There are different versions of CPUClock, which have different purposes, or are for specific types of hardware.
- Configure tool version
- This is a Boot-Configuration tool version. Once installed it will
appear in Boot-Configuration (double click !Boot in the root
directory). It allows the fast (and slow) cpu speed to be set, and the
setting will be retained over a reboot or reset. This version does not
give a continuous display of cpu speed, but is intended only to set
the cpu speed - useful in hot weather to keep the cpu temperature
down.
This version should run on OMAP3, OMAP4, iMX6, and IGEPv5 hardware.
- Standard version
- This version installs on the iconbar. It allows the fast (and
slow) cpu speed to be set, and also gives a readout of the 'current'
CPU speed (updated by default every second) as the OS switches between
'Fast' and 'Slow', depending on the processor loading.
This version should run on OMAP3, OMAP4, iMX6, and IGEPv5 hardware.
- Automatic CPU temperature control via CPUTmpMon
- This version installs on the iconbar, and has the same facilities
as the standard version (see above). In addition it integrates with
CPUTmpMon (which reads the CPU die temperature) to allow the CPU speed
to be moderated automatically if the CPU temperature rises above a
preset level (user choice). Different versions of CPUTmpMon, which are
required for different hardware, are supplied within CPUClock, and the
correct version should be run by CPUClock.
This version should run on OMAP3, OMAP4, iMX6, and IGEPv5 hardware.
