From f30df2fad0c901e74ac9a52a488a54c69a373a41 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Thu, 21 Oct 2010 13:55:40 +1000 Subject: drm/radeon/r600: fix tiling issues in CS checker. The CS checker had some incorrect alignment requirements for 2D surfaces, this made rendering to mipmap levels that were 2D broken. Also the CB height was being worked out from the BO size, this doesn't work at all when rendering mipmap levels, instead we work out what height userspace wanted from slice max and use that to check it fits inside the BO, however the DDX send the wrong slice max for an unaligned buffer so we have to workaround for that even though its a userspace bug.
