<pre>dEQP-GLES3.functional.negative_api.texture.generatemipmap currently fails.
genmipmap.c has a _mesa_is_valid_generate_texture_mipmap_internalformat
function that implements some rules. It appears that there is no text in the
OpenGL specifications to justify this, but it was discussed in a Khronos
internal bug:
<a href="https://cvs.khronos.org/bugzilla/show_bug.cgi?id=9471">https://cvs.khronos.org/bugzilla/show_bug.cgi?id=9471</a>
However, ES 3.0 has well defined rules:
"If the levelbase array was not specified with an unsized internal format from
table 3.3 or a sized internal format that is both color-renderable and
texture-filterable according to table 3.13, an INVALID_OPERATION error is
generated."
These rules need to be implemented (replacing the desktop GL rules), and would
fix the test.</pre>
