While the Linux 6.15 merge window only ended last weekend, new feature material is beginning to queue for DRM-Next ahead of the Linux 6.16 kernel cycle kicking off in late May or early June. A few notable patches so far have been submitted by way of DRM-Misc-Next.
Expect a lot of Linux graphics/display driver improvements to queue up in DRM-Next over the coming weeks in preparation for Linux 6.16. Yesterday DRM-Misc-Next submitted its first set of changes to DRM core and the random smaller Direct Rendering Manager drivers.
Part of this initial DRM-Misc-Next pull is the work covered yesterday with adding the Asahi Linux UAPI header file but not the actual driver itself for that Apple Silicon M1/M2 kernel graphics driver that will ultimately be upstreamed in the future.
This pull request also adds a new DRM panel quirk for the Zotac Gaming Zone handheld device that uses a 1080p portrait OLED screen and the quirk now marks the proper orientation of it.
The AMDXDNA driver was added back in Linux 6.14 for enabling the Ryzen AI NPU use under Linux. For Linux 6.16 the AMDXDNA driver is adding DMA-BUF import/export support. This allows for buffer object sharing with other drivers and opens up new use-cases moving forward for this AI/NPU accelerator driver with the DMA-BUF standard supported by the AMDGPU driver and various other kernel drivers for buffer sharing.
The Virtual KMS (VKMS) driver lands a patch series by José Expósito for adding more functionality to this driver in configuring additional displays. VKMS can now allow configuring and attaching multiple planes and CRTCs and other additional display capabilities.
Some of the other patches in this initial DRM-Misc-Next pull include documentation updates, splitting the HDMI audio code within the DRM bridge code to make DisplayPort audio work (will be used by the MSM Qualcomm Adreno driver and elsewhere), using 4K page table format for the Panfrost and Mediatek drivers, and various other changes.
See this drm-misc-next pull for the initial batch of features part sent in for DRM-Next in Linux 6.16. Expect a lot more feature work — especially for the more prominent Intel and AMD Radeon kernel graphics drivers to queue up over the coming weeks.
