+/*
+ * This file implements the vmwgfx context binding manager,
+ * The sole reason for having to use this code is that vmware guest
+ * backed contexts can be swapped out to their backing mobs by the device
+ * at any time, also swapped in at any time. At swapin time, the device
+ * validates the context bindings to make sure they point to valid resources.
+ * It's this outside-of-drawcall validation (that can happen at any time),
+ * that makes this code necessary.
+ *
+ * We therefore need to kill any context bindings pointing to a resource
+ * when the resource is swapped out. Furthermore, if the vmwgfx driver has
+ * swapped out the context we can't swap it in again to kill bindings because
+ * of backing mob reservation lockdep violations, so as part of
+ * context swapout, also kill all bindings of a context, so that they are
+ * already killed if a resource to which a binding points
+ * needs to be swapped out.
+ *
+ * Note that a resource can be pointed to by bindings from multiple contexts,
+ * Therefore we can't easily protect this data by a per context mutex
+ * (unless we use deadlock-safe WW mutexes). So we use a global binding_mutex
+ * to protect all binding manager data.
+ *
+ * Finally, any association between a context and a global resource
+ * (surface, shader or even DX query) is conceptually a context binding that
+ * needs to be tracked by this code.
