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.
I've sent review comments for a bunch of the patches. The only thing
that I'm really concerned about is the sRGB issue. Decoding compressed
sRGB textures to uncompressed RGB is probably not right. I believe that
those should all be decoded to uncompressed sRGB. Other than changing
around where some enums are in switch statements, I think that will
actually simplify the code... no need to do software sRGB decoding. :)
