103 * This is the table of support for surface (texture, renderbuffer, and vertex
104 * buffer, but not depthbuffer) formats across the various hardware generations.
106 * The table is formatted to match the documentation, except that the docs have
107 * this ridiculous mapping of Y[*+~^#&] for "supported on DevWhatever". To put
108 * it in our table, here's the mapping:
116 * The abbreviations in the header below are:
117 * smpl - Sampling Engine
118 * filt - Sampling Engine Filtering
119 * shad - Sampling Engine Shadow Map
120 * CK - Sampling Engine Chroma Key
122 * AB - Alpha Blend Render Target
123 * VB - Input Vertex Buffer
124 * SO - Steamed Output Vertex Buffers (transform feedback)
125 * color - Color Processing
127 * See page 88 of the Sandybridge PRM VOL4_Part1 PDF.
129 * As of Ivybridge, the columns are no longer in that table and the
130 * information can be found spread across:
132 * - VOL2_Part1 section 2.5.11 Format Conversion (vertex fetch).
133 * - VOL4_Part1 section 2.12.2.1.2 Sampler Output Channel Mapping.
134 * - VOL4_Part1 section 3.9.11 Render Target Write.
