* mesa: Add texel fetch functions for BPTC-compressed texturesNeil Roberts2014-08-121-0/+6
| | | | | | | | | | Adds functions to fetch from any of the four BPTC-compressed formats. v2: Set the alpha component to 1.0 when fetching from the half-float formats instead of leaving it uninitialised. Don't linearize the alpha component when fetching from sRGB. Reviewed-by: Ian Romanick <[email protected]>
* mesa: Add the format enums for BPTC-compressed imagesNeil Roberts2014-08-121-0/+24
| | | | | | | | | | | | | | | | | | This adds the following four Mesa image format enums which correspond to the four BPTC compressed texture formats: MESA_FORMAT_BPTC_RGBA_UNORM MESA_FORMAT_BPTC_SRGB_ALPHA_UNORM MESA_FORMAT_BPTC_RGB_SIGNED_FLOAT MESA_FORMAT_BPTC_RGB_UNSIGNED_FLOAT It also updates the format information functions to handle these and the corresponding GL enums. v2: Also modify _mesa_get_format_color_encoding, _mesa_get_srgb_format_linear and _mesa_get_uncompressed_format Reviewed-by: Ian Romanick <[email protected]>

* mesa: Add COMPRESSED_RGBA_S3TC_DXT1_EXT to COMPRESSED_TEXTURE_FORMATS for GLESIan Romanick2014-01-151-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ES and desktop GL specs diverge here. Yay! In desktop OpenGL, the driver can perform online compression of uncompressed texture data. GL_NUM_COMPRESSED_TEXTURE_FORMATS and GL_COMPRESSED_TEXTURE_FORMATS give the application a list of formats that it could ask the driver to compress with some expectation of quality. The GL_ARB_texture_compression spec calls this "suitable for general-purpose usage." As noted above, this means GL_COMPRESSED_RGBA_S3TC_DXT1_EXT is not included in the list. In OpenGL ES, the driver never performs compression. GL_NUM_COMPRESSED_TEXTURE_FORMATS and GL_COMPRESSED_TEXTURE_FORMATS give the application a list of formats that the driver can receive from the application. It is the *complete* list of formats. The GL_EXT_texture_compression_s3tc spec says: "New State for OpenGL ES 2.0.25 and 3.0.2 Specifications The queries for NUM_COMPRESSED_TEXTURE_FORMATS and COMPRESSED_TEXTURE_FORMATS include COMPRESSED_RGB_S3TC_DXT1_EXT, COMPRESSED_RGBA_S3TC_DXT1_EXT, COMPRESSED_RGBA_S3TC_DXT3_EXT, and COMPRESSED_RGBA_S3TC_DXT5_EXT." Note that the addition is only to the OpenGL ES specification!

| | | | | | | | | | | | | | | | | | | | | | | | | Data in GL_COMPRESSED_SIGNED_R11_EAC format is decoded and stored in MESA_FORMAT_SIGNED_R16. v2: 16 bit signed data is converted to 16 bit unsigned data by adding 2 ^ 15 and stored in an unsigned texture format. v3: 1. Handle a corner case when base code word value is -128. As per OpenGL ES 3.0 specification -128 is not an allowed value and should be truncated to -127. 2. Converting a decoded 16 bit signed data to 16 bit unsigned data by adding 2 ^ 15 gives us an output which matches the decompressed image (.ppm) generated by ericsson's etcpack tool. ericsson is also doing this conversion in their tool because .ppm image files don't support signed data. But gles 3.0 specification doesn't suggest this conversion. We need to keep the decoded data in signed format. Both signed format tests in gles3 conformance pass with these changes.

| | | | | | | | | | | | | | | | | The encoding/decoding algorithms are shared with RGTC. Thanks to some magic with the base format, the RGTC texstore functions work for LATC too. swrast passes the related piglit tests besides two things: - The alpha channel is wrong (it's always 1), however the incorrect alpha channel makes some other tests fail too, so I guess it's unrelated to LATC. - Signed LATC fetches aren't correct yet (signed values are clamped to [0,1]), however RGTC has the same problem. Further testing (with other of my patches) shows that hardware drivers and softpipe work. BTW, ETQW uses this extension.
