Bind amdgpu to SR-IOV virtual function

[Dennis Schridde]

Hello!

I investigating the virtualisation abilities of current AMD FirePro hardware; 
specifically how to securely pass a share of a GPU to one application (a Rkt/
Docker container). I already read vfio.txt and pci-iov-howto.txt, but they do 
not answer my questions. I was unable to find documentation on the process 
online, either.

1. How do I create VFs from a AMD FirePro PF? I saw an example using VMWare 
ESXi tools, where it is possible to specify RAM size and time-share, but I 
have not seen how that translates to modifying /sys/bus/pci/..., which is the 
method recommended for SR-IOV devices in pci-iov-howto.txt.

2. After having created VFs, is it possible to bind these to the host's amdgpu 
driver, so that I get multiple /dev/dri/card* device nodes?

3. Will passing these /dev/dri/card* device nodes into a Rkt/Docker container 
be enough for the AMD Radeon Pro OpenGL runtime to be able to use that card?

Best regards,
Dennis Schridde
