Description Ian Romanick 2008-12-19 13:14:21 UTC

Compressed texture formats are supposed to be supported by both automatic mipmap generation mechanisms.  However, there does not seem to be any code in Mesa to handle it.

Mass version move, cvs -> git

Ian,

this appears to be fixed. Can I close or am I missing something?

Comment 3 Ian Romanick 2011-03-01 17:53:48 UTC

That's a good question.  Do we have a test case?  I recall that I found the bug by inspection, but I never made a test case for it.  Until you pinged me about it, I had completely forgotten.

fbo-generatemipmap-formats passes for S3TC textures.

I guess _automatic_ mipmap generation is SGIS_generate_mipmap. I tried mipmap_limits, which uses GL_GENERATE_MIPMAP, with the internal format changed to RGB_DXT1 and RGBA_DXT5 and both worked.

Works for me. Closing.
