  25    An AVANTI *might* be an XL, and an XL has only 27 bits of ISA address
  26    that get passed through the PCI<->ISA bridge chip. So we've gotta use
  27    both windows to max out the physical memory we can DMA to. Sigh...
  28 
  29    If we try a window at 0 for 1GB as a work-around, we run into conflicts
  30    with ISA/PCI bus memory which can't be relocated, like VGA aperture and
  31    BIOS ROMs. So we must put the windows high enough to avoid these areas.
  32 
  33    We put window 1 at BUS 64Mb for 64Mb, mapping physical 0 to 64Mb-1,
  34    and window 2 at BUS 1Gb for 1Gb, mapping physical 0 to 1Gb-1.
  35    Yes, this does map 0 to 64Mb-1 twice, but only window 1 will actually
  36    be used for that range (via virt_to_bus()).
  37 
  38    Note that we actually fudge the window 1 maximum as 48Mb instead of 64Mb,
  39    to keep virt_to_bus() from returning an address in the first window, for
  40    a data area that goes beyond the 64Mb first DMA window.  Sigh...
  41    The fudge factor MUST match with <asm/dma.h> MAX_DMA_ADDRESS, but
  42    we can't just use that here, because of header file looping... :-(
  43 
  44    Window 1 will be used for all DMA from the ISA bus; yes, that does
  45    limit what memory an ISA floppy or sound card or Ethernet can touch, but
  46    it's also a known limitation on other platforms as well. We use the
  47    same technique that is used on INTEL platforms with similar limitation:
  48    set MAX_DMA_ADDRESS and clear some pages' DMAable flags during mem_init().
  49    We trust that any ISA bus device drivers will *always* ask for DMAable
  50    memory explicitly via kmalloc()/get_free_pages() flags arguments.
  51 
  52    Note that most PCI bus devices' drivers do *not* explicitly ask for
  53    DMAable memory; they count on being able to DMA to any memory they
  54    get from kmalloc()/get_free_pages(). They will also use window 1 for
  55    any physical memory accesses below 64Mb; the rest will be handled by
  56    window 2, maxing out at 1Gb of memory. I trust this is enough... :-)
  57 
  58    We hope that the area before the first window is large enough so that
  59    there will be no overlap at the top end (64Mb). We *must* locate the
  60    PCI cards' memory just below window 1, so that there's still the
  61    possibility of being able to access it via SPARSE space. This is
  62    important for cards such as the Matrox Millennium, whose Xserver
  63    wants to access memory-mapped registers in byte and short lengths.
  64 
  65    Note that the XL is treated differently from the AVANTI, even though
  66    for most other things they are identical. It didn't seem reasonable to
  67    make the AVANTI support pay for the limitations of the XL. It is true,
  68    however, that an XL kernel will run on an AVANTI without problems.
  69 
  70    %%% All of this should be obviated by the ability to route
  71    everything through the iommu.
