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 */
