marius 2011-03-11 22:42:04 UTC FreeBSD src repository Modified files: sys/dev/sound/pcm buffer.c Log: SVN rev 219548 on 2011-03-11 22:42:04Z by marius Allocate the sound buffer DMA memory coherent. While NetBSD typically also does this for sound drivers it's probably not necessary for all combinations of controllers and drivers. However, given that our sound drivers completely lack bus_dmamap_sync(9) calls this at least serves as a workaround when enabling use of the IOMMU streaming buffers on sparc64 and generally for arm and mips.
