AMD Working on RDNA3 User-Mode Graphics Sequence for Linux GPU Driver


A remark request patch sequence submitted by AMD Linux graphics driver engineers forward of the vacations implements help for person mode queues with Radeon RX 7000 “Navi 3x” graphics playing cards and newer.

Patches implement user-mode graphics queues for Navi 3x and AMDGPU Linux DRM driver for future GPUs. The main focus is on permitting direct workload submission from a userspace graphics course of with AMDGPU graphics content material. Conversely, this direct workload dispatch from userspace graphics contexts can lead to higher efficiency and simpler administration for customized/fullscreen graphics functions/video games.

AMD’s ROCm computing stack has been round since final yr user-mode queues implemented for computing whereas this job is now on the graphics facet.

Some features of the userspace API for this AMDGPU graphics user-mode queues implementation haven’t but been clarified, however for these on this work, see the userspace API. RFC patch series for preliminary examine.
