I think this is actually a bug in the piglit test.
The glTexSubImage call in question can generate either GL_INVALID_ENUM or
GL_INVALID_OPERATION depending on what order glTexSubImage() does its parameter
error
checking:
>From the spec:
INVALID_ENUM is generated by DrawPixels, TexImage* and
SubTexImage* if <format> is one of the integer component formats
described in table 3.6 and <type> is FLOAT.
and:
INVALID_OPERATION is generated by TexImage* and SubTexImage* if
the texture internalformat is an integer format as described in
table 3.16 and <format> is not one of the integer component
formats described in table 3.6, or if the internalformat is not an
integer format and <format> is an integer format.
I can fix the piglit test, but after reviewing Mesa it looks like we're missing
the later error check for glTexSubImage. I'll work on that too...
