pci_get_slot - locate PCI device for a given PCI slot
struct pci_dev * pci_get_slot(struct pci_bus * bus, unsigned int devfn);
PCI bus on which desired PCI device resides
encodes number of PCI slot in which the desired PCI device resides and the logical device number within that slot in case of
Given a PCI bus and slot/function number, the desired PCI device is located in the list of PCI devices. If the device is found, its
reference count is increased and this function returns a pointer to its data structure. The caller must decrement the reference count by

pcitweak -r PCI-ID [-b|-h] offset
pcitweak -w PCI-ID [-b|-h] offset value
Pcitweak is a utility that can be used to examine or change registers in the PCI configuration space. On most platforms pcitweak can only
be run by the root user.
OPTIONS -l Probe the PCI buses and print a line for each detected device. Each line contains the bus location (bus:device:function), chip
vendor/device, card (subsystem) vendor/card, revision, class and header type. All values printed are in hexadecimal.
Read the PCI configuration space register at offset for the PCI device at bus location PCI-ID. PCI-ID should be given in the form
bus:device:function, with each value in hexadecimal. By default, a 32-bit register is read.
Write value to the PCI configuration space register at offset for the PCI device at bus location PCI-ID. PCI-ID should be given in
the form bus:device:function, with each value in hexadecimal. By default, a 32-bit register is written.
-b Read or write an 8-bit value (byte).
