PCI peer-to-peer memory being merged for benefiting use-cases from device-to-device memory copies from NICs directly to SSD storage or for multi-GPU deployments. Hopefully in 2019 we find 2.5G Ethernet becoming standard for new Intel hardware. Intel 2.5G Ethernet support was added via the new "IGC" driver. Faster FUSE performance for file-systems in user-space. New F2FS features, including a checkpoint mouint option for atomic updates of the entire file-system. Several Btrfs performance improvements. RAID10 improvements for MD RAID / Linux Software RAID. There is also now mainline ARM SBC support for the Orange Pi Zero Plus2, Orange Pi One Plus, Pine64 LTS, Banana Pi M2+ H5, 64-bit Banana Pi M2+ H3, ASUS Tinker Board S, RockPro64, Rock960, and ROC-RK-3399-PC. Qualcomm Snapdragon 835 SoC support along with the HiSilicon Hi3670, many NVIDIA Tegra improvements, GTA04A5 phone support, and more. Cross-hyperthread Spectre V2 mitigation with Intel STIBP. Better Intel IOMMU debugging with DebugFS support. Minor work on the IBM s390 architecture. Faster context switching on IBM POWER9. Scheduler improvements that should benefit asymmetric CPU systems like ARM big.LITTLE processors. Early work on AMD Zen 2 CPU enablement while more is on the way for future kernel cycles. AMD/Intel x86 CPUs now have nested virtualization enabled by default for KVM. A new CPU architecture port is for C-SKY 32-bit CPUs as another Chinese CPU architecture. Support for the Hygon Dhyana CPUs that are the new Chinese data center processors based on AMD Zen. The Cedrus VPU driver has been mainlined along with a new media request API. Virtual KMS (VKMS) has initial cursor and GEM support. Qualcomm Adreno A6xx performance improvements with the Freedreno MSM DRM code. The NVIDIA Xavier "Tegra194" SoC has initial display support. The open-source NVIDIA Nouveau driver has initial HDMI 2.0 support. The Intel DRM driver now has full PPGTT support for Haswell/Ivy/Valley View hardware. Continued work on the Intel Icelake "Gen 11" graphics support. GPUVM performance improvements for the AMDGPU kernel driver. VCN JPEG acceleration for Raven Ridge APUs in conjunction with Mesa 18.3 user-space code. The AMD Vega 20 7nm workstation GPU support is now largely squared away for when this graphics card will be released in the months ahead. AMD Picasso APU support as well as Raven 2 APU support. The Linux Kernel 4.20 is reaching its RC and is full of goodies including support for those iot boards like orange pi, and an start point at code part that is going to support the new AMD processors on a future, curious about whats inside? check it out: ![]()
