Adding custom kernel IOCTL

Hi.
I try to read MSR from GPIO driver. As I understand, I can't use
NKrdmsr function outside the OAL. So I have to implement the custom
kernel IOCTL. How do I add this IOCTL to my project?

P.S.
I work with Windows CE 5.

Thank you in advance.
Leon

you have to define the new IOCTL (Take a look at
%_WINCEROOT%\PUBLIC\COMMON\OAK\INC\pkfuncs.h to see how to define
a custom IOCTL_HAL) , write the IOCTL handler and add a new entry to
g_oalIoCtlTable in your BSP globals.c file
