Re: [Linux-ia64] Processor Rev.

[Tim Riker <TimR@CalderaSystems.com>]

There is some documentation on serial #s (the stickers not the
electronic IDs) in the Intel literature. In my "Intel Workstation SDV,
A1 Stepping Processor Replacement" manual there is a section on page 20
entitled "Identification of Upgrade Processor Stepping" with a table
mapping the 4 digit postfix to the A2 and A3 stepping. This also
includes some comments about the state of software revision detection.

I do not know if this info is truly public, so I have not copied this
info here. Perhaps someone from Intel would like to comment?

These postfixes are of the format Q[letter][number][number]. I would
assume there is a complete table available someplace that would include
A1-A3 and B0-B1 stepping maps, but I have not seen it.

The only reliable option I know of is to open a QuAD ticket on the
system and ask Intel.
