AMD Begins Sending In "New Stuff" For Their Graphics Driver In Linux 6.19

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:
