Hi, I am new to writing pci sriov drivers. So i could use your help and expertise here.... As I understand once sriov is enabled, the PF driver can access the PF(Physical Function) configuration space, BAR(MMIO) etc and the VF driver can access the VF(Virtual Function) configuration space, BAR(MMIO)... Is it possible for a PF driver to access the VF config space, BAR(MMIO)? If yes, can you please point me as to what needs to be done in order to do it(existing driver sources will be really helpful). Now as to why this requirement is if the PF driver is ready and the VF driver is still under development, and I want to simulate the VF functionality from PF itself. It would be of immense help to me if anyone can help me understand my aforementioned query. Thanks a lot!!!
