1config INTC_USERIMASK
2	bool "Userspace interrupt masking support"

4	help
5	  This enables support for hardware-assisted userspace hardirq
6	  masking.

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.

16	bool "Hardware IRQ balancing support"
17	depends on SMP && SUPERH && CPU_SHX3
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.
