67  * DRM_NOUVEAU_EXEC ioctl is called to submit an exec job.
69  * A VM_BIND job can be executed either synchronously or asynchronously. If
70  * exectued asynchronously, userspace may provide a list of syncobjs this job
72  * VM_BIND job finished execution. If executed synchronously the ioctl will
