Yes, we can per-page flush, but I don't use that feature at all since I do the "flush all when wrap around IOMMU pte table" thing we're discussing. In fact there is no "global flush" so what I have to do is use diagnostic accesses to the IOMMU TLB to kick out the entries one by one. - 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/
