Can't find any docs on this. I just upgraded to a vanilla 2.4.21 kernel, and want to add cpufreq support back for my Intel P4, in my Thinkpad A31p. I had this working with 2.4.20, using the 'advanced' patch from http://www.brodo.de/cpufreq/, and controlling it by echo-ing stuff to /proc/cpufreq I couldn't make any of the patches on www.brodo.de/cpufreq_old apply to my kernel cleanly. They look rather old, and the page is no longer in use. So I donloaded the latest patch from ftp://ftp.linux.org.uk/pub/linux/cpufreq/ (ftp://ftp.linux.org.uk/pub/linux/cpufreq/cpufreq-LINUX_2_4-20030617.tar.bz2) and applied this. Now, it says that my cpu is unsupported. As follows: shiro proc # dmesg | grep cpufreq cpufreq: Intel(R) SpeedStep(TM) support $Revision: 1.7.2.6 $ cpufreq: Intel(R) SpeedStep(TM) for this processor not (yet) available. /proc/cpufreq no longer exists. Seems strange. It *used* to work with the old patch, but somehow has decided not to work with the new one. Am I missing some kernel parameter or something? Or has support been taken out? Or am I using the wrong patch? Thanks Simon output of /proc/cpuinfo follows: shiro linux # cat /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 : 1199.045 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 bogomips : 2385.51
