After moving the the include files there were a few clean-ups: 1) Some files used #include <asm-ia64/xyz.h>, changed to <asm/xyz.h> 2) Some comments alerted maintainers to look at various header files to make matching updates if certain code were to be changed. Updated these comments to use the new include paths. 3) Some header files mentioned their own names in initial comments. Just deleted these self references.

/*
|
|
* 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.
