X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fe635d51ff95def49f5941ebf6ca5f1dbbef3d30;p=mesa.git i965: For fast color clears, only check the color of live channels. When deciding if a clear color is suitable for fast clear, take into account if a color channel is active in the buffer format.
