<div>
<pre>I have a NVidia GeForce 7600GT with the latest git nouveau driver (Gallium 0.4
on NV4B) and kernel 3.7.9.
I found the following problem: calling the function glVertexAttribPointer(idx,
GL_UNSIGNED_BYTE, GL_FALSE,...) does not work, that is the previous attrib
pointer remains, and the nouveau driver outputs in the dmesg:
[ 2052.630628] nouveau [ PGRAPH][0000:01:00.0] ERROR nsource: DATA_ERROR
nstatus: BAD_ARGUMENT
[ 2052.630644] nouveau E[ PGRAPH][0000:01:00.0] ch 3 [0x000dd000] subc 7 class
0x4097 mthd 0x1744 data 0x00001417
But glGetError() returns nothing unusual.
If I change the parameter from GL_UNSIGNED_BYTE to any other type (GL_BYTE,
GL_UNSIGNED_SHORT, GL_SHORT...) then it works as expected.
If I change the "normalized" parameter to GL_TRUE, it also works fine, even
with type GL_UNSIGNED_BYTE.
The software renderer does not have this problem. That and the kernel messages
suggest that it is a nouveau issue.</pre>
