-/* - * DMA space - * - * The CA aperature (ie. bus address range) mapped by the GART is segmented into - * two parts. The lower portion of the aperature is used for mapping 32 bit - * PCI addresses which are managed by the dma interfaces in this file. The - * upper poprtion of the aperature is used for mapping 48 bit AGP addresses. - * The AGP portion of the aperature is managed by the agpgart_be.c driver - * in drivers/linux/agp. There are ca-specific hooks in that driver to - * manipulate the gart, but management of the AGP portion of the aperature - * is the responsibility of that driver. - * - * CA allows three main types of DMA mapping: - * - * PCI 64-bit Managed by this driver - * PCI 32-bit Managed by this driver - * AGP 48-bit Managed by hooks in the /dev/agpgart driver - * - * All of the above can optionally be remapped through the GART. The following - * table lists the combinations of addressing types and GART remapping that - * is currently supported by the driver (h/w supports all, s/w limits this): - * - * PCI64 PCI32 AGP48 - * GART no yes yes - * Direct yes yes no - * - * GART remapping of PCI64 is not done because there is no need to. The - * 64 bit PCI address holds all of the information necessary to target any - * memory in the system. - * - * AGP48 is always mapped through the GART. Management of the AGP48 portion - * of the aperature is the responsibility of code in the agpgart_be driver. - * - * The non-64 bit bus address space will currently be partitioned like this: - * - * 0xffff_ffff_ffff +-------- - * | AGP48 direct - * | Space managed by this driver - * CA_AGP_DIRECT_BASE +-------- - * | AGP GART mapped (gfx aperature) - * | Space managed by /dev/agpgart driver - * | This range is exposed to the agpgart - * | driver as the "graphics aperature" - * CA_AGP_MAPPED_BASE +----- - * | PCI GART mapped - * | Space managed by this driver - * CA_PCI32_MAPPED_BASE +---- - * | PCI32 direct - * | Space managed by this driver - * 0xC000_0000 +-------- - * (CA_PCI32_DIRECT_BASE) - * - * The bus address range CA_PCI32_MAPPED_BASE through CA_AGP_DIRECT_BASE - * is what we call the CA aperature. Addresses falling in this range will - * be remapped using the GART. - * - * The bus address range CA_AGP_MAPPED_BASE through CA_AGP_DIRECT_BASE - * is what we call the graphics aperature. This is a subset of the CA - * aperature and is under the control of the agpgart_be driver. - * - * CA_PCI32_MAPPED_BASE, CA_AGP_MAPPED_BASE, and CA_AGP_DIRECT_BASE are - * somewhat arbitrary values. The known constraints on choosing these is: - * - * 1) CA_AGP_DIRECT_BASE-CA_PCI32_MAPPED_BASE+1 (the CA aperature size) - * must be one of the values supported by the ca_gart_aperature register. - * Currently valid values are: 4MB through 4096MB in powers of 2 increments - * - * 2) CA_AGP_DIRECT_BASE-CA_AGP_MAPPED_BASE+1 (the gfx aperature size) - * must be in MB units since that's what the agpgart driver assumes. - */ - -/* - * Define Bus DMA ranges. These are configurable (see constraints above) - * and will probably need tuning based on experience. - */ - - -/* - * 11/24/03 - * CA has an addressing glitch w.r.t. PCI direct 32 bit DMA that makes it - * generally unusable. The problem is that for PCI direct 32 - * DMA's, all 32 bits of the bus address are used to form the lower 32 bits - * of the coretalk address, and coretalk bits 38:32 come from a register. - * Since only PCI bus addresses 0xC0000000-0xFFFFFFFF (1GB) are available - * for DMA (the rest is allocated to PIO), host node addresses need to be - * such that their lower 32 bits fall in the 0xC0000000-0xffffffff range - * as well. So there can be no PCI32 direct DMA below 3GB!! For this - * reason we set the CA_PCI32_DIRECT_SIZE to 0 which essentially makes - * tioca_dma_direct32() a noop but preserves the code flow should this issue - * be fixed in a respin. - * - * For now, all PCI32 DMA's must be mapped through the GART. - */ - -#define CA_PCI32_DIRECT_BASE 0xC0000000UL /* BASE not configurable */ -#define CA_PCI32_DIRECT_SIZE 0x00000000UL /* 0 MB */ - -#define CA_PCI32_MAPPED_BASE 0xC0000000UL -#define CA_PCI32_MAPPED_SIZE 0x40000000UL /* 2GB */ - -#define CA_AGP_MAPPED_BASE 0x80000000UL -#define CA_AGP_MAPPED_SIZE 0x40000000UL /* 2GB */ - -#define CA_AGP_DIRECT_BASE 0x40000000UL /* 2GB */ -#define CA_AGP_DIRECT_SIZE 0x40000000UL - -#define CA_APERATURE_BASE (CA_AGP_MAPPED_BASE) -#define CA_APERATURE_SIZE (CA_AGP_MAPPED_SIZE+CA_PCI32_MAPPED_SIZE) - -#endif /* _ASM_IA64_SN_TIO_TIOCA_H */ |
