Some of our highlights for the Linux 4.1 kernel include:
- Significant performance improvements for certain hardware as well as power consumption/efficiency improvements for select Intel hardware.
- Nouveau ships with GeForce GTX 750 acceleration support that doesn't require the manual extracting/setup of any non-redistributable firmware blobs.
- Intel XenGT vGPU support for those wanting Intel graphics acceleration support from Xen guests. The KVM support is still being developed.
- Radeon DisplayPort MST support.
- EXT4 file-system encryption thanks to work done by Google in looking to add file-system-level EXT4 encryption for Android.
- Better RAID 5/6 support with MD RAID.
- Improved laptop support from major vendors along with better Chromebook Pixel 2 support.
- Continued bring-up of Intel Skylake support within Linux. Skylake is still on course for launching later this year.
- ACPI support for AArch64 / 64-bit ARM.
- Many other changes.
Linux 4.1 has shaped up nicely and is performing well as with the many daily Git kernel benchmarks happening every morning at LinuxBenchmarking.com. Linux 4.1 is a great release but Linux 4.2 is next and new features are on the way.
