1 | config 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. | |

13 | If in doubt, say N. | |

15 | config 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. | |
