No, Intel UHD Graphics 770 Never will work (4680).

 

Intel UHD Graphics 770 is based on Intel's 12.2 Architecture instead of the DG1 12.1 architecture.

 

Only Tigerlake, DG1, and Rocketlake has a chance by hacking the Iris XE driver for DG1 class cards to bypass compat checks.

 

 

 

 

 

Is it possible to reverse engineer?🥲

so using mesa for gt2:

 

GFX12_GT_FEATURES(2)

GFX12_FEATURES(2,1,8)

.num_subslices = 6

.gt = 2

.num_slices = 1

.l3_banks = 8

.max_eus_per_subslice = 16
