Detailed Description

struct drm_i915_gem_vm_control - Structure to create or destroy VM.

DRM_I915_GEM_VM_CREATE -

Create a new virtual memory address space (ppGTT) for use within a context on the same file. Extensions can be provided to configure exactly how the address space is setup upon creation.

The id of new VM (bound to the fd) for use with I915_CONTEXT_PARAM_VM is returned in the outparam @id.

An extension chain maybe provided, starting with @extensions, and terminated by the @next_extension being 0. Currently, no extensions are defined.

DRM_I915_GEM_VM_DESTROY -

Destroys a previously created VM id, specified in @vm_id.

No extensions or flags are allowed currently, and so must be zero.
