AMD recently [1]upstreamed Linux support for their next-gen AIE4 NPU . That next-gen AMD NPU support is expected to [2]premiere in Linux 7.2 while this week an interesting new patch series has surfaced for [3]SR-IOV support with those upcoming neural processing units.

A new patch series this week provides Single Root I/O Virtualization (SR-IOV) Virtual Function support for AMD's upcoming AIE4 platform with the AMDXDNA accelerator driver. This appears to be the first time any hardware supported by the AMDXDNA driver has SR-IOV support as I hadn't found any "vf" references in the AIE2 code paths of the driver either nor saw any other AMDXDNA patches previously around SR-IOV.

This SR-IOV support for AMDXDNA could let guest virtual machines tap the power of the Ryzen AI NPU for AI workloads. Interesting to see this SR-IOV support happening for AMDXDNA. Granted, many Phoronix readers would much rather see SR-IOV support for consumer Radeon GPUs and much more AI/compute potential there within VMs and other practical use-cases.

Those interested can see [4]this patch series with all the initial SR-IOV VF bits for the AMDXDNA accelerator driver.
