Linux 4.6

Linux 4.6 kernel is out.
Now we finally have mainline support for a number of new ARM SoCs and platforms/boards.
There are various Radeon and AMDGPU improvements to make the open-source AMD graphics driver stack more stable and robust.
Initial NVIDIA GeForce GTX 900 “Maxwell” open-source support. While Pascal is days away from shipping, with Linux 4.6 there is finally 3D/acceleration support for Maxwell when grabbing NVIDIA’s signed firmware blobs they’ve made available. Before getting too excited, the support isn’t as mature as Kepler and they don’t yet have any re-clocking support for being able to provide good performance.
Runtime AHCI power management for greater power savings has been added to this release.
There’s also Dell and Alienware laptop support improvements, including for the popular Dell XPS 13 Skylake laptop.
Many sources of information will probably point out that this kernel release has new and better security features. Not everyone will take this piece of news for granted.
This is the “press release” of these new features with an interview of Greg Kroah-Hartman.
And this is a post from Brad Spengler, the creator and maintainer of GrSecurity in response of that PR.
I’ll let you make up your own mind on this topic.
Top features of 4.6:
– USB 3.1 SuperSpeedPlus (10 Gbps) support
– Improve the reliability of the Out Of Memory task killer
– Support for Intel memory protection keys
