config IRQ_DOMAIN_DEBUG bool "Expose hardware/virtual IRQ mapping via debugfs" depends on IRQ_DOMAIN && DEBUG_FS help This option will show the mapping relationship between hardware irq numbers and Linux irq numbers. The mapping is exposed via debugfs in the file "irq_domain_mapping".
If you don't know what this means you don't need it.
Support forced irq threading
config IRQ_FORCED_THREADING bool
config SPARSE_IRQ bool "Support sparse irq numbering" if MAY_HAVE_SPARSE_IRQ ---help---
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.
