As usual, much of the DRM activity is around the Intel and AMD kernel graphics drivers. But there's also work to the various smaller drivers and a random assortment of other enhancements to this open-source graphics/display code. Some of the Linux 6.9 DRM highlights include:
- The Intel Xe DRM driver that was upstreamed in Linux 6.8 continues seeing a lot of feature work. The Xe driver has seen a new vRAM frequency sysfs interface, a new query for reading the GuC submission version, SR-IOV preparations, and implementing more code for Meteor Lake as well as Lunar Lake's Xe2 graphics.
- Intel's existing i915 DRM driver has seen new Arrow Lake and Alder Lake N PCI IDs, Intel Fastboot is now enabled everywhere , and DisplayPort tunneling and bandwidth allocation support.
- AMDGPU has continued work on RDNA3.5 "RDNA3 refresh" enablement.
- AMDGPU also continues seeing new IP blocks enabled that are likely for RDNA4 graphics processors.
- The RAS ACA Framework for AMD MI300 hardware .
- Continued AMDGPU work on color management and enabling the DC color block.
- Panel orientation quirk for the GPD Win Mini.
- The MSM DRM driver adds support for the Qualcomm Adreno A305B, A750, and A702 GPUs.
- The Rockchip DRM driver now supports HDMI on the RK3128 SoC.
- The Mediatek DRM driver has added display code for the MT8188 VDOSYS1.
- The Etnaviv DRM driver has been updated around the Vivante NPU IP support with the Mesa Teflon code in user-space.
