This is primarily for use by userspace device 13 drivers that are using special priority levels. 14 15 If in doubt, say N. 16 17config INTC_BALANCING 18 bool "Hardware IRQ balancing support" 19 depends on SMP && SUPERH && CPU_SHX3 20 help 21 This enables support for IRQ auto-distribution mode on SH-X3 22 SMP parts. All of the balancing and CPU wakeup decisions are 23 taken care of automatically by hardware for distributed 24 vectors. 25 26 If in doubt, say N. 27 28config INTC_MAPPING_DEBUG 29 bool "Expose IRQ to per-controller id mapping via debugfs" 30 depends on DEBUG_FS 31 help 32 This will create a debugfs entry for showing the relationship 33 between system IRQs and the per-controller id tables. 34 35 If in doubt, say N. 36
