Linux 3.12 Radeon DPM System Monitor CPU Governors Intel Core i7-4770K testing of Radeon HD 6950 graphics card on Linux 3.11 and 3.12 kernels looking at CPU usage and CPU frequency using MONITOR environment variable with Phoronix Test Suite. Benchmarking by Michael Larabel for a future article on Phoronix.com. Now with CPUfreq performance governor on Linux 3.12 too.
