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