pci_cmd module

The pci command can enumerate PCI/PCIe devices, enumerate expansion ROMs and allow direct access to PCI configuration registers via bus/device/function.

>>> chipsec_util pci enumerate
>>> chipsec_util pci read <bus> <device> <function> <offset> [width]
>>> chipsec_util pci write <bus> <device> <function> <offset> <width> <value>
>>> chipsec_util pci dump [<bus>] [<device>] [<function>]
>>> chipsec_util pci xrom [<bus>] [<device>] [<function>] [xrom_address]
>>> chipsec_util pci cmd [mask] [class] [subclass]

Examples:

>>> chipsec_util pci enumerate
>>> chipsec_util pci read 0 0 0 0x00
>>> chipsec_util pci read 0 0 0 0x88 byte
>>> chipsec_util pci write 0 0x1F 0 0xDC 1 0x1
>>> chipsec_util pci write 0 0 0 0x98 dword 0x004E0040
>>> chipsec_util pci dump
>>> chipsec_util pci dump 0 0 0
>>> chipsec_util pci xrom
>>> chipsec_util pci xrom 3 0 0 0xFEDF0000
>>> chipsec_util pci cmd
>>> chipsec_util pci cmd 1
