Intel Linux Driver Adds New DG2 "G12" Graphics Variant
To date the Intel Linux graphics driver has supported Intel's DG2 "Alchemist" G10 and G11 sub-platforms/variants as the main designs to this point. However, at the end of last year we began seeing "G12" references surface in their compute stack and now the Intel open-source Linux kernel driver is formally preparing the DG2-G12 variant support.
Posted a few minutes ago were the first Intel "i915" Linux kernel graphics driver patches for bringing up the new G12 sub-platform.
The patch just deals with a dozen lines of code and doesn't really reveal any juicy details. For now it's just treated as a new sub-platform and sharing the existing workarounds as with DG2-G10 and DG2-G11.
The patch message does note:
Time will tell what more G10/G11 vs. G12 differences for DG2 Alchemist graphics hardware come as a result of future Linux driver patches. Given we are only seeing these DG2-G12 patches now, graphics processors using this sub-platform type presumably will not come until much later while Intel is still promoting by the end of Q1 that we should see the first Intel Arc graphics hardware shipping.

Intel DG2-G12 Linux driver support is on the way.

The patch message does note:
Another fork of the DG2 design has appeared, known as "DG2-G12;" let's add it as a new subplatform. As with G11, the GT stepping resets back to A0 (so a DG2-G12 A0 is similar, but not identical, to a DG2-G10 C0) but the display steppings continue to use the same numbering scheme as G10 and G11.
Some existing DG2 workarounds are starting to be extended to the DG2-G12 subplatform. So far only workarounds that were "permanent" for both DG2-G10 and DG2-G11 have been tagged for DG2-G12, but more stepping-specific workarounds are likely to show up in the future.
