Projecting a WDDM compatible abstraction for the GPU inside of Linux allowed us to recompile and bring our premiere graphics API to Linux when running in WSL.
#WINDOWS CUDA EMULATOR CODE#
As we work on upstreaming this new driver, source code is available in Microsoft’s official Linux kernel branch for WSL 2. Dxgkrnl Linux edition is being made open source and shared back with the community.
#WINDOWS CUDA EMULATOR DRIVER#
Note that the distro needs to be running in WSL version 2 mode ( wsl –set-version 2) in order to get access to the GPU.Īlthough they share a name, the version of dxgkrnl inside of the Linux kernel is a clean room implementation of a Linux GPU driver based on our GPU-PV protocol and doesn’t share anything else in common with its similarly named Windows counterpart.

If a Linux application is alone on a GPU, it can consume all its resources!Īssuming you have the right GPU driver installed on the Windows host, /dev/dxg is automatically exposed and available to any WSL distro installed without having to install any additional packages. There are basically no differences between two Windows applications sharing a GPU versus a Linux and a Windows application sharing the same GPU. The sharing is completely dynamic based on who needs what.
There is no partitioning of resources between Linux and Windows or limit imposed on Linux applications. If the host has multiple GPUs, all GPUs are projected and available to the Linux environment (assuming all of these GPUs are running WDDMv2.9 drivers).Īpplications running inside of the Linux environment have the same access to the GPU as native applications on Windows. Dxgkrnl inside of the Linux kernel connects over the VM Bus to its big brother on the Windows host and uses this VM bus connection to communicate with the physical GPU. dev/dxg exposes a set of IOCTL that closely mimic the native WDDM D3DKMT kernel service layer on Windows. Introducing dxgkrnl (Linux Edition)ĭxgkrnl is a brand-new kernel driver for Linux that exposes the /dev/dxg device to user mode Linux.

The projected abstraction of the GPU follows closely the WDDM GPU abstraction model, allowing API and drivers built against that abstraction to be easily ported for use in a Linux environment. This is achieved through a new Linux kernel driver that leverages the GPU-PV protocol to expose a GPU to user mode Linux. To bring support for GPU acceleration to WSL 2, WDDMv2.9 will expand the reach of GPU-PV to Linux guests. Windows running inside of a VM or container. Today this technology is limited to Windows guests, i.e. GPU-PV is now a foundational part of Windows and is used in scenarios like Windows Defender Application Guard, the Windows Sandbox or the Hololens 2 emulator. This technology is referred to as WDDM GPU Paravirtualization, or GPU-PV for short. This technology is integrated into WDDM (Windows Display Driver Model) and all WDDMv2.5 or later drivers have native support for GPU virtualization. Over the last few Windows releases, we have been busy developing client GPU virtualization technology. The purpose of this blog is to give you a glimpse of how this support is achieved and how the various pieces fit together.
In response to popular demand, these Linux applications and tools can now benefit from GPU acceleration. If you are a developer working on containerized workload that will be deployed in the cloud inside of Linux containers, you can develop and test these workloads locally on your Windows PC using the same native Linux tools you are accustomed to. What is WSL? WSL is an environment in which users can run their Linux applications from the comfort of their Windows PC. DirectX is coming to the Windows Subsystem for LinuxĪt //build 2020 we announced that GPU hardware acceleration is coming to the Windows Subsystem for Linux 2 (WSL 2).
