During the heyday of NPU (Neural Processing Unit) technology in prior years, AMD also integrated a comparable design into its chips. However, the upcoming Linux kernel—potentially designated as Linux 7.0 (though the version number might revert to Linux 6.20)—will no longer support AMD's unreleased NPU2 hardware. AMD engineer Lizhi Hou has already excised the related support code from the AMDXDNA open-source driver patch released last week, given that the NPU2 never reached the market and is now considered obsolete. Nonetheless, this move does not signal AMD's retreat from AI-related capabilities in the Linux kernel. The NPU2 is distinct from the XDNA2 architecture employed in current Ryzen processors, which is widely utilized in the Ryzen AI 300 series and will continue to receive support.
