66 * Mask/shift definitions for TIO:CA registers. The convention here is
67 * to mainly use the names as they appear in the "TIO AEGIS Programmers'
68 * Reference" with a CA_ prefix added. Some exceptions were made to fix
69 * duplicate field names or to generalize fields that are common to
70 * different registers (ca_debug_mux_core_sel and ca_debug_mux_pci_sel for
71 * example).
72 *
73 * Fields consisting of a single bit have a single #define have a single
74 * macro declaration to mask the bit. Fields consisting of multiple bits
75 * have two declarations: one to mask the proper bits in a register, and
76 * a second with the suffix "_SHFT" to identify how far the mask needs to
77 * be shifted right to get its base value.

488 * DMA space
489 *
490 * The CA aperature (ie. bus address range) mapped by the GART is segmented into
491 * two parts. The lower portion of the aperature is used for mapping 32 bit
492 * PCI addresses which are managed by the dma interfaces in this file. The
493 * upper poprtion of the aperature is used for mapping 48 bit AGP addresses.
494 * The AGP portion of the aperature is managed by the agpgart_be.c driver
495 * in drivers/linux/agp. There are ca-specific hooks in that driver to
496 * manipulate the gart, but management of the AGP portion of the aperature
497 * is the responsibility of that driver.
498 *
499 * CA allows three main types of DMA mapping:
500 *
501 * PCI 64-bit Managed by this driver
502 * PCI 32-bit Managed by this driver
503 * AGP 48-bit Managed by hooks in the /dev/agpgart driver
504 *
505 * All of the above can optionally be remapped through the GART. The following
506 * table lists the combinations of addressing types and GART remapping that
507 * is currently supported by the driver (h/w supports all, s/w limits this):
508 *
509 * PCI64 PCI32 AGP48
510 * GART no yes yes
511 * Direct yes yes no
512 *
513 * GART remapping of PCI64 is not done because there is no need to. The
514 * 64 bit PCI address holds all of the information necessary to target any
515 * memory in the system.
516 *
517 * AGP48 is always mapped through the GART. Management of the AGP48 portion
518 * of the aperature is the responsibility of code in the agpgart_be driver.
519 *
520 * The non-64 bit bus address space will currently be partitioned like this:
521 *
522 * 0xffff_ffff_ffff +--------
523 * | AGP48 direct
524 * | Space managed by this driver
525 * CA_AGP_DIRECT_BASE +--------
526 * | AGP GART mapped (gfx aperature)
527 * | Space managed by /dev/agpgart driver
528 * | This range is exposed to the agpgart
529 * | driver as the "graphics aperature"
530 * CA_AGP_MAPPED_BASE +-----
531 * | PCI GART mapped
532 * | Space managed by this driver
533 * CA_PCI32_MAPPED_BASE +----
534 * | PCI32 direct
535 * | Space managed by this driver
536 * 0xC000_0000 +--------
537 * (CA_PCI32_DIRECT_BASE)
538 *
539 * The bus address range CA_PCI32_MAPPED_BASE through CA_AGP_DIRECT_BASE
540 * is what we call the CA aperature. Addresses falling in this range will
541 * be remapped using the GART.
542 *
543 * The bus address range CA_AGP_MAPPED_BASE through CA_AGP_DIRECT_BASE
544 * is what we call the graphics aperature. This is a subset of the CA
545 * aperature and is under the control of the agpgart_be driver.
546 *
547 * CA_PCI32_MAPPED_BASE, CA_AGP_MAPPED_BASE, and CA_AGP_DIRECT_BASE are
548 * somewhat arbitrary values. The known constraints on choosing these is:
549 *
550 * 1) CA_AGP_DIRECT_BASE-CA_PCI32_MAPPED_BASE+1 (the CA aperature size)
551 * must be one of the values supported by the ca_gart_aperature register.
552 * Currently valid values are: 4MB through 4096MB in powers of 2 increments
553 *
554 * 2) CA_AGP_DIRECT_BASE-CA_AGP_MAPPED_BASE+1 (the gfx aperature size)
555 * must be in MB units since that's what the agpgart driver assumes.
556 */
557
558/*
559 * Define Bus DMA ranges. These are configurable (see constraints above)
560 * and will probably need tuning based on experience.
561 */
562
563
564/*
565 * 11/24/03
566 * CA has an addressing glitch w.r.t. PCI direct 32 bit DMA that makes it
567 * generally unusable. The problem is that for PCI direct 32
568 * DMA's, all 32 bits of the bus address are used to form the lower 32 bits
569 * of the coretalk address, and coretalk bits 38:32 come from a register.
570 * Since only PCI bus addresses 0xC0000000-0xFFFFFFFF (1GB) are available
571 * for DMA (the rest is allocated to PIO), host node addresses need to be
572 * such that their lower 32 bits fall in the 0xC0000000-0xffffffff range
573 * as well. So there can be no PCI32 direct DMA below 3GB!! For this
574 * reason we set the CA_PCI32_DIRECT_SIZE to 0 which essentially makes
575 * tioca_dma_direct32() a noop but preserves the code flow should this issue
576 * be fixed in a respin.
577 *
578 * For now, all PCI32 DMA's must be mapped through the GART.
