420  *  - bits 0-15: DMA_A instance
421  *  - bits 16-31: DMA_B instance
422  *
423  * NV05 will set/unset the relevant valid bits when you poke the relevant
424  * object-binding methods with object of the proper type, or with the NULL
425  * type. It'll only allow rendering using the grobj if all needed objects
426  * are bound. The needed set of objects depends on selected operation: for
427  * example rop object is needed by ROP_AND, but not by SRCCOPY_AND.
428  *
429  * NV04 doesn't have these methods implemented at all, and doesn't have the
430  * relevant bits in grobj. Instead, it'll allow rendering whenever bit 24
431  * is set. So we have to emulate them in software, internally keeping the
432  * same bits as NV05 does. Since grobjs are aligned to 16 bytes on nv04,
433  * but the last word isn't actually used for anything, we abuse it for this
434  * purpose.
435  *
436  * Actually, NV05 can optionally check bit 24 too, but we disable this since
437  * there's no use for it.
438  *
439  * For unknown reasons, NV04 implements surf3d binding in hardware as an
440  * exception. Also for unknown reasons, NV04 doesn't implement the clipping
441  * methods on the surf3d object, so we have to emulate them too.
