In linux kernel since version 6.8 (release Date: 2024-03-10)  
Allows exposure of VFIO device internals. This option enables
the use of debugfs by VFIO drivers as required. The device can
cause the VFIO code create a top-level debug/vfio directory
during initialization, and then populate a subdirectory with
entries as required.
