On some targets manual assignment of buffers to memory regions can improve memory bandwidth. This extension adds a buffer property to indicate in which memory channel a particular buffer should be allocated. This information is an optimization hint to the runtime and thus it is legal to ignore. Spec: intel#2688 Signed-off-by: Dmitry Sidorov <dmitry.sidorov@intel.com>

This extension adds a new buffer property to indicate which channel in a multi-channel memory a buffer should be allocated in. This can help to get the most of your memory bandwidth by strategically allocating buffers between channels. This was motivated by some FPGA boards but could be useful for other targets as well.
