With this manager, the drivers don't have to deal with user buffers when they are bound as vertex buffers. They only get real hardware buffers. </blockquote> Please do *not* take away my user buffers and put user vertex arrays at the mercy of a state tracker ! In the DrawArrays case I usually use util/translate and interleave them letting it write directly into my command buffer for immediate mode vertex data submission. Thanks. <blockquote cite="mid:AANLkTi=OWdCo2_Ow7Vnsteo97OAzYh1TaeP_hz3OVcYw@mail.gmail.com" type="cite"> -- So this all is my current plan to simplify hardware drivers a bit and add some nice optimizations. Another option would be to move the new vertex buffer manager or something equivalent to the state tracker and remove user buffers from the Gallium interface, but that would be additional work with uncertain performance implications, so I decided not to take this path (for now).
