Subject: radeon: for tiling you really need to use GET/PUT VALUE not PTR.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9b17f041d12cfe9a34df43da93fc16e275a5c751;p=mesa.git

radeon: for tiling you really need to use GET/PUT VALUE not PTR.

since the surfaces aren't linear you can't just use GET_PTR
