-Plumb drm_atomic_state all over
--------------------------------
-
-Currently various atomic functions take just a single or a handful of
-object states (eg. plane state). While that single object state can
-suffice for some simple cases, we often have to dig out additional
-object states for dealing with various dependencies between the individual
-objects or the hardware they represent. The process of digging out the
-additional states is rather non-intuitive and error prone.
-
-To fix that most functions should rather take the overall
-drm_atomic_state as one of their parameters. The other parameters
-would generally be the object(s) we mainly want to interact with.
-
-For example, instead of
-
-.. code-block:: c
-
- int (*atomic_check)(struct drm_plane *plane, struct drm_plane_state *state);
-
-we would have something like
-
-.. code-block:: c
-
- int (*atomic_check)(struct drm_plane *plane, struct drm_atomic_state *state);
-
-The implementation can then trivially gain access to any required object
-state(s) via drm_atomic_get_plane_state(), drm_atomic_get_new_plane_state(),
-drm_atomic_get_old_plane_state(), and their equivalents for
-other object types.
-
-Additionally many drivers currently access the object->state pointer
-directly in their commit functions. That is not going to work if we
-eg. want to allow deeper commit pipelines as those pointers could
-then point to the states corresponding to a future commit instead of
-the current commit we're trying to process. Also non-blocking commits
-execute locklessly so there are serious concerns with dereferencing
-the object->state pointers without holding the locks that protect them.
-Use of drm_atomic_get_new_plane_state(), drm_atomic_get_old_plane_state(),
-etc. avoids these problems as well since they relate to a specific
-commit via the passed in drm_atomic_state.

+There's two related issues here
+
+- Cleanup up the various ->destroy callbacks, which often are all the same
+ simple code.
-Some of these date from the very introduction of KMS in 2008 ...
+- Lots of drivers erroneously allocate DRM modeset objects using devm_kzalloc,
+ which results in use-after free issues on driver unload. This can be serious
+ trouble even for drivers for hardware integrated on the SoC due to
+ EPROBE_DEFERRED backoff.
-- Make ->funcs and ->helper_private vtables optional. There's a bunch of empty
- function tables in drivers, but before we can remove them we need to make sure
- that all the users in helpers and drivers do correctly check for a NULL
- vtable.
+Both these problems can be solved by switching over to drmm_kzalloc(), and the
+various convenience wrappers provided, e.g. drmm_crtc_alloc_with_planes(),
+drmm_universal_plane_alloc(), ... and so on.
-- Cleanup up the various ->destroy callbacks. A lot of them just wrapt the
- drm_*_cleanup implementations and can be removed. Some tack a kfree() at the
- end, for which we could add drm_*_cleanup_kfree(). And then there's the (for
- historical reasons) misnamed drm_primary_helper_destroy() function.

+/**
+ * DOC: overview
+ *
+ * The GEM atomic helpers library implements generic atomic-commit
+ * functions for drivers that use GEM objects. Currently, it provides
+ * synchronization helpers, and plane state and framebuffer BO mappings
+ * for planes with shadow buffers.
+ *
+ * Before scanout, a plane's framebuffer needs to be synchronized with
+ * possible writers that draw into the framebuffer. All drivers should
+ * call drm_gem_plane_helper_prepare_fb() from their implementation of
+ * struct &drm_plane_helper.prepare_fb . It sets the plane's fence from
+ * the framebuffer so that the DRM core can synchronize access automatically.
+ *
+ * drm_gem_plane_helper_prepare_fb() can also be used directly as
+ * implementation of prepare_fb. For drivers based on
+ * struct drm_simple_display_pipe, drm_gem_simple_display_pipe_prepare_fb()
+ * provides equivalent functionality.
+ *
+ * .. code-block:: c

+ * as this would violate locking rules around dma_buf_vmap().
+ *
+ * The helpers for shadow-buffered planes establish and release mappings,
+ * and provide struct drm_shadow_plane_state, which stores the plane's mapping
+ * for commit-tail functons.
+ *
+ * Shadow-buffered planes can easily be enabled by using the provided macros
+ * %DRM_GEM_SHADOW_PLANE_FUNCS and %DRM_GEM_SHADOW_PLANE_HELPER_FUNCS.
+ * These macros set up the plane and plane-helper callbacks to point to the

*
* DRM planes have a few standardized properties:
*
+ * type:
+ * Immutable property describing the type of the plane.
+ *
+ * For user-space which has enabled the &DRM_CLIENT_CAP_ATOMIC capability,
+ * the plane type is just a hint and is mostly superseded by atomic
+ * test-only commits. The type hint can still be used to come up more
+ * easily with a plane configuration accepted by the driver.
+ *
+ * The value of this property can be one of the following:
+ *
+ * "Primary":
+ * To light up a CRTC, attaching a primary plane is the most likely to
+ * work if it covers the whole CRTC and doesn't have scaling or
+ * cropping set up.
+ *
+ * Drivers may support more features for the primary plane, user-space
+ * can find out with test-only atomic commits.
+ *
+ * Some primary planes are implicitly used by the kernel in the legacy
+ * IOCTLs &DRM_IOCTL_MODE_SETCRTC and &DRM_IOCTL_MODE_PAGE_FLIP.
+ * Therefore user-space must not mix explicit usage of any primary
+ * plane (e.g. through an atomic commit) with these legacy IOCTLs.
+ *
+ * "Cursor":
+ * To enable this plane, using a framebuffer configured without scaling
+ * or cropping and with the following properties is the most likely to
+ * work:
+ *
+ * - If the driver provides the capabilities &DRM_CAP_CURSOR_WIDTH and
+ * &DRM_CAP_CURSOR_HEIGHT, create the framebuffer with this size.
+ * Otherwise, create a framebuffer with the size 64x64.
+ * - If the driver doesn't support modifiers, create a framebuffer with
+ * a linear layout. Otherwise, use the IN_FORMATS plane property.
+ *
+ * Drivers may support more features for the cursor plane, user-space
+ * can find out with test-only atomic commits.
+ *
+ * Some cursor planes are implicitly used by the kernel in the legacy
+ * IOCTLs &DRM_IOCTL_MODE_CURSOR and &DRM_IOCTL_MODE_CURSOR2.
+ * Therefore user-space must not mix explicit usage of any cursor
+ * plane (e.g. through an atomic commit) with these legacy IOCTLs.
+ *
+ * Some drivers may support cursors even if no cursor plane is exposed.
+ * In this case, the legacy cursor IOCTLs can be used to configure the
+ * cursor.
+ *

+ * Neither primary nor cursor.

+ * Overlay planes are the only planes exposed when the
