drm/radeon/kms: fix the colorbuffer CS checker for r300-r500
This commit fixes bogus CS rejection if it contains a sequence of the following operations: - Set the color buffer 0. track->cb[i].robj becomes non-NULL. - Render. - Set a larger zbuffer than the previously-set color buffer. - Set a larger scissor area as well. - Set the color channel mask to 0 to do depth-only rendering. - Render. --> rejected, because track->cb[i].robj remained non-NULL, therefore the conditional checking for the color channel mask and friends is not performed, and the larger scissor area causes the rejection. This fixes bugs: - https://bugs.freedesktop.org/show_bug.cgi?id=29762 - https://bugs.freedesktop.org/show_bug.cgi?id=28869 And maybe some others which seem to look the same. If possible, this commit should go to stable as well. Signed-off-by: Marek Olšák <maraeo@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
