vxworks下如何打印PowerPC的中断向量表内容

Q: 如何打印PowerPC的中断向量表内容，比如mv5100或者mv6100的中断向量表，以查看对应的向量绑接的ISR。

A: 只要打印sysIntTbl[]的内容就可以了。示例程序如下：

void intConnectShow (void)

{

IMPORT INT_HANDLER_DESC * sysIntTbl [256];

INT_HANDLER_DESC * handler;

int i;

printf ("\n Vector : Handler (Arg)\n\n");

for (i=0; i<=255; i++)

{

if( (handler = sysIntTbl[i]) != NULL )

{

printf ("%3d (0x%02x): 0x%x (0x%x)\n",

i,i, (UINT32)handler->vec, handler->arg);

handler = handler->next;

while (handler != NULL) // 处理链式绑接的ISR

{

printf(" 0x%x (0x%x) - chained\n",

(UINT32)handler->vec, handler->arg);

handler = handler->next;

}

}

}

printf("\n");

}
