Which processor to choose?

Hya,

Big apology for posting such a beginner question.

QUESTION: Which processor to choose when configuring kernel?

With my penguin, lshw says

Code:

*-cpu
          description: CPU
          product: Intel(R) Celeron(R) M CPU        410  @ 1.46GHz
          vendor: Intel Corp.
          physical id: 4
          bus info: cpu@0
          version: 6.14.8
          serial: 0000-06E8-0000-0000-0000-0000
          slot: U1
          size: 1460MHz
          width: 32 bits

 sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss tm pbe constant
_tsc up pni monitor tm2 xtpr

cpuid says

Code:

Vendor ID: "GenuineIntel"; CPUID level 10

Intel-specific functions:
Version 000006e8:
Type 0 - Original OEM
Family 6 - Pentium Pro
Model 14 - 
Stepping 8
Reserved 0

Extended brand string: "Intel(R) Celeron(R) M CPU        410  @ 1.46GHz"
CLFLUSH instruction cache line size: 8

I am using P4/Celelon(P4..)/ P4-M/Xeon and do not see major problem, but CPU freq scaling is not working, and while troubleshooting I am totally lost. (web search gives me too many, kernel documentation is not quite helpful, wikipedia is not either.) I also do not know which driver to use with cpu freq scaling...

Any suggestion will be appreciated!

Happy Penguins!

Have you compiled CPU scaling into your kernel? I don't think it is installed by default - this is for Slackware isn't it?

Hya,

Thanks for your reply. Yes, I am trying to compile in these features, and got lost. This penguin is Debian etch.

Happy Penguins!

Hya,

I finally solved problem (CPU freq is working), although I still am not confident if I am using right CPU (kernel parameter).

With this penguin, CPU freq works with kernel 2.6.20.11, but not 2.6.18 or less. I have not tried 2.6.19s. Govoner is P4-clockmod, the others don't work.

Happy Penguins!

The correct CPU is pentium-m.

Here is the absolute reference for cpu types: http://gentoo-wiki.com/Safe_Cflags#P...29.2FCeleron_M
