27 | /* |
||
28 | * This file implements the vmwgfx context binding manager, |
||
29 | * The sole reason for having to use this code is that vmware guest |
||
30 | * backed contexts can be swapped out to their backing mobs by the device |
||
31 | * at any time, also swapped in at any time. At swapin time, the device |
||
32 | * validates the context bindings to make sure they point to valid resources. |
||
33 | * It's this outside-of-drawcall validation (that can happen at any time), |
||
34 | * that makes this code necessary. |
||
35 | * |
||
36 | * We therefore need to kill any context bindings pointing to a resource |
||
37 | * when the resource is swapped out. Furthermore, if the vmwgfx driver has |
||
38 | * swapped out the context we can't swap it in again to kill bindings because |
||
39 | * of backing mob reservation lockdep violations, so as part of |
||
40 | * context swapout, also kill all bindings of a context, so that they are |
||
41 | * already killed if a resource to which a binding points |
||
42 | * needs to be swapped out. |
||
43 | * |
||
44 | * Note that a resource can be pointed to by bindings from multiple contexts, |
||
45 | * Therefore we can't easily protect this data by a per context mutex |
||
46 | * (unless we use deadlock-safe WW mutexes). So we use a global binding_mutex |
||
47 | * to protect all binding manager data. |
||
48 | * |
||
49 | * Finally, any association between a context and a global resource |
||
50 | * (surface, shader or even DX query) is conceptually a context binding that |
||
51 | * needs to be tracked by this code. |
