cpupower-frequency-info(1)


NAME

   cpupower-frequency-info   -   Utility   to   retrieve   cpufreq  kernel
   information

SYNTAX

   cpupower [ -c cpulist ] frequency-info [options]

DESCRIPTION

   A small tool which prints out cpufreq information helpful to developers
   and interested users.

OPTIONS

   -e --debug
          Prints out debug information.

   -f --freq
          Get  frequency  the  CPU  currently  runs  at,  according to the
          cpufreq core.

   -w --hwfreq
          Get frequency the CPU currently runs  at,  by  reading  it  from
          hardware (only available to root).

   -l --hwlimits
          Determine the minimum and maximum CPU frequency allowed.

   -d --driver
          Determines the used cpufreq kernel driver.

   -p --policy
          Gets the currently used cpufreq policy.

   -g --governors
          Determines available cpufreq governors.

   -a --related-cpus
          Determines which CPUs run at the same hardware frequency.

   -a --affected-cpus
          Determines  which  CPUs need to have their frequency coordinated
          by software.

   -s --stats
          Shows cpufreq statistics if available.

   -y --latency
          Determines the maximum latency on CPU frequency changes.

   -o --proc
          Prints  out  information  like  provided  by  the  /proc/cpufreq
          interface in 2.4. and early 2.6. kernels.

   -m --human
          human-readable output for the -f, -w, -s and -y parameters.

   -n --no-rounding
          Output frequencies and latencies without rounding off values.

   REMARKS

   By  default  only  values  of  core  zero are displayed. How to display
   settings of other cores is described in the cpupower(1) manpage in  the
   --cpu option section.

   You can't specify more than one of the output specific options -o -e -a
   -g -p -d -l -w -f -y.

   You also can't specify the -o option combined with the -c option.

Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.



Free Software


Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.

Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.



Free Books


The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.

Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.



Education


Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.

Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
