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:
