《Windows驱动开发技术详解》读书笔记（二）

再来看基于WDM的驱动程序，

#ifdef __cplusplus
extern " C "
{
#endif
#include < wdm.h >
#ifdef __cplusplus
}
#endif

typedef struct _DEVICE_EXTENSION
{
    PDEVICE_OBJECT fdo;
    PDEVICE_OBJECT NextStackDevice;
    UNICODE_STRING ustrDeviceName;     // 设备名
    UNICODE_STRING ustrSymLinkName;     // 符号链接名
} DEVICE_EXTENSION, * PDEVICE_EXTENSION;

#define PAGEDCODE code_seg("PAGE")
#define LOCKEDCODE code_seg()
#define INITCODE code_seg("INIT")

#define PAGEDDATA data_seg("PAGE")
#define LOCKEDDATA data_seg()
#define INITDATA data_seg("INIT")

#define arraysize(p) (sizeof(p)/sizeof((p)[0]))

NTSTATUS HelloWDMAddDevice(IN PDRIVER_OBJECT DriverObject,
                           IN PDEVICE_OBJECT PhysicalDeviceObject);
NTSTATUS HelloWDMPnp(IN PDEVICE_OBJECT fdo,
                        IN PIRP Irp);
NTSTATUS HelloWDMDispatchRoutine(IN PDEVICE_OBJECT fdo,
                                 IN PIRP Irp);
void HelloWDMUnload(IN PDRIVER_OBJECT DriverObject);

extern " C "
NTSTATUS DriverEntry(IN PDRIVER_OBJECT DriverObject,
                     IN PUNICODE_STRING RegistryPath);

HelloWDM.cpp

同前面一样，编译也是两种方式，第一种用DDK编译，准备两个脚本文件，makefile和Sources，其中Sources有所不同，如下所示：

TARGETNAME = HelloWDM
TARGETTYPE = DRIVER
DRIVERTYPE = WDM
TARGETPATH = OBJ

INCLUDES =$( BASEDIR )\ inc ;\
$( BASEDIR )\ inc \ ddk ;\

SOURCES = HelloWDM . cpp \

另一种是用VC进行编译，有三点需要注意：

1，选择c/c++选项卡，将原来的Project Options全删掉，换成下面的：

/ nologo / Gz / MLd / W3 / WX / Z7 / Od / D WIN32 = 100 / D _X86_ = 1 / D WINVER = 0x500 / D DBG = 1 / Fo " MyDriver_Check/ " / Fd " MyDriver_Check/ " / FD / c

2，选择Link选项卡，将原来的Project Options全删掉，换成下面的：

wdm . lib / nologo / base: " 0x10000 " / stack: 0x400000 , 0x1000 / entry: " DriverEntry " / subsystem :console / incremental :no / pdb: " MyDriver_Check/HelloWDM.pdb " / debug / machine :I386 / nodefaultlib / out: " MyDriver_Check/HelloWDM.sys " / pdbtype :sept / subsystem :native / driver / SECTION :INIT , D / RELEASE / IGNORE: 4078

3，修改include目录时，加入

D: \ WINDDK \ 3790.1830 \ INC \ DDK \ WDM \ W2K

否则会报错如下：

fatal error C1083: Cannot open include file: 'wdm . h': No such file or directory

最后是驱动的安装,WDM驱动的安装需要写一个inf文件，如下所示：

; --------- Version Section ---------------------------------------------------

[Version]
Signature = " $CHICAGO$ " ;
Provider = Phinecos_Device
DriverVer = 20 / 2 / 2000 , 3.0 . 0.3

; If device fits one of the standard classes , use the name and GUID here ,
; otherwise create your own device class and GUID as this example shows .

Class = PhinecosDevice
ClassGUID = {EF2962F0-0D55-4bff-B8AA-2221EE8A79B0}

; --------- SourceDiskNames and SourceDiskFiles Section -----------------------

; These sections identify source disks and files for installation . They are
; shown here as an example , but commented out .

[SourceDisksNames]
1 = " HelloWDM " , Disk1 ,,

[SourceDisksFiles]
HelloWDM . sys = 1 , MyDriver_Check ,

; --------- ClassInstall / ClassInstall32 Section -------------------------------

; Not necessary if using a standard class

; 9X Style
[ClassInstall]
Addreg = Class_AddReg

; NT Style
[ClassInstall32]
Addreg = Class_AddReg

[Class_AddReg]
HKR ,,,, %DeviceClassName%
HKR ,, Icon ,, " -5 "

; --------- DestinationDirs Section -------------------------------------------

[DestinationDirs]
YouMark_Files_Driver = 10 , System32 \ Drivers

; --------- Manufacturer and Models Sections ----------------------------------

[Manufacturer]
%MfgName% = Mfg0

[Mfg0]

; PCI hardware Ids use the form
; PCI \ VEN_aaaa&DEV_bbbb&SUBSYS_cccccccc&REV_dd
; 改成你自己的ID
%DeviceDesc% = YouMark_DDI , PCI \ VEN_9999&DEV_9999

; ---------- DDInstall Sections -----------------------------------------------
; --------- Windows 9X -----------------

; Experimentation has shown that DDInstall root names greater than 19 characters
; cause problems in Windows 98

[YouMark_DDI]
CopyFiles = YouMark_Files_Driver
AddReg = YouMark_9X_AddReg

[YouMark_9X_AddReg]
HKR ,, DevLoader ,, *ntkern
HKR ,, NTMPDriver ,, HelloWDM . sys
HKR , " Parameters " , " BreakOnEntry " , 0x00010001 , 0

; --------- Windows NT -----------------

[YouMark_DDI . NT]
CopyFiles = YouMark_Files_Driver
AddReg = YouMark_NT_AddReg

[YouMark_DDI . NT . Services]
Addservice = HelloWDM , 0x00000002 , YouMark_AddService

[YouMark_AddService]
DisplayName = %SvcDesc%
ServiceType = 1 ; SERVICE_KERNEL_DRIVER
StartType = 3 ; SERVICE_DEMAND_START
ErrorControl = 1 ; SERVICE_ERROR_NORMAL
ServiceBinary = %10 % \ System32 \ Drivers \ HelloWDM . sys

[YouMark_NT_AddReg]
HKLM , " System\CurrentControlSet\Services\HelloWDM\Parameters " ,\
" BreakOnEntry " , 0x00010001 , 0

; --------- Files ( common ) -------------

[YouMark_Files_Driver]
HelloWDM . sys

; --------- Strings Section ---------------------------------------------------

[Strings]
ProviderName = " Phinecos. "
MfgName = " Vista Soft "
DeviceDesc = " Hello World WDM! "
DeviceClassName = " Phinecos_Device "
SvcDesc = " Phinecos "

这里有两种安装方式，一种是进入“控制面板”，选择添加硬件，加载进inf文件完成安装，如图所示：

另一种可选的安装测试方式是使用Driver Studio中的EzDriverInstaller工具来进行安装，如图所示：
