Sigh... - - If we try a window at 0 for 1GB as a work-around, we run into conflicts - with ISA/PCI bus memory which can't be relocated, like VGA aperture and - BIOS ROMs. So we must put the windows high enough to avoid these areas. - - We put window 1 at BUS 64Mb for 64Mb, mapping physical 0 to 64Mb-1, - and window 2 at BUS 1Gb for 1Gb, mapping physical 0 to 1Gb-1. - Yes, this does map 0 to 64Mb-1 twice, but only window 1 will actually - be used for that range (via virt_to_bus()). - - Note that we actually fudge the window 1 maximum as 48Mb instead of 64Mb, - to keep virt_to_bus() from returning an address in the first window, for - a data area that goes beyond the 64Mb first DMA window. Sigh... - The fudge factor MUST match with <asm/dma.h> MAX_DMA_ADDRESS, but - we can't just use that here, because of header file looping... :-( - - Window 1 will be used for all DMA from the ISA bus; yes, that does - limit what memory an ISA floppy or sound card or Ethernet can touch, but - it's also a known limitation on other platforms as well. We use the - same technique that is used on INTEL platforms with similar limitation: - set MAX_DMA_ADDRESS and clear some pages' DMAable flags during mem_init(). - We trust that any ISA bus device drivers will *always* ask for DMAable - memory explicitly via kmalloc()/get_free_pages() flags arguments. - - Note that most PCI bus devices' drivers do *not* explicitly ask for - DMAable memory; they count on being able to DMA to any memory they - get from kmalloc()/get_free_pages(). They will also use window 1 for - any physical memory accesses below 64Mb; the rest will be handled by - window 2, maxing out at 1Gb of memory. I trust this is enough... :-) - - We hope that the area before the first window is large enough so that - there will be no overlap at the top end (64Mb). We *must* locate the - PCI cards' memory just below window 1, so that there's still the - possibility of being able to access it via SPARSE space. This is - important for cards such as the Matrox Millennium, whose Xserver - wants to access memory-mapped registers in byte and short lengths. - - Note that the XL is treated differently from the AVANTI, even though - for most other things they are identical. It didn't seem reasonable to - make the AVANTI support pay for the limitations of the XL.
