Hopefully by Linux 6.1 the support will be fully ironed out and enabled by default.

With Linux 6.0 the Intel DG2 graphics cards will still require setting the i915.force_probe= module option for enabling the accelerated graphics support. Linux 6.0 seems to be the minimum viable version of the Linux kernel that is useful for upcoming Arc Graphics desktop hardware, but it's still not enabled by default.

In Linux 5.19 they began exposing the compute support to user-space and now for Linux 6.0 there is small BAR support and other necessary bits in place. Intel's open-source driver engineers have been busy working out the Intel DG2/Alchemist desktop Arc Graphics cards and Arctic Sound M. Much of this work is centered around bringing up the Intel Arc Graphics DG2/Alchemist discrete graphics cards and on the AMD side continued work around enabling RDNA3 and Instinct MI300 graphics processors. Direct Rendering Manager (DRM) subsystem maintainer David Airlie has submitted all of the open-source GPU/display driver updates for the Linux 6.0 (nee 5.20) merge window.
