I got past first triangle (in simulation) on V3D 4.1, and got texturing working as well. The big feature was to enable multithreaded fragment shaders, which I first did on V3D 3.3. Once I had that, it was easy to port over to 4.1 and get my first fragment shader running. Other tasks this week:

• Ported the command list and state dumping code to 4.1
• Added support for V3D 4.1’s arbitrary register writes in varying loads and texturing
• Ported the other state emits besides the draw calls
• Enabled texturing on V3D 4.1 (border color swizzling still broken)
• Fixed infinite loops in shaders without all the channels active
• Fixed gl_FragCoord pixel center setup
• Fixed overflows of the tile state array
• Started writing tools for debugging GPU hangs

This is all pushed to Mesa master now.
