| config INTC_USERIMASK |
| bool "Userspace interrupt masking support" |
| 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. |
| |
| config INTC_BALANCING |
| bool "Hardware IRQ balancing support" |
| depends on SMP && SUPERH && CPU_SHX3 |
| 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. |
| |
| If in doubt, say N. |
| |
| config INTC_MAPPING_DEBUG |
| bool "Expose IRQ to per-controller id mapping via debugfs" |
| depends on DEBUG_FS |
| help |
| This will create a debugfs entry for showing the relationship |
| between system IRQs and the per-controller id tables. |
| |
| If in doubt, say N. |
