CONFIG_CPU_FREQ
Clock scaling allows you to change the clock speed of CPUs on the
fly. This is a nice method to save battery power on notebooks,
because the lower the clock speed, the less power the CPU consumes.
For more information, take a look at linux/Documentation/cpufreq or
at <http://www.brodo.de/cpufreq/>
If in doubt, say N.
CONFIG_X86_POWERNOW_K6
This adds the CPUFreq driver for mobile AMD K6-2+ and mobile
AMD K6-3+ processors.
For details, take a look at linux/Documentation/cpufreq.
If in doubt, say N.
CONFIG_X86_P4_CLOCKMOD
This adds the CPUFreq driver for Intel Pentium 4 / XEON
processors.
For details, take a look at linux/Documentation/cpufreq.
If in doubt, say N.
CONFIG_ELAN_CPUFREQ
This adds the CPUFreq driver for AMD Elan SC400 and SC410
processors.
You need to specify the processor maximum speed as boot
parameter: elanfreq=maxspeed (in kHz) or as module
parameter "max_freq".
For details, take a look at linux/Documentation/cpufreq.
If in doubt, say N.
CONFIG_X86_LONGHAUL

processors.
For details, take a look at linux/Documentation/cpufreq.
If in doubt, say N.
