 ========================
 
@@ -72,46 +80,8 @@ DRM Format Handling
 Dumb Buffer Objects
 ===================
 
-The KMS API doesn't standardize backing storage object creation and
-leaves it to driver-specific ioctls. Furthermore actually creating a
-buffer object even for GEM-based drivers is done through a
-driver-specific ioctl - GEM only has a common userspace interface for
-sharing and destroying objects. While not an issue for full-fledged
-graphics stacks that include device-specific userspace components (in
-libdrm for instance), this limit makes DRM-based early boot graphics
-unnecessarily complex.
-
-Dumb objects partly alleviate the problem by providing a standard API to
-create dumb buffers suitable for scanout, which can then be used to
-create KMS frame buffers.
-
-To support dumb objects drivers must implement the dumb_create,
-dumb_destroy and dumb_map_offset operations.
-
--  int (\*dumb_create)(struct drm_file \*file_priv, struct
-   drm_device \*dev, struct drm_mode_create_dumb \*args);
-   The dumb_create operation creates a driver object (GEM or TTM
-   handle) suitable for scanout based on the width, height and depth
-   from the struct :c:type:`struct drm_mode_create_dumb
-   <drm_mode_create_dumb>` argument. It fills the argument's
-   handle, pitch and size fields with a handle for the newly created
-   object and its line pitch and size in bytes.
-
--  int (\*dumb_destroy)(struct drm_file \*file_priv, struct
-   drm_device \*dev, uint32_t handle);
-   The dumb_destroy operation destroys a dumb object created by
-   dumb_create.
-
--  int (\*dumb_map_offset)(struct drm_file \*file_priv, struct
-   drm_device \*dev, uint32_t handle, uint64_t \*offset);
-   The dumb_map_offset operation associates an mmap fake offset with
-   the object given by the handle and returns it. Drivers must use the
-   :c:func:`drm_gem_create_mmap_offset()` function to associate
-   the fake offset as described in ?.
-
-Note that dumb objects may not be used for gpu acceleration, as has been
-attempted on some ARM embedded platforms. Such drivers really must have
-a hardware-specific ioctl to allocate suitable buffer objects.

+ * DOC: overview
+ *
+ * The KMS API doesn't standardize backing storage object creation and leaves it
+ * to driver-specific ioctls. Furthermore actually creating a buffer object even
+ * for GEM-based drivers is done through a driver-specific ioctl - GEM only has
+ * a common userspace interface for sharing and destroying objects. While not an
+ * issue for full-fledged graphics stacks that include device-specific userspace
+ * components (in libdrm for instance), this limit makes DRM-based early boot
+ * graphics unnecessarily complex.
+ *
+ * Dumb objects partly alleviate the problem by providing a standard API to
+ * create dumb buffers suitable for scanout, which can then be used to create
+ * KMS frame buffers.
+ *
+ * To support dumb objects drivers must implement the dumb_create,
+ * dumb_destroy and dumb_map_offset operations from struct &drm_driver. See
+ * there for further details.
+ *
+ * Note that dumb objects may not be used for gpu acceleration, as has been
+ * attempted on some ARM embedded platforms. Such drivers really must have
+ * a hardware-specific ioctl to allocate suitable buffer objects.

-	 *    example is dual-pipe operations (which generally should be hidden

-	 *    reflects the nature of the possible update and returns true if and
-	 *    only if the update cannot be applied without tearing within one
-	 *    vblank on that CRTC. The core uses that information to reject

-	 *    at least pausing updates for a substantial amount of time) if
-	 *    userspace has disallowed that in its request.

-	 *  - The driver also does not need to repeat basic input validation

-	/**
-	 * @atomic_commit:
-	 *
-	 * This is the only hook to commit an atomic modeset update. The core
-	 * guarantees that @atomic_check has been called successfully before
-	 * calling this function, and that nothing has been changed in the
-	 * interim.
-	 *
-	 * See the documentation for struct &drm_atomic_state for how exactly
-	 * an atomic modeset update is described.
-	 *
-	 * Drivers using the atomic helpers can implement this hook using
-	 * drm_atomic_helper_commit(), or one of the exported sub-functions of
-	 * it.
-	 *
-	 * Nonblocking commits (as indicated with the nonblock parameter) must
-	 * do any preparatory work which might result in an unsuccessful commit
-	 * in the context of this callback. The only exceptions are hardware
-	 * errors resulting in -EIO. But even in that case the driver must
-	 * ensure that the display pipe is at least running, to avoid
-	 * compositors crashing when pageflips don't work. Anything else,
-	 * specifically committing the update to the hardware, should be done
-	 * without blocking the caller. For updates which do not require a
-	 * modeset this must be guaranteed.
-	 *
-	 * The driver must wait for any pending rendering to the new
-	 * framebuffers to complete before executing the flip. It should also
-	 * wait for any pending rendering from other drivers if the underlying
-	 * buffer is a shared dma-buf. Nonblocking commits must not wait for
-	 * rendering in the context of this callback.
-	 *
-	 * An application can request to be notified when the atomic commit has
-	 * completed. These events are per-CRTC and can be distinguished by the
-	 * CRTC index supplied in &drm_event to userspace.
-	 *
-	 * The drm core will supply a struct &drm_event in the event
-	 * member of each CRTC's &drm_crtc_state structure. See the
-	 * documentation for &drm_crtc_state for more details about the precise
-	 * semantics of this event.
-	 *
-	 * NOTE:
-	 *
-	 * Drivers are not allowed to shut down any display pipe successfully
-	 * enabled through an atomic commit on their own. Doing so can result in
-	 * compositors crashing if a page flip is suddenly rejected because the
-	 * pipe is off.
-	 *
-	 * RETURNS:
-	 *
-	 * 0 on success or one of the below negative error codes:
-	 *
-	 *  - -EBUSY, if a nonblocking updated is requested and there is
-	 *    an earlier updated pending. Drivers are allowed to support a queue
-	 *    of outstanding updates, but currently no driver supports that.
-	 *    Note that drivers must wait for preceding updates to complete if a
-	 *    synchronous update is requested, they are not allowed to fail the
-	 *    commit in that case.
-	 *
-	 *  - -ENOMEM, if the driver failed to allocate memory. Specifically
-	 *    this can happen when trying to pin framebuffers, which must only
-	 *    be done when committing the state.
-	 *
-	 *  - -ENOSPC, as a refinement of the more generic -ENOMEM to indicate
-	 *    that the driver has run out of vram, iommu space or similar GPU
-	 *    address space needed for framebuffer.
-	 *
-	 *  - -EIO, if the hardware completely died.
-	 *
-	 *  - -EINTR, -EAGAIN or -ERESTARTSYS, if the IOCTL should be restarted.
-	 *    This can either be due to a pending signal, or because the driver
-	 *    needs to completely bail out to recover from an exceptional
-	 *    situation like a GPU hang. From a userspace point of view all errors are
-	 *    treated equally.
-	 *
-	 * This list is exhaustive. Specifically this hook is not allowed to
-	 * return -EINVAL (any invalid requests should be caught in
-	 * @atomic_check) or -EDEADLK (this function must not acquire
-	 * additional modeset locks).

+	 * interim.
+	 *
+	 * See the documentation for struct &drm_atomic_state for how exactly

+	 * it.
+	 *
+	 * Nonblocking commits (as indicated with the nonblock parameter) must
+	 * do any preparatory work which might result in an unsuccessful commit
+	 * in the context of this callback. The only exceptions are hardware
+	 * errors resulting in -EIO. But even in that case the driver must
+	 * ensure that the display pipe is at least running, to avoid
+	 * compositors crashing when pageflips don't work. Anything else,
+	 * specifically committing the update to the hardware, should be done
+	 * without blocking the caller. For updates which do not require a
+	 * modeset this must be guaranteed.
+	 *
+	 * The driver must wait for any pending rendering to the new
+	 * framebuffers to complete before executing the flip. It should also
+	 * wait for any pending rendering from other drivers if the underlying
+	 * buffer is a shared dma-buf. Nonblocking commits must not wait for
+	 * rendering in the context of this callback.
+	 *
+	 * An application can request to be notified when the atomic commit has
+	 * completed. These events are per-CRTC and can be distinguished by the
+	 * CRTC index supplied in &drm_event to userspace.
+	 *
+	 * The drm core will supply a struct &drm_event in the event
+	 * member of each CRTC's &drm_crtc_state structure. See the
+	 * documentation for &drm_crtc_state for more details about the precise
+	 * semantics of this event.
+	 *
+	 * NOTE:
+	 *
+	 * Drivers are not allowed to shut down any display pipe successfully
+	 * enabled through an atomic commit on their own. Doing so can result in
+	 * compositors crashing if a page flip is suddenly rejected because the
+	 * pipe is off.
+	 *
+	 * RETURNS:
+	 *
+	 * 0 on success or one of the below negative error codes:
+	 *
+	 *  - -EBUSY, if a nonblocking updated is requested and there is
+	 *    an earlier updated pending. Drivers are allowed to support a queue
+	 *    of outstanding updates, but currently no driver supports that.
+	 *    Note that drivers must wait for preceding updates to complete if a
+	 *    synchronous update is requested, they are not allowed to fail the
+	 *    commit in that case.
+	 *
+	 *  - -ENOMEM, if the driver failed to allocate memory. Specifically
+	 *    this can happen when trying to pin framebuffers, which must only
+	 *    be done when committing the state.
+	 *
+	 *  - -ENOSPC, as a refinement of the more generic -ENOMEM to indicate
+	 *    that the driver has run out of vram, iommu space or similar GPU
+	 *    address space needed for framebuffer.
+	 *
+	 *  - -EIO, if the hardware completely died.
+	 *
+	 *  - -EINTR, -EAGAIN or -ERESTARTSYS, if the IOCTL should be restarted.
+	 *    This can either be due to a pending signal, or because the driver
+	 *    needs to completely bail out to recover from an exceptional
+	 *    situation like a GPU hang. From a userspace point of view all errors are
+	 *    treated equally.
+	 *
+	 * This list is exhaustive. Specifically this hook is not allowed to
