RC6 Disabled Again

RC6, the power-saving feature that should be one of the promising feature in the next Linux Kernel has (again) been switched off by default (you can turn it manually though) after the developer find it quite unstable on his machine and saying that it's not ready for prime time. RC6 is capable of saving power for mobile (and desktop) systems by allowing the integrated graphics processor to rest in a lower power-state, while at the same time is capable of boosting OpenGL performance (Taken from Phoronix).

The commit by Keith Packard has been approved by Linus and merged into Linux Kernel 3.2. If you prefer to enable this feature on your machine, pass i915.i916_enable_rc6=1 as a kernel command-line parameter.
