Oracle Solaris 10 Update 9: FMA Fixes

6627041 Add a PSN nv-pair to the authority portion of the FMRI scheme
This may be less exciting to the end users, but my top favorite. This fix includes the product serial number (PSN) into the FMA fault telemetry. It's a key piece of information to improve the Oracle Auto Service Request (ASR) program. With the PSN, the "Auto" part of ASR is sped up. Hmm...maybe this is exciting for customers - you'll get a faster turn around time on parts servicing.
6502086 DBU errors should be diagnosed as HV defect/fault
6502089 ferg.invalid errors should be diagnosed as a fault
These two CRs provide a level of diagnosis for firmware issues on the sun4v systems. The first covers an error that should not happen unless there's a bug in the hypervisor. The second warrants a little explanation. On CMT systems, FMA telemetry is sourced in the SP - the hardware error is collected in the SP, packaged into an ereport, and provided to Solaris. If the error bits collected can't be mapped to a defined ereport, a "ferg.invalid" ereport is produced. Basically saying "There's been an error, but can't determine what kind". This shouldn't happen outside the lab. If it does, it indicates a logic flaw in the firmware on the SP.
6764337 Needs level 2 FMA compliance for chipset 5100 MCH
6889350 fma fails if DIMM sizes are mixed
A couple of fixes for various Intel configurations. The first enhancing FMA support to include another memory controller chipset. Oracle's CP3250 blades use the 5100 chipset. The second here fixes up a bug - the bug description is self explanatory.
6860401 FMA CPU Topology & Memory Topology needs to support Magny Cours(Multi chip Module)
6812502 Enable Generic-AMD FMA memory topology for Istanbul
These fixes enable CPU and memory diagnosis for the more recent AMD processor offerings. Beyond the typical changes of new model numbers, these processors have a more interesting topology with multiple processing nodes within a single package. Solaris 10 Update 9 understands these chips and creates the correct topology to support FMA diagnosis.
