40 | bool "Support sparse irq numbering" | |
41 | depends on HAVE_SPARSE_IRQ | |
42 | ---help--- | |
43 | ||
44 | Sparse irq numbering is useful for distro kernels that want | |
45 | to define a high CONFIG_NR_CPUS value but still want to have | |
46 | low kernel memory footprint on smaller machines. | |
47 | ||
48 | ( Sparse irqs can also be beneficial on NUMA boxes, as they spread | |
49 | out the interrupt descriptors in a more NUMA-friendly way. ) | |
50 | ||
51 | If you don't know what to do here, say N. | |
