For Jetson TX2, and L4T version is 27.1, I open the vfio device through “make menuconfig”.
In “make menuconfig”, open VFIO_FRAMEWORK. Then I can see the /dev/vfio/ under TX2.
But, when I try to open the device through open(/dev/vfio/55, O_RDWR)), it failed.
The fail info is as below:
ERROR: vfio_create open /dev/vfio/55 failed
Aborted (core dumped)
How can I fix this issue?
