XPDDS19: Implementing AMD MxGPU - Jonathan Farrell, Assured Information Security
0 likes408 views
Jon Farrell summarizes his experience implementing AMD MxGPU virtualization. He began by learning about MxGPU on GitHub and setting up an Ubuntu server with Xen. Initial setup involved building a custom kernel, blacklisting amdgpu, and enabling IOMMU. Guest preparation required installing a VNC server and driver. Difficulties included choosing the right Xen version, starting modules, kernel building, and MxGPU patches. Performance metrics were estimated based on similar benchmarks. Overall, Farrell learned about building Xen, custom kernels, guest VMs, and device passthrough with XL. He sees potential for this technology in cloud gaming platforms and Xen virtualization.

- 1. Implementing AMD MxGPU Jon Farrell, Software Engineer, AIS Inc.
- 2. Overview • Background • Getting Started • Initial Setup • Guest Prep • Difficulties • Performance • What I’ve learned • The Future • Questions
- 3. Background • BS in Computer Science from SUNY Binghamton • Currently with Assured Information Security, Inc. • Areas I’ve worked in: • Windows/Linux driver building and installation • Windows/Linux application development • Platform build system development • Linux graphics development with Qt • Now… Integration of AMD MxGPU into our OpenXT based platform
- 4. Getting Started • Git repository: https://github.com/GPUOpen-LibrariesAndSDKs/MxGPU-Virtualization • Important things to keep in mind • Ubuntu version recommended : 16.04.2 server • Kernel version recommended : Ubuntu 4.4.0-75-generic • Xen version recommended : Default for Ubuntu 16.04
- 5. Initial Setup • Github/docs/environment_setup • Install Xen • Building a custom kernel with patches • Blacklist amdgpu • Enable IOMMU • Build and install GIM • Catches: • Patches are for Ubuntu 4.4.0.75-generic kernel • Xen version from apt-get is a bit old?
- 6. Guest Prep • Github/docs/environment_setup • Guest IP • Install VNC server • Download driver (No direct download page anymore) • Search for your device • Select Guest Driver MxGPU Pass Through • Catches: • Safe mode remove / install
- 7. Difficulties • Building Xen – Which version?!? • Starting Xen modules (who knew) • Building my first kernel • MxGPU Patches • Pass through the vGPU and were done right? • Safe mode
- 8. Performance • No direct comparison metrics • What I would have liked to do • Unigine Heaven Fps (Guestimates) • MxGPU 4GB Mem 1080p • Medium : 40-60 fps • High : 20-40 fps • Benchmark from online with 1080p GTX 1050 Ti 4GB • Medium : 30-50 fps - avg 40 fps • High : 20-40 fps - avg 30 fps
- 9. What I’ve Learned • How to build Xen • Building a custom Linux Kernel • Setting up a guest VM for Xen • Using XL to pass through a device • Monitoring network traffic of a guest • Much more… • Don’t expect things to work out of the box
- 10. The Future • The Cloud • Google Stadia • Xen Platform • Users • Developer testing
