FMA Demo Kit - UltraSPARC-T1/T2 Memory Support

Several months ago, shortly after the FMA Demo Kit was released, I added CPU support for UltraSPARC-T1 and -T2. At long last, memory support for systems based on these processors has arrived. Yes...I know this took a long time. The changes have been done for quite a while, but I was hung up in getting PSARC/2006/704 amended so I could use a private interface I needed to obtain DIMM serial numbers.

Anyway, here's what I posted to fm-discuss@opensolaris.org:

Hello, I'm pleased to announce that the Solaris FMA Demo Kit has been updated to include Memory demo support for the UltraSPARC-T1 and UltraSPARC-T2 processors. Note that Solaris Nevada build_58 or later is required for the T1/T2 demos. Solaris 10 uses require patch 125369-05 or better for CPU demos. Memory demos require Solaris 10 Update 4. These requirements are also in the README. For more information on the demo kit, including download, installation and usage instructions, please see: http://www.opensolaris.org/os/community/fm/demokit/ Thanks, -scott -http://blogs.sun.com/sdaven

Also, here's an example of the output for the various monitoring windows from a run on a T5220 system.

Console:
