config SH_INTC bool select IRQ_DOMAIN

if SH_INTC

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.
