No need to include pci_kn8ae.h here.

Moar static.

malloc(9) -> kmem(9)

Add some bus_dma instrumentation.

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

Mostly merge changes from HEAD upto 20200411

in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT
and remove code to handle failures that can no longer happen.

Rebase to HEAD as of a few days ago.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

gc sprintf; reduce local static usage of interrupt strings that are only
used once for autoconf printing.

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>.

Catchup with rmind-uvmplock merge.

Major cleanup of alpha device drivers.
Switch to CFATTACH_DECL_NEW.
struct device * -> device_t
struct cfdata * -> cfdata_t
Use of device_xname.  No direct access to struct device members.
Use aprint* (not complete).

Remove unneeded includes of <uvm/uvm_extern.h>

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.

Remove clause 3 and 4 from TNF licenses

update to -current

DWLPx has a 256-byte DMA prefetch threshold.

file dwlpx_dma.c was added on branch nathanw_sa on 2001-07-19 18:59:42 +0000

DWLPx has a 256-byte DMA prefetch threshold.

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>

Sync w/ -current.

Pull up from trunk: copyright text warts.

Fix garbled words in copyright statement.

Nuke an unused variable.

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

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.

Redo it slightly so that S/G now appears to work a bit better. This
version has 2GB direct map starting at 2GB, and either 256MB or 1GB
S/G starting at 1MB. I've done *some* testing on this, but I'm not
quite happy with it yet.

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

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 dwlpx_dma.c was added on branch alpha-nwscons on 1997-06-07 04:43:21 +0000

Pull thorpej-bus-dma branch into mainline.

Update for pci_pte*_sgmap -> pci_sgmap_pte* change.

Oops, convert page table address (phys) to a K0SEG address that the CPU
can use.  Rearrange slightly to make it less easy to screw this up.

- Adopt to new common sgmap code.
- Fix several bugs, and reduce housekeeping overhead.
- Add support for sgmap-mapped DMA on the DWLPx.

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 dwlpx_dma.c was initially added on branch thorpej-bus-dma.
