Scalable Vector Extensions (SVE) is ARM’s latest SIMD extension to their instruction set, which was announced back in 2016. A follow-up SVE2 extension was announced in 2019, designed to incorporate all functionality from ARM’s current primary SIMD extension, NEON (aka ASIMD).
Despite being announced 5 years ago, there is currently no generally available CPU which supports any form of SVE (which excludes the [Fugaku supercomputer](https://www.fujitsu.com/global/about/innovation/

| What Is OpenGL? | |
| OpenGL is a Graphics rendering API which is operating system independent, window system independent and has high-quality color images composed of geometric and image primitives. | |
| OpenGL APIs can use following … | |
| Gl | |
| OpenGL API implementation (http://www.opengl.org) | |
| Glu | |
| OpenGL Utility | |
| Glut – GLUT (OpenGL Utility Toolkit) – Glut is portable windowing API and it is not officially part of OpenGL. | |

This guide is for achieving PCI-Passthrough with Intel 7700k and AMD RX 580. My host OS is Manjaro KDE edition, and guest is Windows 10.
| Device Type | Device |
|---|---|
| CPU | Intel Core i7-7700K |
| Motherboard | ASUS Prime Z270P |
| RAM | Corsair Vengeance (DDR4 3000 MHz) |
| GPU (Host) | Intel HD Graphics |
This is mainly a notes dump and should be used for reference. This guide assumes:
Limitations of the qemu-system-aarch64 emulator on x86 include only being able to emulate one CPU and no KVM support.
