36 | bool "Support sparse irq numbering" | |
37 | depends on HAVE_SPARSE_IRQ | |
38 | ---help--- | |
39 | ||
40 | Sparse irq numbering is useful for distro kernels that want | |
41 | to define a high CONFIG_NR_CPUS value but still want to have | |
42 | low kernel memory footprint on smaller machines. | |
43 | ||
44 | ( Sparse irqs can also be beneficial on NUMA boxes, as they spread | |
45 | out the interrupt descriptors in a more NUMA-friendly way. ) | |
46 | ||
47 | If you don't know what to do here, say N. | |
