GoKawiilLemonSeed Studio runs unmodified Linux amdgpu driver on iPad via PCIDriverKit
LemonSeed Studio is an iPad app that embeds the unmodified upstream Linux amdgpu and amdkfd driver as a PCIDriverKit extension, allowing it to control an AMD GPU connected through a Thunderbolt enclosure. The app also bundles the LemonSeed Engine for on-device LLM inference running on that GPU via its HSA runtime, plus amdgpu_mtopg for live GPU telemetry. The project's source is available via git with recursive submodules, and is dual-licensed under MIT or GPL-2.0-only.
