 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.
