* mesa/texcompress: correct mapping of S3TC formats in conversion functionNanley Chery2015-08-311-2/+2
| | | | | | | | | MESA_FORMAT_RGBA_DXT5 should actually be reserved for GL_RGBA[4]_DXT5_S3TC. Also, Gallium and other dri drivers (radeon and nouveau) follow this mapping scheme. Reviewed-by: Chad Versace <[email protected]> Signed-off-by: Nanley Chery <[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.
