Subject: blorp: Use FullSurfaceDepthandStencilClear for blorp_hiz_op
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bacae7221bf9b82520175fd7c8d1f5089096159d;p=mesa.git

blorp: Use FullSurfaceDepthandStencilClear for blorp_hiz_op

The blorp_hiz_op entrypoint always acts on a full subresource of a HiZ
buffer so we can just set the flag unconditionally.
