Re: [Linux-ia64] Processor Rev.

[Gerrit.Huizenga@us.ibm.com]

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.
