Subject: panfrost: Z/S can't be tiled
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=aea3f0ac1d1e281b5d2f2100acad87810ed309c0;p=mesa.git

panfrost: Z/S can't be tiled

As far as we know, Utgard-style tiling only works for color render
targets, not depth/stencil, so ensure we don't try to tile it (rather
than compress or plain old linear) and drive ourselves into a corner.
