On the AMD side there is gang submit support needed for reliable RADV Vulkan mesh shader support, new GPU IP blocks enabled for upcoming GPUs/APUs, new "mode2" reset support for RDNA2, and other low-level improvements. See today's Intel Arc Graphics A750/A770 Linux review for more information on these DG2 graphics cards hitting retail channels next week. I've already tried out the DRM-Next tree a few days ago with the new Arc Graphics A750 and A770 but didn't find any measurable difference compared to the Linux 6.0 state. There is updated DMC firmware for DG2, preemption workarounds, improved HDMI pixel clock handling, enabling DC5, and a variety of other changes for the new Intel Arc Graphics discrete GPUs.
There is also improved GPU firmware handling as part of the Intel changes and continued work on DG2/Alchemist graphics. Meteor Lake enablement on the graphics side remains ongoing but at least should all be settled upstream well before the Meteor Lake CPU launch in H2'2023. Meteor Lake features integrated graphics derived from DG2/Alchemist level capabilities. On the Intel i915 driver side there is more enablement work landing for Meteor Lake as the successor to Raptor Lake. As usual, much of the interesting display/graphics driver work is happening within the open-source Intel and AMD Radeon drivers. The Direct Rendering Manager (DRM) / Kernel Mode-Setting (KMS) driver updates have been submitted for the Linux 6.1 merge window.
