The PF driver issues a DMAE to retrieve the request from the VM memory (the Ghost Physical Address of the request is contained in the interrupt. The PF driver uses the GPA in the DMAE request, which is translated by the IOMMU to the correct physical address). The request which arrives is examined to recognize the sending VF. The PF driver allocates a workitem to handle the VF Operation (vfop). Signed-off-by: Ariel Elior Signed-off-by: Eilon Greenstein Signed-off-by: David S. Miller --- Reading git-diff-tree failed
