---|
3 | # This configuration file controls the behavior of both the |
---|
4 | # cpuspeed daemon and various cpufreq modules. |
---|
5 | # For the vast majority of users, there shouldn't be any need to |
---|
6 | # alter the contents of this file at all. By and large, frequency |
---|
7 | # scaling should Just Work(tm) with the defaults. |

9 | ### DRIVER ### |
---|
10 | # Your CPUFreq driver module |
---|
11 | # Note that many drivers are now built-in, rather than built as modules, |
---|
12 | # so its usually best not to specify one. The most commonly-needed driver |
---|
13 | # module these days is 'p4-clockmod', however, in most cases, it is not |
---|
14 | # recommended for use. See: http://lkml.org/lkml/2006/2/25/84 |
---|
15 | # default value: empty (try to auto-detect/use built-in) |
---|
16 | DRIVER= |
---|
17 | |
---|
18 | ### GOVERNOR ### |
---|
19 | # Which scaling governor to use |
---|
20 | # Details on scaling governors for your cpu(s) can be found in |
---|
21 | # cpu-freq/governors.txt, part of the kernel-doc package |
---|
22 | # NOTES: |
---|
23 | # - The GOVERNOR parameter is only valid on centrino, powernow-k8 (amd64) |
---|
24 | # and p4-clockmod platforms, other platforms that support frequency |
---|
25 | # scaling always use the 'userspace' governor. |
---|
26 | # - Using the 'userspace' governor will trigger the cpuspeed daemon to run, |
---|
27 | # which provides said user-space frequency scaling. |
---|
28 | # default value: empty (defaults to ondemand on centrino, powernow-k8, |
---|
29 | # and acpi-cpufreq systems, userspace on others) |
---|
30 | GOVERNOR= |
---|
31 | |
---|
32 | ### FREQUENCIES ### |
---|
33 | # NOTE: valid max/min frequencies for your cpu(s) can be found in |
---|
34 | # /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_frequencies |
---|
35 | # on systems that support frequency scaling (though only after the |
---|
36 | # appropriate drivers have been loaded via the cpuspeed initscript). |
---|
37 | # maximum speed to scale up to |
---|
38 | # default value: empty (use cpu reported maximum) |
---|
39 | MAX_SPEED= |
---|
40 | # minimum speed to scale down to |
---|
41 | # default value: empty (use cpu reported minimum) |
---|
42 | MIN_SPEED= |
---|
43 | |
---|
44 | ### SCALING THRESHOLDS ### |
---|
45 | # Busy percentage threshold over which to scale up to max frequency |
---|
46 | # default value: empty (use governor default) |
---|
47 | UP_THRESHOLD=60 |
---|
48 | # Busy percentage threshold under which to scale frequency down |
---|
49 | # default value: empty (use governor default) |
---|
50 | DOWN_THRESHOLD=40 |
---|
51 | |
---|
52 | ### NICE PROCESS HANDLING ### |
---|
53 | # Let background (nice) processes speed up the cpu |
---|
54 | # default value: 0 (background process usage can speed up cpu) |
---|
55 | # alternate value: 1 (background processes will be ignored) |
---|
56 | IGNORE_NICE=0 |
