371 * Software methods, why they are needed, and how they all work:
372 *
373 * NV04 and NV05 keep most of the state in PGRAPH context itself, but some
374 * 2d engine settings are kept inside the grobjs themselves. The grobjs are
375 * 3 words long on both. grobj format on NV04 is:
376 *
377 * word 0:
378 * - bits 0-7: class
379 * - bit 12: color key active
380 * - bit 13: clip rect active
381 * - bit 14: if set, destination surface is swizzled and taken from buffer 5
382 * [set by NV04_SWIZZLED_SURFACE], otherwise it's linear and taken
383 * from buffer 0 [set by NV04_CONTEXT_SURFACES_2D or
384 * NV03_CONTEXT_SURFACE_DST].
385 * - bits 15-17: 2d operation [aka patch config]
386 * - bit 24: patch valid [enables rendering using this object]
387 * - bit 25: surf3d valid [for tex_tri and multitex_tri only]
388 * word 1:
389 * - bits 0-1: mono format
390 * - bits 8-13: color format
391 * - bits 16-31: DMA_NOTIFY instance
392 * word 2:
393 * - bits 0-15: DMA_A instance
394 * - bits 16-31: DMA_B instance
395 *
396 * On NV05 it's:
397 *
398 * word 0:
399 * - bits 0-7: class
400 * - bit 12: color key active
401 * - bit 13: clip rect active
402 * - bit 14: if set, destination surface is swizzled and taken from buffer 5
403 * [set by NV04_SWIZZLED_SURFACE], otherwise it's linear and taken
404 * from buffer 0 [set by NV04_CONTEXT_SURFACES_2D or
405 * NV03_CONTEXT_SURFACE_DST].
406 * - bits 15-17: 2d operation [aka patch config]
407 * - bits 20-22: dither mode
408 * - bit 24: patch valid [enables rendering using this object]
409 * - bit 25: surface_dst/surface_color/surf2d/surf3d valid
410 * - bit 26: surface_src/surface_zeta valid
411 * - bit 27: pattern valid
412 * - bit 28: rop valid
413 * - bit 29: beta1 valid
414 * - bit 30: beta4 valid
415 * word 1:
416 * - bits 0-1: mono format
417 * - bits 8-13: color format
418 * - bits 16-31: DMA_NOTIFY instance
419 * word 2:
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.
