    - HELP: How to debug "stuck IRPS" in TDI filter Hi Our product contains TDI filter and File system filter driver. Lately, several applications began to stuck with no known reason. I think that one of our filters causes some of the IRPS to "get stuck" so the user mode process isn't getting a response to its request and it gets stuck too. These are the symptoms: -Two computers that sometimes have their telnet application stuck when it tries to disconnect. -One computer had it's excel stuck. I don't know if excel is creating some kind of communication so I don't know if the problem is in the TDI or the file system filter. -One computer that runs AutoIt (a QA helper app). The AutoIt got stuck and afterwards all iexplore, msnm, and outlook got stuck (the application window is freeze after I run it). The wired thing is, that mozilla firefox runs OK! All the problems occurred after SEVERAL DAYS of work while our product was running. Because most of the problems were in communications apps, we think it's the TDI filter. Any idea how to debug such a problem? Is there a way to get all the stuck IRPS for a process or a driver? (Maybe doing a manual dump and get it from there?) Thanks for any help.

    - Serial Joystick Hello Group I'm new in driver development. And must admit that this is realy complicated for me :). My problem is like that: I have a joystick that use the serial port. My goal is to write a "driver" that use this serial port but acts like a joystick which is selectable in the game controller dialog. I've found out that I need the sermouse and the vhdmini example to to that. But could what are the steps that I have to do. Or is there any example code anywhere? I hope you guys could help me. thanks Tag: How to set the uninstall order of drivers with DIFxApp? Tag: 81829

    - Strange difference between XP and win2k driver Hi, Im am currently "porting" a XP driver to Win2k and during the process i got stuk on a wierd problem when trying to read from the USB. The USB device chip is a ftdi um245R. When reading from it in XP, that works ok i do: UsbBuildInterruptOrBulkTransferRequest( &current->dUrb, sizeof(_URB_BULK_OR_INTERRUPT_TRANSFER), pdx->myPipe, &buffer->data, NULL, pdx->bufferChunkSize, USBD_TRANSFER_DIRECTION_IN | USBD_SHORT_TRANSFER_OK, NULL ); KeInitializeEvent(&current->dEvent, NotificationEvent, FALSE); current->dIrp = IoBuildDeviceIoControlRequest( IOCTL_INTERNAL_USB_SUBMIT_URB, // IoControlCode pdx->LowerDeviceObject, // DeviceObject NULL, 0, NULL, 0, TRUE, &current->dEvent, // Event &current->dIostatus // IoStatusBlock ); if (!current->dIrp) { KdPrint((DRIVERNAME " - Unable to allocate IRP for sending URB\n")); goto endThread; } stack = IoGetNextIrpStackLocation(current->dIrp); stack->Parameters.Others.Argument1 = (PVOID) &current->dUrb; status = IoCallDriver(pdx->LowerDeviceObject, current->dIrp); KdPrint((DRIVERNAME " - IoCallDriver 1 returned: %8.8X\n",status)); This works fine in XP, status returned from IoCallDriver is 0x103. But when i do the same thing in Win2k i get a status of 0xC000000D which in my test application translates to ERROR_INVALID_PARAMETER. The test application is exactly the same code in xp and win2k. Can someone please help me with this, i have no clue on why it behaves like this since i believe that this is the correct syntax of doing a read.

    - SDIO: Is cmd53 tested with sdbus driver in XP, SP2 for block mode Hi, I'm doing sdio driver on XP SP2. This SDIO driver is compiled using 2003 SP1 ddk. SDIO card is coming up properly and i could do several operations using CMD52 (read/write etc). I have not enabled the interrupts yet. Now, i'm trying the CMD53. CMD53 works fine in byte mode. That is BlockMode in SD_RW_EXTENDED_ARGUMENT is set to 0 and the parameters in SDCMD_DESCRIPTOR set to SDTT_SINGLE_BLOCK and SDRT_5. But when i try the SDTT_MULTI_BLOCK mode, the command sent on the bus is not proper. I captured the CMD53 on the bus using LA, and this is what i found. My block size set was 4 bytes. I was trying to read/write 8 bytes so that two blocks of transaction should happen. But all the time, the CMD53 on the bus had 8 as Block Count. After i did some different exercise, i found that the Parameters.DeviceCommand.Length is sent as block count for CMD53 instead of .u.bits.Count in SD_RW_EXTENDED_ARGUMENT. (I made sure that the Block Mode in SD_RW_EXTENDED_ARGUMENT is set to 1 so that even on the bus i see the same for cmd53. I do not see any response from the SDIO card for this and also, the bus driver is returning back, 0xC0000185 or 0x80000011.. My sdio card supports block mode (the card capability reg- 0x08 of cccr reads 0x1F .....) Is the bus driver in XP SP2 tested with CMD53 block mode (or SDTT_MULTI_BLOCK) ? I have attached the CMD53 function i've written, along with this mail... Please let me know if there is any problem. Eliyas, please help !

    - Which miniport created \Device\HardDisk%d? I'm working on a Windows diskless boot solution (using SRP over an Infiniband adapter) and I need to know on behalf of which miniport each \Device\HardDisk%d device object was created. This is so that I can distinguish the Disk device objects that were created on behalf of my SRP SCSI miniport from those corresponding to local hard drives. This lets me choose the proper partition to mount the boot volume from. I know how to get the device objects for each \Device\HardDisk%d, but I don't know how to tell which SCSI (or whatever) miniport discovered the physical drive that the object represents. Any advice would be appreciated. Rob Netzer System Fabric Works, Inc. rob@systemfabricworks.com Tag: How to set the uninstall order of drivers with DIFxApp? Tag: 81790

    - Cache Coherency In an earlier post[1], Stephan Wolf says "On x86, there is no need to take care of any caching issues at all because x86 always guarantees cache coherency." I may be taking him too literally, but I don't see how that can be true. I've got a PCI adapter using a PLX 9030 that presents a 1K memory buffer at PCI BAR4 which is marked as cacheable to the OS. This is mapped in at DriverLoad using MmMapIoSpace() with MmCached. Once the OS is done transferring data out of the buffer, the buffer is released back to the adapter to refill with incoming data. When the memory is done refilling, the adapter hands ownership of the memory back to the OS and an interrupt is asserted. The problem I'm trying to address is how to ensure the CPU reloads its internal cache with the new data since I can see no way that it can be aware of the changes. The PLX 9030 is a target only device, so it can't master a special cycle on to the system bus. And I didn't see any way the CPU could snoop the memory for changes. The natural (and documented) way to keep the cache coherent is to call KeFlushIoBuffers() in the IRQ DPC before reading the buffer. But, as Stephan mentions, and as I've confirmed, this is completely macrolized away for x86 builds. It doesn't do anything. I haven't seen any HAL'd abstractions in the MmXxx() or KeXxx() routines that invalidate specific cache lines, so I think I'm being forced to get a little closer to the metal. It looks like the right thing to do would be to issue an CLFLUSH[2] op sandwiched between two MFENCE ops. But, that's pretty brute force, and I'm not sure these are supported by AMD. At least I couldn't find a definitive reference. If they definitely are, or if there's a different way to flush a cache line on AMD, let me know. Of course, WBINVD will work, but that flushes the whole cache to system memory, and all I need to make coherent is a tiny chunk that's <1K. Mighty inefficient. Another alternative would be to issue an INVLPG, but that seems to get all over the Memory Manager's business. If this were the right way, it would probably be better to MmUnmapIoSpace() and then re-map them. <gack> Hopefully this wasn't too newb. I've looked around the net and here for answer, so fire away! -Mark [1] http://groups.google.com/group/microsoft.public.development.device.drivers/browse_frm/thread/7b6104ea25dfcebb/351bc138b87e61b1?q=cache+flush&rnum=4#351bc138b87e61b1 [2] Sure wish there was a MmFlushCache(base, size, read_not_write) call. Wait! There's KeFlushIoBuffers() now. :-/ Tag: How to set the uninstall order of drivers with DIFxApp? Tag: 81778

    - Two filters in one AVStream driver Hello, All. I'm working on AVStream minidriver. And I want to create minidriver that will provides DirectShow filter to the user mode application all time while device is connected to the system and another one filter type that will be seen by system only then my device is switched in special state (looking at hardware state). And another one requirement is that these filers have different category (I mean category like "Video Capture source"). In AVStream documentation I have found two ways to implement additional filter type from same device. The first one is to implement two filter factories in one minidriver and to create filters of each type separately from driver. Does system notifies appications about new filters arrival in this case? Does there is possibility to point system that these filters have different categories (capture and decode, for example). The second way is to create AVStream child device. But it is not clear for me what driver will serves this child device. Please help me to clear these questions.

    - Video-Capture Card Device Driver ?? 1. I want to write a device driver for a PCI video-capture card And in ddk docs related topics are : Kernel-Streming AVStream Minidrivers Streaming Minidrivers Audio Drivers Video Capture Drivers USB Camera Drivers DVD Minidrivers Broadcast Driver Architecture Drivers AV/C Client Drivers in WHDC pages it says , KS is a former model of AVStream vs. vs.. But KS is still in ddk docs For the moment , can you guide me about my video-capture-driver challenge , KS or AVS ? What about selecting framework -> streaming-mini, filter-centric or pin-centric ?? And also what about AV/C Client drivers , do i need to write it ?? (Other resources will make me very happy , if available for streaming... ) 2. DDK Docs say : "Audio/Video streaming (AVStream) client minidrivers (Microsoft® DirectX® 8.0, Microsoft® Windows® XP and later versions of the operating system) are typically written in C++. " Why typically C++ ? Is it a must or an advice for good coding or anything related with DirectX ? 3. What about needed minimum hardware knowledge for this project , what must i know about my video-capture card to write it's driver ? /* If anyone could provide any suggestions or insight, I'd be very appreciative. */ Tag: How to set the uninstall order of drivers with DIFxApp?

    - Setting DefaultInputSlot in a PPD? Hello all, I build print drivers with the PostScript OEM customization tools, and I'm stuck on some driver/PPD interaction. The second tab in DocumentProperties is normally Paper/Quality, with two drop downs for Paper Source and Media. These are populated from the PPD via InputSlot and MediaType sections. The problem is that the PPD parser (or some other component) does not honor the DefaultInputSlot and DefaultMediaType directives, and it does its own thing. I'm using the German version, and the phrase "Automatisch Auswahlen" ("Automatically Select") is filled in for us. This phrase does not appear in the PPD, but does appear in PS5UI.DLL's resource section. This all means that we're not able to set a reasonable default, and this is causing us some real problems for a customer implementation. If we change the default in the UI, it "sticks", but we don't have portable access to the DEVMODE to muck with it ourselves. Looking in the MSDN docs: http://msdn.microsoft.com/library/en-us/print_d/hh/Print_d/pscript_34563439-cd1f-4418-b51d-a3250e35df28.xml.asp It seems clear that InputSlot is being handled specially, and it suggests to me that DefaultInputSlot is simply ignored entirely. Looking at the IPrintOemDriverPS::DrvGetDriverSetting helper function, it seems that I'm able to *fetch* values, and IPrintCorePS2 lets me enumerate them, but I think I cannot find any mechanism to *set* these options. Is there any way I can set a default value for this field when the driver is installed without requiring the user to click a box after install?

    - I2C slave device address Hi all, I am in a very strange situation for the I2C bus slave device address manipulation. Basically I have some slave devices which I communicate over the I2C bus. They work fine on different machines with Intel motherboard. The problem arises when I connect a specific slave device to the Intel 82865G machine. The address I am sending over the I2C bus for the slave device is not acknowledged by the device. The same address is acknowledged by the device on another intel machine. According to the I2C specs, the slave device is supposed to send the acknowledgement when Master finsishes sending the Bits of the address byte by pulling the SDA line low. But in this case the slave device is not pulling the SDA data line low. I have tried many cases.. like increasing the delay between the SCL , SDA check, checking the video memory, assigning the different address. But nothing is working. I am not sure whats the difference between I2C bus on one motherboard and that of another. Both are Intel 82865G. I communicate with the I2C in a driver for a graphics cards and for Intel I directly get the Video memory, convert it to the Physical memory and write to the DDC registers. I am able to send the Start condition on the I2C bus , but when I send the address of the Slave device , its not acknowledging. Other slave devices of Same type work fine. It will be very helpfull If somebody can tell me whats going on over the I2C bus for this. Thanks. -- Abhijit. Tag: How to set the uninstall order of drivers with DIFxApp? Tag: 81752

    - 1394 peripheral device identifcation (1) My driver is similar to 1394diag.sys which installs above Microsoft 1394 stack in Windows 2000/XP. This is unsigned driver. DeviceID for 1394 peripheral device is 1394\VendorName&ModelName. All my peripheral devices use same VendorName and ModelName. Still when a new peripheral device is connected, Windows 2000 and XP comes up with "New Hardware found" wizard. How can I avoid this? I donâ??t mind if I get warning "unsigned driver", but I canâ??t install driver again and again. Is driver signing required here to stop Windows prompting for driver for different EUID? DeviceId is same for all my 1394 devices and EUID is unique. What is the meaning of DeviceId if EUID is considered for DeviceId. (2) Is there any auto install method for driver to 1394 peripheral devices? I am looking for a way to have unique driver installed once for VendorName and ModelName. I know there are some topics in newsgroup. But what I dont understand is document clearly states driver for device is identified by VendorName and modelName. Documentation doesnot say driver has to be installed for every device if driver is unsigned. It only says driver installation will give "Unsigned driver" warning. So I am not sure if this is happening because driver is not signed or is it because of some other error/option in my own installation. (3) I didnâ??t see any driver signing document for peripheral drivers to 1394, found only 1394 bus drivers documentation. Thanks, Raj Tag: How to set the uninstall order of drivers with DIFxApp?

    - WHQL, HCT, WHDC, Windows Logo, Driver signing WHQL, HCT, WHDC, Windows Logo, designed for windows, Driver signing.....are these all same. Is windows logo requirement and driver signing are same? I am not able to find how to get my driver signed. This is 1394 driver for peripheral device. This driver is on top of Microsoft 1394 stack and is designed in the lines of 1394diag.sys. All I can find is 1394 bus driver or 1394 hardware. I cant see any mention of 1394 peripheral driver. I dont understand why 1394 peripheral link is not even refered from 1394 bus driver. Someone please refer the link. After Microsft arm twisted me into driver signing with otherwise crappy driver installation, I dont find proper information on this. Thanks.

    - MmMapIoSpace what exactly it does? MmMapIoSpace This function maps the specified physical address range to nonpaged process-dependent address space, providing a directly mapped virtual address to the device. Internally what exactly happens behing this API call. How does translation of address occurs?? suppose i have address dedicated for LCD controller or any other peripheral. In my driver i call MmMapIoSpace to access the device.. How will the processor know this address is meant for that particular device?? Or how does transaltion of address happens? Any suggestion is appreciated. Thanks Vijay PIC ,Bangalore Tag: How to set the uninstall order of drivers with DIFxApp? Tag: 81423

    - Conflicting errors code with USB Bulk requests When our USB function driver is used in a loop or for a long transfer of data (MBs)on a Bulk endpoint, after a short period of time the I/O status (IRP) returns a failure but the URB status is successful. This is after hundreds of successful requests. The IRP errors have been STATUS_IO_DEVICE_ERROR or STATUS_IO_TIMEOUT. The URB status is USBD_STATUS_SUCCESS in either case. In what conditions would the Windows USB stack return these errors and the URB be successful? Second question, when testing for IRP error codes from a IOCTL_INTERNAL_USB_SUBMIT_URB request, which I/O status should be tested? IO_STATUS_BLOCK ioStatus = { 0, 0 }; PIRP irp = IoBuildDeviceIoControlRequest(...., &ioStatus); // Boilerplate code... ntStatus = IoCallDriver(pdx->lowerDeviceObject, irp); if (ntStatus == STATUS_PENDING) // Wait on event At this point is io.Status.Status == irp->IoStatus.Status ???? If not, which is the proper method?? Thanks, SteveB, MCSD Welch Allyn, Inc. Tag: How to set the uninstall order of drivers with DIFxApp? Tag: 81400

    - Does the stream device have the recived/send buffer?If yes,where does it define? Hi All, When I write the MC8051 program,there is buffer to recive or send the date in the UART communication.And if there is date recived we can read the buffer directly instead of reading the bit one by one according to the timing graph. However,Does the WinCE driver program have the same mechanism as MC8051? If yes ,generally where is the buffer defined?Is it a register? For example,the driver of the AC97 ,...\WINCE420\PUBLIC\COMMON\OAK\DRIVERS\WAVEDEV\UNIFIED\ENSONIQ\ How does the chip read the media file and render?Is it one bit by one bit,or read the buffer?

    - TDI Client vs Winsock A few questions on TDI clients that someone may be able to answer: 1. In general, should there be appreciable differences in TDI client vs. Winsock throughput and latency over LAN or wireless links? 2. Does Winsock implement SO_SNDBUF/SO_RECVBUF sizes in afd.sys or in other components? That is does a TDI Client have to reimplement buffering or is it just an option passed to tcpip.sys (like TCP_NODELAY). 3. Can TDI clients issue more than 1 send irp at once? How would that affect throughput/fairness? Thanks. Tag: How to set the uninstall order of drivers with DIFxApp? Tag: 81013

I've created an installation package with InstallShield 11.5 for Windows.

It installs four different drivers using "ready made" DIFxApp functions ie.
the device driver wizard of InstallShield. One of the drivers is the parent
driver for all the remaining three drivers. The installation works fine, but
when I have to uninstall the drivers there is a problem: I should be able to
tell the order in which the drivers are uninstalled.

Is there a possibility to tell the DIFxApp the order in which the drivers
should be uninstalled? I did not found any solution to this in InstallShield
help, so I wanted to ask if anybody has already had to figure this out.
