Info on Pentium Processor Family Kernel 2.6.29


There seem to be a number of new options which could apply to my processor and I've found conflicting reports on which I should be using in the 2.6.29 kernel options.

Am I MPENTIUMM or MPENTIUM4? (Also, is there a place where vendor_id, cpu family, and model are listed with their corresponding kernel processor family. Wouldn't it be cool if the kernel configurator had an option to automatically check cpuinfo and determine the best processor family?)

Here's my cpuinfo:
Code:
balder ~ $ cat /proc/cpuinfo
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 13
model name      : Intel(R) Pentium(R) M processor 1.60GHz
stepping        : 6
cpu MHz         : 600.000
cache size      : 2048 KB
fdiv_bug        : no
hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : 2
wp              : yes
flags           : fpu vme de pse tsc msr mce cx8 sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss tm pbe up bts est tm2
bogomips        : 1198.95

Try...

If you have the command "lshw" installed you can use it as root to gain more detailed information about your CPU. Both Intel and Wikipedia have information on Intel CPUs by name and FSB, cache size, etc. to confirm and crosscheck by specifications.

From what you have posted, I judge the CPU to be this one.

Dothan P/N 80536

Yes, but...

Thank you for your response.

I have been to the Wikipedia and other resources... however, the 2.6.29-r2 kernel has a myriad of new options for this range of processor.

MPENTIUMM or MPENTIUM4 are the most likely candidates for my processor but the built-in kernel description doesn't specify the difference between these in relation to cpu family and model.

The processor...

I thought that if you could identify this as a Pentium M725, if that is what it is, and check with Intel for more information and documentation, you would have what you needed to choose options in the kernel.

The kernel may not differentiate by family and model, but does it do so by any information you can find, particularly if you could find the full specifications from Intel?

Does the kernel request information where the request is not relevant for your particular processor, where the kernel would better treat this processor at a more general level, as one of a group of similar processors, but has a request for a level of detail relevant to the others, asking perhaps for information about options that apply for some but not all Pentium processor.

I treated this as a hardware inquiry, but you might ask to have it moved to Linux-Kernel in the Software forum.

Have you tried pursuing the matter in documentation for the kernel and the kernel development project?

We may be at cross purposes here; I have no experience with the kernel but I can read a specification.

Perhaps the moderators...

At the bottom of the Forum Hardware opening page are links to the moderators active at the time. You might use that link to write a note asking about switching your thread. Maybe it would get more traffic and thereby more responses in Newbie, although you need qualified insight more a quantity of replies.

Have you tried cpuid ?

http://etallen.com/cpuid.html


maybe the Features flags will hold a clue for functionality..

Look and you shall find.

My repository for openSUSE 11.0 is without cpuid but has x86info. Try both if you can.

You might give farslayer a thanks, just to encourage his good work.

Thumbs up Thank you to everyone

I'm going through all the information given and I REALLY appreciate everyone's input.

When I find the solution I will be sure to post back to the thread so others searching for similar information can benefit, and I will change the Thread title to add SOLVED.

Cheers,

Kirk

Thumbs up x86info has answered the question

My processor is still in the Pentium III range of its family, so I assume my config processor family should be MPENTIUMM not MPENTIUM4.

Thanks, especially to farslayer and thorkelljarl.

Cheers,

Kirk
