With the final release of the Linux 3.3 kernel
expected to happen in in a matter of days
, here's a recap of some of the most prominent Linux 3.3 kernel features that were introduced this cycle.
- The ASPM power regression has been properly addressed
in the mainline Linux 3.3 kernel, which was subsequently back-ported to the various stable series. There's also better ACPI / power management
with this soon-to-be-christened kernel.
- Radeon HD 5000 "Evergreen" series HDMI audio support
, which came via reverse-engineering
- The DMA-BUF Linaro buffer sharing mechanism
has landed, albeit in the Linux 3.3 kernel there really aren't any major drivers taking advantage of this infrastructure yet. DMA-BUF will be important going forward.
- Ethernet teaming support to combine several physical Ethernet ports into a virtual port.
- Xen performance fixes
- Many open-source graphics driver improvements
, including Semaphores support in the Radeon driver, better Intel Ivy Bridge support, and Samsung Exynos driver improvements. Nouveau, the reverse-engineered open-source NVIDIA driver, also saw many improvements.
- Byte Queue Limits
(BQL) is now in place for fighting buffer-bloat.
- Lots of staging area changes
- Online resize support
for EXT4 file-systems.
- Intel's NVM Express driver
has been introduced.
- Large Physical Address Extension (LPAE) support for 32-bit ARMv7 devices with more than 4GB of RAM.
Plus many more changes. Within the forums you can share your most anticipated Linux features.
