Red Hat keeps graphics chips chilled
Historically, most power management work in Linux has been focused on the CPU -- keeping it cool, making sure it switches to a slower speed when idle, and so on. But as graphics chips continue to improve, they're starting to munch through battery life too. Our hardware-loving chums at Phoronix have looked at the latest work from Red Hat to conserve power on GPUs, which focuses on 'clock-gating' and frame-buffer compression techniques. As always, though, much of the work depends on access to spec-sheets from the hardware vendors.
