I’m using CX7 VF for P2P purpose in virtual machine. Somehow the VF’s ATS capability status is always disabled.
The configuration steps are like following:
- Enable CX7 ATS_ENABLE and reset it to show the ATS capability
- Create VFs
- Bind VF to vfio-pci and start the virtual machine
- Check the ATS capability status on host and guest, both are disabled status
Same way works with PF. Did I miss sth here?
