comment "Interrupt controller options" config INTC_USERIMASK bool "Userspace interrupt masking support" depends on ARCH_SHMOBILE || (SUPERH && CPU_SH4A) help This enables support for hardware-assisted userspace hardirq masking. SH-4A and newer interrupt blocks all support a special shadowed page with all non-masking registers obscured when mapped in to userspace. This is primarily for use by userspace device drivers that are using special priority levels. If in doubt, say N. config INTC_BALANCING bool "Hardware IRQ balancing support" depends on SMP && SUPERH && CPU_SHX3 help This enables support for IRQ auto-distribution mode on SH-X3 SMP parts. All of the balancing and CPU wakeup decisions are taken care of automatically by hardware for distributed vectors. If in doubt, say N. config INTC_MAPPING_DEBUG bool "Expose IRQ to per-controller id mapping via debugfs" depends on DEBUG_FS help This will create a debugfs entry for showing the relationship between system IRQs and the per-controller id tables. If in doubt, say N.
