    - Test cases for WLAN SDIO interface Hi All, I am working in WLAN driver with SDIO interface. I have some refrence code of WLAN but i dont know how to test this WLAN through SDIO interface.I am very pretty new in this filed and mean to say , need some test plan to make some test cases for this driver interface. I will appreiciate if someone extend his arms. Thnaks Shivmangal Tag: How to broadcast messages to all application in co-installer entry Tag: 105571

    - Sharing COM1 with WinDbg I have an embedded device running XPe with a single serial port (also no 1394). The COM1 port is normally used by applications for other purposes. However, I would really like to be able to use this for kernel debugging as well. I tried using /crashdebug option in boot.ini so that the COM1 port does not disappear. The problem is that this does not let me debug on demand, only when a bug check occurs. Is there a way to enable on demand debugging without reserving the serial port for exclusive use by the debugger? If not, the other option would be to have WinDbg monitor for specific debug messages coming from the other machine. My understanding is that this used to be possible with a .waitforstr command, but that doesn't seem to be implemented any more. Is there a way to monitor messages from within WinDbg? Thanks!

    - IoCallDriver Bugcheck Hi, I observed a strange behavior with Intelx64 PCs with my virtual COM driver. When I pass an irp to lower driver (using IoCallDriver()) i get an Assertion Failure - code c0000420 exception and when i forcefully continue it i get a bugcheck. I get this exception when i pass the IRP with one of the vendor specific commands. Also, this exception is not happening frequently. It happens for every 3 out of 5 times. I have used an application to test the sequence. By the way this failure is not happening in either Intel x86, AMD x64 or AMD x86 bit machines. In all the PCs i have installed Vista 32-bit OS. I did not see anything pointing in my driver, but i strongly believe that some thing is going wrong in my driver. I have pasted the bugcheck code and wdflog below. Can someone help me find the bug where im going wrong? Here is the bugcheck code: *** Fatal System Error: 0x0000008e (0xC0000420,0x81828671,0x9EF97A3C,0x00000000) Break instruction exception - code 80000003 (first chance) A fatal system error has occurred.

Usually the exception address pinpoints the driver/function that caused the problem. Always note this address as well as the link date of the driver/image that contains this address. Some common problems are exception code 0x80000003. This means a hard coded breakpoint or assertion was hit, but this system was booted /NODEBUG. This is not supposed to happen as developers should never have hardcoded breakpoints in retail code, but ... If this happens, make sure a debugger gets connected, and the system is booted /DEBUG. This will let us see why this breakpoint is happening.

    - IRP Tracker I see many entries in Device Selection Menu. In that \Driver\Disk is a entry which gives the entries for all the disk in the system. My doubt is,say for a disk I see entries and I notice that a particular IOCTL IOCTL_DISK_GET_DRIVE_LAYOUT reaches only \Device\Harddisk2\DR3 in my case. what is that DR3 ,what does that mean. what are all the other entries like \Device\Harddisk2\DP(2)0X8004400 - 0XC800000+7 \Device\Harddisk2\DP(1)0X4400 - 0X8000000 + 6 can anybody explain what entry is that. why that particular IOCTL reaches \Device\Harddisk2\DR3 from the application eventhough I have filter drivers between. Thanks in advance. Hope I havent confused Tag: How to broadcast messages to all application in co-installer entry Tag: 105562

    - IOCTL_DISK_GET_DRIVE_LAYOUT doubt I have a lower filter driver(sits below file system driver) From the application I pass IOCTL_DISK_GET_DRIVE_LAYOUT ioctl. I get error as my partition style is GPT. I am not supporting GPT Partition style for now in my driver.so I wanted to log the error in system logs from the driver if it is GPT. But when I tried to log it I see that the particularIOCTL never reaches my driver. Is it possible that file system driver can return error for this IOCTL. I tried checking with irp tracker .when I select my driver and see for the occurence of the particular IOCTL I am not seeing the IOCTL. when I select the corresponding GPT disk in select disk menu I see the IOCTL that is required. Is it that the IOCTL is returned back with error code by file system driver before even my filter receives it. I also see that the error code is INVALID_DEVICE_REQUEST in IRP Tracker. I believed that disk.sys is responsible for the above IOCTL.so I expected my that IOCTL_DISK_GET_DRIVE_LAYOUT should reach my driver.But I am not sure whether my driver receives the IOCTL. Can anybody help on this. does file system driver have any specific check in it. Tag: How to broadcast messages to all application in co-installer entry Tag: 105560

I am allocating the MDL memory for 16MB. System is AMD 64-bit 2GB RAM and for other OS also, i tested in the same PC. Do i have modify any settings in vista64-PC to increase the success rate of IoAllocateMdl?

    - PC Restart required after driver unload and before installing agai Hi, I am working on a WDF PCI device driver, driver supports PNP functionality. Problem: when driver uninstalled, i had to restart the system in xp-32 & xp-64 before driver installing again, where as this is not required in vista-32 bit pc. Driver installation: I am currently using DIFX tools DpInst for installing & uninstalling the driver. I also verified that my driver unmaps the resources before uninstalling the driver using MmUnmapIoSpace to unmap the PCI memory resources. Device doesnt support power managment capability, so driver also not supporting any power managment functionality, instead it just registers the callback & wont do anything inside. Since this problem is existing only in xp, do i have to take any extra care to avoid system restart? and also, after uninstall system doesnt prompt for restart also.

    - Generating a driver without DDK,... Hi, i have a situation here which is really true. I have a old laptop, running windows 2000 professional and there is no space left for the DDK from Microsoft. I want to write and test some (simple, monolithic) drivers, targeting 2000/XP/Vista which handle a special device over USB. So the situation is that i dont have a lot of space for ddk on my machine and i am looking for a way to write a driver, compile it into a native image and all this WITHOUT the MS DDK. Is there such a way, a minimal package of compilers, headers, not bigger than 200 MB? I already have livekd and WinDbg here, but no compiler so far and no environment. The environment should be as small as possible and the compiler should be capable of inline assembly. Is something like this available somewhere? I am not kidding, i really have no space left here on the machine. This may sound funny but this is really the situation.

    - extra WHQL warnings My app calls UpdateDriverForPlugAndPlayDevices and it works. The driver is installed, the device works, everybody is happy. Except... If more than one instance of the model in question is on the bus (it's a USB device), then I get not just one WHQL warning but at least one more. And the pattern is very weird. Let's say the user plugs in one of my devices, and my app calls UpdateDriverForPlugAndPlayDevices, and the user gets a WHQL warning, and she says continue, and everything works. Peachy, right? Now she plugs in a second device and she gets two warnings. Weird! Let's say she says continue two more times and then plugs in a third device. Now she gets three warnings, but the weirdness is just getting started. She plugs in a fourth instance of the device and she gets one warning (expected) but then she plugs in a fifth instance and gets two warnings. Remember, I get the extra warnings even if all but one instance of the device in question already has the driver. But, just to be paranoid, I made sure I was not calling UpdateDriverForPlugAndPlayDevices again due to re-entrant delivery of messages to my window. Of course, I am looking to inhibit the extra WHQL warnings. Any ideas?

I need to report to the higher layers that the MTU is reduced by the size of the option header to ensure that the finished packets do not exceed the MTU. Since an outbound network layer callout can not see IP fragments, I am concerned that the packet will then be fragmented, thus invalidating the header that I applied (each option is correlated to the data in the payload). Can any of the forum gurus give me any advice? Thanks! Tag: How to broadcast messages to all application in co-installer entry Tag: 105505

    - Access violation when device plugged out I have allocated using ExAllocatePoolWithTag to allocate buffer from non paged pool for reading data through the USB AV streaming device. when the driver is streamng the data from the device, and when device is suddenly removed, I check for the URB's status for NO DEVICE after IoCall driver to the next device object. The data recieved is buffered and processed and sent to the other layer. during this time some time when the device is plugged out suddenly, it gives ACCESS VIOLATION BSOD with 0x7E, I am sure the allocated memory is not freed also, the accessed location is not out of bounds of the allocated memory area. The address is not null. Is there any way to check whether the address is valid. This happens only when the device is plugged out. and during normal operation, it works fine. There are 2 possibilities: Device present: during this time bulk transfer is done to read the data from deivce into the buffer and is further sent to processing. Device is removed: when a bulk transfer is attempted, it is programmed to return STATUS_NO_SUCH_DEVICE such that the call is returned and the buffer pointer is not sent for processing. In both the case, how does it give access violation, as the buffer is allocated and is not freed yet. Can somebody let me know if any thing I am missing.. Thanks..

    - Bug in usbser.sys when using a high speed hub I have a full speed USB device that I'm developing that uses usbser.sys. I found that if I connect the device directly to my Dell laptop everything works find. If I connect the device through a high speed USB 2.0 hub everything is very flaky. I see hangs when opening the com port, Windows lockups, and other wierd falures. I found a workaround. If I disabled the enhanced USB controller in device manager to force the hub to use full speed everything is rock solid. So this makes me think the problem is either a bug in Windows or a bug with the Intel chipset in my Dell Inspiron laptop. 1. Is this a known bug in usbser.sys or Windows? 2. What do I need to do to report the problem? My operating system is Vista SP1. Tag: How to broadcast messages to all application in co-installer entry Tag: 105484

    - Asyc Call Of MiniportProcessSGList 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!

    - 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: How to broadcast messages to all application in co-installer entry 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: How to broadcast messages to all application in co-installer entry Tag: 105477

    - 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?

    - 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: How to broadcast messages to all application in co-installer entry Tag: 105415

I hate to contradict my esteemed colleague Maxim, but there is indeed a
way to have your coinstaller broadcast a message: do it from a
finish-install action.
