Someone have a pointer to a good technical overview, and details, of how specific locations of drivers are determined and used in these special directories?
for example, the below udevinfo command shows info from: to match the device for which the node will be created. looking at the device chain at '/sys/devices/pci0000:00/0000:00:07.0': ==== udevinfo -p /sys/class/net/eth0/ -a
and several other locations. how is the path determined? how are these numbers determined? how do programs use this information to do their thing? are these commonly known address/directories and if so how are the paths determined?
this is all darn new to me so please excuse any simple questions to you. I have been reading the kernel source and its slow going.
