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

Allow storage-space to be passed to the alloc_bus_space_tag() functions. This
...
permits static tags to be used during early console init.

Change the copy_region function to shutup gcc's unused warnings in some
...
cases. Use the bus_space_tag without doing something useful... (idea from
Matthias Drochner).

Use extent maps.

Correct the argument order for memcpy(). This tremendously improves the
...
behaviour of wscons.... (Why did history create both bcopy & memcpy?)

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)

Make the abs_copy functions usable. The previous implementation caused
...
kernel "jump to zero" panics....

Fix the __abs_copy() macro (wrong parameters to __abs_opname).

Add bus_space_{read,write}_region_stream_N functions.

Major overhaul of the atari bus_space implementation.
1998-04-10 08:19:53 +00:00

Bus-dma implementation for the atari. Heavily based on the i386
...
implementation.

Add: bus_space_{read,write}_region_N() and bus_space_set_{multi,region}_N()
...
functions.

Add BUS_SPACE_MAP_* macro's.

Implement bus_space_subregion()
1997-07-15 06:49:56 +00:00
61d060feec
Add the types for 'bus_dma_tag_t' and 'bus_dmamap_t'. While here, be a bit
...
more precise in using types of the bus_space* address arguments.
1997-06-25 12:06:10 +00:00
b170f473ba
Add bus_space_peek_[1248] functions. These can be used by match/probe
...
functions.

Fix typo's in last commit.
1997-01-27 10:18:33 +00:00

Change the type of bus_space_tag_t.
...
Add the bus_space_(read|write)* functions.

Adapt to changes in the bus-interface; bus_[mem|io] -> bus_space. Thanks Jason.

Prototytpe bus_mem_map/bus_mem_unmap functions.

Minimal bus.h. Together with the minimal pci implementation, we have just
...
enough functionality to find a VGA card....
Will be expanded when I buy more pci-cards ;-)
