Demo Program We created a short Linux utility that searches for and reports all of your system's PCI devices It's named pciprobe.cpp on our class website It uses some C++ macros that expand to Intel input/output instructions -- which normally are 'privileged' instructions that a Linux application- program is not allowed to execute (segfault!) But using 'sudo' you can escalate the privilege- level at which this utility-program will be run: $ sudo./pciprobe
