Hello. I've found this old document,dated 2016,where the Linaro team says to have upstreamed the patches to passthru a gpu on arm64 for the boards that supporters the gicV3 specifications : https://old.linaro.org/blog/kvm-pciemsi-passthrough-armarm64/ Those patches work if we use qemu and kvm. They don't explain which arm64 boards are supported. I don't understand what is the context in which those patches work. And what's the situation today ? I presume that the board should have the PCIe bus ? Maybe boards like Ampere or ThunderX2 or the Radxa Orion O6 ? If I use those boards with qemu and kvm,could I make the passthru of the GPU ? Anyway,I presume that on that high level arm boards,the bhyve developer could add the necessary patches to allow the passthru of the gpu ? Are there some plans to do it ?
