39 * This is the table of support for surface (texture, renderbuffer, and vertex
40 * buffer, but not depthbuffer) formats across the various hardware generations.
41 *
42 * The table is formatted to match the documentation, except that the docs have
43 * this ridiculous mapping of Y[*+~^#&] for "supported on DevWhatever". To put
44 * it in our table, here's the mapping:
45 *
46 * Y*: 45
47 * Y+: 45 (g45/gm45)
48 * Y~: 50 (gen5)
49 * Y^: 60 (gen6)
50 * Y#: 70 (gen7)
51 *
52 * The abbreviations in the header below are:
53 * smpl - Sampling Engine
54 * filt - Sampling Engine Filtering
55 * shad - Sampling Engine Shadow Map
56 * CK - Sampling Engine Chroma Key
57 * RT - Render Target
58 * AB - Alpha Blend Render Target
59 * VB - Input Vertex Buffer
60 * SO - Steamed Output Vertex Buffers (transform feedback)
61 * color - Color Processing
62 * ccs_e - Lossless Compression Support (gen9+ only)
63 * sf - Surface Format
64 *
65 * See page 88 of the Sandybridge PRM VOL4_Part1 PDF.
66 *
67 * As of Ivybridge, the columns are no longer in that table and the
68 * information can be found spread across:
69 *
70 * - VOL2_Part1 section 2.5.11 Format Conversion (vertex fetch).
71 * - VOL4_Part1 section 2.12.2.1.2 Sampler Output Channel Mapping.
72 * - VOL4_Part1 section 3.9.11 Render Target Write.
73 * - Render Target Surface Types [SKL+]
