While we are just a few days into the Linux 3.8 kernel
merge window and there's still a number of pull requests that have yet to appear for this next kernel development cycle with new features, there's already a ton of exciting work. If you missed the horde of Phoronix articles in the past few days covering the prominent features, here's a recap showing why this Linux kernel being developed over the holidays is a great gift for its users.
Among the features for the Linux 3.8 kernel that have been merged thus far include:
- Work towards true CPU hot-plug support
- Improved ACPI power management
in the never-ending battle of improving the Linux power efficiency and performance-per-Watt.
- A wide variety of XFS file-system changes
- Continued work on 64-bit ARMv8 / AArch64 support
- Tons of staging driver changes
- Support has been dropped for the old i386 CPUs
to reduce the complexity of the Linux kernel.
- DMA-BUF support in V4L2
so that Video 4 Linux 2 drivers may share buffers with their DRM graphics drivers in a zero-copy manner.
- In certain workloads, the Linux kernel now goes through a lot less system memory
- Linux support for the Microsoft Windows 8 multi-touch protocol
- Audio driver improvements
, including new sound card drivers.
- Performance improvements for cryptography
- Support for the yet-to-be-released IBM POWER8 CPUs
- While the DRM pull request hasn't yet been submitted, there are Radeon performance improvements
, various other Radeon changes
, Exynos driver improvements
, Intel/Nouveau changes, and much more.
Stay tuned for more of the Linux 3.8 pull requests that have yet to surface but will in the coming week.
