25 /* Resource binding slots and sampler states (each described with 8 or
26 * 4 dwords) are stored in lists in memory which is accessed by shaders
27 * using scalar load instructions.
29 * This file is responsible for managing such lists. It keeps a copy of all
30 * descriptors in CPU memory and re-uploads a whole list if some slots have
33 * This code is also reponsible for updating shader pointers to those lists.
35 * Note that CP DMA can't be used for updating the lists, because a GPU hang
36 * could leave the list in a mid-IB state and the next IB would get wrong
37 * descriptors and the whole context would be unusable at that point.
38 * (Note: The register shadowing can't be used due to the same reason)
40 * Also, uploading descriptors to newly allocated memory doesn't require
44 * Possible scenarios for one 16 dword image+sampler slot:
46 * | Image | w/ FMASK | Buffer | NULL
47 * [ 0: 3] Image[0:3] | Image[0:3] | Null[0:3] | Null[0:3]
48 * [ 4: 7] Image[4:7] | Image[4:7] | Buffer[0:3] | 0
49 * [ 8:11] Null[0:3] | Fmask[0:3] | Null[0:3] | Null[0:3]
50 * [12:15] Sampler[0:3] | Fmask[4:7] | Sampler[0:3] | Sampler[0:3]
52 * FMASK implies MSAA, therefore no sampler state.
53 * Sampler states are never unbound except when FMASK is bound.

71 * For images, all fields must be zero except for the swizzle, which

73 * any valid type (e.g. 1D). If the texture type isn't set, the hw hangs.
