AMD Publishes Open-Source GIM Driver For GPU Virtualization, Radeon 'In The Roadmap

AMD has open-sourced its "GPU-IOV Module" for enabling SR-IOV-based virtualization on Instinct accelerators using the Linux kernel and KVM hypervisor, with features like GPU scheduling and VF/PF management. Notably, AMD plans to extend this virtualization support to client Radeon GPUs. Phoronix reports: The AMD GPU-IOV Module is for the Linux kernel and for providing SR-IOV based hardware virtualization in conjunction with the KVM hypervisor. GIM provides the GPU IOV virtualization, virtual function (VF) configuration and enablement, GPU scheduling for world switch, hang detection and FLR reset, and PF/VF handshake capabilities. Initially the AMD GIM driver is for the Instinct MI300X hardware and tested atop Ubuntu 22.04 LTS with ROCm 6.4. Those interested can find the AMD GIM code currently via GitHub. It's not laid out in the repository or any other public communications I've seen what any upstreaming plans are for this GIM driver to get it into the mainline Linux kernel.Read more of this story at Slashdot.
