The default is (or at least as of the last Xen kernel I tried) 2M unless your machine has massive amounts of RAM (>2G is the threshold, =2G will result in a 2M swiotlb like it does in my box).
swiotlb=64 without the force option works for me in dom0 on an AMD64 machine with a PVR-500. Running in a domU needs all that PCI redirection stuff, which I have never experimented with. (I now use Xen so that I could install trixbox without nuking and repaving my Gentoo installation.) _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
