From 6d751065cca931798f2ad9e68f936d3d41886e4f Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Wed, 20 Aug 2014 01:34:37 +0200 Subject: r600g: use HTILE allocator from SI MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It's almost the same. This enables tiling for HTILE. It also enables Hyper-Z for other texture targets (1D, 1D_ARRAY, 2D_ARRAY, CUBE, CUBE_ARRAY, 3D, RECT). 2D array depth textures are tested by Unigine Sanctuary and my new piglit test.
