Sorry... I posted this to the cpufreq list yesterday but I didn't get a response. Apologies for crossposting.
I've just upgraded to 2.6.0-test10 and am trying to use the new cpufreq stuff in there. I had everything working perfectly with 2.4.21-ac2, and the old /proc/cpufreq interface.
I have a P4 2ghz (in a thinkpad), but it's not running at over about 1.2ghz now. If I `cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq` it tells me: "1198976". It should go faster than that. Similarly, scaling_available_frequencies says "149872 299744 449616 599488 749360 899232 1049104 1198976"
Enabling the old interface in the kernel and doing a `echo -n 0%0%100%performance > /proc/cpufreq` doesn't change things either.
Here is my /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Mobile Intel(R) Pentium(R) 4 - M CPU 2.00GHz stepping : 7 cpu MHz : 1198.976 cache size : 512 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 pae mce cx8 sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid bogomips : 2359.29
Any ideas?
Cheers, Simon
