Macros
#define	BSP_SHARED_HANDLER_SUPPORT 1
	Include some preprocessor value also used by assember code.

#define	BSP_IRQ_VECTOR_BASE BSP_ASM_IRQ_VECTOR_BASE
	Base vector for our IRQ handlers.

#define	BSP_IRQ_LINES_NUMBER 16

#define	BSP_IRQ_MAX_ON_i8259A (BSP_IRQ_LINES_NUMBER - 1)

#define	BSP_IRQ_VECTOR_NUMBER 17

#define	BSP_IRQ_VECTOR_LOWEST_OFFSET 0

#define	BSP_IRQ_VECTOR_MAX_OFFSET (BSP_IRQ_VECTOR_NUMBER - 1)

#define	BSP_PERIODIC_TIMER 0 /* fixed on all builds of PC */
	Interrupt offset in comparison to BSP_ASM_IRQ_VECTOR_BASE NB : 1) Interrupt vector number in IDT = offset + BSP_ASM_IRQ_VECTOR_BASE 2) The same name should be defined on all architecture so that handler connection can be unchanged.

#define	BSP_KEYBOARD 1 /* fixed on all builds of PC */

#define	BSP_UART_COM2_IRQ 3 /* fixed for ISA bus */

#define	BSP_UART_COM1_IRQ 4 /* fixed for ISA bus */

#define	BSP_UART_COM3_IRQ 5

#define	BSP_UART_COM4_IRQ 6

#define	BSP_RT_TIMER1 8

#define	BSP_RT_TIMER3 10

#define	BSP_SMP_IPI 16 /* not part of the ATPIC */

#define	BSP_INTERRUPT_VECTOR_MIN BSP_IRQ_VECTOR_LOWEST_OFFSET

#define	BSP_INTERRUPT_VECTOR_MAX BSP_IRQ_VECTOR_MAX_OFFSET

Typedefs
typedef unsigned short	rtems_i8259_masks
	Type definition for RTEMS managed interrupts.
