12.4. Create a New Kernel PlugIn Project
As indicated above , you can use DriverWizard to generate a new
Kernel PlugIn project (and a corresponding user-mode project) for your device
(recommended), or use one of the WinDriver Kernel PlugIn samples as the basis for
To successfully build a Kernel PlugIn project using MS Visual Studio, the path to
the project directory must not contain any spaces.
If you select to start your development with the KP_PCI sample,
follow these steps:
Make a copy of the WinDriver/samples/pci_diag/kp_pci directory. For example, to
create a new Kernel PlugIn project called
KP_MyDrv, copy WinDriver/samples/pci_diag/kp_pci
Change all instances of "KP_PCI" and "kp_pci", in
all the Kernel PlugIn files in your new directory, to "KP_MyDrv" and
The names of the
KP_PCI_xxx() functions in the
kp_pci.c files do not have to be changed, but the code will
be clearer if you use your selected driver name in the function names.
Change all occurrences of "KP_PCI" in file names to "kp_mydrv".
To use the shared pci_lib library API from
your Kernel PlugIn driver and user-mode application, copy the
pci_lib.c files from the
directory to your new mydrv directory. You can
change the names of the library functions to use your driver's name
(MyDrv) instead of "PCI", but note that in
this case you will also need to modify the names in all calls to these
functions from your Kernel PlugIn project and user-mode application. If you
do not copy the shared library to your new project, you will need to modify
the sample Kernel PlugIn code and replace all references to the
PCI_xxx library APIs with alternative code.
Modify the files and directory paths in the project and make files, and the
#include paths in the source files, as needed (depending on the location in
which you selected to save your new project directory).
To use the pci_diag user-mode application,
and the relevant pci_diag project, solution, or make files to your
mydrv directory, rename the files (if you wish),
and replace all "pci_diag" references in the files with your preferred
user-mode application name. To use the solution files, also replace the
references to "KP_PCI" in the files with your new Kernel PlugIn
driver, e.g., "KP_MyDrv". Then modify the sample code to implement your
desired driver functionality.
For a general description of the sample and generated Kernel PlugIn code and
its structure, see Sections 11.6.3 and 11.6.4 (respectively).
