#Linux #FOSS #FLOSS #PCI Here I am with a new series of videos. This time about GNU/Linux and PCI (Express). I want to show you, how to access PCI (Express) devices from User- and Kernelspace. Enjoy! Know let's enter kernelspace. In this video I will write a simple Linux Kernel Module to find and enable a certain PCI device and then read from its configuration space. Because PCI Express is downward compatible from a software point of view, you can use the code for a PCI Express device too!
