Looks tiling related, + at the last frame rendered has tiling corruption over the complete frame. + +- Kills the chip in 3D_PRIMITIVE LINELIST with mesa-demos/fbotexture in + wireframe mode. + +- Tiling is funny: If unlucky, it renders/samples all black. No clue yet what's + going on. Seems to depend on tiny details like whethever the sampler + relocation is fenced/unfenced (broken _with_ fenced reloc using tiling bits!). + +- Y-tiling is even more fun. i915c doesn't use it, maybe there's a reason? + Texture sampling from Y-tiled buffers seems to work, though (save above + problems). + +- Need to validate buffers before usage.
