    - drive verifier makes DMA impossible Dear all, Im writing a WDM driver for a PCI device doing bus master packed based DMA. The device and the driver are working well so far, until I followed the suggestion of some experts to turn on driver verifier. OK, I did that and ran into several problems (which actually was caused by my not so correct code). The most ones I could solve but there was one I couldn't get rid of: The DMA runs perfectly but the data are always 0x0E, no matter what was in my user buffer! The device is not "scatter/gather-able" so I split up the DMA transfer into several small one-page DMA transfers. The logical address determined by MapTransfer() seemed to be NOT describing my user buffer. When DMA checking of driver verifier is disabled the transfer works perfect and the logical address determined by MapTransfer() is higher (e.g. 0x0a2ed1f8), but I don't know if the address has anything to do with that problem. Thanks for help Daniel Tag: driver verifier makes DMA impossible (cont.) Tag: 53439

    - PortMonitor can't be installed Hi, Has anyone seen this behaviour? I use the Add Port to install the port monitor coming with the DDK and after the inf is pointed to monitor.inf ,nothing happens. What's happening? I had installed once the DDK portmon long time back, but can't make out why it doesn't go through this time. Thanks Tag: driver verifier makes DMA impossible (cont.) Tag: 53423

    - WinXP PRO - UPS Minidriver Dll localisation bug ? Hi, I've written an UPS minidriver Dll. When running the Dll on an english version of Windows XP Pro everything works fine. According to the DDK documentation the battery status (HKLM\System\CurrentControlSet\Services\UPS\Status\BatteryStatus) has 3 documented states (0=unknown, 1=OK, 2=replace). Looking at the UPS status display (Start\Settings\Power Options\Power Options Properties\UPS) the display shows "Good" for state 1 and "Needs replacing" for state 2. When shutting down the system because of lost AC power a messenger service dialog box pops up saying "The UPS service is starting shut down at XXX". So far so good, the DDK documentation is consistent with the user display. Running the same Minidriver Dll on a german Windows XP shows a slightly different behaviour. The UPS status display shows "Niedrig" for state 1. This means "low" - a big difference to the documentation and the english version and confusing for the user because he thinks the batteries are low. The messenger service dialog box says "Der USV Dienst beginnt, wegen geringer Batteriespannung, bei XXX mit dem Herunterfahren." This means "The UPS service is starting shut down because of low battery voltage at XXX". This is also a big difference to the english version and confusing for the user because he thinks the batteries are low. The behaviour is the same with SP1 and SP2 of the german version. Now my question : is this just a bug in the german translation of XP or are there any other side effects (internal state etc.) ? Tag: driver verifier makes DMA impossible (cont.) Tag: 53418

In other words, each time when an application writes a large chunk of data, say 2MB, I want consecutive sectors be used. Can this be done with a filter driver on top of NTFS?

    - Printer drivers and StretchDIBits calls Hello I am writing a virtual printer driver for Win XP/2000. The driver is using an engine-managed surface and is hooking all next DDI functions: - DrvBitBlt - DrvStretchBlt - DrvTransparentBlt - DrvCopyBits - DrvAlphaBlend - DrvStretchBltROP - DrvPlgBlt All these functions are tested when printing from different applications, and they work fine. But when an application is printing a bitmap using StretchDIBits function, none of the above driver functions is called. Is StrechDIBits function writing directly on the driver surface bitmap, without calling any of Drv...() functions? Is there any way I can hook this function before it is writing the bitmap on the driver surface? Thanks Luminita Tag: driver verifier makes DMA impossible (cont.) Tag: 53407

    - WinXP build environment I have installed (in this order): VC++ 6.0 Platform SDK February 2003 Windows 2000 DDK in my system (Windows XP SP1) for my build environment but it seems I messed it up.I cannot build the sample plotter driver. When I launch the checked build or free build utility, it says that there are some program or batch files that cannot be recognized. When I build the sample plotter driver, there is a U1073 error. plotlib.lib build method is not set, something like that. When I installed the SDK, I chose to automatically set the environment. Any idea on this. Thank you. Tag: driver verifier makes DMA impossible (cont.) Tag: 53395

    - WDM NIC driver causes diabling of all network properties Hi All, I have a WDM driver for W2k/XP for a NIC this **IS NOT AN NDIS DRIVER** but a normal WDM driver that allows direct access to the NIC hardware. The hardware is a 3COM 3c90x on PCI. Once the driver is installed the user is not able to change any network settings for other installed network drivers (that do use NDIS drivers). The properties of other installed network drivers is disabled. The client has to uninstall the non-NDIS WDM driver to change the network setting and then re-install. Why is this and how can I prevent it? Cheers, SAB. Tag: driver verifier makes DMA impossible (cont.) Tag: 53390

    - Dll Build I am trying to build a class installer dll and I want to use a .def file to specify the exported functions. After looking at the SDK and some DDK samples, I'm still a bit confused. How should I be building the dll: use the command line utility included with the SDK or the VC++ build enviroment? Is it just a matter of preference? I found a section in the MSDN library about how to use a .def file in the VC++ IDE, but was unable to locate the "project Property Page" to set the /DEF option. Can someone explain the steps needed to export functions in a dll using either the VC++ IDE or command line? Or point me to an article. Thank you for your time.

    - hooked functions in usermode printer driver I have a monolithic usermode printer driver (see my numerous previous question for details :) under development. It's adapted from an earlier kernel-mode printer driver. I'm trying to work out the final kinks, and I've come across some rather odd behavior. I've found that some applications have trouble printing particular shapes (diagonal lines and ellipsesfor example) on any page except the first. In the kernel-mode driver, these work fine, and in the debug output I can see calls to DrvBitBlt for each of these shapes that is drawn on the printed image. In user-mode, I don't see these calls. In fact, I don't see any of my driver code being called. Somehow these shapes make it onto the first page I print, but never the second. I am hooking DrvBitBlt, DrvCopyBits, DrvStretchBlt, DrvTextOut, DrvFillPath, DrvStrokePath, DrvStrokeAndFillPath, and DrvLineTo. How would the application get data onto the driver's surfaces? -- Matt Kane mkane@zebra.camel.com minus cigarettes Tag: driver verifier makes DMA impossible (cont.) Tag: 53373

    - WDM driver and services What are the things that one needs to consider when interacting with a user mode component( say with a service EXE) from a WDM streaming driver. Basically, the service si started before the logon and it makes an IOCTL to the driver with the necessary data. It also wants to create an Event that the driver would call whenever it needs data and waits on the event so that when the event is triggered, it does an IOCTL(KssyncrhroniseDeviceControl through a cutom property set) and then goes back into Wait mode for the event to signal. How would this be done ? Just implementing a pending IRP wont do as there are no IRP's, but SRB's and the WMD streaming driver would only interact with the Stream Class driver. Does, the WDM driver need to implement EVENT_SETS(I guess not) ? Because, in this case, the service can Create an Event and send that event handle to the WDM driver and wait on it to get into signalled state ? so if thats the right approach, what does the WDM streaming driver need to do to handle this scenario and signal the event, whenever it needs some data. Thanks. Tag: driver verifier makes DMA impossible (cont.) Tag: 53369

    - Device CoInstaller Hello, Following the toaster example in the Windows XP DDK, I have been able to make a device co-installer and have had my inf file register it properly. I am handling the DIF_ADDPROPERTYPAGE_ADVANCED event, but am unable to get my property page to show up. If I make it a class installer, I can get the page to show up (this is the specific example in the DDK, whereas I want to have it device specific). I get no errors, and everything seems to be as the DDK describes, but the page simply does not show up. Am I having the page get added to the wrong device instance (though I only have 1 enumerated)? Does anyone have any additional examples where this is being done for a device co-installer? Thanks, Abe Krebs Tag: driver verifier makes DMA impossible (cont.) Tag: 53363

    - how to notify? Hello all, From time to time I want to send some data from NDIS driver to user-mode application. How can I do it? The first thing that comes up to my mind is to create a device with NdisMRegisterDevice and query it in a loop from user-mode program. But this will take some processor resources... Are there any other ways to receive notifications from driver? What I need is a two-way pipe between driver and user-mode application. Thanks. Best regards, Serge.

    - Question on porting the USB driver from Windows 2000 to Windows 98 Hoi, I have a USB driver like this(quoted from the driver user guide, a little bit complicated): --------------------------------------------------------------- The USB host driver runs on Windows 2000 and Windows XP platforms. It simulates two types of legacy functions or devices over USB: modem and serial port. The driver accepts the following: * Single-function device â?? includes the USB modem and the simulated legacy serial port device * Composite device â?? consists of a logical modem and a logical serial port device Although the driver is designed to work with the device compliant to USB CDC 1.1 Abstract Control Model (ACM), it accepts standard USB CDC ACM descriptors as well as AAA vendor-specific descriptors. (here, AAA stands for the company name) --------------------------------------------------------------- Do you think it can be ported to Windows 98 SE without major changes(e.g., have to change the driver model from WDM to VxD)? If yes, modify the existing driver source code so that it could be compiled under 98DDK successfully, or use Walter Oney's WDMSTUB technique? which method is possible and easier?

    - How to access mapped memory from kernel driver Hello, This is probably a very simple thing, but somehow i can not find any examples on the internet dealing with direct memory access. I have embeded board that has battery backed memory - this memory is linked to ram (like video RAM) and it is located at D000:0000 (in DOS like format) I can access this memory from dos and i also can access this memory from winDriver utility and other utilities dealing with memory access from windows XP. however in my kernel driver I'm getting Access violation - code c0000005 (!!! second chance !!!) error on any attempt to acces this memory range. I have portions of my driver accessing ports - this works fine so I'm really lost here. this is what I'm doing: in driver entry: PHYSICAL_ADDRESS MemAddress; ULONG MemLength; MemAddress.HighPart = 0x00000; MemAddress.LowPart = 0x0D0000; //NVRam Base Address (d000:0000, 4 kb window) MemLength=0x1000; //4kb window ......

I also tried SetupCopyOEMInf(szInfFullPath2, NULL, SPOST_PATH, SP_COPY_REPLACEONLY, szInfNameAfterCopy, MAX_PATH, NULL, NULL) to replace the INF file and I got error code 0x80070002 Any help are apreciated, Thanks, Hannah.

    - 1394 + WinXP SP2 Hi All! Unfortunately, I'm a total newb to driver development and I have a broken driver that I have no idea whats going wrong. Its a 1394 isocronous camera driver that was developed on W2K but had been working on XP until SP2 was released. Now the driver will no longer load itself. The failure occurs on IOCallDriver which returns 0xC0120090. The error is defined as STATUS_FLOAT_INVALID_OPERATION. I can not determine what that error means. The driver is in the process of initializing an address space to receive quadlet write requests (status messages) from the camera. An isochronous channel and bandwidth has not yet been allocated at this point. Any hints or clues would be greatly appreciated! Regards, John Tag: driver verifier makes DMA impossible (cont.)

    - Where to find more detailed INF description? Hi I have the problem that I don't get usber.sys working on Windows ME. On Win2k it works, but I guess that it's more luck than knowing what exactly goes on (there are some good examples to find). The key-problem is, that the i.e. registry entries are not fully specified (what's possible in the Install section). Does anybody know where to find a more detailed information about INF files, i.e. what different registry entries are possible, or how to extract a default driver from default Windows installation CD, etc? Without additional information it will stay trial-and-error to complete the INF file - but still: how to know about existing possibilities without having a description about it? Many thanks for help Holi Tag: driver verifier makes DMA impossible (cont.) Tag: 53280

A device attached to the system is not functioning. The problem appears after HCT installation. I guess, it's Driver Verifier and SoftIce incompatibility. The deleting existing setting and reboot doesn't help!!! 1. Which driver support Driver Verifier such as I would change its Start = option? 2. Can I close Verifier to wake up SoftIce?

    - How to set up a USB driver to read an Interrupt End Point Dear Experts, I have a device with an interrupt endpoint where data can be asynchronously sent by the device. To read this data, I have followed the technic presented by Mr. Walter Oney in his book on WDM driver - setup a End Point in transaction to be always pending on the desired end point. This technic works functionally but reads data one byte by one. This is slowing down my driver. I want to setup this pending IRP to read as many bytes as are present in the EP buffer in one shot. How do I do this? Do I simply set the IRP to read multiple bytes? What will happen if the device has just one byte to be sent? Will this not keep the IRP pending till the device has as many bytes of data as requested? I do not want this to happen either - I want to read "as many bytes as present at the time of issueing this IRP" without waiting if less no. of bytes are present. Thanks for any ideas.

I thought I would start out with this problem first becausre if I need to do backups before updates. Could someone please give me some info ASAP; I'm @ my wits end!

    - Resume from suspend and USB storage driver may continue copying fi Hi, I'm writing a USB removable disk driver for WinXP. I have a problem need to help. It is: "Copy a large file from disk to a removable disk, then go to suspend (S1 or S3). After resume, it needs to finish file copy without any error messages." But the system returns error a message such as " Cannot Copy filexxxx, file system error". Anyone can help me or give suggestions. Thanks a lot. Hsiang Hua,Chao C-Media Inc.

    - How to precisely control timing write I/O to lpt with driver? can someone tell me how to precisely control timing to write I/O out to Lpt with kernel mode driver? I had compiled and modified a kernel mode parallel port driver, a user mode dll to export I/O read and write, and a MFC application that issues I/O read and write through the driver to an externel device connected to the parallel port. Everything seem like ok, but when i use QueryPerformanceCounter and QueryPerformanceFrequency api in the MFC application to obtain accurate desired timing delay (in nanosecond accuracy), the application writing out a waveform to the Lpt to the external device, may not appear as accurate as desired. Sometime the delay appear longer, though most of the time it works fine. In some computer it has such delay error appear at every particular interval. And it will not produce a desired delay when a CD or music is played at the computer. below is the source code: do{ BOOL bResult = ::QueryPerformanceCounter(&liCurrentCnt); if(liCurrentCnt.QuadPart < liBeginCnt.QuadPart) { AfxMessageBox("Error occured in timing!"); // never happen break; } }while(liCurrentCnt.QuadPart < liMaxBoundCnt.QuadPart); Is there any solution to this problem? Is there any method in kernel mode driver, that I can hog the CPU processing for a certain amount of time? Or is there any way can I put my application thread or driver service routine to the highest priority that no other software can interrupt it? Can anyone please help?
