-De-midlayer drivers
--------------------
-
-With the recent ``drm_bus`` cleanup patches for 3.17 it is no longer required
-to have a ``drm_bus`` structure set up. Drivers can directly set up the
-``drm_device`` structure instead of relying on bus methods in ``drm_usb.c``
-and ``drm_pci.c``. The goal is to get rid of the driver's ``->load`` /
-``->unload`` callbacks and open-code the load/unload sequence properly, using
-the new two-stage ``drm_device`` setup/teardown.
-
-Once all existing drivers are converted we can also remove those bus support
-files for USB and platform devices.
-
-All you need is a GPU for a non-converted driver (currently almost all of
-them, but also all the virtual ones used by KVM, so everyone qualifies).

+/**
+ * DOC: overview
+ *
+ * This library provides &struct drm_gem_vram_object (GEM VRAM), a GEM
+ * buffer object that is backed by video RAM. It can be used for
+ * framebuffer devices with dedicated memory. The video RAM can be
+ * managed with &struct drm_vram_mm (VRAM MM). Both data structures are
+ * supposed to be used together, but can also be used individually.
+ *
+ * With the GEM interface userspace applications create, manage and destroy
+ * graphics buffers, such as an on-screen framebuffer. GEM does not provide
+ * an implementation of these interfaces. It's up to the DRM driver to
+ * provide an implementation that suits the hardware. If the hardware device
+ * contains dedicated video memory, the DRM driver can use the VRAM helper
+ * library. Each active buffer object is stored in video RAM. Active
+ * buffer are used for drawing the current frame, typically something like
+ * the frame's scanout buffer or the cursor image. If there's no more space
+ * left in VRAM, inactive GEM objects can be moved to system memory.
+ *
+ * The easiest way to use the VRAM helper library is to call
+ * drm_vram_helper_alloc_mm(). The function allocates and initializes an
+ * instance of &struct drm_vram_mm in &struct drm_device.vram_mm . Use
+ * &DRM_GEM_VRAM_DRIVER to initialize &struct drm_driver and
+ * &DRM_VRAM_MM_FILE_OPERATIONS to initialize &struct file_operations;
+ * as illustrated below.
+ *
+ * .. code-block:: c
+ *
+ * struct file_operations fops ={
+ * .owner = THIS_MODULE,
+ * DRM_VRAM_MM_FILE_OPERATION
+ * };
+ * struct drm_driver drv = {
+ * .driver_feature = DRM_ ... ,
+ * .fops = &fops,
+ * DRM_GEM_VRAM_DRIVER
+ * };
+ *
+ * int init_drm_driver()
+ * {
+ * struct drm_device *dev;
+ * uint64_t vram_base;
+ * unsigned long vram_size;
+ * int ret;
+ *
+ * // setup device, vram base and size
+ * // ...
+ *
+ * ret = drm_vram_helper_alloc_mm(dev, vram_base, vram_size,
+ * &drm_gem_vram_mm_funcs);
+ * if (ret)
+ * return ret;
+ * return 0;
+ * }
+ *
+ * This creates an instance of &struct drm_vram_mm, exports DRM userspace
+ * interfaces for GEM buffer management and initializes file operations to
+ * allow for accessing created GEM buffers. With this setup, the DRM driver
+ * manages an area of video RAM with VRAM MM and provides GEM VRAM objects
+ * to userspace.
+ *
+ * To clean up the VRAM memory management, call drm_vram_helper_release_mm()
+ * in the driver's clean-up code.
+ *
+ * .. code-block:: c
+ *
+ * void fini_drm_driver()
+ * {
+ * struct drm_device *dev = ...;
+ *
+ * drm_vram_helper_release_mm(dev);
+ * }
+ *
+ * For drawing or scanout operations, buffer object have to be pinned in video
+ * RAM. Call drm_gem_vram_pin() with &DRM_GEM_VRAM_PL_FLAG_VRAM or
+ * &DRM_GEM_VRAM_PL_FLAG_SYSTEM to pin a buffer object in video RAM or system
+ * memory. Call drm_gem_vram_unpin() to release the pinned object afterwards.
+ *
+ * A buffer object that is pinned in video RAM has a fixed address within that
+ * memory region. Call drm_gem_vram_offset() to retrieve this value. Typically
+ * it's used to program the hardware's scanout engine for framebuffers, set
+ * the cursor overlay's image for a mouse cursor, or use it as input to the
+ * hardware's draing engine.
+ *
+ * To access a buffer object's memory from the DRM driver, call
+ * drm_gem_vram_kmap(). It (optionally) maps the buffer into kernel address
+ * space and returns the memory address. Use drm_gem_vram_kunmap() to
+ * release the mapping.
