[Mesa-dev] [PATCH 00/27] intel: Add ETC2 compressed textures support

[Anuj Phogat]

This series lives on my etc2-v9 branch (https://github.com/aphogat/mesa).

This series enables 8 out of 10 ETC2 texture formats for all Intel
hardware by simply decoding the ETC2 data into RGBX data at the time
of glCompressedTexImage2D. These patches can be tested using piglit
test case i have added for etc2 textures. Patches for the test are under
review on piglit mailing list.

I'll soon post the patches for remaining 2 etc2 formats as well.
