config INTC_USERIMASK

bool "Userspace interrupt masking support"

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.
