AMD on Friday sent in their first patch of AMDGPU kernel graphics driver changes they are ready to begin queuing in the DRM-Next tree until the Linux 6.19 merge window kicks off in December and leading to a stable release around February.
With this being the first of a few pull requests of new AMDGPU (and AMDKFD) material destined for Linux 6.19, it’s not too particularly noteable. This “new stuff for 6.19” includes continued work by AMD around SR-IOV capabilities for GPU virtualization, a variety of Display Core Next (DCN) updates for their display IP block, seemingly never-ending DisplayPort Multi-Stream Transport (DP MST) fixes, and more. For enterprise users is also a new RAS framework that may interest some while for desktop/laptop users there are some suspend improvements that may be helpful.
On the whole this pull request isn’t too particularly exciting for users at large. The highlights are:
