View WPP Trace Log on Windbg

 在windbg窗口输入以下指令：

!wmitrace.start MySession -kd -ft 100ms
!wmitrace.enable MySession {你的trace-GUID}  

trace.h里会有GUID（如果你是使用VS生成的KMDF驱动模板）：

测试：

#include "driver.h"
#include "driver.tmh"

#ifdef ALLOC_PRAGMA
#pragma alloc_text (INIT, DriverEntry)
#pragma alloc_text (PAGE, EvtDriverContextCleanup)
#endif

extern "C"
NTSTATUS
DriverEntry(
	_In_ PDRIVER_OBJECT  DriverObject,
	_In_ PUNICODE_STRING RegistryPath
) {
	WPP_INIT_TRACING(DriverObject, RegistryPath);

	TraceEvents(TRACE_LEVEL_INFORMATION, TRACE_DRIVER, "%!FUNC! Entry, Build on %s at %s", __DATE__, __TIME__);

	WDF_OBJECT_ATTRIBUTES attributes;
	WDF_OBJECT_ATTRIBUTES_INIT(&attributes);
	attributes.EvtCleanupCallback = EvtDriverContextCleanup;

	WDF_DRIVER_CONFIG config;
	WDF_DRIVER_CONFIG_INIT(&config, WDF_NO_EVENT_CALLBACK);
	config.DriverInitFlags |= WdfDriverInitNoDispatchOverride;

	NTSTATUS status = WdfDriverCreate(DriverObject, RegistryPath, &attributes, &config, WDF_NO_HANDLE);
	if (!NT_SUCCESS(status)) {
		TraceEvents(TRACE_LEVEL_ERROR, TRACE_DRIVER, "WdfDriverCreate failed %!STATUS!", status);
		WPP_CLEANUP(DriverObject);
		return status;
	}

	TraceEvents(TRACE_LEVEL_INFORMATION, TRACE_DRIVER, "%!FUNC! Exit");
	return status;
}

VOID
EvtDriverContextCleanup(
	_In_ WDFOBJECT DriverObject
) {
	PAGED_CODE();
	TraceEvents(TRACE_LEVEL_INFORMATION, TRACE_DRIVER, "%!FUNC! Entry");
    WPP_CLEANUP(WdfDriverWdmGetDriverObject((WDFDRIVER)DriverObject));
}

 安装驱动（管理员权限打开终端）：

sc create mytestsample type=kernel binPath=C:\dev\驱动名.sys

sc start mytestsample
