8 bool "Userspace interrupt masking support"
9 depends on ARCH_SHMOBILE || (SUPERH && CPU_SH4A)
11 This enables support for hardware-assisted userspace hardirq
14 SH-4A and newer interrupt blocks all support a special shadowed
15 page with all non-masking registers obscured when mapped in to
16 userspace. This is primarily for use by userspace device
17 drivers that are using special priority levels.
22 bool "Hardware IRQ balancing support"
23 depends on SMP && SUPERH && CPU_SHX3
25 This enables support for IRQ auto-distribution mode on SH-X3
26 SMP parts. All of the balancing and CPU wakeup decisions are
27 taken care of automatically by hardware for distributed
32 config INTC_MAPPING_DEBUG
33 bool "Expose IRQ to per-controller id mapping via debugfs"
36 This will create a debugfs entry for showing the relationship
37 between system IRQs and the per-controller id tables.
