drochner 5e990a7f7c implement bus_space_vaddr() 2000-04-17 17:39:17 +00:00
drochner 8eb798e603 define a "BUS_SPACE_MAP_PREFETCHABLE" flag which basically means that
device accesses are idempotent (but should not be cached by the CPU)

cgd 7c02d93c04 nuke current definitions provided by __BUS_SPACE_COMPAT_OLDDEFS.
I'll do what I can to make new ones soon.  8-)

mrg c17a4018cb pull in new (?) BUS_SPACE_BARRIER_{READ,WRITE} definitions. 1999-03-29 12:42:51 +00:00
drochner 76fa1751fe Add a macro to check for sufficient pointer alignment in bus.h context,
"BUS_SPACE_ALIGNED_POINTER()".
Equal to the param.h "ALIGNED_POINTER()" normally, but obeys additional
requirements of the bus_space_xxx_n() macros. (BUS_SPACE_DEBUG)

mark 53f576f788 bus_space_copy_* -> bus_space_copy_region_*
Add BUS_SPACE_COMPAT_OLDDEFS for bus_space_copy_* compat.

thorpej 46320bb017 Clean up the bus space function namespace somewhat; make sure they don't
collide with function names used in other parts of the kernel.

thorpej 3497ab9a8c Add a pointer to an array of DMA ranges. DMA buffers must lie within
a range, or else an error is returned when loading a map.  If the ranges
pointer is NULL, no range checks are performed.

thorpej a4e8fc45cd Nuke the _cookie member of the bus_dma_tag_t; it's not used by anything. 1998-06-27 02:16:23 +00:00
thorpej 06f1469055 Really namespace-protect the virtual address in the DMA segment structure. 1998-06-27 02:13:39 +00:00
mark fcc1093bee Define bus_space_map flags BUS_SPACE_MAP_CACHEABLE and BUS_SPACE_MAP_LINEAR.
Comment arm32_bus_dma_segment structure members.
Remove the _dm_loadlen field from the arm32_bus_dmamap structure.
1998-04-19 04:13:24 +00:00
thorpej 8abe76d2f0 Add offset and length parameters to bus_dmamap_sync(), used for specifiying
partial syncs of a DMA mapping.
1998-02-04 05:12:46 +00:00
thorpej 99cc8482d1 Change the last argument of bus_dmamap_sync() from bus_dmasync_op_t to int,
and allow more than one synchronization operation to be specified in
a single call.  Dissallow mixing of PRE and POST operations.
1998-02-04 01:57:27 +00:00
thorpej 4e7c05e588 Add dm_mapsize to bus_dmamap_t and rename BUS_DMAMEM_NOSYNC to
BUS_DMA_COHERENT.

mark fb9c150c48 arm32 kernel source restructure
- Most changes are comment cleanups.
  _ iomd.h is no longer an exported header.
  - Added intr.h for MI interrupt definitions.
  - Added definitions for ARM8 cpu.
  - Added bus dma support.

mark de7c5e2195 Implement the bus space interfaces for set multiple, set region and copy. 1997-01-26 01:49:01 +00:00
mark 0bebac783d Update for new bus space interface. This implementation is based on
cgd's alpha implementation. Bus tags now point to a structure of
function pointers to bus space routines rather than being an index to
one of several I/O methods making it simpler and more efficient in
handling many different busses and mapping schemes.

mark 0d476cb7d0 bus memory and I/O space access functions/macros, to be used by
machine-independent code for more sane access to bus resources.
Defines:
        bus_{io,mem}_{map,unmap}
        bus_{io,mem}_{read,write}_{1,2,4,8}
        bus_io_{read,write}_multi_{1,2,4,8}
functions, and several types to go with them.
Note: The bus_io_*_8 functions are not supported.
