The specific operation is as follows:

As shown in Figure 2, the schematic diagram of the X86 server system structure when the IO device firmware is upgraded, the new firmware version is sent to the operating system (Operation System, OS) of the X86 system host through an external management device or manually, and the OS calls the upgrade tool through the driver Write the new firmware version into the memory of the IO device to replace the existing firmware version in the memory of the IO device, so as to realize the firmware upgrade of the IO device.

The upgrade solution of the above-mentioned IO device firmware mainly depends on the OS, upgrade tools and drivers of the X86 system host. In the existing IO device firmware upgrade solution, if the IO device firmware upgrade is performed manually, because different people install different OSs, different OS installations have different upgrade tools and drivers, resulting in inconsistent IO device firmware upgrade operations manually. ; If the remote management software operates the IO device firmware upgrade, the OS needs to be equipped with an engine (Agent) and an upgrade tool, which makes the operation of the IO device firmware upgrade solution complicated.

To sum up, the solution of upgrading the firmware of IO devices relying on OS, upgrade tools and drivers has the problem of inconsistency in manual IO device firmware upgrade operations due to different OSs, or due to remote management software operating IO device firmware. The upgrade makes the operation of the IO device firmware upgrade solution complicated and the realizability is low.

There are four ways to realize the direct connection between the firmware upgrade system and the IO device:

Method 1: The firmware upgrade system is installed on the baseboard management controller BMC, and the connection between the firmware upgrade system and the IO device is based on MCTP.

Taking the X86 service system as an example, when the firmware upgrade system is installed on the baseboard management controller (BMC) of the X86 service system, the structural diagram of the X86 service system is shown in Figure 6. The connection between the firmware upgrade system and the IO device supports bus carrying MCTP protocol (Management Component Transport Protocol, MCTP over PCIe), between the firmware upgrade system and the IO device, the bus carries the PCIe communication channel for direct file transfer.

Among them, the connection between the firmware upgrade system and the IO device in method 1 and method 2 is based on MCTP, and the file transfer between the firmware upgrade system and the IO device needs to pass through the PCIe communication channel, which is an inherent connection between the firmware upgrade system and the IO device. ; In methods 3 and 4, before the file transfer between the firmware upgrade system and the IO device, a communication channel between the firmware upgrade system and the IO device needs to be established. This communication channel is not a PCIe communication channel, and can be a two-wire type Serial bus (I2C, Inter-Integrated Circuit) or Ethernet and other network ports, and then the firmware upgrade system and IO devices can directly transfer files through the established communication channel.

For the connection mode between the firmware upgrade system and the IO device in the above mode 1 or the connection mode between the firmware upgrade system and the IO device in the mode 2, the upgrade file transmission method of the IO device firmware in the embodiment of the present invention is as follows:

The firmware upgrade system divides the IO device firmware upgrade file into multiple IO device firmware upgrade messages conforming to the MCTP message format based on the length of the MCTP message supported by the IO device. The sequence in the device firmware upgrade file determines the sequence number carried in each IO device firmware upgrade message.

When the firmware upgrade system determines that the IO device firmware upgrade message with sequence number 1 is successfully received by the IO device, the firmware upgrade system transmits the IO device firmware upgrade message with sequence number 5 to the IO device. Specifically, the firmware upgrade system can slide the window shown in Figure 8b backwards to transmit the firmware upgrade message of the IO device with the sequence number 5 to the IO device; or, the firmware upgrade system can use the IO device with the sequence number 1. The window corresponding to the device firmware upgrade message (as shown in FIG. 8a ) transmits the IO device firmware upgrade message with sequence number 5 to the IO device. When the firmware upgrade system cannot determine that the IO device firmware upgrade message with sequence number 1 is successfully received by the IO device, the firmware upgrade system uses the original window to retransmit the IO device firmware upgrade message with sequence number 1 to the IO device.

In the embodiment of the present invention, there are many ways for the firmware upgrade system to send the IO device firmware upgrade message carrying the sequence number to the IO device. For example, the IO device firmware upgrade message can be sent to the IO device in the order of the sequence number. IO device firmware upgrade messages can be sent to the IO device in random order.

For the connection mode between the firmware upgrade system and the IO device in the third mode above or the connection mode between the firmware upgrade system and the IO device in the mode four, the upgrade file transmission method of the IO device firmware in the embodiment of the present invention is as follows:

The firmware upgrade system receives the firmware upgrade information sent by the IO device according to the firmware upgrade request control message. The firmware upgrade information includes the firmware upgrade supported by the IO device and the length of the message supported by the IO device.

Preferably, the firmware upgrade system in S502 splits the IO device firmware upgrade file according to the message length supported by the IO device, and obtains a plurality of IO device firmware upgrade messages carrying sequence numbers, including:

The firmware upgrade system divides the IO device firmware upgrade file into multiple IO device firmware upgrade messages based on the length of the message supported by the IO device, and according to the sequence of each IO device firmware upgrade message in the IO device firmware upgrade file Sequence, to determine the sequence number carried in each IO device firmware upgrade message.

Preferably, the method for the firmware upgrade system in S503 to transmit the IO device firmware upgrade message carrying the sequence number to the IO device includes:

The firmware upgrade system continuously transmits a specified number of IO device firmware upgrade messages to the IO device according to the sequence number, and the number of continuously transmitted IO device firmware upgrade messages is the same as the number of windows used to transmit the IO device firmware upgrade messages;

When it is determined that the current IO device firmware upgrade message transmitted is successfully received by the IO device, the firmware upgrade system transmits the next IO device firmware upgrade message to the IO device according to the sequence number; or when the currently transmitted IO device firmware upgrade message is not determined within the specified time When the IO device firmware upgrade message is successfully received by the IO device, the firmware upgrade system retransmits the IO device firmware upgrade message to the IO device.
