PCITWEAK(1) General Commands Manual PCITWEAK(1)NAMEpcitweak - read/write PCI config spaceSYNOPSISpcitweak -l pcitweak -r PCI-ID [-b|-h] offset pcitweak -w PCI-ID [-b|-h] offset valueDESCRIPTIONPcitweak 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. -r PCI-ID 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. -w PCI-ID 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). -h Read or write a 16-bit value (halfword).SEE ALSOscanpci(1)AUTHORSDavid Dawes (dawes@xfree86.org).
