For Phoronix readers, as has already been covered extensively, the likely most exciting end-user feature is Radeon DPM support as finally implementing dynamic power management support for the open-source AMD driver means better performance, lower operating temperatures, and lower power usage. The benchmarks have been great.
Aside from Radeon DPM, other great 3.11 features include:
- Radeon HD 8000 Sea Islands support.
- Full Intel Bay Trail (Valley View) Linux graphics support.
- H.264 and MPEG-2 video decoding support for the Nouveau driver via the VP2 PureVideo engine.
- Zswap compressed swap caching was finally merged.
- Mainlined on the file-system side was the Lustre client.
- Wine support for Windows RT applications.
- Possible power consumption/performance improvements.
- Tons of other changes.
Expect Linux 3.11 final to be out within a couple weeks time barring any last-minute major regressions.
