 |
|
I bought this cute little 11.5" gateway netbook, the lt3103u, and have been banging my head trying to get CPU frequency scaling working.
It has a processor that is identifies as:
| Code: |
archaeopteryx daddio # cat /proc/cpuinfo
processor : 0
vendor_id : AuthenticAMD
cpu family : 15
model : 124
model name : AMD Athlon(tm) Processor L110
stepping : 2
cpu MHz : 1197.038
cache size : 512 KB
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow up rep_good extd_apicid pni cx16 lahf_lm svm extapic cr8_legacy 3dnowprefetch
bogomips : 2394.07
TLB size : 1024 4K pages
clflush size : 64
cache_alignment : 64
address sizes : 40 bits physical, 48 bits virtual
power management: ts fid vid ttp tm stc 100mhzstep

I can't figure out what is wrong. Everything else is working. I have suspend-to-ram, acpi, even the thermal sensor.
But, though I have tried enabling powernow-k8 as a module, as a builtin, and even tried enabling the acpi p-states driver it will not work.
I just get this:
| Code: |
archaeopteryx daddio # modprobe powernow-k8
FATAL: Error inserting powernow_k8 (/lib/modules/2.6.33-gentoo/kernel/arch/x86/kernel/cpu/cpufreq/powernow-k8.ko): No such device
|
I have read that the identifier is a little weird for this cpu, everyone says its a sempron, but AMD won't say, and gateway just calls it an Athlon64.
help? |

Hai,
i had the same trouble with my amd64 as well. Then I played a bit with my kernel configuration and now it works when I compile my powernow-k8 as a module.
