From: Dave Airlie Date: Wed, 16 Aug 2017 05:20:29 +0000 (+0100) Subject: radv: handle GFX9 1D textures X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1bcb953e16600e0d9329b678a6eacee98d326547;p=mesa.git radv: handle GFX9 1D textures As GFX9 can't handle 1D depth textures, radeonsi and apparantly pro just update all 1D textures to 2D, and work around it. This ports the workarounds from radeonsi.
