| depends on ARCH_SHMOBILE || (SUPERH && CPU_SH4A) | |
| help | |
| This enables support for hardware-assisted userspace hardirq | |
| masking. | |
| SH-4A and newer interrupt blocks all support a special shadowed | |
| page with all non-masking registers obscured when mapped in to | |
| userspace. This is primarily for use by userspace device | |
| drivers that are using special priority levels. | |
| If in doubt, say N. | |

| bool "Hardware IRQ balancing support" | |
| depends on SMP && SUPERH && CPU_SUBTYPE_SH7786 | |
| help | |
| This enables support for IRQ auto-distribution mode on SH-X3 | |
| SMP parts. All of the balancing and CPU wakeup decisions are | |
| taken care of automatically by hardware for distributed | |
| vectors. | |
