In order to be convenient for a user to freely select customized configuration in the edge server, a detachable modularized BMC configuration scheme of 'RunBMC' is adopted. In this case, the server operation needs to adaptively support both operation policies of the presence or absence of the BMC. For the general server system, the BMC controls the read-write function of FRU information of the whole machine and the board card, and the BIOS interacts with the BMC to acquire the FRU information in the starting process of the system, so that the read-write of the FRU information to the EEPROM is not involved. To implement the function of reading and writing the FRU information when the BMC is not in time, the task of communicating with the EEPROM needs to be performed by the BIOS, and the BMC needs to wait for the BIOS to send the FRU information in the starting process, so that the BMC is not involved in the modification of the FRU. However, the BIOS can only run in the starting process, and performs the read-write operation of the FRU, so that the remote and batch quick implementation superiority of the BMC is lost.

For the general server system, the BMC controls the read-write function of FRU information of the whole machine and the board card, and the BIOS interacts with the BMC to acquire the FRU information in the starting process of the system, so that the read-write of the FRU information to the EEPROM is not involved. To implement the function of reading and writing the FRU information when the BMC is not in time, the task of communicating with the EEPROM needs to be performed by the BIOS, and the BMC needs to wait for the BIOS to send the FRU information in the starting process, so that the BMC is not involved in the modification of the FRU. However, the BIOS can only run in the starting process, and performs the read-write operation of the FRU, so that the remote and batch quick implementation superiority of the BMC is lost.

The invention provides a self-adaptive control right distribution method of FRU information memory, firstly, connecting the I2C channels of BMC and BIOS to a double-host selection chip, and connecting the BMC and BIOS to the FRU information memory through the double-host selection chip; the BMC and BIOS are set to FRU information storage formats consistent with memory. When the BMC is in place, the BMC and the BIOS dynamically allocate the control right of the double-host selection chip according to the on-off state of the system, and perform read-write operation of FRU information on the FRU information memory; when the BMC is out of place, the BIOS grasps the control right of the double-host selection chip, and executes the read-write operation of FRU information on the FRU information memory in the system starting stage. Therefore, the invention realizes the read-write operation of the FRU information memory by the BIOS and the BMC together, dynamically distributes the control right of the FRU information memory by the double-host selection chip, realizes the self-adaptive distribution of channels under different conditions, and simultaneously reserves the read-write function of the BMC and the BIOS to the FRU information memory.

In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Embodiment one:

as shown in fig. 1, the embodiment provides an adaptive control right allocation method for a FRU information memory, which includes the following steps:

s1: the I2C channels of the BMC and the BIOS are connected to the dual host selection chip, and are connected to the FRU information memory through the dual host selection chip. Wherein the FRU information memory is used only for storing FRU information.

S2: the BMC and BIOS are set to FRU information storage formats consistent with memory.

S3: when the BMC is in place, the BMC and the BIOS dynamically allocate the control right of the double-host selection chip according to the on-off state of the system, and perform read-write operation of FRU information on the FRU information memory.

In the step, the automatic switching of the control right of the double-host selection chip is performed according to the on-off state. Specifically:

In addition, if the system receives the FRU information writing command of the BIOS at the start-up, the BIOS acquires the control right of the dual-host selection chip, performs the FRU information writing operation on the FRU information storage, and discards the control right after the operation is completed.

S4: when the BMC is out of place, the BIOS grasps the control right of the double-host selection chip, and executes the read-write operation of FRU information on the FRU information memory in the system starting stage.

It should be noted that, in this embodiment, the dual-host selection chip uses a PCA9641 chip, and the FRU information memory uses an EEPROM chip.

The embodiment provides a self-adaptive control right distribution method of FRU information storage, which dynamically realizes flexible control of BMC and BIOS on FRU information by self-adaptively distributing control right of double-host selection chips, and the two can simultaneously have the function of writing FRU information, thereby not only meeting the functions of remotely and rapidly setting a large number of board card FRU information in batches of BMC in a general state, but also supporting the FRU information read-write of a remote in-band system through BIOS. The problem that BIOS FRU can not be realized through BMC interaction under the condition of optionally matching RunBMC in the edge server is solved.

Embodiment two:

based on the first embodiment, the present embodiment also discloses a method for allocating adaptive control rights of the FRU information memory, which specifically includes the following steps:

1. as shown in fig. 2, the I2C channels of the BMC and BIOS are connected to two different channels of the PCA9641 chip, and through the PCA9641 chip to the EEPROM that holds the FRU information.

2. The BMC and the FRU information format stored and set by the BIOS are kept consistent, and the format is kept consistent with the FRU information set in the EEPROM. The aim is to make the FRU information set by BMC and BIOS accurately analyzed. The EEPROM for storing FRU information does not store other information any more, so that the function is not affected.

3. The following scheme is installed to set the FRU control right allocation scheme:

3.1, when RunBMC is in place:

3.1.1, under the system shutdown state, the BMC acquires the PCA9641 control right to realize the read-write function of the FRU, and is consistent with the general function;

3.1.2, after the boot operation is executed, the BMC discards the PCA9641 control right, and does not read and write the EEPROM with FRU information in the boot process. The BMC displays FRU information by acquiring information stored in a memory, and temporarily closes the FRU writing function (IPMI);

3.1.3 in the starting-up process, the BIOS and the BMC can normally communicate in an IPMI or shared memory mode, and the BIOS defaults to acquire FRU information from the BMC, but if the Selftest information of the BMC returns to Failed, the health state of the BMC is judged to be abnormal, the BIOS acquires the control right of PCA9641, the FRU information is independently read, and the control right is discarded after the FRU information is read. In addition, if the FRU writing command of the BIOS is received before the power-on, the BIOS will also acquire the PCA9641 control right, write FRU information, and discard the control right;

3.1.4, after the startup is completed, the BMC detects the POST Code interacted by the BIOS, and after the startup is completed, the PCA9641 control right is acquired again, and FRU is read and written normally.

3.2, when RunBMC is out of place:

3.2.1, the control right of PCA9641 will be grasped by BIOS, and the FRU information is read and written during the start-up stage.

The embodiment provides a self-adaptive control right distribution method of FRU information storage, which dynamically realizes flexible control of BMC and BIOS on FRU by self-adaptively distributing PCA9641 control right, and can simultaneously have the function of writing FRU, thereby not only meeting the functions of remote and batch quick setting of a large number of board FRU of BMC in a general state, but also supporting the FRU reading and writing of a remote in-band system through BIOS. The problem that BIOS FRU can not be realized through BMC interaction under the condition of optionally matching RunBMC in the edge server is solved.
