A1-X1000: CPU frequency scaling and kernel 3.15

[xeno74]

Kernel 3.13 series: CPU frequency scaling

The kernel 3.13 series regulates the CPU frequency dynamically.

CPU frequency scaling enables the operating system to scale the CPU frequency up or down in order to save power. CPU frequencies can be scaled automatically depending on the system load, in response to ACPI events, or manually by userspace programs.

CPU frequency scaling is implemented in Linux kernel, the infrastructure is called cpufreq.

You can set the CPU frequency with the applet indicator-cpufreq for the panel.



New: Kernel 3.15

I have fantastic news for you!

Darren has created a new patch for the kernel 3.15 and he has compiled the kernel 3.15.6. It boots without any problems. Thanks Darren.

Firefox 31 and Thunderbird 31 are available for our A1-X1000.

Installation instructions for MATE's CPU Frequency Scaling Monitor

• Install the package mate-applets
  
  Code: [Select]
  apt-get install mate-applets
  
• To add CPU Frequency Scaling Monitor to a panel, right-click on the panel to open the panel popup menu, then choose Add to Panel ▸ CPU Frequency Scaling Monitor.
  

Sometimes, the automatic kernel CPU frequency regulator doesn't work exactly. For example SuperTuxKart. This game needs much CPU power but the kernel regulates the CPU frequency not to often to the highest rate. Thus the frame rate drops in STK.

By the way, Iceweasel 32.0 and Icedove 31.0 are available.
