firmware assigned instance number of the PCI
device that can help in understanding the firmware
intended order of the PCI device.
What: /sys/bus/pci/devices/.../d3cold_allowed
Date: July 2012
Contact: Huang Ying <ying.huang@intel.com>
Description:
d3cold_allowed is bit to control whether the corresponding PCI
device can be put into D3Cold state. If it is cleared, the
device will never be put into D3Cold state. If it is set, the
device may be put into D3Cold state if other requirements are
satisfied too. Reading this attribute will show the current
value of d3cold_allowed bit. Writing this attribute will set
the value of d3cold_allowed bit.
