Linux內(nèi)核3.12發(fā)布 帶來驅(qū)動更新
Linus Torvalds宣布3.12穩(wěn)定版內(nèi)核，帶來很多驅(qū)動更新和改進(jìn)，比如Radeon顯卡，AMD APU，高通梟龍/Adreno，NVIDIA Optimus，各種文件系統(tǒng)和其他驅(qū)動等更新。
Linus在郵件列表中說：“我本來在猶豫要不要來個RC8，不過下周要出去旅游，網(wǎng)絡(luò)不好，還是不延遲了”。并表示3.19后就會進(jìn)入4.0時代，不過那是一年后的事情了。
該版新特性：
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.
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.
Run-time GPU power management so NVIDIA Optimus systems can dynamically power on/off the secondary GPU.
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).
The EXT4 file-system now supports aggressive extent caching and better recovery capabilities.
Random F2FS, XFS, and Btrfs file-system improvements. This kernel does deliver on disk improvements.
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.
Various staging driver updates and sound driver work and other glorious work.
