- 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.
