Recently Linux Kernel 3.11 has been released & just few days after release few changes have queued up that will be included in upcoming Linux kernel 3.12

Features :
- GPU Run-time Power Management : It helps to switch ON and OFF the secondary GPU as per it's usage (Very useful for nVidia Optimus)

- zRAM : It's been promoted in main area of Kernel from 3.12 onwards.

- AMD 'Berlin" HSA APU Support

- Snapdragon DRM/KMS Driver : Work by Rob Clark as Freedreno project who have reversed engineer Opensource 2D/3D support for Qualcomm's ARM SoC.

Seems like most of the upcoming changes are related to graphics tweaks/changes & hardware support.

    Update :
    --> There is EXT4 File-System update incoming in 3.12 which includes two main features :

    • Aggressive Extent Caching : It is very good feature which will lead to usage of lesser memory than current stats & asynchronous I/O improvements.

    --> Also, existing sound drivers are improved & there's new sound hardware drivers included.

    • HDMI & DisplayPort audio updates.

    Update :
    Samsung's F2FS (Flash Friendly File System) has gained major performance improvement & bug fixes for upcoming Linux Kernel 3.12

    ----------------------------------------------------------------------------
    On side note : You should use F2FS for RPi or any ARM based mini-computer like Beaglebone,UDOO,etc. It not only increases the life of SDHC but it's also faster than Ext4.
