This is the purpose that linux-next serves, not the x86 forest-of-doom. And I thought Ingo said his old iommu tree wasn't in there anyway? He said it was somewhere else, although I haven't actually managed to _find_ it. The Intel IOMMU appears on IA64 too, and doesn't want to be developed and tested off in an x86-specific corner by itself. And I'm going to be looking at other generic things we can do to improve IOMMU-related performance, which will touch on other architectures too. -- David Woodhouse Open Source Technology Centre David.Woodhouse@intel.com Intel Corporation -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
