+Generic fbdev defio support
+---------------------------
+
+The defio support code in the fbdev core has some very specific requirements,
+which means drivers need to have a special framebuffer for fbdev. Which prevents
+us from using the generic fbdev emulation code everywhere. The main issue is
+that it uses some fields in struct page itself, which breaks shmem gem objects
+(and other things).
+
+Possible solution would be to write our own defio mmap code in the drm fbdev
+emulation. It would need to fully wrap the existing mmap ops, forwarding
+everything after it has done the write-protect/mkwrite trickery:
+
+- In the drm_fbdev_fb_mmap helper, if we need defio, change the
+ default page prots to write-protected with something like this::
+
+ vma->vm_page_prot = pgprot_wrprotect(vma->vm_page_prot);
+
+- Set the mkwrite and fsync callbacks with similar implementions to the core
+ fbdev defio stuff. These should all work on plain ptes, they don't actually
+ require a struct page. uff. These should all work on plain ptes, they don't
+ actually require a struct page.
+
+- Track the dirty pages in a separate structure (bitfield with one bit per page
+ should work) to avoid clobbering struct page.
+
+Might be good to also have some igt testcases for this.

+ * DOC: Branch device and port refcounting
+ *
+ * Topology refcount overview
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * The refcounting schemes for &struct drm_dp_mst_branch and &struct
+ * drm_dp_mst_port are somewhat unusual. Both ports and branch devices have
+ * two different kinds of refcounts: topology refcounts, and malloc refcounts.
+ *
+ * Topology refcounts are not exposed to drivers, and are handled internally
+ * by the DP MST helpers. The helpers use them in order to prevent the
+ * in-memory topology state from being changed in the middle of critical
+ * operations like changing the internal state of payload allocations. This
+ * means each branch and port will be considered to be connected to the rest
+ * of the topology until it's topology refcount reaches zero. Additionally,
+ * for ports this means that their associated &struct drm_connector will stay
+ * registered with userspace until the port's refcount reaches 0.
+ *
+ * Malloc refcount overview
+ * ~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * Malloc references are used to keep a &struct drm_dp_mst_port or &struct
+ * drm_dp_mst_branch allocated even after all of its topology references have
+ * been dropped, so that the driver or MST helpers can safely access each
+ * branch's last known state before it was disconnected from the topology.
+ * When the malloc refcount of a port or branch reaches 0, the memory
+ * allocation containing the &struct drm_dp_mst_branch or &struct
+ * drm_dp_mst_port respectively will be freed.
+ *
+ * For &struct drm_dp_mst_branch, malloc refcounts are not currently exposed
+ * to drivers. As of writing this documentation, there are no drivers that
+ * have a usecase for accessing &struct drm_dp_mst_branch outside of the MST
+ * helpers. Exposing this API to drivers in a race-free manner would take more
+ * tweaking of the refcounting scheme, however patches are welcome provided
+ * there is a legitimate driver usecase for this.
+ *
+ * Refcount relationships in a topology
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * Let's take a look at why the relationship between topology and malloc
+ * refcounts is designed the way it is.
+ *
+ * .. kernel-figure:: dp-mst/topology-figure-1.dot
+ *
+ * An example of topology and malloc refs in a DP MST topology with two
+ * active payloads. Topology refcount increments are indicated by solid
+ * lines, and malloc refcount increments are indicated by dashed lines.
+ * Each starts from the branch which incremented the refcount, and ends at
+ * the branch to which the refcount belongs to, i.e. the arrow points the
+ * same way as the C pointers used to reference a structure.
+ *
+ * As you can see in the above figure, every branch increments the topology
+ * refcount of it's children, and increments the malloc refcount of it's
+ * parent. Additionally, every payload increments the malloc refcount of it's
+ * assigned port by 1.
+ *
+ * So, what would happen if MSTB #3 from the above figure was unplugged from
+ * the system, but the driver hadn't yet removed payload #2 from port #3? The
+ * topology would start to look like the figure below.
+ *
+ * .. kernel-figure:: dp-mst/topology-figure-2.dot
+ *
+ * Ports and branch devices which have been released from memory are
+ * colored grey, and references which have been removed are colored red.
+ *
+ * Whenever a port or branch device's topology refcount reaches zero, it will
+ * decrement the topology refcounts of all its children, the malloc refcount
+ * of its parent, and finally its own malloc refcount. For MSTB #4 and port
+ * #4, this means they both have been disconnected from the topology and freed
+ * from memory. But, because payload #2 is still holding a reference to port
+ * #3, port #3 is removed from the topology but it's &struct drm_dp_mst_port
+ * is still accessible from memory. This also means port #3 has not yet
+ * decremented the malloc refcount of MSTB #3, so it's &struct
+ * drm_dp_mst_branch will also stay allocated in memory until port #3's
+ * malloc refcount reaches 0.
+ *
+ * This relationship is necessary because in order to release payload #2, we
+ * need to be able to figure out the last relative of port #3 that's still
+ * connected to the topology. In this case, we would travel up the topology as
+ * shown below.
+ *
+ * .. kernel-figure:: dp-mst/topology-figure-3.dot
+ *
+ * And finally, remove payload #2 by communicating with port #2 through
+ * sideband transactions.
