Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

An AVANTI *might* be an XL, and an XL has only 27 bits of ISA address
|
|
that get passed through the PCI<->ISA bridge chip. So we've gotta use
|
|
both windows to max out the physical memory we can DMA to. 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. It is true,
|
|
however, that an XL kernel will run on an AVANTI without problems.
|
|
|
|
%%% All of this should be obviated by the ability to route
|
|
everything through the iommu.
