Among the material on the table for Linux 4.16 includes:
- More optimizations/improvements around Meltdown/Spectre mitigations, including Variant One mitigations and KPTI/Retpoline tuning/optimizations as well as ARM64 KPTI support. Some of this may be back-ported to earlier kernels.
- Many DRM driver improvements from more AMDGPU DC action to Intel Cannonlake improvements and more happenings for the smaller Direct Rendering Manager drivers.
- SoundWire is finally arriving to Linux 4.16 as a new subsystem.
- The long-awaited mainlining of the VirtualBox Guest Driver as part of getting more of the VBox kernel code upstream.
- AMD Secure Encrypted Virtualization for KVM/Linux in 4.16 for EPYC and Ryzen Pro users.
- Jailhouse guest support for this hypervisor developed the past few years by Siemens.
- BPF error injection support.
- Skylake X P-State support.
- Some new sound drivers, most notably for some Allwinner SoC users.
- Input and HID updates including more Year 2038 fixes.
- LightNVM 2.0 support appears to be in place.
- Btrfs RAID improvements.
- ARMv8.4 additions.
- More BFQ optimizations for delivering better performance out of this I/O scheduler.
Stay tuned for more Linux 4.16 feature talk when the merge window opens and we get a better idea of all the changes in place for this next kernel release. Of course, as Linux 4.16 settles down there will be plenty of benchmarks on Phoronix.
