* mesa: Fix texture compression on big-endian systemsUlrich Weigand2015-09-171-2/+4
| | | | | | | | | | | | | | | | | | | | | | | Various pieces of code to create compressed textures will first generate an uncompressed RGBA texture into a temporary buffer, and then read from that buffer while creating the final compressed texture in the requested format. The code reading from the temporary buffer assumes the buffer is formatted as an array of bytes in RGBA order. However, the buffer is filled using a _mesa_texstore call with MESA_FORMAT_R8G8B8A8_UNORM format -- this is defined as an array of *integers* holding the RGBA values in packed format (least-significant to most-significant). This means incorrect bytes are accessed on big-endian systems. This patch fixes this by using the MESA_FORMAT_A8B8G8R8_UNORM format instead on big-endian systems when filling the buffer. This fixes about 100 piglit test case failures on s390x for me.

* mesa: Remove _mesa_make_temp_float_imageIago Toral Quiroga2015-01-121-14/+31
| | | | | | | | | | Now that we have _mesa_format_convert we don't need this. This was only used to create temporary RGBA float images in the process of storing some compressed formats. These can call _mesa_texstore with a RGBA/float dst to achieve the same goal. Reviewed-by: Jason Ekstrand <jason.ekstrand@intel.com>

| | | | | | | | | | | | Now that we have _mesa_format_convert we don't need this. texstore_rgba will use the GL_COLOR_INDEX to RGBA conversion helpers instead and compressed formats that used _mesa_make_temp_ubyte_image to create an ubyte RGBA temporary image can call _mesa_texstore with a RGBA/ubyte dst to achieve the same goal.

* mesa: add EXT_texture_compression_latcMarek Olšák2011-03-081-4/+64
| | | | | | | | | | | | | | | | | 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.
