DebugView不能捕获KdPrint输出 [英] DebugView doesn't capture KdPrint output

问题描述

我无法使DbgView.exe在Windows 10 64位v2004虚拟机上正常运行.如果使用KdPrint，该程序不会捕获来自驱动程序的任何内核消息，但可以与DbgPrint一起正常工作.我已经尝试过"bcdedit/debug on"，并在其中添加了"Debug Print Filter".在注册表编辑器上并重新启动，从而启用详细的内核输出. 我也在主机上尝试过，同样的结果. 这是一个非常简单的驱动程序，只能从Windows Kernel Programming一书中复制和卸载.

I cannot make DbgView.exe work properly on my Windows 10 64-bit v2004 Virtual Machine. The program doesn't capture any kernel message from the driver if using KdPrint, but works fine with DbgPrint. I've already tried "bcdedit /debug on", adding "Debug Print Filter" on the registry editor and rebooting, enabling verbose kernel output. I've also tried on my host machine, same outcome. It is a very simple driver, only to be loaded and unloaded, copied from the book Windows Kernel Programming.

这有效

DbgPrint("Driver initialized.\n");

这不是

KdPrint(("Driver initialized.\n"));

任何帮助将不胜感激！

推荐答案

跳转到KdPrint，您将看到预处理魔术:

Jump to KdPrint and you will see a preprocessing magic:

#if DBG 

#define KdPrint(_x_) DbgPrint _x_
#define KdPrintEx(_x_) DbgPrintEx _x_ 
#define vKdPrintEx(_x_) vDbgPrintEx _x_
#define vKdPrintExWithPrefix(_x_) vDbgPrintExWithPrefix _x_
#define KdBreakPoint() DbgBreakPoint() 

#define KdBreakPointWithStatus(s) DbgBreakPointWithStatus(s)

#else 

#define KdPrint(_x_)
#define KdPrintEx(_x_) 
#define vKdPrintEx(_x_)
#define vKdPrintExWithPrefix(_x_)
#define KdBreakPoint() 

#define KdBreakPointWithStatus(s)

#endif // DBG wudfwdm

这意味着，如果使用 Release 配置进行编译(不会定义DBG宏)，则KdPrint不会发生任何事情.

This means that if you are compiling with Release configuration (DBG macro will not be defined), nothing will happen to KdPrint.

所以这不是DbgView问题.

So it's not a DbgView problem.
