There was a problem hiding this comment.
I missed in the last review, but can we have this VFTOKEN environment variable guide documentation to somewhere like vfio_pci_open API? This API does not totally represent the vfio itself due to it might be about iommufd, it should be documented somewhere for users to give their own VFTOKEN.
Add a set of utility functions operating on sysfs to deal with various aspects of SR-IOV Virtual Functions and their Physical Functions. Signed-off-by: Klaus Jensen <[email protected]>
If the physical function is bound to vfio-pci, it (and its VFs) must be opened using a VF "token". Allow this to be passed in a VFTOKEN environment variable. Signed-off-by: Klaus Jensen <[email protected]>
Add support for Virtualization Management through a set of helpers. Signed-off-by: Klaus Jensen <[email protected]>

Add support for SR-IOV within vfio (
vf_tokenand so on). Also add a set of helpers invfn/nvme/ctrl.hto assist with configuring secondary controllers (that may or may not be SR-IOV VFs).This builds on the patches from PR #20.
