This enables the deprecated /proc/acpi/processor/../performance

cross-architecture cpufreq interfaces should be used.

help

This adds the clock modulation driver for Intel Pentium 4 / XEON
|
||
|
|
processors. When enabled it will lower CPU temperature by skipping
|
||
|
|
clocks.
|
||
|
|
|
||
|
|
This driver should be only used in exceptional
|
||
|
|
circumstances when very low power is needed because it causes severe
|
||
|
|
slowdowns and noticeable latencies. Normally Speedstep should be used
|
||
|
|
instead.
