fix various typos in comments.

Sync with HEAD.

Remove unnecessary #include <sys/malloc.h>

Sync with HEAD.

Moar static.

Add some bus_dma instrumentation.

G/C alpha_XXX_dmamap() / alpha_XXX_dmamap_or.  They haven't been needed
for a long time.

sync with head

merge to -current.

Do a minor cleanup of alpha (this will make applying pullups post branching
easier).
u_int{8,16,32,64}_t -> uint{*}_t
Change all old-style definitions to C89 prototypes.
Whitespace cleanup.
Constification in db_disasm.c

#include <sys/bus.h> instead of <machine/bus.h>.

Remove unneeded includes of <uvm/uvm_extern.h>

Sync with HEAD.

Commit is split, to avoid a "too many arguments" protocol error.

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.

Fix the sync with head I botched.

Pull up revision 1.16 (requested by mycroft in ticket #582):
  Actually initialize the direct-mapped DMA window, which is
  clearly not set up by the firmware on the Multia.  Now
  devices like the built-in tlp actually work.

update to -current

The LCA isn't supposed to have a DMA prefetch threshold, but experience
has shown is that if we don't allocate a spill page, we get a machine
check.  So, initialize the threshold to 256 bytes.

Sync with HEAD

The code that creates/destroys SGMAP DMA maps is the same; put it
in a common place and share it.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>

vm_offset_t -> {paddr_t,vaddr_t}, vm_size_t -> vsize_t

Don't call *_dma_init() twice; there's no need to.  Just do it in *attach().

Allow the DMA tag to specify a boundary contraint.  If the device has a
more strict boundary, the map will use it, otherwise the map will inherit
the tag's, unless the tag's constraint is 0 (no boundary constraint).

Add support for chaining DMA windows together, for falling back on
SGMAPs if a direct-mapped window fails.

Simplify the direct-mapped DMA case somewhat by adding a window base
member to the DMA tag, and calling the direct-mapped back-ends directly,
rather than through chipset-specific front-ends which pass the window
base as an additional argument.

Use the common _bus_dmamap_sync() as the _dmamap_sync method in the
bus_dma_tag_t.

Initialize s/g DMA registers in the same order as the CIA chipset's:
	(1) window base
	(2) window mask
	(3) translation base

Put SGMAP-related stuff in the DMA map structure directly, rather than
indirecting through a pointer.

Update for "minptalign" argument to alpha_sgmap_init().

Update marc-pcmcia branch from trunk.

Nuke the idea of <machine/options.h>.  It completely defeats the purpose
of fine-grain option dependencies.

syng thorpej-bus-dma changes with alpha-nwscons branch

file lca_dma.c was added on branch alpha-nwscons on 1997-06-07 04:43:28 +0000

Pull thorpej-bus-dma branch into mainline.

Update for pci_pte*_sgmap -> pci_sgmap_pte* change.

When invalidating the SGMAP TLB, do a memory barrier synch before writing
the TBIA register, as well as after.

- Adopt to new common sgmap code.
- Fix several bugs, and reduce housekeeping overhead.

Add chipset-specific DMA functions.  For all of these chipsets, we have
one 1G direct-mapped DMA window at 1G and one 8M SGMAP-mapped DMA window
at 8M.

file lca_dma.c was initially added on branch thorpej-bus-dma.
