1config INTC_USERIMASK 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. 12 13 If in doubt, say N. 14 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.
