Valve Funds Port of Open-Source RADV Vulkan Driver to Windows
Key points
- Valve is sponsoring Collabora to port RADV to Windows.
- RADV is an open-source Mesa Vulkan driver for AMD GPUs.
- The port relies on AMD's official Windows kernel driver.
- The effort has enabled games like Counter-Strike 2 to run.
- It offers a shared codebase and easier debugging across platforms.
Open-Source Graphics Driver Comes to Windows
Valve is funding Collabora developers to port the open-source RADV Vulkan driver to Windows. RADV is the open-source Mesa Vulkan driver for AMD GPUs and has become a core part of the Linux graphics stack, with AMD consolidating its open-source efforts around it.
This port aims to provide Windows users with the same open-source Vulkan implementation available on Linux. The initiative has already shown results, with games like Counter-Strike 2 running on the ported driver.
Technical Challenges and Approach
A significant challenge in porting RADV to Windows involves integrating it with the AMD Radeon Software Windows kernel driver. The current work does not involve porting the AMDGPU Linux kernel graphics driver to Windows; instead, it adapts RADV to rely on AMD's official Windows kernel driver.
This adaptation requires understanding the proprietary kernel driver's data structures and other elements, which has involved reverse engineering. The effort builds on groundwork laid by Faith Ekstrand and leverages improvements in Windows 10 and WDDM 2.0, which better separate userspace and kernel-level driver components.
Benefits of a Cross-Platform Driver
Bringing an open-source Vulkan driver to Windows offers several advantages. These include a shared codebase across platforms, which can lead to easier debugging and experimentation. It also promises faster turnaround on fixes and provides a path for the community, including game developers, to report problems or contribute improvements that benefit users on both Linux and Windows.
This development provides an alternative to AMD's proprietary Windows drivers, potentially offering more flexibility and development opportunities for graphics on Windows.
