Every e820 map i've seen did not have the AGP aperture marked reserved. It is just an undescribed hole. In fact when you mark the aperture in the e820 map the Linux AGP driver stops working, it relies on it being in an undescribed hole. This means you cannot just reuse holes. And there is no other way to get mapping space. -Andi - 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/
