In addition to /proc/cpuinfo, there's a bunch of interesting stuff in /proc/palinfo/*, for instance:

[gerrit@elm3a86 palinfo]$ cat /proc/palinfo/version_info
PAL_vendor : 0xff (min=0xff)
PAL_A revision : 0x9 (min=0x9)
PAL_A model : 0x22 (min=0x22)
PAL_B mode : 0x9 (min=0x0)
PAL_B revision : 0x22 (min=0x0)

There is other stuff of interest in /proc/palinfo.

Chris pointed out that the minor numbers of the version aren't included here.

Also, reading one of the files here caused a panic with the B1 CPU steppings.

What is a good way to check the processor revision on the lion machines. I see people on the list refering to A1 or A2 stepping machines, but /proc/cpuinfo on our machines only shows this:

processor : 3
vendor : GenuineIntel
family : IA-64
model : Itanium
revision : 0
archrev : 0

plus the serial numbers and MHz and such. Does this just mean we have old CPUs, or is there a different way to check?

John-

The only way to find the revision that I know of is to check the paper work that came with your machine, that should list it. There's no instruction that will give that information at this point in time.

Hi,

In the latest kernel patch the output is slightly different. Here the minor number is .9. So 0x22 0x9 is read 2.2.9 for PAL version.

Yes, I am aware of this problem. I noticed yesterday while trying it out on our B1. I don't recall exactly which entry it is. I will be checking for that.

All,

I am using 2.4.0test4 with the trillian patch...

I noticed that 2.4.0test6pre9 is on www.kernel.org

Is the trillian patch merged on this kernel?

I don't know what the "trillian patch" is (;-), but if you're talking about the IA-64 patches I'm putting out: I'm not following the pre-patches in general. There are far too many for me too keep up (yes, I do like to get some work done occasionally, not just spend all my time merging other people's patches...).

I am plannnig to update the IA-64 diff at the end of this week (either test5 or test6, if it's out by then).

It happened here on 2 entries: perfmon_info and power_info.

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.
