A few months ago, I talked about the x86gentopo
project - a reusable baseboard enumeration approach for x86 systems. It's the same spirit that drove the platform independent sun4v FMA work
Yesterday evening, the project integrated into OpenSolaris. If you missed the flag day message, here it is again.
If you don't use x86 systems, or don't care about x86 FMA, you can hit
There is a new x86 generic FMA topology enumerator available with the
PSARC/2009/490 x86 Generic FMA Topology Enumerator
6785310 Implement SMBIOS contained elements/handles
6841286 Need x86 generic FMA topo enumerator
6853537 x86gentopo needs OEM-Specific SMBIOS structures
6865771 Topology relationships should be derived from contained
handles & elements of SMBIOS
6865814 Chip enumerator should derive serials & labels using libsmbios,
if SMBIOS is FM aware
6865845 /dev/fm should export the Initial APICID, SMBIOS based ID/instance
to the chip enumerator
6866456 Generic Topology FMRI ereport
The new x86 generic enumerator creates physical topology, as well as
identity information (serial number, part number, etc...), for i86pc class
systems which contain a compatible SMBIOS. The X64 Platform Resource Management
Specification (PRMS-1) describes what a compliant SMBIOS is (currently in
uncirculated draft form).
To correctly diagnose faults the cpu and memory ereport generators have
been modified to report x86 generic topology, when a compliant SMBIOS is found.
If a compliant platform SMBIOS is not found, the x86 generic enumerator and
x86 generic ereport generators will revert to existing (legacy) enumeration
and ereport generation.
If a platform does contain a compliant SMBIOS and wishes to force legacy
enumeration, the kernel tunable variable x86gentopo_legacy can be set in
set x86gentopo_legacy = 1
To report bugs against the x86 generic topology enumerator and/or the
cpu/mem ereport generators please use the following product/cat/subcat:
solaris/fma/other : x86 generic enumerator
solaris/fma/mem : memory ereport generator
solaris/fma/cpu : cpu ereport generator
To report bugs against the SMBIOS structure use please use the following

Now to get that PRMS finalized and made public...
