/*
* 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.
