The VME bridge drivers do not provide a user space API. They register with the VME core, which provides a kernel space API. This API is documented in "drivers/staging/vme/vme_api.txt". > What major+minor numbers should I use for mknod ? > If you are using udev, the device nodes will be automatically created. > How can I access the VME using this driver ? > Using the in kernel API. > Must I use CONFIG_VME_USER=y also ? > Tf you want access from user space, that module provides some basic access to the VME bus.
