/* The vertex attributes start at a URB row-aligned offset after
* the 8-20 dword vertex header, and continue for a URB row-aligned
* length. nr_regs determines the urb_read_length from the start
* of the header to the end of the vertex data.
/* nr_regs is the number of registers filled by reading data from the VUE.
* This program accesses the entire VUE, so nr_regs needs to be the size of
* the VUE (measured in pairs, since two slots are stored in each
* register).
