52 * This is the table of support for surface (texture, renderbuffer, and vertex
53 * buffer, but not depthbuffer) formats across the various hardware generations.
54 *
55 * The table is formatted to match the documentation, except that the docs have
56 * this ridiculous mapping of Y[*+~^#&] for "supported on DevWhatever". To put
57 * it in our table, here's the mapping:
58 *
59 * Y*: 45
60 * Y+: 45 (g45/gm45)
61 * Y~: 50 (gen5)
62 * Y^: 60 (gen6)
63 * Y#: 70 (gen7)
64 *
65 * The abbreviations in the header below are:
66 * smpl - Sampling Engine
67 * filt - Sampling Engine Filtering
68 * shad - Sampling Engine Shadow Map
69 * CK - Sampling Engine Chroma Key
70 * RT - Render Target
71 * AB - Alpha Blend Render Target
72 * VB - Input Vertex Buffer
73 * SO - Steamed Output Vertex Buffers (transform feedback)
74 * color - Color Processing
75 * ccs_e - Lossless Compression Support (gen9+ only)
76 * sf - Surface Format
77 *
78 * See page 88 of the Sandybridge PRM VOL4_Part1 PDF.
79 *
80 * As of Ivybridge, the columns are no longer in that table and the
81 * information can be found spread across:
82 *
83 * - VOL2_Part1 section 2.5.11 Format Conversion (vertex fetch).
84 * - VOL4_Part1 section 2.12.2.1.2 Sampler Output Channel Mapping.
85 * - VOL4_Part1 section 3.9.11 Render Target Write.
86 * - Render Target Surface Types [SKL+]
