Accessing PCI device resources through sysfs
---------------------------------------------
+============================================
sysfs, usually mounted at /sys, provides access to PCI resources on platforms
that support it. For example, a given bus might look like this:

numbers are reproduced for convenience. Under the device directory are several
files, each with their own function.
