The board firmware of the early PCIE driver board is updated frequently, and although the firmware can be updated, the updating operation is cumbersome and needs to be performed on site, or the service needs to be stopped first, so that the user experience is poor.

The driver chip firmware is present in an EEPROM (Electrically Erasable Programmable read only memory). The upgrading of the firmware depends on the board card contact pin, the firmware is connected with the driving chip through the board card contact pin, and then the upgrading and the maintenance of the firmware are carried out through a special tool of the driving chip. The pin of the board card needs to depend on field operation, namely the upgrading of the whole firmware depends on the field operation, the upgrading efficiency is low, the operability is poor, the time consumption of the upgrading process is long, and the firmware upgrading operation of batch machines cannot be completed in a short time.

The upgrading needs the off-shelf service of the service end, and has a large influence on the service end.

In view of this, how to optimize the firmware upgrade operation of the PCIE driver card is a technical problem to be solved by those skilled in the art.

Having described the technical solutions of the embodiments of the present invention, various non-limiting embodiments of the present application are described in detail below.

Referring to fig. 2, fig. 2 is a schematic flow chart of a firmware upgrading method for a PCIE driver card according to an embodiment of the present invention, where the embodiment of the present invention may include the following:

s201: and the BMC refreshes the firmware to be updated into the storage space of the PCIE driving card through the control signal switch.

The firmware of the PCIE drive card is upgraded, and compared with the existing PCIE drive card, the PCIE drive card needs to be additionally provided with the signal switch, namely the firmware of the PCIE drive card with the signal switch is upgraded. Specifically, the firmware upgrading process of the entire PCIE driver card is controlled by the BMC. When the firmware of the PCIE driver card needs to be updated, the BMC refreshes the firmware to be updated into a storage space of the PCIE driver card through the control signal switch, where the storage space may be, for example, an EEPROM, that is, the firmware to be updated is refreshed into the EEPROM, and the EEPROM stores the latest firmware file.

S202: when a firmware updating task is detected, a driving chip of the PCIE driving card reads the firmware to be updated from the storage space through the control signal switch.

If a new firmware file appears in the memory space, such as an EEPROM, it indicates that a firmware update task can be executed, and when the firmware update task is executed, a trigger condition for the firmware update task may be preset, for example, whenever it is detected that the firmware file in the memory space is updated, the firmware update task is triggered to be executed. Or when a firmware updating instruction issued by the user through the BMC is received, the firmware updating task is triggered to be executed. The BMC reads the latest firmware of the storage space through the drive chip of the PCIE drive card and the control signal switch, and through the step, the drive chip obtains the current latest firmware and carries out firmware upgrading through a special tool. Since the firmware is updated, it is necessary to ensure that the PCIE link uses new configuration parameters in order to ensure that the PCIE link is available. Therefore, the drive chip can also configure the PCIE link parameters according to the acquired firmware to be updated.

S203: when detecting that the firmware to be updated is loaded completely, the BMC sends a link retraining instruction to the central processing unit by using the driving chip so as to retrain the PCIE link based on the PCIE link parameter and complete the firmware upgrading operation of the PCIE driving card.

After the drive chip reads the firmware to be updated from the storage space, the drive chip is loaded as a new configuration file, the training of the PCIE link is required, the BMC may configure the PCIE unit register of the drive chip to notify the CPU unit that the link needs to be trained again, the PCIE link may enter a "Recovery" state, and the link is retrained again, so that the trained PCIE link uses new configuration parameters.

In the technical scheme provided by the embodiment of the invention, the BMC refreshes the firmware to be updated into the storage space of the PCIE drive card, and reads the firmware to be updated and trains the PCIE link by operating the drive chip register by using the BMC, so that the firmware upgrading operation of the PCIE drive card is optimized without field operation or server restarting operation, the firmware upgrading efficiency is effectively improved, and the operability of firmware upgrading is improved. The firmware of the driving chip of the PCIE driving card can be upgraded remotely, a machine does not need to be off-shelf in the upgrading process, a service end does not need to be off-shelf in the upgrading process, the machine does not need to be restarted, almost no influence is caused on the service end, the maintenance cost is low, and the use experience of a user is promoted. The machine environment that same material number integrated circuit board can the adaptation can be more, can be unified by BMC upgrade firmware after the integrated circuit board is electrified, then put on the shelf and the operation business, need not again according to the parameter difference and go to modify integrated circuit board PN and manage and control to can accomplish the firmware upgrade operation of machine in batches in the short time.

It should be noted that, in the present application, there is no strict sequential execution order among the steps, and as long as the logical order is met, the steps may be executed simultaneously or according to a certain preset order, and fig. 2 is only an exemplary manner, and does not represent that only the execution order is the order.

In the foregoing embodiment, how to execute step S202 is not limited, and an optional implementation manner of reading the firmware to be updated from the storage space through the control signal switch for the driver chip using the PCIE driver card in this embodiment may include the following steps:

judging whether the storage space has write operation or not;

if the storage space does not execute the write operation, a drive chip of the PCIE drive card reads the firmware to be updated from the storage space through a control signal switch;

if the storage space is executing the write operation, starting a state monitoring process for monitoring the write operation of the storage space; when the write operation is detected to be finished, namely the status monitoring process feeds back the end of the write operation, the drive chip of the PCIE drive card reads the firmware to be updated from the storage space through the control signal switch.

In this embodiment, in order to ensure the accuracy of firmware upgrade and ensure that the currently upgraded firmware version is the latest firmware version in the storage space, only one of the driver chip and the BMC of the PCIE driver card can perform read/write operation on the storage space at the same time, that is, when the BMC refreshes the firmware to be updated in the storage space, the driver chip cannot read data from the storage space.

It can be understood that, the PCIE driver card is installed in the server to implement expansion of PCIE resources by the server, and accordingly, after the driver chip sends the link retraining instruction to the central processing unit, the method may further include:

The central processing unit CPU in this embodiment is a node of the server, the PCIE link includes an uplink PCIE link between the CPU and the driver chip and a downlink PCIE link between the driver chip and the PCIE interface, after the PCIE link is trained, the PCIE link can be used normally, and the CPU can implement peripheral connection connected to the PCIE interface through the PCIE link. Furthermore, the target node can be connected to a PCIE interface of the PCIE driver card through a cable, so as to implement decoupling and interconnection of PCIE resources and the server node based on the retrained PCIE link; the target node is a GPU node and/or an NVME node and/or a network node.
