From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050512 Red Hat/1.0.4-1.4.1 Firefox/1.0.4 Description of problem: All the utilities included in kernel-utils except cpuspeed has a man page. Please take the output of cpuspeed -h and put it in man format so I can run "man cpuspeed". Version-Release number of selected component (if applicable): kernel-utils-2.4-13.1.66 How reproducible: Always Steps to Reproduce: 1. man cpuspeed Actual Results: No manual entry for cpuspeed Expected Results: cpuspeed -h cpuspeed v1.1b This program monitors the system's idle percentage and reduces or raises the CPU clock speed and voltage accordingly to minimize power consumption when idle and maximize performance when needed. This is the default behavior. The program can also be configured to reduce the CPU clock speed if the CPU temperature gets too high or if the computer's AC adapter is disconnected. Usage: cpuspeed [Options] Options: -d Tells the process to daemonize itself (run in background). -i <interval> Sets the interval between idle percentage tests and possible speed changes in 1/10 second increments (default is 20). -p <fast up> <threshold> Sets the CPU idle percentage thresholds. <fast up> is the idle percentage below which the CPU will be set to the highest possible speed. <threshold> is the idle percentage above which the CPU speed will be decreased and below which the CPU speed will be increased (defaults are 10 and 25). -t <temp file> <maxtemp> Sets the ACPI temperature file and the temperature at which CPU will be set to minimum speed. -a <AC file> Sets the ACPI AC adapter state file and tells the program to set the CPU to minimum speed when AC adapter is disconnected. To tell the program to stay at the highest CPU clock speed to maximize performance, send the process the SIGUSR1 signal. To tell the program to stay at the lowest CPU clock speed to maximize battery life, send the process the SIGUSR2 signal. To tell the program to go back to scaling the CPU clock speed dynamically, send the process the SIGHUP signal. Example: cpuspeed -d -i 10 -t /proc/acpi/thermal_zone/THRM/temperature 79 \ -a /proc/acpi/ac_adapter/ACAD/state This will have the program check (and possibly change) the CPU speed once every second and go to minimum CPU speed if the temperature goes above 79 or the AC adapter is disconnected.

The component of this request is planned to be updated in Red Hat enterprise Linux 4.5. This enhancement request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release.

Received this bug on 1st of Sep for LingNing. Should be easy for updating an errata for kernel-utils. Dave, since you are the maintainer of kernel-utils, is it a package that LingNing can update in RHEL4.5?
Comment 10 Jarod Wilson 2007-01-15 15:26:40 UTC
A cpuspeed manpage based on 'cpuspeed --help' output is now included as of kernel-utils-2.4-13.1.97.
