This option will disable sparse memory support and force the kernel to manage all memory in one node. Setting this option incorrectly may prevent the kernel from booting. It is OK to leave it N. For more information, consult . config LH7A40X_ONE_BANK_PER_NODE bool "Optimize NUMA Node Tables for Size" depends on !LH7A40X_CONTIGMEM help Say Y here to produce compact memory node tables. By default pairs of adjacent physical RAM banks are managed together in a single node, incurring some wasted overhead in the node tables, however also maintaining compatibility with systems where physical memory is truly contiguous. Setting this option incorrectly may prevent the kernel from booting. It is OK to leave it N. For more information, consult . endmenu endif
