cognet	b0b19280da	- Add bounce pages for arm, largely based on the i386 implementation. ... - Add a default parent dma tag, similar to what has been done for sparc64. - Before invalidating the dcache in POSTREAD, save the bits which are in the same cachelines than our buffers, but not part of it, and restore them after the invalidation.	2007-01-17 00:53:05 +00:00
scottl	7be505a035	Refactor the bus_dma header files so that the interface is described in ... sys/bus_dma.h instead of being copied in every single arch. This slightly reorders a flag that was specific to AXP and thus changes the ABI there. The interface still relies on bus_space definitions found in <machine/bus.h> so it cannot be included on its own yet, but that will be fixed at a later date. Add an MD <machine/bus_dma.h> for ever arch for consistency and to allow for future MD augmentation of the API. sparc64 makes heavy use of this right now due to its different bus_dma implemenation.	2005-03-14 16:46:28 +00:00
