Virtual storport miniport driver problem

NTFSD
1

Hi,

I am working on a virtual storport miniport driver. For developing this
I have gone through the I2O code as reference.
but I am facing problem with this. My HwInitialize routin has not been
called for some reason.

Can anyone help me to resolve this problem? Can someone please provide
me the sample virtual storport miniport driver code?

Regards,
Bhavin

You are getting called at *HwStorFindAdapter* but not at *HwStorInitialize*
*?*

Generally this would be because you have failed to convince storport that
you have enough of a device to continue with. Of course storport virtual
miniports are for all practical purposes undocumented in the WDK.

There is better documenation than the woeful stuff in the WDK here online at
MSDN: http://msdn.microsoft.com/en-us/library/bb986556.aspx

In particular you appear to have to support *VirtualHwStorFindAdapter.*
Wouldn’t a sample driver be nice? Somebody should pay me to write one :slight_smile:
Here is my clue: provide a VIRTUAL_HW_INITIALIZATION_DATA object instead of
a HW_INITIALIZATION_DATA object in your call to StorPortInitialize. Just a
guess on my part.

Hi,

Thanks for link to the documentation. But I have already refer it and
also I am using the VIRTUAL_HW_INITIALIZATION_DATA object instead
HW_INITIALIZATION_DATA object. in a call to StorPortInitialize. Still I
am facing this problem. Actually I am confusing with the
PORT_CONFIGURATION_INFORMATION structure. Which values should be set to
all elements?

plz help me to do this. Currently I am setting following elements:
ConfigInfo->Length =
sizeof(PORT_CONFIGURATION_INFORMATION);
ConfigInfo->MaximumTransferLength = 0x10000;
ConfigInfo->NumberOfPhysicalBreaks = 17;
ConfigInfo->NumberOfBuses = 1;
ConfigInfo->MaximumNumberOfTargets = 1;
ConfigInfo->CachesData = FALSE;
ConfigInfo->VirtualDevice = TRUE;
ConfigInfo->InitiatorBusId[0] = 7;
ConfigInfo->ScatterGather = TRUE;

Thanks,
Bhavin

Hey,

I am also writing Storport virtual miniport. I don’t have any problem. What
OS you are using? If you are using WS2003, you have to install a KB. I
haven’t to tried on WS2008.

all the best.

I think he ment Knowledge Base update for StorPort.

Nope. Here is the KB you need for windows 2003.
http://support.microsoft.com/?kbid=943295 This storport supports storport
virtual miniport. I am not working on vista. By reading your email, I can
conlcude that your HwFindAdapter function is getting called. You can try
these things for debugging purpose.

  1. Just return SP_RETURN_FOUND in HwFindAdapter and see whether you
    HwInitialize getting called.
  2. I don’t see Master information getting filled in
    your PORT_CONFIGURATION_INFORMATION. Assign to TRUE and see whether it makes
    the difference.

all the best

What is the need in Master in a virtual miniport?

It should be unnecessary. (Just to find out that whether it makes any
difference. To work with Storport driver, the adapter must be bus master. I
don’t know OP’s environment.)

Hi Mark,

Hi,

ThankYou very much for showing interest. I am extremely sorry for
mailing you on your personal ID. But I really need your help. I am
developing Virtual Miniport Driver. As you mentioned that you are also
writing the same driver, I am looking for your kind help.

These are the some settings I did in my VMiniport driver.

DriverEntry:

VhwInitializationData.SpecificLuExtensionSize = 0;
VhwInitializationData.AdapterInterfaceType = Internal;
VhwInitializationData.TaggedQueuing = TRUE;
VhwInitializationData.AutoRequestSense = TRUE;
VhwInitializationData.ReceiveEvent = TRUE;
VhwInitializationData.AutoRequestSense = TRUE;
VhwInitializationData.MultipleRequestPerLu = TRUE;
VhwInitializationData.MapBuffers =
STOR_MAP_NON_READ_WRITE_BUFFERS;

FindAdapter:

ConfigInfo->MaximumTransferLength = 0x10000;
ConfigInfo->NumberOfPhysicalBreaks = 17;
ConfigInfo->NumberOfBuses = 1;
ConfigInfo->MaximumNumberOfTargets = 1;
ConfigInfo->CachesData = FALSE;
ConfigInfo->VirtualDevice = TRUE;
ConfigInfo->InitiatorBusId[0] = 7;
ConfigInfo->ScatterGather = TRUE;
ConfigInfo->Master = TRUE;

I am using Windows Vista(SP1). and I have following problems.

I have tried (one by one)
VhwInitializationData.MapBuffers = STOR_MAP_NO_BUFFERS,
VhwInitializationData.MapBuffers = STOR_MAP_ALL_BUFFERS, and
VhwInitializationData.MapBuffers = STOR_MAP_NON_READ_WRITE_BUFFERS

But irrespective of any settings for MapBuffers, Initially I got
Srb->DataBuffer = and SGList = NULL. I
could read and write on/from the requested blocks.

However, after some read writes, I got Srb->DataBuffer = NULL and SGList
= NULL.

I tried to get original MDL using StorPortGetOriginalMdl() which returns
an Mdl that has
Mdl->StartVa = 0x00000000, Mdl->MappedSystemVa = 0x00000000,
Mdl->MdlFlags = -30650, Mdl->ByteCount = 0x1000

What could be the reason for this behaviour? Why I am getting DataBuffer
= NULL and Mdl->StartVa = NULL ?
I just need the Virtual Address for data given in SRB and I hope
Srb->DataBuffer is a virtual address of data buffer that I want. Is
there any other way to do this ?

Please help.

Thanks & Regards,
Bhavin
