Linux 7.3 To Land Initial Code Improving vRAM Management, More Improvements Coming
The Linux 7.3 kernel will introduce initial code to improve vRAM management, with further improvements still being worked on for upstreaming into a future mainline Linux kernel release.

The Linux 7.3 kernel will improve vRAM management, with the initial patches already shipping in the SteamOS kernel. Further improvements are still being worked on for upstreaming into a future mainline Linux kernel release.
Imagine you're playing a game on your computer, and it needs a lot of memory to run smoothly. But your computer only has a certain amount of memory available. The Linux team is working on a way to make the game use less memory, so it can still run smoothly even if it's using up all the available memory. This is called 'vRAM management.' It's like a game of Tetris, where the computer is trying to fit all the pieces together to make the game run smoothly.

Initial Code Improvements for vRAM Management
The Linux 7.3 kernel will introduce initial code to improve vRAM management, a crucial aspect of the Linux gaming experience. This work is a direct result of Natalie Vock's patches for improving video memory management, which were laid out earlier this year. The initial patches have already been queued into DRM-Next and are slated for merging within the next two weeks for the Linux 7.13 merge window.
Further Improvements Still in the Works
While the initial code improvements are set to be introduced in the Linux 7.3 kernel, further improvements are still being worked on for upstreaming into a future mainline Linux kernel release. Natalie Vock's blog post highlights the nuances around video memory management, eviction handling, and testing that was done with Indiana Jones: The Great Circle. The post concludes that even with 1GB over-committed, the game ended up still being quite playable for an 8GB graphics card.
Implications and Future Directions
The work on improving vRAM management has significant implications for the Linux gaming experience. With the initial code improvements set to be introduced in the Linux 7.3 kernel, further improvements are still being worked on for upstreaming into a future mainline Linux kernel release. This branch, as 'vramstuff-rebase', has all those patches for those wanting to test it right now outside of the SteamOS world. The blog post highlights the measures that drivers (particularly, the kernel driver) can take to make overcommit work as fast as possible, and even applications can do their part in coordinating with the driver stack to mitigate the effects of their memory being evicted.
Key points
- The Linux 7.3 kernel will introduce initial code to improve vRAM management.
- Further improvements are still being worked on for upstreaming into a future mainline Linux kernel release.
- The work on improving vRAM management has significant implications for the Linux gaming experience.
- The initial code improvements are set to be introduced in the Linux 7.3 kernel.
- Further improvements are still being worked on for upstreaming into a future mainline Linux kernel release.
If this development plays out positively, it could lead to better performance and a more seamless gaming experience for users with limited vRAM. The initial code improvements are set to be introduced in the Linux 7.3 kernel, and further improvements are still being worked on for upstreaming into a future mainline Linux kernel release.
However, there are still risks and challenges associated with vRAM management. If the wrong thing ends up in CPU RAM, it can cause significant slowdowns. Additionally, the measures that drivers and applications can take to mitigate the effects of memory being evicted may not always be effective.
