|
|
This option selects local APIC as the interrupt controller.

config LOAPIC_BASE_ADDRESS
|

hex "Local APIC Base Address"

|

This option specifies the base address of the Local APIC device.

config IOAPIC
|
|
bool "IO-APIC"
|
|
default y
|
|
depends on LOAPIC
|
|
help
|
|
This option signifies that the target has an IO-APIC device. This
|
|
capability allows IO-APIC-dependent code to be included.

config IOAPIC_DEBUG

bool "IO-APIC Debugging"

depends on IOAPIC

|

Enable debugging for IO-APIC driver.

config IOAPIC_BASE_ADDRESS
|
|
hex "IO-APIC Base Address"
|
|
default 0xFEC00000
|
|
depends on IOAPIC
|

help
|
|
This option specifies the base address of the IO-APIC device.

config IOAPIC_NUM_RTES
|
|
int "Number of Redirection Table Entries available"
|
|
default 24
|
|
depends on IOAPIC
|
|
help
|
|
This option indicates the maximum number of Redirection Table Entries
|
|
(RTEs) (one per IRQ available to the IO-APIC) made available to the
|
|
kernel, regardless of the number provided by the hardware itself. For
|
|
most efficient usage of memory, it should match the number of IRQ lines
|
|
needed by devices connected to the IO-APIC.

config ARCV2_INTERRUPT_UNIT
|
|
bool "ARCv2 Interrupt Unit"
|
|
default y
|
|
depends on ARC
|
|
help
|
|
The ARCv2 interrupt unit has 16 allocated exceptions associated with
|
|
vectors 0 to 15 and 240 interrupts associated with vectors 16 to 255.
|
|
The interrupt unit is optional in the ARCv2-based processors. When
|
|
building a processor, you can configure the processor to include an
|
|
interrupt unit. The ARCv2 interrupt unit is highly programmable.
