248config X86_ACPI_CPUFREQ_PROC_INTF
249 bool "/proc/acpi/processor/../performance interface (deprecated)"
250 depends on PROC_FS
251 depends on X86_ACPI_CPUFREQ || X86_POWERNOW_K7_ACPI || X86_POWERNOW_K8_ACPI
252 help
253 This enables the deprecated /proc/acpi/processor/../performance
254 interface. While it is helpful for debugging, the generic,
255 cross-architecture cpufreq interfaces should be used.
256
257 If in doubt, say N.
