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. + */ + +/** + * drm_dp_mst_get_mstb_malloc() - Increment the malloc refcount of a branch + * device + * @mstb: The &struct drm_dp_mst_branch to increment the malloc refcount of + * + * Increments &drm_dp_mst_branch.malloc_kref.
