    - communication between wdf and wdm drivers. Hi, i have an architecture question regarding communication between a wdm driver and a wdf driver. my system holds an old wdm driver and a new WDF based driver. My product is going through a phase where these two drivers will need to communicate (until the old wdm will not be used anymore). i read some of your articles regarding driver-to-driver communication and i basically use function pointers (and interface notification for synch) and all works well. i started to face a problem when i try to do as follows : my WDF driver will be called with a pending IOCTl in order to fill some data and return it to the user mode part of that WDF driver. My WDM driver, however, is the one who's responsible for the interrupt handling. so - when an interrupt arrives, the WDM driver handles it and in its DPC will use function pointers in order to call a routine that is implemented in the WDF driver. here's where the problem starts : since the call comes from the WDM driver context i'm not able to use in that function any WDF calls. i get bug check. so my question is how would i be able to complete the pending IOCTL request in the WDF driver from a call in the WDM driver since i'm not able to use any WDF methods such as WdfCompleteRequest. does it seem right to use a work item in the WDF driver that would be signaled when the WDM driver uses the function pointer (a function that is implemented in the WDF driver which passed the function's pointer to the WDM driver) ? thanks, Kobi.

    - I/O target from socket doesn't timeout Hi, I have created an I/O target from a socket but when I send an I/O request to it, it won't timeout. The socket was created with WSASocket passing WSA_FLAG_OVERLAPPED and I used setsockopt() to set read/write timeout as below. After setting these options the I/O target is created using IWDFFileHandleTargetFactory::CreateFileHandleTarget. When I send down the request I specify a timeout of 10 seconds, but it won't work. Socket creation: socket = WSASocket(AF_INET,SOCK_STREAM,IPPROTO_TCP,NULL,0,WSA_FLAG_OVERLAPPED); Socket configuration: int iOptVal = 3000; res = setsockopt(socket, SOL_SOCKET, SO_SNDTIMEO, (char*)&iOptVal, sizeof(iOptVal)); res = setsockopt(socket, SOL_SOCKET, SO_RCVTIMEO, (char*)&iOptVal, sizeof(iOptVal)); I/O Target creation: IWDFFileHandleTargetFactory *fileHandleTargetFactory = NULL; IWDFIoTarget *target = NULL; hr = fxDevice->QueryInterface(IID_PPV_ARGS(&fileHandleTargetFactory)); hr = fileHandleTargetFactory->CreateFileHandleTarget(socket, &target); fileHandleTargetFactory->Release(); Request forwarding: request->Send(target,WDF_REQUEST_SEND_OPTION_TIMEOUT,-100000000); Has anyone had this problem? How can I set a timeout for a request sent to an I/O target created from a socket handle? Thanks in advance. Tag: How to test DMA above 4GB? Tag: 107489

    - I need a network miniredirector sample, NulMRx DDK sample doesn't Hi, I downloaded WDK 6001.18001. I built NullMRx sample and installed it. I tried it on WinXP and W2K3.. Unfortunatelly "net use * \\nulsvr\share" does not work. It returns with "System error 67 has occurred. The network name cannot be found." In init.c (Line 284) RxStartMinirdr function failed. It returns with "c000000e" (STATUS_NO_SUCH_DEVICE). I found this in the MSDN: "The call to RxStartMinirdr cannot be made from the DriverEntry routine of the network mini-redirector after a successful call to RxRegisterMinirdr since some of the start processing requires that the driver initialization be completed." But the RxStartMinirdr is called from DriverEntry. Could someone help me to solve this problem or give me a sample which works. Would be very important. Thanks, Misi. Tag: How to test DMA above 4GB?

    - Getting printer specific information stored in GPD file Hi all, Basically i have a custom UI and renderer plug-in for a printer driver using unidrv.dll. What i need to know in the plug-in are diffrent options set in the GPD file without reading(parsing) the GPD file. The only supported methods I found are in IPrintCoreHelper::GetOption which can give a feature - option return but not the particulars of that option. And the second method is IPrintCoreUI2::DrvGetDriverSetting which also given a feature name returns the selected option. The other close third is IPrintOemDriverUni::DrvGetGPDData which can only return the value of *OEMCustomData field. Is there a way to get other field from the GPD ? RM Tag: How to test DMA above 4GB?

    - DirectInput, USB HID filters, and EvtInternalDeviceControl I'm trying to write a filter for a USB HID device that will essentially override the device's HID Descriptors with a custom version, but otherwise function as a normal HID device. I've gotten the driver to compile, install, and execute but the EvtInternalDeviceControl function is never called. I've checked several of the KMDF samples and it appears I'm registering the function correctly. My EvtDeviceAdd and EvtDeviceD0Entry functions run, but nothing after. Further, will I need to do anything special in order to have DirectInput correctly recognize the device with the corrected descriptor? I'm using the hidkmdf HID minidriver KMDF sample as the function driver with this as my LowerFilter. I can post additional code and log data as needed. Below is the pertinent piece of my DeviceAdd function: WDF_IO_QUEUE_CONFIG queueConfig; WDFDEVICE hDevice; /* SNIP */ status = WdfDeviceCreate(&DeviceInit, &attributes, &hDevice); if (!NT_SUCCESS(status)) { DbgPrint("SIXCD: WdfDeviceCreate failed with status code 0x%x \n", status); return status; } WDF_IO_QUEUE_CONFIG_INIT_DEFAULT_QUEUE(&queueConfig, WdfIoQueueDispatchParallel); queueConfig.EvtIoInternalDeviceControl = SixcdEvtInternalDeviceControl; status = WdfIoQueueCreate(hDevice, &queueConfig, WDF_NO_OBJECT_ATTRIBUTES, WDF_NO_HANDLE ); if (!NT_SUCCESS (status)) { DbgPrint("SIXCD: WdfIoQueueCreate failed 0x%x\n", status); return status; } Tag: How to test DMA above 4GB?

    - DPINST - ReInstal l- scan for hardware change Hi, I am using DPINST for install & removal for the driver. To update a driver first i am removing the driver using dpinst /U inf /D and for reinstllation I have to do the hardware scan using devcon utility before installing again, otherwise, DPINST wont be able to find the device, it returns that no devices are found. Because for XP OS, with out hardware scan, installation wont be succesful, it is not the case for vista. Problem: When i do the hardware scan with devcon, Add hardware wizard comes up, i want to supress that. Question: 1) Is there any way to supress this wizard here? 2) using DPINST, before installing, is there any way to scan the device with out any pop-up coming?

I was just adding entry in the registry and copying the driver files to system directry for my installation application. Now I am planning to install it thru inf file.

    - XcvData broken on Vista I have a print driver/port monitor pair that use XcvData and XcvDataPort to communicate. When the printer is being used as a network printer and connected to by a client, the driver on the client calls XcvData with a custom string in pszDataName. My XcvDataPort function in the port monitor recognizes this string and responds with the requested data. It's very simple, fully supported according to the documentation, and works flawlessly between XP boxes. But throw Vista into the mix and it's completely broken. If the server is XP and the client is Vista, XcvData returns error 2 (file not found). The port monitor on the server is *not* called. Conversely, if the server is Vista and the client is XP, XcvData returns error 122 (insufficient buffer). And again, the port monitor on the server is not called. However, despite the fact that XcvDataPort was never called, XcvData gives me back error 2 as XcvDataPort's return code. The actual printing works flawlessly in both cases, so I know it's not a fundamental permissions or network issue. It's purely a problem with XcvData. I strongly suspect it's a security issue since most things Vista are, but even if I turn off the firewall, UAC, print as admin, set permissions on the printer to full control for everyone, etc, I get the same results. It's as if Vista is simply refusing to allow XcvData to communicate with the port monitor. Any clues? Simplified code follows to give you an idea.... On the client I do this: // open the port on the print server HANDLE hServer; if (!OpenPrinterW(L"MyServer\\,XcvPort DIRPS:", &hServer, NULL)) return false; // request the data char *pBuff = new char[dataSize]; if (!XcvData(hServer, L"GetConfigData", 0, 0, (PBYTE)pBuff, dataSize, &dataSize, &status) || status != ERROR_SUCCESS) return false; On the server, the port monitor does this: DWORD WINAPI XcvDataPort(HANDLE hXcv, LPCWSTR pszDataName, PBYTE pInputData, DWORD cbInputData, PBYTE pOutputData, DWORD cbOutputData, PDWORD pcbOutputNeeded) { if (pszDataName && !wcscmp(pszDataName, L"GetConfigData")) { *pcbOutputNeeded = dataSize; if (cbOutputData < dataSize) return ERROR_INSUFFICIENT_BUFFER; *pOutputData = myData; return ERROR_SUCCESS; } return ERROR_SUCCESS; } Tag: How to test DMA above 4GB?

    - Checked build driver with free build OS.... Hi, I know, to help debugging, its required to have the windows checked build and with checked build driver (driver under development). But what happens if checked build driver is loaded and used with free build os ? (XP SP2). As far as I know, the checked build driver 1. Does not have optimization enabled 2. Lots of DbgPrint 3. The size of the binary is huge (because of symbols and etc). 3. The driver will be slow. Are there anything more to add to the above list ? If I manage to remove all the prints and if the driver is meeting the performance criterion, is it advisable to deploy the checked build driver with free build OS ?

    - Port Monitor: referencing external libraries in sample code Hi, I am new to Driver development. I am implementing the Port monitor for our printer driver. Basically I am migrating from a previous Port Monitor( visual studio project) which implements the MONITOR structure to the recent MONITOR2 structure using the DDK environment. As can be seen, there is some similarity in the MONITOR2 and MONITOR structure and some of the existing functionality can be reused. So I planned to export the functions required by MONITOR2 from the current port monitor library and use it in the DDK sample port monitor(ddklocalmon). For this I implemented the header file for the existing Port monitor and compiled it as a static library. Added the function names to the .DEF file. I included this library in the TARGETLIBS section of the Sources file in localmon directory. Also added the path to the header file in the INCLUDES section. However when I added a call to the logerror() function in the imported library, I get the following error on linking Linking Executable - objchk_wxp_x86\i386\ddklocalmon.dll errors in directory d:\doccreator\actino\p4root\jaws\niknak\win\localmon d:\doccreator\actino\p4root\jaws\niknak\win\localmon\localmon.obj : error LNK2019: unresolved external symbol _logerror@0 referenced in function _LcmStartDocPort@20 d:\doccreator\actino\p4root\jaws\niknak\win\localmon\objchk_wxp_x86\i386\ddklocalmon.dll : error LNK1120: 1 unresolved externals Questions: 1] Can someone please let me know what could have gone wrong with this implementation.? 2] Is adding a reference to a Visual studio library to the DDK project possible? 3] Have I added the library and header file to the correct sections in the Sources file? Please let me know if you need more explaination. thanks Mangesh Tag: How to test DMA above 4GB? Tag: 107425

    - Getting SID of process owner Hi, Getting SID of user account under which a process is running can be easily done by user-mode code via WIN32 APIs: OpenProcess(), OpenProcessToken(), GetTokenInformation(TokenUser). But in device driver, if PID of a process is known, how difficult is it to get owner SID? Thanks, Boris Tag: How to test DMA above 4GB? Tag: 107424

    - Can more than 3 packets be transfered per microframe in iso? For ISO transfer, we need to send 4 of 1024 per microframe for speed needed. The protocol says that bit12-11 define the number of packets per microframe. And it can only be as many as =92b10 for 3 packets per microframe. However, in USB 2.0 spec Table 5-5 =91High-speed Isochronous Transaction Limits=92, it clearly shows that packets per microframe can be more than 3. (e.g., for 1024 bytes packet, it can be 7 ; for 64bytes packet there can even be 73 packets per microframe). Thanks Tag: How to test DMA above 4GB? Tag: 107416

    - Automate a test that has included reboots Suppose we want to add a test to a DTM suite that has one or more reboots. Outside of DTM, the test add's itself back to the registry using the RunOnce key to continue after reboot. When using DTM, what is the correct setup (i.e. does DTM restart the test application following reboot)? Currently, what I'm seeing is that if the test issues a reboot, DTM marks it as a Control-C failure. Thanks... Tag: How to test DMA above 4GB? Tag: 107414

    - Regarding "bTemporalCompression" in avshws of DDK Hello, I am developing a PCI capture driver, and I use "avshws" as sample to develp the driver. I can capture AVI with H.264 codec by AMCAP, and the avi file can play well. My problem is as following: I would like to set bTemporalCompression(in KS_DATARANGE_VIDEO) to be TRUE. Then, the captured AVI frames will be not all marked as key frame. I connect capture pin to dump filter. When I trace in avshws, bTemporalCompression is really true. But when I trace into dump filter, it shows bTemporalCompression as FALSE. In addition, in "IntersectHandler" function, the sample code doesn't copy "bTemporalCompression" and "bFixedSizeSamples" into "Data"(PKS_DATAFORMAT_VIDEOINFOHEADER). If I write following code: FormatVideoInfoHeader->DataFormat.SampleSize = 0; Then, I can see "bFixedSizeSamples" in "Dump" filter is updated to FALSE. Therefore, should I copy "bTemporalCompression" into somewhere to make the flag enable? Can somebody kindly help me to solve this problem? My data range defines as following: KS_DATARANGE_VIDEO FormatH264_Capture = { // // KSDATARANGE // { sizeof (KS_DATARANGE_VIDEO), // FormatSize 0, // Flags DMAX_X * DMAX_Y * 2, // SampleSize 0, // Reserved STATICGUIDOF (KSDATAFORMAT_TYPE_VIDEO), // aka.

    - Mirror display driver in the multimon configuration (negative origin) I'm trying to enable support of the multimonitor configurations for my mirror driver. I had modified mirror driver loading code to bind it to the properly initialized DEVMODE (dmPosition etc), so mirror driver binds to the entire virtual screen. Firstly, i had configured my test system with dual monitor in this way: |0,0----------------1024,0--------------| | M1 (primary) | M2 | | | | |0,768------------1024,768-----------| In this configuration all works fine - all gdi calls correctly mirrored to the mirror driver back buffer. Next, i tried to move M2 just before M1, so virtual display origin in X becomes negative: |(-1024,0)--------0,0------------------| | M2 | M1 (primary) | | | | |(-1024,768)----0,768---------------| At this point most of the mirrored gdi calls draws in the back surface incorrectly - as if there is no negative origin, how i can feel it. I tried to debug this - parameters to the DrvBitBlt/DrvCopyBits seems to be quite correct (all back surf coordinates mapped to the (0,0) origin). And more - blits from the back surf to the back surf (for example, when moving window) are not performed correctly. But some gdi calls, that can't use back surface as source (f.e., DrvTextOut) are performed quite well. Mirror driver is very simple: 1. DrvEnableSurface: EngCreateDeviceSurface, EngAssociateSurface. 2. DrvEscape(start): EngCreateBitmap, EngAssociateSurface, EngLockSurface. 3. All hooked DrvXxx calls back to the EngXxx, replacing surface, created at the step 1 by surface, created at the step 2. As I understand XPDM, there is no sense to the mirror driver on his origin - gdi should map coordinates by itself. Or there is a necessity of the "magical steps" to get this working all together?

    - Resource Rebalancing We are writing a WDM driver on Windows Server 2008 (64 bit) for our PCI device. Our device has a 64 bit BAR whose size is a multiple of 32GB. The BIOS doesn't enable this BAR by default and we'll have to enable it dynamically by setting a particular bit in the PCI config space. We are doing this in the AddDevice routine of our driver. Please let me know what is the procedure to get this BAR recognized by Windows. Will Resource rebalancing help solve this problem? I know that to intiate the resource rebalancing sequence, I need to call IoInvalidateDeviceState routine. But where do I call this routine from? Can somebody please help me solve this problem?

    - Standard user can not do uninstallation in control panel in Vista Hi Sir I get a problem with the DIFxAPP.msm when building an installer. The merge module comes from DIFx 2.1. We use DIFxAPP.msm to install driver in our installer. After we build the installer (Setup.exe, SPI.msi, Data1.cab) with the merge module, we login Vista 32 with an administrator account, and finish the installation with setup.exe, the driver can be installed correctly. Then we log out, and re-login as a standard user, and do uninstallation in control panel. In the uninstallation process, there will be an error and the process rolls back. Later under the standard user account we use SPI.msi do uninstallation in command line, and the process is same with that in control panel. According the log we catched from command line, the error come from custom action "UninstallDriverPackages" that comes from the DIFxApp.msm Following is the prompt information from the log. DIFXAPP: UninstallDriverPackages() DIFXAPP: 'CustomActionData' property 'DIFxApp Version' is 2.1. DIFXAPP: 'CustomActionData' property 'UI Level' is 3. DIFXAPP: 'CustomActionData' property 'componentId' is {1B113BBD-6D70-11D4-82D2-00D0B72E1DB9}. DIFXAPP: 'CustomActionData' property 'flags' is 0x7. DIFXAPP: 'CustomActionData' property 'ProductName' is Sentinel Protection Installer 7.5.0. DIFXAPP: 'CustomActionData' property 'ManufacturerName' is SafeNet, Inc.. DIFXAPP: ERROR 0x2 encountered while opening install-info subkey for component '{1B113BBD-6D70-11D4-82D2-00D0B72E1DB9}' DIFXAPP: UninstallDriverPackages failed with error 0x2 DIFXAPP: RETURN: UninstallDriverPackages() 2 (0x2) The detailed information about Vista 32 is 1. Microsoft Windows [Version 6.0.6000] 2. Windows Vista Enterprise 3. No patch installed The detailed information about merge module is 1. Come from DIFx 2.1 2. English, x86 (\DIFxApp\English\MergeMod\x86\DIFxApp.msm) If we do uninstallation under Administrator account, anything are right. Are there anyone can lend me a hand for the issue, it is a bug of DIFx or Vista OS? Any comment will do me a great help. Thanks gwei Tag: How to test DMA above 4GB? Tag: 107355

    - Query on Difference in driver behavior when printing directly to Hi Ben , I have been observing a very peculiar behavior for some Genoa applications while printing from our monolithic printer driver. If you could spare some time to give your valuable suggestions, it would be very helpful to us. Please find the details of the buggy behavior below: Difference in driver behavior when printing directly to printer compared to when printed to file A document formed using the application called LivePix Soho(from Genoa Test Suite) is printing in an erroneous way(extra lines are printed in a bitmap) when printed directly to the printer But it is printing properly when it is printed to file (choose FILE as the port and specify the file name =93test.prn=94) and the prn is fired to the printer. The document contains a 24bits per pixel (8bits each for red, blue and green) bitmap and some extra lines are printed on the right edge of the bitmap. I debugged and found that DrvStretchBlt is being called in our driver and the parameter from GDI having the source image data, psoSrc->pvScan0, has different and erroneous data when job is given to printer when compared to the data it has when job is given to file. Because of this erroneous data the extra lines are getting printed. Any inputs on the same would be greatly helpful. Thanks and Regards, Ayshwarya Mohandas Tag: How to test DMA above 4GB?

Hi all,

I have a device which support 64-bit DMA.
I would like to test this functionality but I don't know how.

I had tried /nolowmem /pae boot options but it doesn't work.
Could you give me some comment? Thanks. ^_^

Best regards,
Ziv

I think Driver Verifier on 2003 (non-Web edition) can do this.

Note that you cannot do this on XP or Vista 32. You must use a 64-bit
system, or Windows Server 2003 or 2008.

2003 other then Web Edition, Web Edition has the same truncated memory as XP.
