Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present 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.
Referring to fig. 1, fig. 1 is a flowchart of a device monitoring method of a BMC according to an embodiment of the present invention. The method may include:
step 101: and acquiring an overrun signal sent by the monitoring device.
The monitoring device in this step may be a device capable of monitoring, such as a temperature sensor, an analog-to-digital converter (ADC), a Voltage Regulator (VR), and the like.
Specifically, the overrun signal in this step may be a signal for prompting the monitoring data of the monitoring device to exceed the monitoring threshold, that is, a signal that is output to the BMC after the monitoring device detects that the monitored monitoring data exceeds the monitoring threshold, for example, an interrupt signal (such as a low level signal) of an alert pin (alert# pin). The embodiment does not limit the specific signal type of the overrun signal sent by the monitoring device, for example, the overrun signal may be an interrupt signal output by a preset pin (such as an alarm pin) of the monitoring device, that is, the monitoring device detects that the monitoring data exceeds the monitoring threshold value and then outputs the interrupt signal through the preset pin; that is, in this step, the BMC may obtain an overrun signal sent by the alarm pin of the monitoring device; the overrun signal is an interrupt signal output by the alarm pin after the monitoring device detects that the monitoring data exceeds the monitoring threshold value. For example, in view of the fact that the SMBus (a two-wire serial bus) protocol is initially designed and positioned as Critical parameters (critical parameter) of the monitoring system, when the monitoring device and the BMC adopt SMBus protocol communication, the SMBus protocol adds an alert# pin definition on the basis of an I2C (a serial communication protocol) protocol, and when a target event occurs in the device, the alert# pin is pulled down; correspondingly, the registers in the monitoring device may further include a threshold register for storing a monitoring threshold, such as a high limit register and/or a low limit register, so that a user may write the upper limit and the lower limit of the monitoring data, such as temperature and voltage, to be monitored into the device according to the needs of the user, and when the actual monitoring data actually exceeds the upper limit and the lower limit, the logic of the device captures such a target event, further pulls down the alert# pin, and outputs a low level signal (i.e., an overrun signal) to the BMC through the alert# pin. The overrun signal may be other types of signals besides the interrupt signal, so long as the monitoring device can detect that the monitored data exceeds the monitoring threshold value and then output the overrun signal to the BMC, and the embodiment does not limit the overrun signal.
Step 102: and reading monitoring data in the monitoring device according to the overrun signal.
It can be understood that, in this step, the BMC may read the monitoring data in the monitoring device that sends the overrun signal after receiving the overrun signal.
Specifically, for the specific mode of the BMC in this step for reading the monitoring data in the monitoring device according to the overrun signal, the BMC can be set by a designer according to the practical scene and the user requirement, for example, in this embodiment, the BMC can use the monitoring thread corresponding to the monitoring device to read the monitoring data in the monitoring device according to the overrun signal; for example, the BMC may pre-configure a monitoring thread corresponding to each monitoring device in a monitoring process of the user space, for example, each monitoring thread corresponds to one type of monitoring device, for example, the monitoring device of the temperature monitoring device and the monitoring device of the voltage monitoring device may respectively correspond to one different monitoring thread.
Correspondingly, for the monitoring thread corresponding to the monitoring device, the specific mode of reading the monitoring data in the monitoring device according to the overrun signal can be set by a designer, for example, the monitoring thread corresponding to the monitoring device can directly detect the overrun signal sent by the monitoring device, so that the monitoring data in the monitoring device can be read after the overrun signal is detected. The BMC can also use the drive corresponding to the monitoring device to detect the overrun signal sent by the monitoring device, so as to control the monitoring thread corresponding to the monitoring device through the corresponding signal (such as a wake-up signal) after the drive detects the overrun signal. That is, in this step, the BMC may send a wake-up signal to a monitoring thread corresponding to the monitoring device according to the obtained overrun signal by using a driver corresponding to the monitoring device, and wake up the dormant monitoring thread; and reading monitoring data in the monitoring devices by using the monitoring threads corresponding to the monitoring devices.
Correspondingly, in the embodiment, a drive design of interrupt+asynchronous IO may be adopted, in the drive corresponding to the monitoring device, a preset pin (such as an alarm pin) of the monitoring device is used as an external interrupt source, an interrupt processing routine is registered for the monitoring device, when real-time monitoring data exceeds a monitoring threshold value, the preset pin may be pulled down to trigger interrupt, so that the interrupt routine is called, interrupt information is recorded in the interrupt routine, and a kill_fasync () function (an application function in a drive) is called to send a SIGIO signal (a drive signal, such as a wake-up signal) to a user space monitoring process, so as to inform the event that the monitoring data exceeds a limit value; at this time, the user space is responsible for monitoring the monitoring thread of the monitoring device to be awakened by the signal, and in turn, reads the monitoring data in the data register of the monitoring device and compares the monitoring data with the monitoring threshold in the threshold register.
As shown in fig. 2, in a driver corresponding to the monitoring device (i.e., the monitoring class device), in addition to having an interrupt context for capturing an alarm pin (alert #pin) and reporting a target event to the user space through an asynchronous IO, a process context for responding to an asynchronous IO request of a monitoring sub-thread (i.e., a monitoring thread) of the user space may be set, so that the monitoring sub-thread may read real-time monitoring data through the driver, for example, by using a fasync_helper () function (a kernel function) of a kernel, to implement a fasync () function (an asynchronous notification function) in a file_operations (a data structure) function set, so as to accept the asynchronous IO request of the user space.
Step 103: determining an overrun event of the monitoring device according to the monitoring data and the monitoring threshold value of the monitoring device; wherein the overrun event comprises an ultra-high event and/or an ultra-low event.
It is understood that the monitoring threshold of the monitoring device in this step may be an upper limit value and/or a lower limit value of preset monitoring data monitored by the monitoring device, so as to determine a specific type of an overrun event, such as an overrun event higher than the upper limit value and an overrun event lower than the lower limit value, through comparison of the monitoring data and the monitoring threshold.
Specifically, the embodiment does not limit the specific content and the acquisition mode of the monitoring threshold of the monitoring device, for example, the BMC may read the monitoring threshold stored in the threshold register from the monitoring device, for example, the BMC may use a monitoring thread corresponding to the monitoring device to read the monitoring threshold of the monitoring data in the monitoring device according to the overrun signal; and determining an overrun event according to the monitoring data and the monitoring threshold value. The BMC may store the monitoring threshold of the monitoring class device by itself, e.g., the monitoring threshold of the monitoring class device may be different from the upper and/or lower values in the threshold register in the monitoring class device.
Furthermore, after this step, the BMC may further control, according to the event type of the overrun event, the controlled device corresponding to the event type to perform a corresponding adjustment action. For example, a monitoring process of a user space in the BMC can adopt a framework of a main thread (namely a monitoring main thread) +a plurality of sub threads (namely monitoring threads), the BMC can utilize the monitoring main thread to control a controlled device corresponding to an event type to perform corresponding adjustment action according to the event type of an overrun event; namely, after the monitoring thread corresponding to the monitoring device is utilized by the BMC, the monitoring main thread can be notified after the overrun event of the monitoring device is determined, so that the monitoring main thread can control the controlled device corresponding to the event type to perform corresponding adjustment action according to the event type of the overrun event.
Specifically, in this embodiment, each sub-thread (i.e., a monitoring thread) may be used to manage a class of monitoring devices, and is responsible for capturing an overrun event of the device and collecting real-time data (i.e., monitoring data), where specific operations include: packaging a read-write function for accessing real-time data and upper and lower line limit data (namely monitoring threshold values), wherein a programming node called in the function is a device node for driving to be thrown to a user space, the read-write function cannot be actively called by code main line logic, and the read-write function is only called in SIGIO signal callback functions realized by sub-threads; realizing and registering a SIGIO signal callback function, registering the callback function by a signal () function (a signal processing function), calling the callback function when the SIGIO signal is sent by a driver, calling a read-write function in the callback function, acquiring real-time data and upper line limit data, updating a struct hwmon_event structure body, and then carrying out logic comparison to judge whether a main thread needs to be awakened.
Correspondingly, the main thread (i.e. the monitoring main thread) can be responsible for uniformly managing various monitoring events, abstracts a struct hwmon_event structure body for describing specific target events, and carries out instantiation by each sub-thread, wherein the structure body contains specific target event types such as over-temperature, under-voltage and the like, and can also contain the generation times of the target events, the history data of the last three times and the like; when the monitoring main thread is awakened by a certain monitoring sub-thread, the monitoring main thread can acquire an updated hwmon_event instance of the sub-thread, take out the type of a target event and related data in the sub-thread, substitute the type of the target event and related data into a data reliability algorithm, judge the severity of the event, and make corresponding follow-up actions, for example, when the event type of an overrun event is an overrun event, the BMC can utilize the main thread to adjust the rotating speed of a fan corresponding to the overrun event (namely, the rotating speed of a fan corresponding to a detection device for detecting the overrun event) to be a preset overrun rotating speed, and lighten an alarm indicator corresponding to the overrun event; and may also log the over-temperature event into a system log.
Specifically, as shown in fig. 2, after each monitoring thread (i.e., sub-thread) is created in this embodiment, an fcntl () function (a function in a computer) may be called to initiate an asynchronous IO request, and the function may finally call to a fasync () function implemented by a driver to complete asynchronous IO setting; after the asynchronous IO request is initiated, the whole user space monitoring process is initialized to be in a ready state.
When no monitoring device generates an event exceeding the limit value, the monitoring thread can be always in a dormant state (the monitoring main thread is dormant on a designated condition variable after initializing related software resources and creating each monitoring thread), at the moment, the processing resources of the BMC can be scheduled for other business processes to use, the scheduling pressure of the BMC is reduced, and the response speed of the system process is improved; when the monitoring device generates an event exceeding the limit value, the hardware logic of the monitoring device can sense the event and pull down an alert# pin, trigger a corresponding driver in the BMC to enter an interrupt context, and further send a SIGIO signal to a corresponding monitoring thread to wake up the SIGIO signal.
After the awakened monitoring thread can read the monitoring data and the upper and lower limit data (namely the monitoring threshold value) of the monitoring device, if the monitoring data is found to exceed the preset monitoring threshold value, the monitoring main thread in dormancy is awakened through the condition variable, and after the monitoring main thread is awakened, the subsequent work such as alarm and corresponding adjustment actions can be finished according to the specific reporting event type.
It should be noted that, the method provided in this embodiment obtains a good effect in multiple projects based on OpenBMC (an open source BMC scheme), and can use yopto (an open source community) to manage project projects, and send the monitoring process of the user space to system d (init software under a linux system) to manage; commands to start and stop the monitoring process may be # sudo systemctl start hwmon.service and # sudo systemctl stop hwmon.service, respectively.
In the embodiment of the invention, by acquiring the overrun signal sent by the monitoring device, the working of capturing the overrun event is carried out by the monitoring device at the bottommost layer by utilizing the hardware resource advantage of the monitoring device, so that the monitoring device is accurately monitored in real time by using asynchronous IO instead of the existing polling scheme, the scheduling pressure of the BMC is reduced, and the response speed of the system process is ensured.
