Device Memory "DMEM" Cgroup Support Ready For Linux 6.14 To Allow Limiting GPU vRAM

This would be handy as heck for multi-tenant HPC systems... but I seriously doubt that Nvidia will ever deign to use TTM in their Linux driver.

I look forwards to the day HPC clouds can be non-nvidia. This is probably the most important piece to allow containerization of GPU workloads. (might also be useful for limiting VM VRAM usage in the case of native contexts?)

This would be super useful for Asahi Linux. I hope Asahi implements this soon

Phoronix: Device Memory "DMEM" Cgroup Support Ready For Linux 6.14 To Allow Limiting GPU vRAM

A pull request submitted this week to DRM-Next ahead of the upcoming Linux 6.14 cycle is introducing the notion of device memory "DMEM" to cgroup with the main intended use being to restrict device memory usage based on the cgroup hierarchy such as for graphics cards with their dedicated vRAM...
