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