2 bool "Userspace interrupt masking support"
3 depends on ARCH_SHMOBILE || (SUPERH && CPU_SH4A)
4 help
5 This enables support for hardware-assisted userspace hardirq
6 masking.
7
8 SH-4A and newer interrupt blocks all support a special shadowed
9 page with all non-masking registers obscured when mapped in to
10 userspace. This is primarily for use by userspace device
11 drivers that are using special priority levels.

13 If in doubt, say N.

15config INTC_BALANCING
16 bool "Hardware IRQ balancing support"
17 depends on SMP && SUPERH && CPU_SUBTYPE_SH7786
18 help
19 This enables support for IRQ auto-distribution mode on SH-X3
20 SMP parts. All of the balancing and CPU wakeup decisions are
21 taken care of automatically by hardware for distributed
22 vectors.
