A Live CD for XFreq

Monday February 17th, 2014By: CyrIng

XFreq is now supplied in a Live CD !

archlinux-xfreq.iso 510MB to download and burn to a CD or copy to any USB thumb key.

Restart the computer, choosing CD or USB key as the boot drive then select your locale, among English, French, German or Spanish.
You will go straight to an X Terminal.


Enter the following commands :

  1. install-xfreq.sh : to install XFreq from its tar file.
  2. xfreq : to run XFreq (use argument -D 1 for a MDI window)
  3. update-xfreq.sh : to download the last release which is automatically compiled for you !

Remark. NMI Watchdog is disabled because it interferes with XFreq when reading counters :

echo "0" > /proc/sys/kernel/nmi_watchdog
cat /proc/sys/kernel/nmi_watchdog

If you want to contribute to XFreq, this Live CD is ready for development :

  • Code::Blocks 13.12
  • The Data display Debugger 3.3.12
  • gdb 7.7
  • gcc 4.8.2
  • Linux kernel 3.13.5 (including its documentation)


The XFreq working directory layout is as follow :

src/XFreq/xfreq.c [source code]
src/XFreq/xfreq.h [header]
src/XFreq/Makefile [command line compilation]
src/XFreq/README [project history]
src/XFreq/XFreq.cbp [codeblocks file]
src/XFreq/bin/xfreq [the exec file]

Please let us know about the results of this Live CD and the execution of XFreq. In your comments we will appreciate the feature of your system (processor model, RAM timings, BIOS readings)
