select IRQ_DOMAIN

comment "Interrupt controller options"
config INTC_USERIMASK
bool "Userspace interrupt masking support"
depends on (SUPERH && CPU_SH4A) || COMPILE_TEST
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.
