Problems / Questions about Storport.sys driver

NTDEV
1

We are trying to just write a basic driver that does nothing that we can load into storport.sys correctly.

When we call StorportInitialize() we should see storport calling our FindAdapter() function but this does not happen. The SCM reports the driver is loaded successfully yet Storport does not call FindAdapter(). Any ideas. See code below.

#include “ntddk.h”
#include “storport.h”

typedef struct _DEVICE_EXTENSION
{
ULONG data;
} DEVICE_EXTENSION, *PDEVICE_EXTENSION;

typedef struct _SRB_EXTENSION
{
ULONG data;
} SRB_EXTENSION, *PSRB_EXTENSION;

NTSTATUS DriverEntry( PDRIVER_OBJECT driverObj , PUNICODE_STRING regPath )
{
VIRTUAL_HW_INITIALIZATION_DATA virtdata;
ULONG i;

virtdata.HwInitialize = vInitialize

virtdata.HwInitialize = vInitialize
virtdata.HwFindAdapter = vFindAdapter

virtdata.AdapterInterfaceType = Internal

status = StorportInitialize( driverObj, regPath, (PHW_INITIALIZATION_DATA) &virtdata, NULL );

}

You are not correctly initializing the structure. Here is what needs
to be done…

//
// Set up information for StorPortInitialize.
//
RtlZeroMemory(&OsrHwInitData,
sizeof(VIRTUAL_HW_INITIALIZATION_DATA));
OsrHwInitData.HwInitializationDataSize =
sizeof(VIRTUAL_HW_INITIALIZATION_DATA);

//
// Set up our entry points (callbacks).
//
OsrHwInitData.HwInitialize = OsrHwInitialize; //
Required.
OsrHwInitData.HwStartIo = OsrHwStartIo; //
Required.
OsrHwInitData.HwFindAdapter = OsrHwFindAdapter; //
Required.
OsrHwInitData.HwResetBus = OsrHwResetBus; //
Required.
OsrHwInitData.HwAdapterControl = OsrHwAdapterControl; //
Required.
OsrHwInitData.HwFreeAdapterResources = OsrHwFreeAdapterResources;
OsrHwInitData.HwProcessServiceRequest = OsrHwProcessServiceRequest;
OsrHwInitData.HwCompleteServiceIrp =
OsrHwCompleteServiceRequest;

OsrHwInitData.AdapterInterfaceType = Internal;

OsrHwInitData.MultipleRequestPerLu = TRUE;
OsrHwInitData.PortVersionFlags = 0;

OsrHwInitData.DeviceExtensionSize =
sizeof(HW_DEVICE_EXTENSION);
OsrHwInitData.SpecificLuExtensionSize = sizeof(HW_LU_EXTENSION);
OsrHwInitData.SrbExtensionSize = sizeof(HW_SRB_EXTENSION) +
OsrUserGetSrbExtensionSize();

status = StorPortInitialize(DriverObject,
RegistryPath,

(PHW_INITIALIZATION_DATA)&OsrHwInitData,
NULL);

if (STATUS_SUCCESS!=status) { // Port driver
said not OK?
OsrTracePrint(TRACE_LEVEL_ERROR,OSRVMINIPT_DEBUG_FUNCTRACE,
(“DriverEntry failure in call to
StorPortInitialize. status:0x%x\n”,status));
ExFreePool(OsrRegistryPath.Buffer);
ASSERT(FALSE);
return status;
}

Sorry, i was trying to post but i guess the forum didnt let me finish. Seems I can not go back and edit a post which i created…

Anywho would love thougths and ideas on why FindAdapter is not getting called as the DDK indicates that it should be getting called.

THanks

I actually have the exact code you posted except that I have sizeof(DEVICE_EXTENSION) not size of (HW_DEVICE_EXTENSION) but since you declare the struct I assume you just gave it a different name.

5

I should note that in my code i also declared InitTracing() and CleanupTracing() and storport is calling InitTracing()

6

How did you install it? Do you have real hardware?

}

retrun STATUS_SUCCESS

I load it by the (service control manager). No real hardware.

If you do not have real hw yet, have you created a root pnp device? You cannot use the osr driver loader or net start or the scm to load the driver and have it start running

YOu cannot do it that way. YOu need to have an inf file to make are
root enumerated device…

Not the right way. Look at the toaster bus driver sample on how to use devcon to create a root enumerated device and and inf for it. Note that you do not need to write your own bus driver, just learn the inf syntax and how to invoke devcon

The next NtInsider article on Virtual Miniports will document this…
