driver

问题 We are storing allot of time series data into our own proprietary "database". In the next version of our system we want to give our users a simple query mechanism to extract the raw data from the database (as a complement to the reports our system can create) by using standard tools. I have looked at the possibility to write an ODBC driver, but it looks like quite a daunting task, especially when the use will be very simple select statements. I would be grateful for any tips, ideas and/or

问题 In Ethernet PCI device driver if the driver allows applications to map user-space buffer to Driver virtual memory and allow the user to call MMAP on device driver file after opening it. Then how do implement MMAP in the PCI ETHERNET Network device driver? I have already looked in the dev_pci struct. There are some members that are named as they have something to do with MMAP but I could not pinpoint how to make a device driver implement MMAP. In the book Linux Device Driver, the author did

问题 I am trying to write C++ code programmatically installing NDIS 6.0 lightweight filter driver. After reviewing WinDDK, online examples and MSDN documentation I ended up with the code sample below. ************** hr = InstallSpecifiedComponent( ModuleFileName, L"MS_NdisLwf", &GUID_DEVCLASS_NETSERVICE ); ************** hr = HrInstallNetComponent( pnc, lpszPnpID, pguidClass, lpszInfFile ); ************** if ( !SetupCopyOEMInfW(lpszInfFullPath, DirWithDrive, // Other files are in the same dir.as

问题 Is there any tool that I can use to load .sys driver. I just made hallo world driver from this tutorial http://www.rohitab.com/discuss/topic/24166-windows-driver-development-tutorial/ but I don't know how to load it. Cant find anything on google. 回答1: You have two choices - You have sc.exe as Harry said in his comment, or you have the OSR Loader, which is what I personally use. Keep in mind that, on Windows Vista/7 x64 you will need to use BCDEdit to enable TESTSIGNING ( bcdedit -set

问题 i want to install the drivers for u are u 4500, but it only can be compiled with old kernel versions (2.6 to 3.2) , can you help me to install the drivers on ubuntu with last kernel version. The sample application of fingerprint cant recognize the device. 回答1: I am not sure what problems you are having, but I could compile and install the driver under Ubuntu 18.04. I did get a few errors during compilation, which I fixed as follows: Error 1: /opt/DigitalPersona/urusdk-linux/Linux/drivers

问题 I run a raytracer in CUDA with N Bounces (each ray will bounce N times). I view the results using openGL. once N is small (1~4) everything works great. once i make N big (~10) each thread (about 800x1000) has to do a lot of computing and this when the screen goes black, and than back on, with the note that my nvidia crash. i searched online and think now that what cause it some sort of a watch-dog timer since i use the same graphic card for my display and my computing (computing takes more
