I finished bisecting (again). The result looks like this: git bisect bad c0c979eebc076b95cc8d18a013ce2968fe6311ad is the first bad commit commit c0c979eebc076b95cc8d18a013ce2968fe6311ad Author: Jerome Glisse <jglisse@redhat.com> Date: Mon Jan 30 17:22:13 2012 -0500 r600g: add support for common surface allocator for tiling v13 Tiled surface have all kind of alignment constraint that needs to be met. Instead of having all this code duplicated btw ddx and mesa use common code in libdrm_radeon this also ensure that both ddx and mesa compute those alignment in the same way. v2 fix evergreen v3 fix compressed texture and workaround cube texture issue by disabling 2D array mode for cubemap (need to check if r7xx and newer are also affected by the issue) v4 fix texture array v5 fix evergreen and newer, split surface values computation from mipmap tree generation so that we can get them directly from the ddx v6 final fix to evergreen tile split value v7 fix mipmap offset to avoid to use random value, use color view depth view to address different layer as hardware is doing some magic rotation depending on the layer v8 fix COLOR_VIEW on r6xx for linear array mode, use COLOR_VIEW on evergreen, align bytes per pixel to a multiple of a dword v9 fix handling of stencil on evergreen, half fix for compressed texture v10 fix evergreen compressed texture proper support for stencil tile split. Fix stencil issue when array mode was clear by the kernel, always program stencil bo. On evergreen depth buffer bo need to be big enough to hold depth buffer + stencil buffer as even with stencil disabled things get written there. v11 rebase on top of mesa, fix pitch issue with 1d surface on evergreen, old ddx overestimate those. Fix linear case when pitch*height < 64. Fix r300g. v12 Fix linear case when pitch*height < 64 for old path, adapt to libdrm API change v13 add libdrm check Signed-off-by: Jerome Glisse <jglisse@redhat.com> :100644 100644 af1e914f35aebf24c4824e93804c9f9088be7333 b2b1ab8f41a131089b84325fef962f7d4d79bb8d M configure.ac :040000 040000 facdf8849a029e15e166ffcf17c2db2d57ee9530 fa9bf703af2882d35c8d7e83022c8b80d43ae390 M src
