Subject: r300g: do not advertise color_buffer_float on r300 and r400
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=72239d16cd08113e994ea3508f91193c682b0930;p=mesa.git

r300g: do not advertise color_buffer_float on r300 and r400

It seems they can't do unclamped vertex colors. Tested on RV350.
