Hello,
Here is a patch that adds PIPE_CAP_BLEND_EQUATION_SEPARATE, for
hardware that does not have this capability. I added the diff for
nouveau gallium backend only, as I don't know anything about other
vendor hardware.
The only thing I am not sure is the patch to
src/gallium/state_trackers/dri/dri_extensions.c I simply remove it
from the list, but should I keep the #define need_xxxx for this
extension?.
