This series lives on my gles3-etc2-v3 branch (https://github.com/aphogat/mesa).
It enables ETC2 texture formats for all Intel hardware. ETC2 texture
data is decoded into a suitable uncompressed mesa format at the time
of glCompressedTexImage2D. These patches can be tested using piglit
test case i have posted for etc2 textures. Patches for the test are
under review on piglit mailing list.
Changes in V2:
- Now decodes SRGB ETC2 formats to MESA_FORMAT_SARGB.
- Fixed an issue with signed-{r, rg}11 decoding. Decoded 16 bit signed
data is now converted to 16 bit unsigned data by adding 2 ^ 15 and
stored in an unsigned mesa texture format. This makes piglit etc2
test case pass for these formats.
- Added entries to texfetch_funcs[] array. ETC2 piglit test passes on
swrast.
- Squashed together all patches to enable etc2 formats on intel h/w.
- Now uses nonlinear_to_linear() function to convert from SRGB to
linear RGB.
Changes in V3:
- Squash all "mesa: Add new ETC2 format" patches together.
- nonlinear_to_linear() function is made non static inline.
- Correctly increment variable 'n' in _mesa_get_compressed_formats.
- Remove unnecessary casts in _mesa_fetch_texel_* functions in
texcompress_etc.c.
- Use uint8_t uniformly across texcompress_etc.c.
- Fix indentation issues.
