define a "BUS_SPACE_MAP_PREFETCHABLE" flag which basically means that
...
device accesses are idempotent (but should not be cached by the CPU)

I'll do what I can to make new ones soon. 8-)

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)

...
fashion.

1998-06-09 05:53:30 +00:00
28486ff301
Remove the _cookie member of the DMA tag; it's not used by anything. (This
...
was already done to the i386 port.)

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
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.

Add bus_space_{read,write,set}_{,multi,region}_stream_{2,4,8}().
...
These methods would be used where "raw" data needs to
{read,write,set} unchanged.
Add define __BUS_SPACE_NEED_STREAM_METHODS.
