[0002] A PCIe switch is a crucial piece of computer hardware, primarily used for managing, allocating, and transmitting data on the PCI-Express (Peripheral Component Interconnect Express, a high-speed serial computer expansion bus standard). To ensure the proper functioning of a PCIe switch, its software needs frequent upgrades. However, traditional PCIe switch upgrades are achieved by calling the vendor's library via IIC (Inter-Integrated Circuit). This method requires manual intervention and is time-consuming, consuming significant manpower, resources, and time, and is prone to operational errors.

[0003] Therefore, how to solve the problems of complex PCIe Switch upgrade process and long upgrade time is a problem that still needs to be solved in this field. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a PCIe switch upgrade method, apparatus, device, and storage medium, which can realize automatic upgrades of PCIe switches, simplify the upgrade process, reduce manual intervention, and improve upgrade efficiency and accuracy.

[0007] The PCIe switch upgrade module sends the upgrade preparation command generated by the target universal asynchronous transceiver (UART) path to the PCIe switch to be upgraded located on the motherboard, and sends the upgrade preparation response to the PCIe switch upgrade module through the PCIe switch to be upgraded.

[0008] When the PCIe switch to be upgraded receives an upgrade command containing the firmware to be upgraded sent by the PCIe switch upgrade module after receiving the upgrade preparation response, it uses the firmware to upgrade itself to perform an upgrade operation.

[0009] Optionally, before sending the preparation upgrade command generated by the PCIe switch upgrade module to the PCIe switch to be upgraded located on the motherboard via the target universal asynchronous transceiver path, the method further includes:

[0010] The handshake request generated by the PCIe switch upgrade module is sent to the PCIe switch to be upgraded located on the motherboard through the target universal asynchronous transceiver (UART) path, and after the handshake is successful, the PCIe switch to be upgraded sends a handshake success response to the PCIe switch upgrade module through the PCIe switch to be upgraded.

[0011] Optionally, switching the Universal Asynchronous Receiver / Transmitter (UART) path of the debug module currently located on the motherboard to the target UART path connected to the pre-created PCIe switch upgrade module includes:

[0012] The complex programmable logic device in the motherboard switches the UDP path of the debug module currently located on the motherboard to the target UDP path connected to the pre-created PCIe switch upgrade module.

[0013] Optionally, the PCIe switch upgrade module is connected to the complex programmable logic device in the motherboard via the target in-situ signal and the universal asynchronous transceiver bus.

[0014] Optionally, after upgrading itself using the firmware to be upgraded, the process further includes:

[0015] Determine whether the upgrade was successful. If the upgrade was successful, send a corresponding upgrade success signal to the PCIe switch upgrade module. If the upgrade failed, send a corresponding upgrade failure signal to the PCIe switch upgrade module.

[0016] Optionally, after upgrading itself using the firmware to be upgraded, the process further includes:

[0017] When the complex programmable logic device detects that the target presence signal is not present, it performs a restart operation to make the firmware to be upgraded effective.

[0018] Optionally, when the PCIe switch to be upgraded receives an upgrade command containing the firmware to be upgraded sent by the PCIe switch upgrade module after receiving the upgrade preparation response, the upgrade operation using the firmware to be upgraded includes:

[0019] When the PCIe switch to be upgraded receives an upgrade command containing the firmware to be upgraded from the PCIe switch upgrade module after receiving the upgrade preparation response within a first preset time, it uses the firmware to upgrade itself to perform an upgrade operation.

[0020] Secondly, this application discloses a PCIe switch upgrade device, comprising:

[0021] The path switching module is used to switch the Universal Asynchronous Receiver / Transmitter (UART) path of the debug module currently located on the motherboard to the target UART path connected to the pre-created PCIe switch upgrade module when the target presence signal is detected.

[0022] The instruction sending module is used to send the preparation upgrade instruction generated by the PCIe switch upgrade module to the PCIe switch to be upgraded located on the motherboard through the target universal asynchronous transceiver path.

[0023] The response sending module is used to send a preparation upgrade response to the PCIe switch upgrade module through the PCIe switch to be upgraded.

[0024] The PCIe switch upgrade module is used to upgrade itself using the firmware to be upgraded when the PCIe switch to be upgraded receives an upgrade command containing the firmware to be upgraded sent by the PCIe switch upgrade module after receiving the upgrade preparation response.

[0025] Thirdly, this application discloses an electronic device, including a processor and a memory; wherein, when the processor executes a computer program stored in the memory, it implements the aforementioned PCIe switch upgrade method.

[0026] Fourthly, this application discloses a computer-readable storage medium for storing a computer program; wherein, when the computer program is executed by a processor, it implements the aforementioned PCIe switch upgrade method.

[0027] As can be seen, when the target presence signal is detected, this application first switches the Universal Asynchronous Receiver / Transmitter (UART) path of the debug module currently located on the motherboard to the target UART path connected to the pre-created PCIe switch upgrade module. Then, through the target UART path, the upgrade preparation command generated by the PCIe switch upgrade module is sent to the PCIe switch to be upgraded located on the motherboard. The PCIe switch to be upgraded then sends an upgrade preparation response to the PCIe switch upgrade module. When the PCIe switch to be upgraded receives the upgrade command containing the firmware to be upgraded sent by the PCIe switch upgrade module after receiving the upgrade preparation response, it uses the firmware to upgrade itself. This application, through a pre-created PCIe switch upgrade module with high-speed transmission, low latency, and scalability, can achieve automatic PCIe switch upgrades without relying on the BMC or opening the chassis, simplifying the upgrade process, reducing manual intervention, and improving upgrade efficiency and accuracy, while greatly meeting the upgrade needs of PCIe switches.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] This application discloses a PCIe switch upgrade method. See also Figure 1 As shown, the method includes:

[0036] Step S11: When the target presence signal is detected, switch the Universal Asynchronous Receiver / Transmitter (UART) path of the debug module currently located on the motherboard to the target UART path connected to the pre-created PCIe switch upgrade module.

[0037] In this embodiment, a pre-created PCIe switch automatic upgrade device is established. This device specifically includes a PCIe switch upgrade module and a connecting cable. The PCIe switch upgrade module may include a memory, a microcontroller, and a Universal Asynchronous Receiver / Transmitter (UART) interface. The connecting cable may be a UART bus. The memory can be used to store the firmware (FW) of the PCIe switch to be upgraded. See also... Figure 2 As shown, the PCIe switch upgrade module in this device can be connected to the Complex Programmable Logic Device (CPLD) on the motherboard containing the PCIe switch to be upgraded via a set of in-situ signals (i.e., Present signals) and a Universal Asynchronous Receiver / Transmitter Bus (i.e., UART bus), which features high-speed transmission, low latency, and portability. Specifically, the motherboard may include, but is not limited to, the CPLD, the PCIe switch, the BMC (Baseboard Management Controller), the BIOS (Basic Input Output System), and the NIC (Network Interface Card).

[0038] In this embodiment, when the complex programmable logic device in the motherboard detects the presence of the target presence signal, i.e., when the PCIe switch upgrade module is inserted, it first switches the Universal Asynchronous Receiver / Transmitter (UART) path of the debug module currently located in the motherboard to the target UART path connected to the PCIe switch upgrade module. Figure 2 Switch from UART1 to UART2 so that the PCIe switch can be upgraded via UART2 in the future.

[0039] Specifically, switching the UART path of the debug module currently located on the motherboard to the target UART path connected to the pre-created PCIe switch upgrade module can include: switching the UART path of the debug module currently located on the motherboard to the target UART path connected to the pre-created PCIe switch upgrade module via a complex programmable logic device (CPLD) on the motherboard. That is, the UART path of the PCIe switch upgrade module can be switched between other debug modules via a CPLD.

[0040] Step S12: Send the upgrade preparation command generated by the PCIe switch upgrade module to the PCIe switch to be upgraded located on the motherboard through the target universal asynchronous transceiver (UART) path, and send the upgrade preparation response to the PCIe switch upgrade module through the PCIe switch to be upgraded.

[0041] In this embodiment, after switching the Universal Asynchronous Receiver / Transmitter (UART) path of the debugging module currently located on the motherboard to the target UART path connected to the PCIe switch upgrade module, the PCIe switch upgrade module generates a corresponding upgrade preparation command and sends the upgrade preparation command to the PCIe switch to be upgraded located on the motherboard through the target UART path. When the PCIe switch to be upgraded receives the upgrade preparation command sent by the PCIe switch upgrade module, it further sends an upgrade preparation response to the PCIe switch upgrade module.

[0042] It should be noted that before sending the upgrade preparation command generated by the PCIe switch upgrade module to the PCIe switch to be upgraded located on the motherboard via the target Asynchronous Receiver / Transmitter (UART) path, the process further includes: sending the handshake request generated by the PCIe switch upgrade module to the PCIe switch to be upgraded located on the motherboard via the target UART path, and after a successful handshake, sending a handshake success response from the PCIe switch to the PCIe switch upgrade module via the PCIe switch to be upgraded. That is, before sending information, a handshake connection is established between the PCIe switch upgrade module and the PCIe switch to be upgraded. Specifically, the handshake request generated by the PCIe switch upgrade module is first sent to the PCIe switch to be upgraded located on the motherboard via the target UART path, and then, after a successful handshake, a handshake success response is sent from the PCIe switch to the PCIe switch upgrade module via the PCIe switch to be upgraded.

[0043] Step S13: When the PCIe switch to be upgraded receives the upgrade command containing the firmware to be upgraded sent by the PCIe switch upgrade module after receiving the upgrade preparation response, it uses the firmware to upgrade itself to perform the upgrade operation.

[0044] In this embodiment, after the PCIe switch upgrade module receives the above-mentioned upgrade preparation response, it will send an upgrade command to the PCIe switch to be upgraded. The upgrade command contains the firmware to be upgraded. Furthermore, after the PCIe switch to be upgraded receives the upgrade command sent by the PCIe switch upgrade module, it can use the firmware to be upgraded in the upgrade command to perform an upgrade operation on itself.

[0045] Furthermore, after performing the upgrade operation using the firmware to be upgraded, the process may further include: determining whether the upgrade was successful; if successful, sending a corresponding upgrade success signal to the PCIe switch upgrade module; if unsuccessful, sending a corresponding upgrade failure signal to the PCIe switch upgrade module. In this embodiment, after performing the upgrade operation on the PCIe switch using the firmware to be upgraded, it is possible to further determine whether the PCIe switch upgrade was successful. If the PCIe switch upgrade was successful, a corresponding upgrade success signal is sent to the PCIe switch upgrade module, at which point the PCIe switch automatic upgrade device can be disconnected; if the PCIe switch upgrade failed, a corresponding upgrade failure signal is sent to the PCIe switch upgrade module.

[0046] Additionally, after upgrading itself using the firmware to be upgraded, the process may further include: when the complex programmable logic device detects that the target presence signal is not present, performing a restart operation to make the firmware to be upgraded effective. In this embodiment, when the PCIe switch upgrade is successful and the PCIe switch automatic upgrade device is unplugged, the complex programmable logic device in the motherboard can detect that the target presence signal is not present. At this time, a restart operation can be performed on the current host, such as a server, to make the firmware to be upgraded effective.

[0047] As can be seen from the above, the PCIe switch upgrade module and the motherboard in this embodiment are connected via a UART bus. Compared to the traditional method of connecting the BMC to the PCIe switch via IIC and then upgrading by calling the lib library, the UART bus, with its advantages of high-speed transmission, low latency, and portability, is more suitable for automatic PCIe switch upgrades. It can shorten the upgrade time to a few minutes, far less than the hourly upgrade speed of traditional methods. On the other hand, the automatic PCIe switch upgrade device created in this application is highly portable and suitable for various data center environments. It can quickly upgrade PCIe switches without relying on the BMC or opening the chassis.

[0048] As can be seen, in this embodiment, when the target presence signal is detected, the Universal Asynchronous Receiver / Transmitter (UART) path of the debug module currently located on the motherboard is first switched to the target UART path connected to the pre-created PCIe switch upgrade module. Then, the upgrade preparation command generated by the PCIe switch upgrade module is sent to the PCIe switch to be upgraded located on the motherboard through the target UART path. The PCIe switch to be upgraded sends an upgrade preparation response to the PCIe switch upgrade module. When the PCIe switch to be upgraded receives the upgrade command containing the firmware to be upgraded sent by the PCIe switch upgrade module after receiving the upgrade preparation response, it uses the firmware to upgrade itself. This embodiment, through a pre-created PCIe switch upgrade module with high-speed transmission, low latency, and scalability, can achieve automatic PCIe switch upgrades without relying on the BMC or opening the chassis, simplifying the upgrade process, reducing manual intervention, and improving upgrade efficiency and accuracy, while greatly meeting the upgrade needs of PCIe switches.

[0049] This application discloses a specific PCIe switch upgrade method. (See also...) Figure 2 As shown, the method includes:

[0050] Step S21: When the target presence signal is detected, the general asynchronous transceiver path of the debug module currently located on the motherboard is switched to the target general asynchronous transceiver path connected to the pre-created PCIe switch upgrade module through the complex programmable logic device in the motherboard.

[0051] Step S22: Send the handshake request generated by the PCIe switch upgrade module to the PCIe switch to be upgraded located on the motherboard through the target universal asynchronous transceiver (UART) path, and after the handshake is successful, send a handshake success response to the PCIe switch upgrade module through the PCIe switch to be upgraded.

[0052] In this embodiment, after switching the Universal Asynchronous Receiver / Transmitter (UART) path of the debugging module currently located on the motherboard to the target UART path connected to the pre-created PCIe switch upgrade module, the PCIe switch upgrade module generates a corresponding handshake request and sends the handshake request to the PCIe switch to be upgraded on the motherboard through the aforementioned target UART path. Furthermore, the PCIe switch upgrade module will continue to determine whether it can obtain a response from the PCIe switch to be upgraded within a preset time. If it does, it indicates that the handshake between the two is successful; otherwise, it indicates that the handshake between the two has failed.

[0053] Step S23: Send the upgrade preparation command generated by the PCIe switch upgrade module to the PCIe switch to be upgraded located on the motherboard through the target universal asynchronous transceiver (UART) path, and send the upgrade preparation response to the PCIe switch upgrade module through the PCIe switch to be upgraded.

[0054] In this embodiment, after the PCIe switch upgrade module and the PCIe switch to be upgraded successfully handshake, the PCIe switch upgrade module can further generate a preparation upgrade command and send it to the PCIe switch to be upgraded in the motherboard. It can then determine whether a response can be obtained from the PCIe switch to be upgraded within a preset time. If a response is obtained, it indicates that the preparation upgrade command was successfully sent; otherwise, it indicates that the preparation upgrade command failed to be sent.

[0055] Step S24: When the PCIe switch to be upgraded receives an upgrade command containing the firmware to be upgraded from the PCIe switch upgrade module after receiving the upgrade preparation response within a first preset time within a second preset time within a second preset time, it uses the firmware to be upgraded to perform an upgrade operation on itself.

[0056] In this embodiment, when the PCIe switch to be upgraded receives the upgrade command sent by the PCIe switch upgrade module within a first preset time, such as 1 minute, and within a second preset time, such as 3 seconds, after receiving the upgrade preparation response, the upgrade operation is further performed using the firmware to be upgraded in the upgrade command.

[0057] Step S25: When the complex programmable logic device detects that the target presence signal is not present, a restart operation is performed to make the firmware to be upgraded effective.

[0058] For more detailed processing procedures of steps S21 and S25, please refer to the corresponding content disclosed in the foregoing embodiments, which will not be repeated here.

[0059] As can be seen, the embodiments of this application, through the pre-created PCIe switch upgrade module with features such as high-speed transmission, low latency, and scalability, can quickly upgrade PCIe switches without relying on the BMC or opening the chassis, shortening the upgrade time. Furthermore, it is applicable to various data center environments where customers are located, reduces manual intervention, and can greatly meet the upgrade needs of various devices containing PCIe switches.

[0060] For example, when upgrading a PCIe switch, a pre-created PCIe switch upgrade module can be manually connected to the motherboard containing the PCIe switch to be upgraded. At this point, the CPLD in the motherboard can detect an presence signal, indicating that the PCIe switch upgrade module has been connected, and switches the current UART path to the PCIe switch upgrade module's UART path. Then, the PCIe switch upgrade module sends a handshake request to the PCIe switch and checks for a response within a preset time (e.g., 3 seconds). If a response is received, it continues to send an upgrade preparation command to the PCIe switch. The system then checks for a response within a preset time (e.g., 3 seconds). If a response is received, it sends the firmware to be upgraded to the PCIe switch. If a response is received within a preset time (e.g., 1 minute), it sends an upgrade command to the PCIe switch. The PCIe switch then performs the upgrade using the firmware. Once the PCIe switch upgrade module receives a successful PCIe upgrade signal within a preset time (e.g., 3 minutes), the PCIe switch upgrade module can be removed. The host will detect that the presence signal (i.e., the Present signal) is not present. At this point, the server can be restarted to make the newly input firmware take effect.

[0061] Accordingly, this application also discloses a PCIe switch upgrade device, see [link to relevant documentation]. Figure 4 As shown, the device includes:

[0064] The response sending module 13 is used to send a preparation for upgrade response to the PCIe switch upgrade module through the PCIe switch to be upgraded.

The PCIe switch to be upgraded sends an upgrade preparation response to the PCIe switch upgrade module.
