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.
