59 | bool "Support sparse irq numbering" | |
60 | depends on HAVE_SPARSE_IRQ | |
61 | ---help--- | |
62 | ||
63 | Sparse irq numbering is useful for distro kernels that want | |
64 | to define a high CONFIG_NR_CPUS value but still want to have | |
65 | low kernel memory footprint on smaller machines. | |
66 | ||
67 | ( Sparse irqs can also be beneficial on NUMA boxes, as they spread | |
68 | out the interrupt descriptors in a more NUMA-friendly way. ) | |
69 | ||
70 | If you don't know what to do here, say N. | |
