Recently, a report broke that AMD was not too keen on extending Windows 10 support to its newest Strix Point parts. The company has now officially confirmed that that is indeed the case.
AMD began submitting Zen 5 patches for Linux this time last year and have been steadily submitting in anticipation of Zen 5 / Ryzen 9000.
So technically they’ve already released Linux support.
Edit: Proof from kernel.org showing Zen 5 named specifically.
Edit: I’m a dumbass. Ryzen AI 300 isn’t on Zen 5 but XDNA 2. XDNA support has been open sourced by AMD on GitHub and, according to a developer, they are trying to get it upstream too. The are committing to that repo all the time so I wouldn’t be surprised their XDNA 2 branch is merged in time for release.
