Sparse irq numbering is useful for distro kernels that want
|
||
|
|
to define a high CONFIG_NR_CPUS value but still want to have
|
||
|
|
low kernel memory footprint on smaller machines.
|
||
|
|
|
||
|
|
( Sparse irqs can also be beneficial on NUMA boxes, as they spread
|
||
|
|
out the interrupt descriptors in a more NUMA-friendly way. )
|
||
|
|
|
||
|
|
If you don't know what to do here, say N.
