20.500.12556/DKUM-14570 GONILNIK ZA NAPRAVO PCI V OKNIH DEVICE DRIVER FOR PCI IN WINDOWS Opisali smo zgradbo in delovanje jedra operacijskega sistema okna NT s poudarkom na V/I sistemu. Preučili smo vodilo PCI in naprave PCI. Za ciljno napravo PCI smo napisali gonilnik v modelu WDM. Napravo in gonilnik smo najprej funkcionalno preizkusili, nato pa smo gonilnik preverili z orodji za analizo jedrnih gonilnikov. Naš gonilnik je preizkuse uspešno prestal. Z jedrnim profilirnikom smo izdelali profil našega gonilnika. Izkazalo se je, da je časovno najzahtevnejša rutina za branje iz V/I vrat, v celoti pa gonilnik zase potrebuje okoli 0,26 % procesorskega časa jedra. Na koncu smo se ukvarjali še s čiščenjem jedra operacijskega sistema. Firstly, structure and operation of a Windows NT kernel, with an emphasis on I/O system, has been described. We studied the PCI bus and PCI devices. A device driver for the target PCI device has been written in the WDM model. The device and the driver have been functionally tested, and then the driver has been verified using tools for verification of kernel drivers. Our driver successfully passed the verification process. Using a kernel profiler, a profile of our driver has been made. It turned out that the most time consuming routine was reading from I/O port, and that driver itself consumed about 0.26% of CPU kernel time. Finally, we used a kernel debugger to clean up the source code of our driver. gonilniki operacijski sistemi naprave PCI WDM WDK preverjanje gonilnikov profiliranje jedra očiščevalnik jedra drivers operating systems PCI devices WDM WDK driver verifying kernel profiling kernel debugger true true false [J.
