Linux kernel 4.10 provides full GPU virtualization

final version 4.10 of the Linux kernel has been released after eight release candidates the

Linus Torvalds . Most important new feature is the GPU virtualization technology Intel GVT-g for kernel-based virtual machines (KVMGT). The new kernel improved ARM but also the support for -based devices such as Google nexus 5 X and nexus 6 p.

Linux-Maskottchen Tux (Grafik: Larry Ewing) Intel GVT-g provides a so-called mediated-pass-through, which in turn allows a full GPU virtualization processors from the fourth generation of Intel Core (HASWELL). In contrast to the direct pass-through, KVMGT any virtualized guest system offers a fully virtualised GPU with all GPU features. While only parts of the performance critical resources are mapped directly, which nevertheless is a near-native graphics performance available.

the technology offers also the ability to run native graphics driver within a virtual machine. Because of the Hypersivor in performance critical tasks does not intervene, a good balance between performance, functionality, and sharing capabilities will be achieved.

release notes according to the new kernel is also “a testament to the efforts, the Android – and mainline kernel bringing together”. The version 4.10 therefore now supports the ARM SoCs of the Huawei nexus 6 p (angler), the LG nexus 5 X (Bullhead), the Android TV boxes Nexbox A1 and A95X, as well as several single-board computer.

in addition the kernel but also supports the Intel technology cache allocation. It allows you to set policies for the use of the level-2 and level-3 CPU cache. For example, real time tasks can be assigned to certain memory areas.

the new kernel version fixes many errors, including when dealing with different file systems such as F2FS, XFS, ext4, NFS and CIFS. The developers have improved but also the memory management. Other changes relate to areas such as virtualization, networking, graphics and security.

in addition, the kernel contains numerous new drivers for graphics hardware by Intel and AMD, storage and networking products, audio hardware, TV tuners, webcams and USB. Under the item “Drivers for tablets, touch screens, keyboards and mice” are found also the Microsoft -tablets surface starts the usually two-week phase of integration for kernel 3 and surface 4

with the release of Linux 4.10 4.11. It will appear likely to end of April or beginning of May.

benchmarks like SunSpider, Octopus or octane survived according to Google Developer Benedikt Meurer. A profiling of well-known Web pages have shown that the benchmark speedometer for the performance evaluation of browsers is still the best.
