| * 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 |
| * |
| * 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. |
