Description

pcieutil checks the sysfs entry to conclude if a pcie device is present or not. The sysfs entry won't be updated for non-hotplug pcie device if say, a downstream port of a pcie switch (to which a pcie device is connected) receives a "hot-reset". In this case the pcie device will be disconnected from the bus, but sysfs entry doesn't reflect the missing device.
