Feature work on the DRM graphics driver changes for Linux 5.18 will be winding down shortly while some new drm-intel-gt-next changes were submitted this week. Arguably most significant with this pull request is the DG2-G12 sub-platform being added. DG2 "G12" references began appearing within Intel's open-source driver code toward the end of 2021 and then the Linux kernel patches appeared . DG2-G12 is a new varaint following the existing DG2-G10 and DG2-G11 targets supported already by the open-source Linux graphics driver code. The commit message calls DG2-G12 "another fork in the DG2 design." But otherwise not much is known yet about the DG2-G12 variant and not any exciting bits exposed from the kernel driver enablement.
Various changes were made to the Intel i915 driver to start the DG2-G12 new variant support of DG2/Alchemist.
This latest Intel pull request also adds more DG2/Alchemist driver workarounds, adds Raptor Lake C0 and D0 stepping details, and also has more improvements for running Intel discrete graphics on 64-bit Arm (AArch64) systems . There is also parallel submission work, improvements to the GuC handling code, and a vsriety of other low-level code improvements.
The full list of Intel patches this week ready to go for Linux 5.18 can be found via this pull request . The Linux 5.18 merge window should formally kick off in late March with the kernel then debuting as stable around late May.
