| 64 | bool "Support sparse irq numbering" | |
| 65 | depends on HAVE_SPARSE_IRQ | |
| 66 | ---help--- | |
| 67 | ||
| 68 | Sparse irq numbering is useful for distro kernels that want | |
| 69 | to define a high CONFIG_NR_CPUS value but still want to have | |
| 70 | low kernel memory footprint on smaller machines. | |
| 71 | ||
| 72 | ( Sparse irqs can also be beneficial on NUMA boxes, as they spread | |
| 73 | out the interrupt descriptors in a more NUMA-friendly way. ) | |
| 74 | ||
| 75 | If you don't know what to do here, say N. | |
