+ * DOC: VM_BIND/UNBIND ioctls
+ *
+ * DRM_I915_GEM_VM_BIND/UNBIND ioctls allows UMD to bind/unbind GEM buffer
+ * objects (BOs) or sections of a BOs at specified GPU virtual addresses on a
+ * specified address space (VM). Multiple mappings can map to the same physical
+ * pages of an object (aliasing). These mappings (also referred to as persistent
+ * mappings) will be persistent across multiple GPU submissions (execbuf calls)
+ * issued by the UMD, without user having to provide a list of all required
+ * mappings during each submission (as required by older execbuf mode).
+ *
+ * The VM_BIND/UNBIND calls allow UMDs to request a timeline out fence for
+ * signaling the completion of bind/unbind operation.
+ *
+ * VM_BIND feature is advertised to user via I915_PARAM_VM_BIND_VERSION.
+ * User has to opt-in for VM_BIND mode of binding for an address space (VM)
+ * during VM creation time via I915_VM_CREATE_FLAGS_USE_VM_BIND extension.
+ *
+ * VM_BIND/UNBIND ioctl calls executed on different CPU threads concurrently
+ * are not ordered. Furthermore, parts of the VM_BIND/UNBIND operations can be
+ * done asynchronously, when valid out fence is specified.
+ *
+ * VM_BIND locking order is as below.
+ *
+ * 1) vm_bind_lock mutex will protect vm_bind lists. This lock is taken in
+ *    vm_bind/vm_unbind ioctl calls, in the execbuf path and while releasing the
+ *    mapping.
+ *
+ *    In future, when GPU page faults are supported, we can potentially use a
+ *    rwsem instead, so that multiple page fault handlers can take the read
+ *    side lock to lookup the mapping and hence can run in parallel.
+ *    The older execbuf mode of binding do not need this lock.
+ *
+ * 2) The object's dma-resv lock will protect i915_vma state and needs
+ *    to be held while binding/unbinding a vma in the async worker and while
+ *    updating dma-resv fence list of an object. Note that private BOs of a VM
+ *    will all share a dma-resv object.
+ *
+ * 3) Spinlock/s to protect some of the VM's lists like the list of
+ *    invalidated vmas (due to eviction and userptr invalidation) etc.

+ * struct drm_i915_gem_vm_bind - VA to object mapping to bind.
+ *
+ * This structure is passed to VM_BIND ioctl and specifies the mapping of GPU
+ * virtual address (VA) range to the section of an object that should be bound
+ * in the device page table of the specified address space (VM).
+ * The VA range specified must be unique (ie., not currently bound) and can
+ * be mapped to whole object or a section of the object (partial binding).
+ * Multiple VA mappings can be created to the same section of the object
+ * (aliasing).
+ *
+ * The @start, @offset and @length must be 4K page aligned. However the DG2
+ * and XEHPSDV has 64K page size for device local memory and has compact page
+ * table. On those platforms, for binding device local-memory objects, the
+ * @start, @offset and @length must be 64K aligned.
+ *
+ * Error code -EINVAL will be returned if @start, @offset and @length are not
+ * properly aligned. In version 1 (See I915_PARAM_VM_BIND_VERSION), error code
+ * -ENOSPC will be returned if the VA range specified can't be reserved.
+ *
+ * VM_BIND/UNBIND ioctl calls executed on different CPU threads concurrently
+ * are not ordered. Furthermore, parts of the VM_BIND operation can be done
+ * asynchronously, if valid @fence is specified.
