Thanks very much to everyone who responded to my email to freebsd-mobile (subject: "Looking for Pentium M owners...") with their processor data. At least in the 130nm version of the Pentium M (codename "Banias") the MSR (model specific register) I'm looking at does what I thought it did. However, I haven't heard from anyone with a 90nm (codename "Dothan") Pentium M, and these are the ones I really need to hear about -- I need to make sure Intel didn't change the MSR between the two versions of the Pentium M. The 90nm Pentium M was released in May, and will normally be advertised as a "Pentium M 7xx", where 7xx is 713, 715, 723, 725, 733, 735, 738, 745, or 755. I'm not sure what hw.model will be on these -- it might contain this model number, or it might simply be "Intel(R) Pentium(R) M processor xxxxMHz". If you have a Pentium M from the past three months, and you think it might be a 90nm (Dothan) processor, please do the following: 1. Download and extract http://www.daemonology.net/tmp/dumpmsr.tgz 2. `make` 3. `kldload ./dumpmsr.ko` 4. `kldunload dumpmsr` When you kldload, it should print three lines; please send me those, along with the output of `sysctl hw.model`, and (if you know) the model name/number under which Intel advertises your processor. If I can find anyone with a 90nm Pentium M, then I should be able to support them in the Enhanced SpeedStep code I'm writing; if not, I'll release code which only works on the older 130nm Pentium Ms. Colin PercivalReceived on Sun Aug 15 2004 - 16:19:11 UTC
