Kernel Log: native KVM tool, new kernels galore

Filed under
Linux

In late March, Pekka Enberg announced on the LKML the development of a native KVM tool. This tool emulates some of the hardware components that guest systems access during operation; in KVM virtualisation, this task is nowadays mostly handled by a QEMU derivative, created and maintained as part of the KVM project. The KVM code within the kernel works in close co-operation with this emulation code, ensuring that the required processor resources are allocated; however, a few hardware components such as the interrupt controller are emulated by the KVM kernel code itself, because this considerably enhances performance.

In his email, Enberg writes that his aim was to create a light-weight and clean KVM emulation implementation that can boot Linux guests. The developer said that the tool is "[...] just a hobby, won't be big and professional like QEMU [...]" – a play on the words Linus Torvalds used in his first email about the development of Linux.

Windows 10 vs. Linux Radeon Software Performance, Including AMDGPU-PRO & RadeonSI

As alluded to earlier and on Twitter, the past few days I have been working on a fresh Windows 10 vs. Ubuntu Linux graphics/gaming performance comparison. This time it's looking at the latest Radeon performance using an R9 Fury and RX 480. Tests on Windows were obviously done with Radeon Software Crimson Edition while under Linux were the two latest AMD/RTG Linux driver options: the hybrid AMDGPU-PRO driver and the fully open-source driver via Linux 4.8 and Mesa 12.1-dev.
