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