63 * This is the table of support for surface (texture, renderbuffer, and vertex
64 * buffer, but not depthbuffer) formats across the various hardware generations.
65 *
66 * The table is formatted to match the documentation, except that the docs have
67 * this ridiculous mapping of Y[*+~^#&] for "supported on DevWhatever". To put
68 * it in our table, here's the mapping:
69 *
70 * Y*: 45
71 * Y+: 45 (g45/gm45)
72 * Y~: 50 (gfx5)
73 * Y^: 60 (gfx6)
74 * Y#: 70 (gfx7)
75 *
76 * The abbreviations in the header below are:
77 * smpl - Sampling Engine
78 * filt - Sampling Engine Filtering
79 * shad - Sampling Engine Shadow Map
80 * CK - Sampling Engine Chroma Key
81 * RT - Render Target
82 * AB - Alpha Blend Render Target
83 * VB - Input Vertex Buffer
84 * SO - Steamed Output Vertex Buffers (transform feedback)
85 * color - Color Processing
86 * TW - Typed Write
87 * TR - Typed Read
88 * ccs_e - Lossless Compression Support (gfx9+ only)
89 * sf - Surface Format
90 *
91 * See page 88 of the Sandybridge PRM VOL4_Part1 PDF.
92 *
93 * As of Ivybridge, the columns are no longer in that table and the
94 * information can be found spread across:
95 *
96 * - VOL2_Part1 section 2.5.11 Format Conversion (vertex fetch).
97 * - VOL4_Part1 section 2.12.2.1.2 Sampler Output Channel Mapping.
98 * - VOL4_Part1 section 3.9.11 Render Target Write.
99 * - Render Target Surface Types [SKL+]
