Subject: r300g: allow separate depth and stencil clear
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5fc83101fbb9b7dd0d7f0b91a9b1c1c1bc0250b6;p=mesa.git

r300g: allow separate depth and stencil clear

The handling of the CAP is broken in st/mesa anyway. Let's just kill it.

This commit pretty much enables fast Z clear for FBOs with Z24S8.
The driver falls back to clearing with a quad if the fast clear cannot be
used. It can still do fast color clear, for example.
