Solaris 10 Update 8 FMA Fixes

Solaris 10 Update 8 is now posted and available for download. And there's been plenty of bug fix work for FMA. Beyond lots of memory leak and core dump fixes, here's my favorite fixes.


6743295 fault.memory.dimm is overloaded
6758561 KA pages for fault.memory.dimm\* are needlessly different

These two fixes provide some cleanup for DIMM faults. CR 6743295 explains the more tangible benefit, IMHO. In addition to getting the information a DIMM is declared faulty, there is now better separation via the fault and knowledge article explaining why the DIMM is deemed bad.


6394503 fmdump should show contents of rotated logs without specifying them explicitly
6535637 Add Severity level to payload of list.suspects event

I lump these together as administrative improvements. The first expanding fmdump to show information from historical logs and not just the current log. FMA error and fault logs are rotated periodically, and the new behavior is to display data from all logs.


6618751 Include memboard in T5440 FBR/FBU diagnosis

Beyond fixing a nasty core dump in the diagnosis flow, this fix also improves the diagnosis. This was a gap from when T5440 first shipped. On configurations where DIMMs on memory boards are in the mix, the memory board itself is part of the FB-DIMM channel. That component is now included in the diagnosis of channel errors.


6747341 Add FMA to hermon driver
6656720 Initial hxge driver

Add two more FMA hardened drivers to Solaris 10!


6800878 CMI_MAX_{CHIPS,CORES_PER_CHIP,STRANDS_PER_CORE} should be dynamic

The impetus for this change is the higher core counts coming in the x86 world. With newer chips from both AMD and Intel, the previously defined maximums would be insufficient to fault manage all the cores and strands. Not anymore :)


6818561 FMA topology fails on Sun Blade T6300

This was just a flat out embarrassment. Topology completely missing from the T6300 blades, rendering FMA largely ineffective (errors still logged, but diagnosis crippled). Glad this one is fixed.
