Description

Method and system for actively reporting log information by BMC
Technical Field
The invention belongs to the technical field of GPU resource allocation, and particularly relates to a high-efficiency GPU resource allocation optimization method and system.
Background
In the development and use processes of the server, a Central Processing Unit (CPU), a memory, a hard disk, a power supply, temperature, voltage, a fan, power consumption, and the like need to be monitored. Bmc (Baseboard Management Controller) is a key component for detecting and controlling a server. The server diagnostic system needs to obtain error information by reading Bmc detection log. How the server system can timely acquire and process the error report of Bmc is very necessary. Currently, bmc supports passive reading of in-band commands or active reporting of out-of-band snmp. 5363 a passive reading mode of an in-band command of Bmc needs an app or a diagnostic system to repeatedly access a Bmc system at regular time, but the real-time performance is not strong enough, and the execution efficiency is relatively low; polling access all the time also occupies more resources. Out-of-band snmp (Simple Network Management Protocol) access is not applicable to the case of the native system.
Fig. 1 shows a flowchart of a method for BMC to passively search for logs in the prior art. One piece of log information of the BMC goes through roughly two main processes, taking a log file generated by the sensor 1 as an example. A certain memory space is divided in the BMC system, and a BMC log file is stored. The BMC collects the log information of the sensors 1 and stores them in the system's BMC log file.
The diagnostic system accesses the BMC system through a command to inquire whether the log file of the sensor 1 exists or not, the CPU searches whether the log file of the sensor 1 exists or not in the BMC log file, if yes, a related log is returned, and if not, a value of 0 is returned. The BMC passive lookup method has the following advantages and disadvantages. Has the advantages that: the BMC system and the diagnosis system communicate through an Ipomitool tool, and the Ipomitool is widely used and has strong stability; the diagnosis system is used as an active party, and the functions do not relate to pointers and the like, so that the realization is relatively simple. The disadvantages are: a certain memory space is divided in the BMC system, and a log file generated by the BMC in the process of storing the BMC log file is stored in the BMC log file and cannot be transmitted in time, so that the instantaneity of information transmission is not strong enough. Critical log information, if any, may delay the diagnosis of the diagnostic system. And the memory space of the BMC system is relatively small, and the BMC log file occupies a certain memory space. The diagnostic system accesses the BMC system through a command, and the process of inquiring whether the log file of the sensor 1 exists is as follows: the diagnostic system does not know whether a corresponding sensor log is generated in the BMC system, but only accesses the BMC system at regular times or at the end of each test item of the diagnostic system. This results in polling access occupying more resources and not necessarily getting the data that one wants; on the other hand, if the access is performed at the end of each test item, but some stress tests have a test time as long as several hours, if the corresponding error log is generated at the beginning of the BMC, the results can only be checked after several hours, and the real-time performance is not strong enough.

Detailed Description
In order to clearly explain the technical features of the present invention, the present invention will be explained in detail by the following embodiments and the accompanying drawings. The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and procedures are omitted so as to not unnecessarily limit the invention.
Example 1
The embodiment 1 of the invention provides a method for actively reporting log information by a BMC, wherein a BMC unit collects the log information of each sensor, sends a hand-lifting request to a CPU of the BMC unit, and transmits the log information to a predefined log registry after the CPU allows the hand-lifting request; enabling the diagnosis unit to send the address parameter of the callback function through the log registry, and returning the address of the log registry as the input of the callback function to the diagnosis unit; and receiving the address report log information of the callback function returned by the diagnosis unit, and enabling the diagnosis unit to perform corresponding processing according to the log information.
Fig. 2 is a schematic diagram illustrating an implementation of a method for BMC to actively report log information according to embodiment 1 of the present invention.
In the invention, a unique identifier is set between the BMC unit and the diagnosis unit, the communication of the processes between the systems is realized through RPC (Remote Procedure Call Protocol) communication, and the port numbers of the IP of the BMC unit and the IP of the diagnosis unit, namely the process numbers, are required to be used as the unique identifier for identity identification.
And the RPC virtual platform is provided with corresponding interfaces in the BMC unit and the diagnosis unit. For the diagnostic unit, the BMC unit is the standard interface, no matter how the BMC unit itself passes the value of the interface or what language is used to implement the interface. And vice versa. A BMC log information registry corresponding to each other is arranged between the two units, and log information can be transmitted across the units through the registry.
The BMC chip collects the log information of each sensor, firstly sends a hand-lifting request to a CPU of the BMC unit through interruption, and sends the BMC log information to the CPU after permission is obtained. After receiving the log information, the CPU determines whether the log is reported to the diagnosis unit according to the key log registry. According to the invention, the BMC unit does not need to store the log information into the log file, but reports the log information to the CPU in time through interruption, so that the timeliness is improved, and the consumption of the memory is reduced.
The diagnosis unit realizes a callback function, takes the address of the BMC log registry as a parameter, and correspondingly processes different parameters. For example, return to the previous test, interrupt the test, retest the current item, etc., and generate the corresponding prompt message. The callback function of the diagnostic unit is not used in the diagnostic unit, but the BMC unit places the BMC log information registry in the corresponding address. When the BMC unit generates corresponding log information and puts the address of the callback function, the callback mechanism is triggered. And the diagnosis unit receives and processes the address value returned by the callback function.
The diagnostic unit produces an individual thread and waits for the BMC to trigger the BMC log information in the registry.
The diagnostic unit initiates a thread, the address of the BMC log registry is transmitted as a parameter, the log is waited to be uploaded, once the BMC log reported by the BMC unit is received, the callback mechanism is triggered, the thread starts to execute, and the diagnostic unit generates corresponding processing measures in time. Because polling access is mostly useless, the diagnosis unit does not poll and access the BMC unit any more, but initiates a thread to wait for the report of the BMC unit, and the bandwidth and the server resource occupied during polling access are saved.
