    - what is being passed into KSDEVICE_DISPATCH dispatch functions Hi, for KS miniDriver KSDEVICE_DISPATCH maintains a list of functions pointers, We put the address of our functions, (for example AddDevice, PnPStart) into these pointers, In our definitions for these functions (AddDevice, PnPStart), there are IN parameters, what are these parameter? Where do i get this informations for these parameter? for example, for AddDevice functions, it is const KSDEVICE_DISPATCH CaptureDeviceDispatch = { MyCaptureDevice::MyDevice_PnPAdd ... } MyCaptureDevice::MyDevice_PnPAdd(IN KSDEVICE device){ } I what exactly is "device" being passed in? where can i find a better reference than the API reference on these? -- -------------------------------------------- William Tag: !srb Tag: 99987

    - Capturing with Amcap and AVStream driver My AVStream driver is having problems with capturing when using AMCap. I can see the preview with no problems, but when I start capturing, the resulting file only has one frame in it. I've gone back and tested the avshws sample and it is doing the same thing as well. Is there something missing to support capturing video? Thanks, Matt Tag: !srb Tag: 99974

    - I need valid drive letters... Hi. I need driver letter and the order.. Look at this. (this is my HDDs) Disk1 C: - '\Device\HardDiskVolume1' E: - '\Device\HardDiskVolume2' F: - '\Device\HardDiskVolume3' G: - '\Device\HardDiskVolume4' Disk3 Y: - '\Device\HardDiskVolume9' H: - '\Device\HardDiskVolume8' I: - '\Device\HardDiskVolume7' J: - '\Device\HardDiskVolume6' K: - '\Device\HardDiskVolume5' D: - '\Device\HardDiskVolume10' I can get HardDiskVolumes by disk letter (like C:\ D:\) Now I read NTFS Partition table. But I don't know how I get partition table's drive letter. In case I read Partition table, Disk1's order is valid. So I can know C, E, F, G But Disk3's order is not valid. (just desc..) So I cann't read disk letter by volume order. How can I get disk letter when I read partition table(NTFS)? Tag: !srb Tag: 99901

    - Question about WdfRequestCompleteWithInformation Hello, I have a wait queue in my IODeviceControl to wait for interrupt happen. When I need to wait, I will forward my IOCTL request to the queue, when interrupt happen, in DPC, I retrieve the request, and call: WdfRequestCompleteWithInformation(request, STATUS_SUCCESS, outputBufferLenght); to complete request. My application is C++ with Java native interface. I found that if I call above function with outputBufferLenght, Exception will happen in Java object which is If I call above function with 0 lenght, everything is OK except I didn't get my return data from IOCTL. My I/O type is buffered, my buffer is not big, about 48 bytes. My question is what above function did to my output buffer in two cases? How come it cause Java exception? Thanks, May Tag: !srb Tag: 99899

    - Legacy driver WHQL signing If this is posted in this wrong place, I apologize in advance. I work for a very small company and we have some interest in getting a 2004 era web cam driver signed by WHQL. We use it through direct show. The driver was originally signed but we have modified the .inf file to change the Manufacturer, VendorID, and ProductID. Is it going to be possible to get it signed by WHQL? We don't have the source code for the driver and we have a hard time getting any attention from the company that wrote the driver. The driver also does not work well under Vista. Our target population changes there hardware very very slowly so we anticipate at least five more years of working under XP. Does anyone have any advice? Can anyone recommend a consultant? Thanks in advance, Lars Tag: !srb Tag: 99897

    - PCI-e interrupt latency & number of interrputs limitations Hello All, May be no one here knows a correct answer for such a close hardware related issues, but this piece of knowledge may be very useful for other driver developers. In one of my previous posts I wrote about a PCI devices, located behind PCI-to-PCI-e Bridge, the topic is located here http://groups.google.com/group/microsoft.public.development.device.drivers/browse_thread/thread/3c71820bb5e5b463/9fb6213ca87b9dc7#9fb6213ca87b9dc7. Drilling down to the root of the problem I discovered very strange behavior. It seems PCI-to-PCI-e Bridge limits number of interrupts it actually translates to the PCI-e hierarchy Root Complex. In my case I got about 64 interrupts per second in total from all the secondary PCI bus devices. I have checked PCI-to-PCI-e Bridges from two manufacturers - Texas and PLX Technology - both shown very similar picture with very minor deviations in details. No wonder I can not work in a regular way with devices on the secondary PCI bus! Does any one know about such limitations and the reason they exist? With best regards, Vladimir S. Mirgorodsky Tag: !srb Tag: 99881

    - IRP_MN_REMOVE not getting called Hi, I have a typical problem of IRP_MN_REMOVE not getting called. The scenario is like this. We have a virtual USB bus which creates PDOs for each simulated device. We could simulate a mass storage device. We can 'unplug' it (from an application) by means of our bus driver sending IoInvalidateDeviceRelations and then reporting the device as missing. We subsequently get REMOVE_DEVICE for the PDO and it successfully unloads. However when we are copying some data to the device, if we 'unplug' it while still copy is in progress then we don't get the IRP_MN_REMOVE_DEVICE from the PNP manager. We see that there are no pending requests (IRPs) with us and we have successfully completed IRP_MN_SURPRISE_REMOVAL, still there is no REMOVE. After dumping the devobj I get the following trace : 0: kd> !devobj 852fe9f0 Device object (852fe9f0) is for: 00000089 \Driver\VUSB DriverObject 854cc858 Current Irp 00000000 RefCount 0 Type 0000002a Flags 00003040 Dacl e2430954 DevExt 852feaa8 DevObjExt 852fec08 DevNode 85538ee8 ExtensionFlags (0x00000008) DOE_REMOVE_PROCESSED AttachedDevice (Upper) 8527b030 \Driver\USBSTOR Device queue is not busy. This tells that there are no open references as well. I am also doubtful about "DOE_REMOVE_PROCESSED". Does this mean that system thinks that it has sent me IRP_MN_REMOVE_DEVICE ?? Any hints please? Thanks, Regards, Abhijit Tag: !srb Tag: 99865

    - OID_802_3_CURRENTADDRESS Vs OID_802_3_PERMANENTADDRESS Hi All, When NDIS calls OID_802_3_PERMANENTADDRESS ? And if it gets a valid MAC address what makes it to call a OID_802_3_CURRENTADDRESS ?? Does it mean a NIC driver can change its MAC address on the FLY... If so how can NDIS be informed about the same.... One more query, if i change the Routing table entries dynamically will this reflect in NDIS calling the Miniport adapter with OID_802_3_Currentaddress??? Can a change in the Routing table trigger a call to OIDs related to MAC address?? Thanks in advance bisban Tag: !srb Tag: 99852

    - Preinstalling Driver with DIFxApp I want to install a signed USB driver with WIX 2 and DIFxApp. This works as long as the USB device is connected to the PC during installation. If no device is connected DIFxApp does not report an error and adds an entry to Add/Remove Programs. But when I connect the device Windows can't find the driver and asks for the *inf file. The log reports the following: DIFXAPP: INFO: No matching devices found in INF "foo.inf" on the Machine. DIFXAPP: INFO: No drivers installed. No devices found that match driver(s) contained in 'foo.inf'. DIFXAPP: SUCCESS:Installation completed with code 0xE000020B. So what can I do to preinstall a driver with DIFxApp?

    - KeStackAttachProcess Hello. I have written a driver routine that changes its thread context to make a quick read of RAM from another process. As the topic here suggests, it uses KeStackAttachProcess(), performs the quick read, and leaves with KeUnstackDetachProcess(). It is generally stableâ??I am not trying to read kernel RAM or anything dangerous so I donâ??t get any blue screens, but if the target process closes while my thread is over there my application deadlocks so hard it can not be closed by any means but a reboot. Is there any sure way to prevent this? I tried using CLI and STI but then I get blue screens whining about privilege levels. I use KeLowerIrql( DISPATCH_LEVEL ) but I get the same error anyway (I thought DISPATCH_LEVEL could always use CLI?). I think I could reduce the chances of this deadlock (currently at 94%â??if the target closes, my application WILL deadlock) using PsGetProcessExitProcessCalled() and then aborting if TRUE, but then I think this is only reduces the chances, not eliminates them. What if the process is closed after I call that function but before I go into it with KeStackAttachProcess()? Is there any way to get a brief lock that absolutely ensures the process cannot close while I am there? Thank you. P. S.: I call ObReferenceObjectByHandle() before going into the target process. This is supposed to raise the reference count on the process so it canâ??t fully close, which should have been preventing my problem. Am I being mislead? Tag: !srb Tag: 99820

    - Filter driver on 64 bit OSes Hi there, I just have finished up my filter driver writting on 32bit WinXP and Vista. The next thing I am currently doing is porting this filter driver to 64 bit OSes. I have this filter driver built with "Win XP 64 bit build Envirnoment" and it ended up these drivers neither work on XP nor Vista. From the registry, I can tell that the filter driver service has been loaded up but I can't see any my debug message print out from my driver. I have been searching on net and forums but nothing useful except this thing called "Kernel-Mode Code Signing". I start to suspect that my filter driver does not work mostly because of this so-called "code-signing policy". Does anyone can tell me am I on the right track? Many thanks in advance.

    - How to identify whether a function pointer is valid? My USB driver sends Irp to query USB_BUS_INTERFACE_USBDI_V1 from bus driver. It returns STATUS_SUCCESS and fills the structure. I use USB_BUS_INTERFACE_USBDI_V1.IsDeviceHighSpeed() to query the device running speed mode. However, the IsDeviceHighSpeed() function pointer is invalid and not NULL. The system crashes immediately after the driver call the function pointer. The USB EHCI driver is 3rd party driver. I'm not surprised. I want to know how the kernel driver to identify whether the function pointer is valid before it calls the function pointer. Or how the kernel driver handle this kind of case.

    - SAA7134 & Texas XIO PCI-e-2-PCI bridge Hello All, I have a board with PCI-e-2-PCI Bridge XIO2000 from Texas and four SAA7134 Philips codecs behind it. Windows XP SP2 sees all four devices as being connected to some PCI bus. I have developed a driver for SAA7134 Philips codec and loaded it for all four devices behind this PCI-e bridge. I tested the driver with Philips devices on conventional PCI bus - it worked in the way I expected it. Everything changed with this new board. I have tons of mysterious errors. Trying to access one device memory mapped registers I affect register settings of another device on the same bus. I miss critical interrupts with almost enormous lag. Almost everything broke. My driver is conventional WDM. It uses memory mapped registers and interrupts line. SAA7134 performs bus master scatter-gather DMA video data transfer. So, here is the question - are there any special things about developing drivers for devices, connected to PCI-e bus? With best regards, Vladimir S. Mirgorodsky Tag: !srb Tag: 99761

    - Accessing disabled SCSI devices via Storport I am developing the SCSI device test application. It is intended mainly for SCSI device firmware developers and testers, and allows user to execute manually any SCSI command for the selected SCSI device. During the development and testing of the firmware the device might not be able to answer properly to SCSI commands. In this case it is necessary to disable the device object in the Device Manger window. Disabling the device object prevents the class driver from sending the SCSI commands for normal functioning. The special pseudo class driver was developed for the transparent device access. This driver sends IRP_MJ_SCSI IRPs with the SRBs directly to storage adapter objects (Scsi0:, Scsi1:, etc). This worked fine with SCSI Port but does not work with Storport. As I have learned from this newsgroup the Storport does not allow sending SRBs directly to adapter object. Sending SRBs to SCSI device object works fine but when the device is disabled there is no device object at all. The SCSI PASS THROUGH interface also does not work through the Storport for the disabled SCSI device. Is there a way to send the SCSI command to the disabled SCSI device via the Storport? Thanks a lot for advice. Tag: !srb Tag: 99759

    - How user wait for kernel? Hello, I am a new comer. I have a question: My user application need to wait for kernel interrupt and than do something. I think I will pass the request to kernel throught IOCTL call and wait for return. My kernel IOCTL function call KeWaitForSingleObject When interrupt happen, in ISR DPC, I will call KeSetEvent than my IOCTL function will return to user. Is this a good way to implement this? If not, what is the best way? Thanks, Xinshou Tag: !srb Tag: 99696

    - delreg section in INF not truly deleting registry entry I have a heisenbug I could use help on. I have service that creates several registry keys. The service has an associated INF file which has a DefaultUninstall section which is called by our product's installer when removing the service. The DefaultUninstall section calls out a delreg section which deletes about 20 keys from the registry. All but one of these keys gets deleted correctly. Now for the heisenberg portion of the bug. The installer prompts the user for a reboot at then end of the removal process. If I pull up regedit before saying yes to the reboot, the key in question is indeed not in the registry any longer and is not when the system comes back from reboot. If I do not pull up regedit and just reboot, the key is still present when the system comes back from reboot. Obviously, regedit is causing the change to be permanent in some way. Is there some lazy write problem here? Is there a way from the INF I can flush or commit the reg changes? Thanks. Bill M. Tag: !srb Tag: 99688

    - Verifier doesn't catch IRQL violation I accidentally called ZwReadFile at APC_LEVEL IRQL (holding a fast mutex actually) in a driver running on Vista RTM and got a weird result. ZwReadFile just wouldn't return. No crash, no bad status return, the thread just hung. Then of course the application was stuck with an open handle and neither the app or the driver could die properly. I turned on DriverVerifier for my driver with all options selected except low resource simulation and it never complained. It seems 1) ZwReadFile should be checking the current IRQL and returning a bad status if it isn't PASSIVE_LEVEL and 2) DriverVerifier should have caught this no? Just FYI to any MSFT folks that might care. I caught it pretty fast on my own, but this could cause someone no end of pain if they didn't know what to look for. Btw, this driver ran fine on XP SP2...don't know if that was (bad) luck or just a change in under arching operation. Haven't tried SDV on it yet. Bill M. Tag: !srb Tag: 99684

    - KeDelayExecutionThread not waiting Hi, why is this not waiting at all, there is no delay: LARGE_INTEGER x; NTSTATUS y; x.QuadPart = 100000000I64; // wait 10 seconds y = KeDelayExecutionThread( KernelMode, FALSE, &x); Here, y == STATUS_SUCCESS meaning the wait was completed, but it was not, and IRQL == PASSIVE_LEVEL.

    - Language Monitor I wrote a language monitor for our custom made printers. It reads the status of the printer every 30 seconds and flag if there is a problem with the printer. Everything works fine, we can install different printers and it works. The problem is when I reboot my PC, only the first installed printer is seen by the language Monitor. I can see all the printers in the "Printers and Faxes" window, but only the first one that was installed is polled by the language monitor. I started our language monitor from the pjlmon example from WINDDK. -- Mario Tag: !srb Tag: 99677

    - Vista does not allow config space reads beyond 0xFF I have verified in winDBG in pci!PciExternalReadDeviceConfig that it checks the offset and verifies that the aligned offset is below 0x100. If it is at or above 0x100 then the returning status is 0xC0000010 or STATUS_INVALID_DEVICE_REQUEST which is exactly what I am getting. This is contrary to msdn documentation http://msdn2.microsoft.com/En-US/library/aa906253.aspx that says extended config space access is allowed: "Drivers can read from the extended PCI device configuration space (that is, more than 256 bytes of configuration data) using the IRP_MN_READ_CONFIG request or the GetBusData method of BUS_INTERFACE_STANDARD" Please tell me that I am wrong! I really would rather not calculate the offset from 0xe0000000 (using bus, dev, func) and manually read physical memory at that location to get to the extended config space. I WANT to use OS calls! Thanks. Gabe Tag: !srb Tag: 99670

    - Ethernet driver buffer allocation This may not be the proper spot to post, but I figured it was a good starting point. I also suspect this may be dependent upon the actual Ethernet device driver, and not an industry standard. That being said: When data is transferred across an Ethernet connection using, say a TCP-IP socket connection, the end caller issues a receive call, and passes in a pointer to a buffer where the data is written. My question is: a) Is the data being transferred ONLY written into that buffer which is passed in, or b) is there an intermediate buffer contained w/in the driver to store the data as it is transferred across the medium (and then copied into the buffer passed in on the receive call)? I am trying to minimize copies in my code, because I have large amounts of data being transferred. Again, I realize that this may be totally dependent upon the ethernet card being used, I just was curious if there was an industry standard, or some underlying protocol/handshaking to which I was not aware of. Thanks. Tag: !srb Tag: 99669

    - Getting started modifying a NT serial card driver to run on XP Hello I have the source code to a driver that works fine on NT4 but we now need to get it to work on XP. Our testing indicates that the driver does not work on XP. It is possible that it is a configuration issue however - as the driver gets some data from the registry - I am checking if we have that correctly configured. But I am guessing that is not the problem. Should a driver written for NT4 work on XP without change? The driver is for an RS422 multidrop card. Are there any areas of the driver code which I should be watching out for? Is this a total re-write situation or only minor changes? Any comments would be much appreciated. Angus Tag: !srb Tag: 99666

    - Can't get reading extended config space to work on Vista I am pretty sure that the BIOS is allowing Vista to take control of PCIe since in WinDBG I can do a !pci 0x101 3 0 0 (my device is on bus 3, dev 0, func 0): ..[Config Space 0x00-0xFF omitted]... Enhanced Capabilities: 100: CapID 0002 Virtual Channel Capability Version 1 NextPtr 800 800: CapID 0001 Advanced Error Reporting Capability Version 1 NextPtr 000 However on another machine running Vista where I'm pretty sure the BIOS does not do the _OSC method and I think it is verified when I run !pci 0x101 on the same device there will be no "Enhanced Capabilities listing at all. Neither of the two Microsoft sanctioned ways (that I am aware of (i.e. GetBusData and IRP_MN_READ_CONFIG)) to access extended config space worked for me. I have even used the example verbatim from http://msdn2.microsoft.com/en-us/library/ms795302.aspx. The status returned from the IRP_MN_READ_CONFIG method is STATUS_INVALID_DEVICE_REQUEST. I've even tried installing Vista SP1 Beta, but the results are the same. Any other venues I should take/investigate? Thank you in advance. Gabe Tag: !srb Tag: 99663

Hi there

Is the !srb extension supposed to work for storport drivers?
The same question about SCSIkd.dll and Minipkd.dll extensions

TIA
