun4v core API PSARC/2004/515 sun4v_machine_class The interfaces being added are: Interface Classification ---------------------- --------------- md_walk_dag Project Private md_get_prop_arcs Project Private ISSUES: NONE REFERENCE DOCUMENTS: FWARC/2006/141 Logical Domains (LDOMS) 1.0 FMA FWARC 2005/116 sun4v core API PSARC/2004/515 sun4v_machine_class sun4v PI Enumerator FMA Portfolio http://wikihome.sfbay/fma-portfolio/Wiki.jsp?page=2008.015.sun4v_pi_enumerator 6.
