| 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. | ||
