And, thus, we decend into more /proc crappyness.
After *lots* of discussion and months of waiting, it was decided between Alan, David Jones, Jeff Garzik, and other affected parties that /proc/sys/cpu/#/whatever would be a reasonable. It has even appeared on lkml a couple of times in the past.
Currently, there is an allocated sysctl number in include/linux/sysctl.h for /proc/sys/cpu, and it is used by the cpufreq code to provide:
/proc/sys/cpu/#/speed /proc/sys/cpu/#/speed-max /proc/sys/cpu/#/speed-min
However, it's true that some of that needs to be pulled out so anything can use /proc/sys/cpu/#. Just takes the necessary parties to get together to do the hard work, and with the right hardware to test it out.
