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