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.
