Clock scaling allows you to change the clock speed of the running CPU on the fly. This is a nice method to save battery power, because the lower the clock speed, the less power the CPU consumes. CPUFreq is a generic framework to make architecture implementation specifics transparent to a user. Currently, CPUFreq supports various ARM CPUs (Integrator, SA1100, SA1110), various x86's (AMD PowerNOW, VIA Cyrix Longhaul), and various SuperH CPUs (SH-4 7750/7751, SH-3, and so forth). This project also incorporates some work at reverse engineering support for Intel Speedstep technology.
