In that case, NetIO will by - default ignore the suggested buffer node weights, and buffers - will be striped across the physical memory controllers. See - UG209 System Programmer's Guide for a description of the - hypervisor option that controls memory striping. - - If memory striping is disabled, then there are up to four NUMA - nodes, corresponding to the four DDRAM controllers in the TILE - processor architecture. See UG100 Tile Processor Architecture - Overview for a diagram showing the location of each of the DDRAM - controllers relative to the tile array. - - For instance, if memory striping is disabled, the following - configuration strucure: - - @code - netio_input_config_t config = { - . - . - . - .total_buffer_size = 4 * 16 * 1024 * 1024; - .buffer_node_weights = { 1, 0, 1, 0 }, - }, - @endcode - - would result in 32 MB of buffers being placed on controller 0, and - 32 MB on controller 2. (Since buffers are allocated in units of - 16 MB, some sets of weights will not be able to be matched exactly.) - - For the weights to be effective, @ref total_buffer_size must be - nonzero. If @ref total_buffer_size is zero, causing the default - 32 MB of buffer space to be used, then any specified weights will - be ignored, and buffers will positioned as they were in previous - versions of NetIO: - - - For xgbe/0 and gbe/0, 16 MB of buffers will be placed on controller 1, - and the other 16 MB will be placed on controller 2. - - - For xgbe/1 and gbe/1, 16 MB of buffers will be placed on controller 2, - and the other 16 MB will be placed on controller 3. - - If @ref total_buffer_size is nonzero, but all weights are zero, - then all buffer space will be allocated on Linux NUMA node zero. - - By default, the specified buffer placement is treated as a hint; - if sufficient free memory is not available on the specified - controllers, the buffers will be allocated elsewhere. However, - if the ::NETIO_STRICT_HOMING flag is specified in @ref flags, then a - failure to allocate buffer space exactly as requested will cause the - registration operation to fail with an error of ::NETIO_CANNOT_HOME. - - Note that maximal network performance cannot be achieved with - only one memory controller. - */ - uint8_t buffer_node_weights[NETIO_NUM_NODE_WEIGHTS]; - - /** Fixed virtual address for packet buffers.
