📰 AMD Revives Linux Kernel Patches For Hardware-Accelerated vIOMMU Back in 2023 AMD posted hardware-accelerated virtualized IOMMU patches for the Linux kernel as a request for comments (RFC). In 2024 they then posted a second iteration of the AMD vIOMMU patches but then seemingly fell off the radar. This morning is now the first set of updated AMD vIOMMU patches sent out on the Linux kernel mailing list with the RFC tag now removed... 🔗 Source: https://www.phoronix.com/news/AMD-vIOMMU-2026-Linux #linux#amd#kernel

📰AMD Ryzen AI NPUs Are Finally Useful Under Linux For Running LLMs Over the past two years AMD has developed the AMDXDNA accelerator driver in the mainline Linux kernel for supporting the AMD Ryzen AI NPUs. But when it comes to user-space software on Linux actually able to leave the Ryzen AI NPUs it's been... extremely limited with nothing really useful besides some niche bits of code. Even AMD's own software like their GAIA on Linux has used Vulkan with their iGPUs rather than any NPU support. 🔗 Source: https://www.phoronix.com/news/AMD-Ryzen-AI-NPUs-Linux-LLMs #kernel#linux#amd
