Linux 3.12 新特性带来双显卡方面的改进

[flwwater]

- The Radeon open-source kernel graphics driver has improved Dynamic Power Management, but it won't be until Linux 3.13 where Radeon DPM is enabled by default along with HDMI audio.

持续改进amd显卡的动态电源管理,我的3.11内核用起来很爽,不知改进了啥,但是到ubuntu14.04时候,动态电源管理自动启动,不用再像3.11一样手动开启了.另外,到ubuntu 14.04,amd显卡的HDMI音频输出也终于默认开启了.另外游戏性能较3.11版有提升.

- A brand new DRM/KMS driver in the form of the Snapdragon MSM driver written by Rob Clark to go along with his reverse-engineered Freedreno driver for Qualcomm Snapdragon/Adreno graphics.
支持高通Snapdragon/Adreno 芯片 .

- Run-time GPU power management so NVIDIA Optimus systems can dynamically power on/off the secondary GPU.
运行时的GPU电源管理,NVIDIA Optimus能够动态的打开或关闭第二个显卡核心.

- Experimental DRM render nodes support done by David Herrmann over the summer.

- AMD Berlin APU support as the first APU built upon AMD's Heterogeneous System Architecture (HSA).
AMD 新APU支持,内存统一寻址.

- The EXT4 file-system now supports aggressive extent caching and better recovery capabilities.
ext4文件系统更新

- Random F2FS, XFS, and Btrfs file-system improvements. This kernel does deliver on disk improvements.
F2FS, XFS, and Btrfs 文件系统更新

- zRAM has been promoted out of the staging area of the kernel. ZRAM supports a compressed block device in RAM to avoid paging to disk and is mostly of benefit for systems with limited amounts of system memory.
带来ZRAM带来内存压缩支持

- Various staging driver updates and sound driver work and other glorious work.
更多的音频驱动改进,支持22声道 .

Stay tuned for more Linux 3.12 coverage and continued benchmarks while soon our focus will be all about Linux 3.13 with its Intel Broadwell support.
