| 39 | bool "Support sparse irq numbering" | |
| 40 | depends on HAVE_SPARSE_IRQ | |
| 41 | ---help--- | |
| 42 | ||
| 43 | Sparse irq numbering is useful for distro kernels that want | |
| 44 | to define a high CONFIG_NR_CPUS value but still want to have | |
| 45 | low kernel memory footprint on smaller machines. | |
| 46 | ||
| 47 | ( Sparse irqs can also be beneficial on NUMA boxes, as they spread | |
| 48 | out the interrupt descriptors in a more NUMA-friendly way. ) | |
| 49 | ||
| 50 | If you don't know what to do here, say N. | |
