mesa: Generate invalid operation in glGenerateMipMap for integer textures
Khronos has reached a conclusion and disallowed following texture formats in
glGenerateMipMap():
(a) ASTC textures
(b) integer internal formats (e.g., RGBA8UI, RG16I)
(c) textures with stencil formats (e.g., STENCIL_INDEX8)
(d) textures with packed depth/stencil formats (e.g, DEPTH24_STENCIL8)
https://cvs.khronos.org/bugzilla/show_bug.cgi?id=9471
Note: This is a candidate for stable branches.
