Justin T. Gibbs daf6545e61 Enforce stronger semantics for bus-dma alignment (currently only on amd64). ... Now all contiguous regions returned from bus-dma will be aligned to the alignment constraint and all but the last region are guaranteed to be a multiple of the alignment in length. This also means that the relative alignment of two adjacent bytes in the I/O stream have a difference of 1 even if they are not physically contiguous. The old code, when needing to perform a copy in order to align data, only copied the amount of data needed to reach the next page boundary. This often left an unaligned end to the segment. Drivers such as Xen's blkfront can't deal with such segments. The downside to this approach is that, once an unaligned region is encountered, the remainder of the I/O will be bounced. However, bouncing should be rare. It is typically caused by non-performance critical userland programs that don't bother to align their I/O buffers (e.g. bsdlabel). In-kernel I/O buffers are always aligned to at least a page boundary. Reviewed by: scottl MFC after: 2 weeks		2010-02-22 17:03:45 +00:00
