Hence, the first mainline +version of Nova will be a stub driver which helps establishing the necessary +infrastructure in other subsystems (notably PCI and DRM). + +## Contact + +To contact the team and / or participate in development, please use the mailing +list: nouveau@lists.freedesktop.org + + +## Resources + +- [Official Source Tree](https://gitlab.freedesktop.org/drm/nova) +- [Announcement E-Mail](https://lore.kernel.org/dri-devel/Zfsj0_tb-0-tNrJy@cassiopeiae/) + +In the source tree, the driver lives in `drivers/gpu/drm/nova`. + + +## Status + +Currently, Nova is just a stub driver intended to lift the bindings necessary +for a real GPU driver into the (mainline) kernel. + +Currently, those efforts are mostly focused on getting bindings for PCI, DRM +and the Device (driver) model upstream. + +It can be expected that, as the driver continues to grow, various other abstractions +will be needed. + + +## Utilized Common Rust Infrastructure + +Nova depends on the Rust for Linux `staging/*` [branches](Branches.md). + + +## Contributing + +As with every real open source program, help and participation is highly welcome! + +As the driver is very young, however, it is currently difficult to assign tasks +to people. Many things still have to settle until a steadily paced workflow +produces atomic work topics a new one can work on. + +If you really want to jump in immediately regardless, here are a few things you +can consider: + +- Most work to do right now is with more bindings for Rust. Notably, this + includes the device driver model, DRM and PCI. If you have expertise there, + have a look at the existing code in the [topic branches](Branches.md) and see + if there's something you can add or improve. +- Feel free to go over Nova's code base and make suggestions or send patches, + for example for improved comments, grammar fixes, improving code readability + etc. + + +Happy hacking!
