In one embodiment, a method for controlling PCIe devices on an autonomous driving system (ADS) of an autonomous driving vehicle (ADV) is disclosed. The method includes scanning PCIe ports of the ADS to discover PCIe device(s) mounted on the ADS. Next, a comparison is performed between a list of the discovered PCIe device(s) and an expected list of PCIe devices for the ADS. Next, an offline PCIe device is determined based on the comparison, the offline PCIe device corresponding to a PCIe device that is present in the expected list of PCIe devices but not in the list of the discovered PCIe devices. Then a device reset command is transmitted to a programmable logic device that manages power for PCIe devices of the ADS to reset the offline PCIe device, wherein the programmable logic device generates a reset control signal for the offline PCIe device to reset the PCIe device.

Peripheral component interconnect express device reset for autonomous driving systems

An autonomous driving vehicle (ADV) includes a computer network that includes at least one wireless gateway. The ADV also includes a plurality of network components coupled to the computer network, the plurality of network components including a target device. The ADV also includes a processor, configured to receive, through the at least one wireless gateway, a firmware to be installed on the target device, and to direct the firmware to the target device through a first network path of the computer network. In response to detecting a failure to update the target device with the firmware, the processor directs the firmware to the target device through a second network path of the computer network.

Firmware over-the-air (FOTA) failure reduction for autonomous driving vehicle

A data processing system of an autonomous driving vehicle (ADV) may include a central processing unit (CPU) and a graphics processing unit (GPU). The CPU may be configured to monitor a behavior of a graphics processing unit (GPU), operate the GPU to perform a randomly controlled operation using a random number generator, operate the GPU to perform an idle period, and operate the GPU to repeat the randomly controlled operation. The idle period may be performed between each repetition of the randomly controlled operation, and each repetition may utilize the random number generator.
