#define SYSINTR_UNDEFINED (-1) // SysIntr not defined for IRQ <-> SYSINTR mapping

#define SYSINTR_NOP         0   /* no processing required */
#define SYSINTR_RESCHED     1   /* set "reschedule flag" */
#define SYSINTR_BREAK       2   /* break into debugger */
#define SYSINTR_CHAIN       3   /* continue to next handler */

// SYSINTR_DEVICES is the base for any non-OAL system interrupts
#define SYSINTR_DEVICES 8

#define SYSINTR_PROFILE             (SYSINTR_DEVICES+1)     // System Profiling
#define SYSINTR_TIMING              (SYSINTR_DEVICES+2)     // Latency Analysis
#define SYSINTR_RTC_ALARM           (SYSINTR_DEVICES+5)     // real-time clock alarm
#define SYSINTR_NETWORK_SHARED      (SYSINTR_DEVICES+6)     // Combined interrupts for network
#define SYSINTR_VMINI               (SYSINTR_DEVICES+7)     // VMini RX interrupt.

// SYSINTR_FIRMWARE is the base for any interrupts defined in the OAL
#define SYSINTR_FIRMWARE (SYSINTR_DEVICES+8)

#define SYSINTR_MAX_DEVICES 64
#define SYSINTR_MAXIMUM (SYSINTR_DEVICES+SYSINTR_MAX_DEVICES)

说明：系统中断号定义
