Subject: lima: decode depth/stencil write bits in RSW
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0c41937440276498b76c30657bc8d884ed8220db;p=mesa.git

lima: decode depth/stencil write bits in RSW

Now that we know the bits that are responsible for enabling depth/stencil
writes in shader we can decode them properly.
