For details, take a look at <file:Documentation/cpu-freq/>. If in doubt, say N.config X86_POWERNOW_K8_ACPI bool depends on X86_POWERNOW_K8 && ACPI_PROCESSOR depends on !(X86_POWERNOW_K8 = y && ACPI_PROCESSOR = m) default yconfig X86_SPEEDSTEP_CENTRINO tristate "Intel Enhanced SpeedStep" select CPU_FREQ_TABLE depends on ACPI_PROCESSOR help This adds the CPUFreq driver for Enhanced SpeedStep enabled mobile CPUs. This means Intel Pentium M (Centrino) CPUs or 64bit enabled Intel Xeons. For details, take a look at <file:Documentation/cpu-freq/>. If in doubt, say N.config X86_SPEEDSTEP_CENTRINO_ACPI bool depends on X86_SPEEDSTEP_CENTRINO default yconfig X86_ACPI_CPUFREQ tristate "ACPI Processor P-States driver" depends on ACPI_PROCESSOR help This driver adds a CPUFreq driver which utilizes the ACPI Processor Performance States. For details, take a look at <file:Documentation/cpu-freq/>. If in doubt, say N.comment "shared options"config X86_ACPI_CPUFREQ_PROC_INTF bool "/proc/acpi/processor/../performance interface (deprecated)" depends on PROC_FS depends on X86_ACPI_CPUFREQ || X86_SPEEDSTEP_CENTRINO_ACPI || X86_POWERNOW_K8_ACPI help This enables the deprecated /proc/acpi/processor/../performance interface. While it is helpful for debugging, the generic, cross-architecture cpufreq interfaces should be used. If in doubt, say N.config X86_P4_CLOCKMOD tristate "Intel Pentium 4 clock modulation" depends on EMBEDDED help This adds the clock modulation driver for Intel Pentium 4 / XEON processors. When enabled it will lower CPU temperature by skipping clocks. This driver should be only used in exceptional circumstances when very low power is needed because it causes severe slowdowns and noticeable latencies. Normally Speedstep should be used instead. For details, take a look at <file:Documentation/cpu-freq/>. Unless you are absolutely sure say N.config X86_SPEEDSTEP_LIB tristate default X86_P4_CLOCKMODendifendmenu
