|
* 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
|
|
|
|
* ccs_e - Lossless Compression Support (gen9+ only)
|
|
|
|
* 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).
