The big feature is Radeon dynamic power management support has finally come to AMD&#8217;s open-source driver along with early support for the Radeon HD 8000 &#8220;Sea Islands&#8221; GPUs. Phoronix tests have shown Radeon DPM is successful at improving power use and lowering temperatures while delivering great performance.<\/li>\n<li>There&#8217;s a new DRM display driver for the Renesas R-Car SoC. <\/li>\n<li>Intel Haswell improvements and Valley View \/ Bay Trail support is now ready for Linux desktop usage.<\/li>\n<li>H.264 \/ MPEG-2 video decoding for Nouveau with select NVIDIA GPUs bearing the VP2 engine as part of the PureVideo HD support. This is exposed in Gallium3D via the VDPAU state tracker. There&#8217;s also early GK110 GPU support. The NVIDIA GK110 is the firm&#8217;s latest high-end Kepler GPU.<\/li>\n<\/ul>\n<p>Disk \/ File-System: <\/p>\n<ul>\n<li>LZ4 compression support. <\/li>\n<li>Zswap was merged for compressed swap caching.<\/li>\n<li>Various XFS file-system improvements.<\/li>\n<li>Performance tuning for Btrfs. <\/li>\n<li>F2FS file-system updates. <\/li>\n<li>EXT4 file-system updates.<\/li>\n<li>The Lustre file-system client was merged for the first time.<\/li>\n<\/ul>\n<p>CPU: <\/p>\n<ul>\n<li>AVX2 Crypto optimizations. <\/li>\n<li>PowerPC improvements from IBM. <\/li>\n<li>Continued ARM improvements. <\/li>\n<li>Xen and KVM virtualization now work for 64-bit ARM.<\/li>\n<\/ul>\n<p>General Hardware &#038; Miscellaneous Improvements: <\/p>\n<ul>\n<li>Input device improvements. <\/li>\n<li>Lots of audio \/ sound improvements. <\/li>\n<li>With Linux 3.11, Wine can now handle Windows RT applications. <\/li>\n<\/ul>\n<h3>Download &#038; Install Linux Kernel 3.11:<\/h3>\n<p>The Kernel PPA has updated DEB packages for Ubuntu and its derivatives.
