+=================
+调试PA-RISC
+=================
+
+好吧,这里有一些关于调试linux/parisc的较底层部分的信息。
+
+
+1. 绝对地址
+=====================
+
+很多汇编代码目前运行在实模式下,这意味着会使用绝对地址,而不是像内核其他
+部分那样使用虚拟地址。要将绝对地址转换为虚拟地址,你可以在System.map中查
+找,添加__PAGE_OFFSET(目前是0x10000000)。
+
+
+2. HPMCs
+========
+
+当实模式的代码试图访问不存在的内存时,会出现HPMC(high priority machine
+check)而不是内核oops。若要调试HPMC,请尝试找到系统响应程序/请求程序地址。
+系统请求程序地址应该与(某)处理器的HPA(I/O范围内的高地址)相匹配;系统响应程
+序地址是实模式代码试图访问的地址。
+
+系统响应程序地址的典型值是大于__PAGE_OFFSET (0x10000000)的地址,这意味着
+在实模式试图访问它之前,虚拟地址没有被翻译成物理地址。
+
+
+3. 有趣的Q位
+============
+
+某些非常关键的代码必须清除PSW中的Q位。当Q位被清除时,CPU不会更新中断处理
+程序所读取的寄存器,以找出机器被中断的位置——所以如果你在清除Q位的指令和再
+次设置Q位的RFI之间遇到中断,你不知道它到底发生在哪里。如果你幸运的话,IAOQ
+会指向清除Q位的指令,如果你不幸运的话,它会指向任何地方。通常Q位的问题会
+表现为无法解释的系统挂起或物理内存越界。
