2003.2 Deprecated Interfaces
201-------------------------
202
203Depending on your kernel configuration, you might find the following
204cpufreq-related files:
205/proc/cpufreq
206/proc/sys/cpu/*/speed
207/proc/sys/cpu/*/speed-min
208/proc/sys/cpu/*/speed-max
209
210These are files for deprecated interfaces to cpufreq, which offer far
211less functionality. Because of this, these interfaces aren't described
212here.

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.
