    - Deserialized miniport question Hi, I am leveraging a deserialized miniport driver that hooks into the NDIS library. The driver is written in WDM format, not in WDF, and the OS is Windows XP The miniport driver hooks into the Windows TCP/IP stack and uses my hardware driver to send and receive data across the physical medium. The hardware is a PCIe Non-transparent bridge. I have successfully connected on a HARDWARE level, and am able to transfer data back and forth between the processors' exposed memory. Consider: Processor A = Windows XP = miniport Driver. Processor B = other side of the NTB PCIe chip. Processor A boots first, and establishes the connections as far as it can. When Processor B boots, it sends a GRATUITOUS ARP to Processor A through my hardware and miniport driver. 1) From what I can tell, the ARP comes across from B to A, and I can see it in Wireshark when I monitor my adapter. HOWEVER, the ARP information does not get logged into the ARP table, even when I â??preloadâ?? the table with the IP and a bogus Physical Address. I was expecting the Physical Address to get updated with the GRATUITOUS ARP, but it doesnâ??t. 2) Data from the GRATUITOUS ARP is passed up to the Windows stack via a call to NDISMIndicateReceivePacket() in my minport driver, and I can see my MiniportReturnPacket() function get called to release the packet. 3) Next, when I try to â??pingâ?? Processor B from Processor A, I can see the ping request come across into Processor B, and then see B respond back to A. I see the data come through into the miniport driver, but it all hangs when NdisMIndicateReceivePacket() is called. There is no Blue screen of Death, but it might as well, because it all hangs. It BEHAVES as if the system is locked on a spin lock, but I donâ??t think that is it. I can comment in and out the NdisMIndicateReceivePacket( ) to change behavior. The OOB data packet status is set to: NDIS_SET_PACKET_STATUS(RecvPacket, NDIS_STATUS_SUCCESS); Prior to calling NdisMIndicateReceivePacket(). I am looking for ideas on what to look into as possible suspects. Does anyone have any thoughts? Thanks, Jan Tag: Asyc Call Of MiniportProcessSGList Tag: 105480

    - USB 2.0 Streaming MPEG - Best way to queue request? We have a USB 2.0 device that outputs small multiples of MPEG2 TS packets(188 bytes), and therefore need to queue up multiple BULK requests to the USB bus driver(USBD) in order to keep the MPEG2 video flowing without dropping packets. Since in BULK mode our requests are not aligned on 512 byte boundaries, submitting a large buffer to the USBD does not help, since in BULK mode a transaction of less than 512 bytes ends the session. So the question is: What is the best way to queue up multiple BULK requests with small buffers in the driver? Are System Work Items a way to go, queue up multiple initially, then requeue in the callback? The DDK docs indicate that the System thread pool is a shared resource and should be used sparingly... Any suggestions would be appreciated. Thanks -decoder Tag: Asyc Call Of MiniportProcessSGList Tag: 105477

    - DPInst.exe encounters PnP Manager busy With Windows XP SP2, following is my installation experience using DPInsta.exe v2.1.0.0: 1. With deceive attached during installation, the DPInst.log reports, "PnP Manager busy, waiting until it processed the pending install events". And the driver won't be installed if the 'Found New Hardware Wizard' is not dismissed manually. How to fix the issue to allow auto installation without user intervention? 2. After preinstall the device driver, the XP machine still pops up the 'Found New hardware Wizard' for the device which requires user to search for the driver that has been pre-installed in the system. How to avoid the pops up after preinstall? Tag: Asyc Call Of MiniportProcessSGList Tag: 105470

    - custom page size and dmPaperLength/dmPaperWidth If in Microsoft Word's "Page Setup" dialog I select custom page size and enter 1.5 inch width by 1 inch high, how does this information get passed to the printer driver? I expected that the DEVMODE passed to DrvEnablePDEV would contain the correct dmPaperLength and dmPaperWidth, but these values seem to be the default form size for the printer. I set a breakpoint at DrvEnablePDEV and inspected every DEVMODE passed to the driver. All of them contained the default page size as set in the "Printing Preferences" property pages. Several of the calls showed the DEVMODE dmFields did have DM_PAPERLENGTH and DM_PAPERWIDTH set, but the values for those fields were still the default for the printer. I know these values are available because another vendor's printer driver works correctly in this case. What am I missing? Neal Tag: Asyc Call Of MiniportProcessSGList Tag: 105452

    - BthPort - How do I get the connection? I notice that there are a series of Bluetooth functions that talk to and return a handle to BthPort. I need something like "\\?\BthPort" that I can call from another driver. Unfortunately MS made all the control calls only callable from another device driver (IRP_MJ_INTERNAL_DEVICE_CONTROL) and not from the App layer so I need to write a relay driver to call SCO. I see that BthPen, BthModem, BthEnum, and BthUSB have calls. What is the exported device name for BthPort? Thanks, -Erik Tag: Asyc Call Of MiniportProcessSGList Tag: 105442

    - Filtering the I/O requests sent by non-system applications in a file HI, I'm a newbie in the world of drivers. I'm developing a file system filter driver that needs to process all I/O requests sent in by user mode applications eg; MS Word, Excel etc; I don't want to do any sort of processing on IRPs generated on behalf of the Windows OS itself ( I'm not sure I'm using the correct words here :) ). To put it simple, I want to distinguish between IRPs generated on behalf of the OS processes and those generated on behalf of user mode applications. Could anybode tell me the easiest mechanism to achieve this? Thanks in advance, Shaji. Tag: Asyc Call Of MiniportProcessSGList Tag: 105429

    - STORAGE-0012: Separated Cache Solution WHQL test I have a question about the Separated Cache Solution WHQL test. =46rom the language contained within, it seems the STORAGE-0012 test suite is defined to be more or less a stand-alone set of requirements that is self-contained from the perspective of not having a dependency on any other STORAGE-XXXX tests except STORAGE-0005 (except if a separate flash disk device is exposed in which case the device must be logo=92d separately as well). Barring the separately-exposed device case mentioned immediately above, it appears in particular that a STORAGE-0012 =93storage adapter=94 does not imply/include a requirement to meet all STORAGE-002 (Storage host controllers and adapters) requirements For one thing, it seems that if that was the intention, it would have been explicitly mentioned as that is the convention throughout the Windows Hardware Logo Program Requirements document. if anybody could give us an opinion on the relationship or non- relationship of STORAGE-0002 to STORAGE-0012, it would be most greatly appreciated.

    - returning DCR_HALFTONE from DrvDitherColor What does it mean to return DCR_HALFTONE from my printer drivers DrvDitherColor function? The DDK states that the return value should be "DCR_HALFTONE if the engine should create a halftone approximation for the driver." I return DCR_HALFTONE but this seems to have zero effect on the use of gray or colored brushes used by applications when drawing into my printer DC. In most cases, anything that is not white is printed as black. For example, black text on a gray background prints as a black block. Also, the following is from the comments section of the DDK documentation for DrvDither Color. What the heck does this mean? "Monochrome device drivers, including most raster printers, should use the iMode parameter to tell GDI how to get good gray-scale patterns." I don't understand. The "iMode" parameter is passed to my driver. What does that statement mean "to tell the GDI" ??? Tag: Asyc Call Of MiniportProcessSGList Tag: 105415

    - PnP device recognition Hi. i have a question regarding the PnP mechanism. my driver (WDF based) controls a pci board. my system can have between one to ten boards on its backplane. my question is - is there a way for me to know (to be sure) that PnP have finished dealing with all of my boards (that are related to my driver) in a given moment. my user mode side of the system needs to know weather there are still boards that were not handled by the PnP. a possible soulution might be using some kind of configuration, meaning that the user mode will have to know how many boards exist on a given system and will be able to query the driver of how many boards were found in a given moment. but since i try to avoid this kind of solution i would to know if the OS/pnp mechanism can help me with that. thanks a ot, kobi.

The problem appears not always but very often. It always lies on the boundary of two pages. Usually first or first two pages are visible properly but third, fourth and next pages are totally wrong. The table is static and allocated in driver so it is for sure NONPAGED memory. Is it a problem with Virtual Translation Table at user space side? Why, in spite of usage ZwMapViewOfSection which maps 20480, third, fourth and following pages are not visible form user application? Tag: Asyc Call Of MiniportProcessSGList Tag: 105392

    - read from virtual comport Hi, I have a program that writes/reads a virtual comport. Writing is ok. Reading always returns 0 bytes. (the connected device is sending stuff continuously) The read uses standard windows API, CreateFile / ReadFile. Commtimeouts are set. I tried every combination of options for the above mentioned functions. Hyperterminal & teraterm DO receive data from this port. A Hid-code-sample I have opens the port in the same way I do. Any idea's ? Greetings, Rob. Tag: Asyc Call Of MiniportProcessSGList Tag: 105376

    - Unable to Pend IRP on ISO Read (IN) pipe I need to pend an IRP on the ISO IN pipe with a completion routine, which will get invoked when the driver below (USB) has some data on the pipe. My problem is that i have been unable to pend an IRP (Created using IoAllocateIrp) on the ISO read (IN) pipe. I have tried with the sample provided in DDK (\WinDDK\6000\src\usb\isousb\sys) as well as the sample provided by Walter Oney (\Samples\Chap12\usbiso\sys). I am using the alternate setting number 5 provide by my device on interface 1, wherein the maximum packet size is 0x33 (51) bytes. Whenever i call to IoCallDriver to send the IRP to the next driver below, i get a failure with code 0xC000000D(STATUS_INVALID_PARAMETER). If at all the call returns STATUS_PENDING, the completion routine for the sub IRP's is getting called. Any help in this regard will be great. Thanks in advance.

    - Linking a dll or a lib file developped in C++ using Visual Studio Hello, I'm programming a virtual miniport driver that has to redirect every network packets to a windows service. To use this service, I need to link my driver with a library that was originally developped with Visual Studio 2003 in C++ language. My driver is written in C language. But when I try to use functions from the DLL, even functions that do not include classes, the build command gives me this error : Linking Executable - objchk_wlh_x86\i386\netvmini.sys errors in directory d:\projets\test d:\projets\test\netvmini.obj : error LNK2019: unresolved external symbol _InstallService@0 referenced in function _DriverEntry@8 d:\projets\test\objchk_wlh_x86\i386\netvmini.sys : error LNK1120: 1 unresolved externals Is it possible to link my driver with this library or do I need to redevelop it in C language ? thanks.

    - 32-bit HANDLE in 64-bit driver Hi, I had used following technique in communication user-mode app <--> driver: User app passes event handle to driver and driver retrieves pointer to object body with help of ObReferenceObjectByHandle() . Driver then signals some events to user mode application with KeSetEvent(). Problem is: Currently I have 32-bit user mode app which communicates with 64-bit driver. When 64-bit driver reads 32-bit HANDLE (32-bit number) passes from user-mode, can it simple make conversion like: HANDLE h64Bit = NULL; h64Bit = (HANDLE)h32BitFromUserMode; ? Will be retrieved handle in 64-bit driver valid and can be on such called KeSetEvent() in 64-bit driver ? Peter Tag: Asyc Call Of MiniportProcessSGList Tag: 105363

    - Need assistance with DPinst Hi, I am working on the automation of the driver install for a USB connected device. I don't have any experience with driver install, and hope that I can get some help from this forum. The device connects with USB and only has a .inf file. The driver itself is usbscan.sys. Currently when the device is connected a 'new hardware device detected' wizards pops up. To install it, we now have to follow a manual process. In the manual process I get a warning that the driver is not signed. I would like to automate this with a installer. I think that DPInst is the tool I could use for this. See below the data of the .inf file. I have tried the DPInst with the legacy mode argument (/lm) and then is says that the driver is installed, but it does not appear in the hardware manager. I am testing the installation on a Windows XP machine.

    - Crash dump User account pain I am using Windows Vista business edition 32-bit for driver development. When system crashes, memory dump file is created. But I cannot open it with my windbg. I have to go and add my user account by going to file properties. I tried to move dump file to another directory thinking that may make it easy. But it always creates file without any permission for me to open from windbg. I have to always go and add my user account. How can skip this step? Is there a way to tell Vista to create with permission to my account which is administrator (but cant do anything). Thanks, Raj Tag: Asyc Call Of MiniportProcessSGList Tag: 105328

    - Error 8020: Error Reading Comm Device Hi All, I have developed a USB-Serial driver. For this i have used KMDF osrusbfx2 and serial samples. I m using RS232-analyzer application for testing. This can be downloaded at http://www.232analyzer.com/CommFront-Downloads.htm. I have attached a loopback connector to the NULL modem cable and used this applcation for sending/receiving ascii data. I get the error Number 8020 and message that followed is "Error reading comm device". I have debugged the driver and i see that driver is able to write and then read the data. But the application does not receive the data. I googled the intertet for the error and found the following url. http://support.microsoft.com/default.aspx?scid=kb;en-us;318784. The resolution mentioned is "A serial driver should return SUCCESS synchronously for all read requests that can be immediately fulfilled with data that is currently present". My question is the serial EvtIoRead is a void callback function, so how can i make it to return SUCCESS? One other thing i observed is i have replaced the serial inbox drivers with the serial sample provided in KMDF. I have built the serial sample and replaced it. The same error occurs with standard COM port as well. This error does not happen with WDM serial driver. Is this a bug in KMDF serial sample driver? All above tests are done in Windows XP 32 bit OS. All your suggestions are appreciable. Thanks in Advance. Regards, madhukar Tag: Asyc Call Of MiniportProcessSGList Tag: 105322

    - 1394 camera suspend/resume Hello I am trying to debug a 1394 driver (source available here http://www-2.cs.cmu.edu/~iwan/1394/downloads/index.html). This driver is intended for cameras which are DCAM compliant. When performing an hibernation with a camera connected, a blue screen occurs at resume. I looked at the sample driver in the DDK (1394vdev) and it seems that the power.c has been simply copied from the sample driver. I have been playing with windbg to debug the driver at resume and it gives the following trace: nt!RtlpBreakWithStatusInstruction nt!KiBugCheckDebugBreak+0x19 nt!KeBugCheck2+0x574 nt!KeBugCheckEx+0x1b nt!MmAccessFault+0x9a8 nt!KiTrap0E+0xd0 nt!IoBuildDeviceIoControlRequest+0xf 1394cmdr!t1394_GetGenerationCount(struct _DEVICE_OBJECT * DeviceObject = 0x00d5aeb8, struct _IRP * Irp = 0x00000000, unsigned long * GenerationCount = 0x85d5810c)+0x65 1394cmdr!t1394Cmdr_DeviceSetPowerIrpCompletion(struct _DEVICE_OBJECT * DeviceObject = 0x85d5aeb8, unsigned char MinorFunction = 0x02 '', union _POWER_STATE state = union _POWER_STATE, struct _POWER_COMPLETION_CONTEXT * PowerContext = 0x00000000, struct _IO_STATUS_BLOCK * IoStatus = 0x86430278)+0xb9 nt!PopCompleteRequestIrp+0x55 nt!IopfCompleteRequest+0xa2 1394BUS!Bus1394Power+0xd4 nt!IopfCallDriver+0x31 nt!PopPresentIrp+0x57 nt!PoCallDriver+0x195 1394cmdr!t1394Cmdr_Power(struct _DEVICE_OBJECT * DeviceObject = 0x00000001, struct _IRP * Irp = 0x86430260)+0x202 nt!IopfCallDriver+0x31 nt!PopPresentIrp+0x57 nt!PoCallDriver+0x195 nt!PoRequestPowerIrp+0x129 It seems to me that DEVICE_OBJECT pointer passed to t1394Cmdr_Power is quite likely to be incorrect (0x0000001), and quite different of the adress that was passed before hibernation.

    - KeAcquireSpinLockAtDpcLevel deadlocks MPS Hello everybody, I have written a driver for a pci data acquasition card. When testing the driver on serveral processors I got a deadlock which maybe you can enlighten me on. Construct in my driver: I use a spinlock in a datastructure in non paged memory to access the data within. This spinlock is aquired in an ioctrl to register and deregister a datachannel with the card. It also is used in a DPC that is queued from the ISR to determine the data rate of all channels currently registert. The DPC does not recurse on itself and neither do the register and deregister ioctrls. The release spinlock functions are also in the correct place. The issue: When I use a AMD X2 dual core cpu the system somtimes deadlocks on the KeAcquireSpinLockAtDpcLevel (which is located in the DPC routine). Connecting with the debugger reveals the system in trying to aquire this spinlock at both cores from a DPC and deadlocks at that point. Is this normal behaviour? I thought the spinlock should always get acquired by one of the two. That is; when an ioctrl is run they run at DISPATCH_LEVEL and if an interrupt occurs, it just queues the DPC. Which in turn is run at the end of the ioctrl (since this is the currently executing code on DISPATCH level). The DPC could only be queued once and then run on one core. That's when the system can queue another dpc and could execute it on the other core right? But I just should sit tight until it gets the spinlock... I checked the DDK and several posts on forums but they all tell me I'm doing the right thing. E.g.: http://groups.google.com/group/microsoft.public.development.device.drivers/browse_thread/thread/e585a74c3ca6d60f http://maddimax.dyndns.org/maddi/?p=15 Anyone got a clue why none of the two gets the spinlock? Thanks in advance. Wilco Tag: Asyc Call Of MiniportProcessSGList Tag: 105317

If HAL asynchronously completes the request to to create a scatter/gather
list through calls to NdisMAllocateNetBufferSGList (i.e., completes the
request outside of the context of the NDIS call), can I assume that it
serialize the completion of pending requests?

For example, if I have two requests, can I assume that request #1 will
always be completed before request #2?

Thanks!
