ACPI, Linux and Dynamic CPU frequency ?
« on: March 06, 2014, 09:31:42 PM »
Hi,

I have a basic question:

I'm using Linux (Ubuntu) and CPU I7.

The current CPU frequency is 1200hz, the maximum CPU frequency is 2100hz.

My Q is as follows:

Does Linux (or the INTEL CPU's)  increase the CPU frequency when the system is loaded ?

(i.e when the total CPU's are 70% loaded (for example) , Does the OS (without the user interference) may increase the CPU freq from 1200 to the max freq 2100, in order to decrease the load on the CPU's ?) (and without the user interference) ?

Thank's
