Subject: vc4: Don't try to use color load/stores to do depth/stencil blits.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cff2e08c4cb87b7c2e19100e24c336e50b9839cc;p=mesa.git

vc4: Don't try to use color load/stores to do depth/stencil blits.

Fixes regressions in fbo-generatemipmap-formats on depth/stencil (which
does blits to work around baselevel/lastlevel).
