Nouveau - Apr 2016 - "unknown fragment shader param 17" error on NV46 when running glxgears

Hi,

While trying to reproduce:
https://bugzilla.redhat.com/show_bug.cgi?id=1325667

I also gave glxgears a quick test with mesa master, this
resulted in the following errors being printed to the
terminal from which glxgears was started :

unknown fragment shader param 17
unknown fragment shader param 17
unknown fragment shader param 17
unknown fragment shader param 17
unknown fragment shader param 17

I would like to fix these, any hints where I need to look ?

Regards,

Hans

It seems like that PIPE_SHADER_CAP_INTEGERS for frag shaders is missing 
in nv30_screen_get_shader_param(). This won't fix your issue but this 
will silence this debug message though.
