 Posted: Sun Jun 05, 2005 1:29 pm Post subject: which kernel source for dothan speedstep support? |
 |
|
I've been reading several website about speedstep support for a dothan processor, but they were most of time about 2.6.8 kernels.
Can somebody tell me which kernel (vannila, gentoo-sources...) I have to use to get speedstepping properly working? Do I have to apply additional patches?
/proc/cpuinfo:
| Code: | processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 13
model name : Intel(R) Pentium(R) M processor 1.70GHz
stepping : 6
cpu MHz : 1698.711
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 est tm2
bogomips : 3399.63

I got a Banias Pentium -M Processor and I've got good experience with the vanilla-sources 2.6.11.10 Kernel.
Speedstepping works perfectly with powernowd and the speedstep-centrino kernel-module.
Also patching the kernel with the swsusp2- and the bootsplash-Patch works. |

From what I found on the internet, Banias processors are correctly supported, but can somebody help me to get my dothan working  . |

Does it also work when you are running on battery? I think the kernel sees my processor as a banias centrino. |

I have found these two patches: cpufreq-speedstep-dothan-3.patch and dothan-speedstep.patch.
I have applied these patches to my kernel (gentoo-sources 2.6.11-r9). Everything seems to be fine, but these patches are for older kernels. Are there somewhere patches like these for a 2.6.11.x kernel or is it safe to use these with my kernel? |

I use the ondemand governor from the kernel sources w/o sny addditional software like powernowd - and I am happy with the power management from the kernel itself. |

I just noticed that no ACPI event is generated when I go on battery  , so I can't tell you, but this should be a Toshiba BIOS problem.
To check the CPU model cat /proc/cpuinfo and take a look at the source code of speedstep-centrino: there are a couple of tables near the beginning mapping family, model and stepping to CPU type.
My CPU is a 755 (Dothan B1 at 2.0 GHz) and is 6,13,6. |
