Package: linux-2.6 Version: 3.1.8-2 Severity: normal Dear Debian folks,
this is the same report as report #490108 [1] which has been closed already. I am submitting a new report instead of reopening #490108, since this request only involves amd64 which was not fixed. $ grep -i clockm /boot/config-3.1.0-1-* /boot/config-3.1.0-1-686-pae:CONFIG_X86_P4_CLOCKMOD=m /boot/config-3.1.0-1-amd64:# CONFIG_X86_P4_CLOCKMOD is not set Frequency scaling does not work with the following Intel Pentium 4 processor when using the Linux kernel for amd64. $ more /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Pentium(R) 4 CPU 3.00GHz stepping : 9 cpu MHz : 2999.275 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx lm constant_tsc pebs bts nopl pni dtes64 monitor ds_cpl cid cx16 xtpr lahf_lm bogomips : 5998.55 clflush size : 64 cache_alignment : 128 address sizes : 36 bits physical, 48 bits virtual power management: processor : 1 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Pentium(R) 4 CPU 3.00GHz stepping : 9 cpu MHz : 2999.275 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 apicid : 1 initial apicid : 1 fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx lm constant_tsc pebs bts nopl pni dtes64 monitor ds_cpl cid cx16 xtpr lahf_lm bogomips : 5999.73 clflush size : 64 cache_alignment : 128 address sizes : 36 bits physical, 48 bits virtual power management: The reason is, that this processor does not have speedstep technology and therefore neither acpi-cpufreq nor speedstep-centrino modules can be used for frequency scaling. To get something similar module p4_clockmod provides frequency throttling [1], but is currently not included in the package for amd64. It would be great if you could build that module and distribute it in the package for amd64.
