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