[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] simple question on frontend network driver and decreasing reservation
the frontend driver, in network_alloc_rx_buffers, allocates pages and then hands them off to xen for the rx ring, using MEMOP_decrease_reservation. Just checking, but I assume this actually decreases the domain's allowed memory footprint? At poll_if time, it reclaims pages from the rx queue by mapping them back in (I hope I got this right). Now I assume that as it pulls those pages back in to the domain, the domain's allowed page count is increased for each page it pulls in? Just curious. thanks ron ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
