7 /* Resource binding slots and sampler states (each described with 8 or
8  * 4 dwords) are stored in lists in memory which is accessed by shaders
9  * using scalar load instructions.
10  *
11  * This file is responsible for managing such lists. It keeps a copy of all
12  * descriptors in CPU memory and re-uploads a whole list if some slots have
13  * been changed.
14  *
15  * This code is also responsible for updating shader pointers to those lists.
16  *
17  * Note that CP DMA can't be used for updating the lists, because a GPU hang
18  * could leave the list in a mid-IB state and the next IB would get wrong
19  * descriptors and the whole context would be unusable at that point.
20  * (Note: The register shadowing can't be used due to the same reason)
21  *
22  * Also, uploading descriptors to newly allocated memory doesn't require
23  * a KCACHE flush.
24  *
25  *
26  * Possible scenarios for one 16 dword image+sampler slot:
27  *
28  *       | Image        | w/ FMASK   | Buffer       | NULL
29  * [ 0: 3] Image[0:3]   | Image[0:3] | Null[0:3]    | Null[0:3]
30  * [ 4: 7] Image[4:7]   | Image[4:7] | Buffer[0:3]  | 0
31  * [ 8:11] Null[0:3]    | Fmask[0:3] | Null[0:3]    | Null[0:3]
32  * [12:15] Sampler[0:3] | Fmask[4:7] | Sampler[0:3] | Sampler[0:3]
33  *
34  * FMASK implies MSAA, therefore no sampler state.
35  * Sampler states are never unbound except when FMASK is bound.
