Detailed Description

struct drm_nouveau_vm_init - GPU VA space init structure

Used to initialize the GPU's VA space for a user client, telling the kernel which portion of the VA space is managed by the UMD and kernel respectively.

For the UMD to use the VM_BIND uAPI, this must be called before any BOs or channels are created; if called afterwards DRM_IOCTL_NOUVEAU_VM_INIT fails with -ENOSYS.
