The matrix of adapters and domains configured in a guest's APCB may differ from the matrix of adapters and domains assigned to the matrix mdev, so this patch introduces a sysfs attribute to display the matrix of adapters and domains that are or will be assigned to the APCB of a guest that is or will be using the matrix mdev. For a matrix mdev denoted by $uuid, the guest matrix can be displayed as follows: cat /sys/devices/vfio_ap/matrix/$uuid/guest_matrix Signed-off-by: Tony Krowiak <akrowiak@linux.ibm.com> Reviewed-by: Jason J.
