I guess down the line we might want to think about making all the externally visible knobs transparent: there should be only one way to disable the iommu via the boot command line (be that an AMD or Intel one), etc. i have created a new -tip topic for this: tip/x86/amd-iommu and have applied your patches there - thanks Joerg. You can pick up the integrated tree via: http://people.redhat.com/mingo/tip.git/README please check whether the integrated end result still works fine. [ Obviously nobody but you can test this on real hw ;-) ] Ingo -- 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/
