Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic diagram illustrating a connection relationship between a BMC chip and a node device in a server system, where as shown in fig. 1, the BMC chip is connected to a plurality of node devices 11 in the server system through a plurality of I/O interfaces (i.e., input/output interfaces) 10 provided in the BMC chip. That is to say, the BMC chip may be connected to multiple node devices of one computing node in the server system through multiple self-contained I/O interfaces, so as to implement monitoring and management of the BMC chip on the multiple node devices of one computing node.
The BMC chip can send a command to the node device through the I/O interface to realize data transmission between the BMC chip and the node device. For example, the BMC chip may output a data acquisition command to the node device 11 through the I/O interface 10, and after the node device 11 responds to the data acquisition command, the node device inputs its own status data to the BMC chip through the I/O interface 10, so that the BMC chip monitors and manages the node device 11 according to the status data.
When the computing density of the server system is not high, the BMC chip can meet the supervision requirement on a single computing node through an I/O interface of the BMC chip because the number of node devices which need to be managed by each computing node is small. However, with the increase of computing power of the computing nodes and the increase of computing density of the server, node devices of a single computing node, such as power devices and heat dissipation devices, become more and more complex, and the number of the node devices to be managed in the single computing node becomes more and more, so that the number of I/O interfaces of the BMC chip cannot meet the connection requirement of the single computing node.
Based on this, an interface expansion scheme is provided in an embodiment of the present invention, so that a first device (e.g., a BMC chip) having multiple interfaces (e.g., I/O interfaces) is connected to a second device (e.g., a BMC chip) to perform interface expansion on the second device (e.g., the BMC chip), so that the second device (e.g., the BMC chip) can meet the number requirement of the interfaces.
As an optional implementation of the disclosure of the present invention, an embodiment of the present invention provides an interface expansion method, which may be applied to a first device, to implement interface expansion of a second device (e.g., a BMC chip) through the first device.
As shown in fig. 2, fig. 2 is a schematic diagram of a connection relationship between a first device and a second device according to an embodiment of the present invention, the first device 21 is connected to the second device 22, the first device 21 includes a plurality of interfaces 211 and a register 210, and the plurality of interfaces 211 may be connected to a plurality of third devices 23, respectively.
In some embodiments of the present invention, all of the plurality of interfaces 211 may be I/O interfaces, but the present invention is not limited thereto, and in other embodiments, the plurality of interfaces 211 may also be other data transmission interfaces, such as USB interfaces. The first device 21 and the second device 22 may be connected through interfaces such as SPI and IIC, which are not described herein again.
In some optional examples, the first device 21 and the second device 22 are connected through an IIC interface, and the second device 22 issues a command to the first device 21 through an IIC data bus. And the first device 21 or a processor or a control module inside the first device 21 may be a slave device of the IIC to execute the command issued by the second device 22.
In some embodiments of the present invention, the second Device 22 includes a BMC chip, the first Device 21 includes a Programmable Logic Device, such as a CPLD (Complex Programmable Logic Device) or an FPGA (Field Programmable Gate Array), and the third Device 23 includes a node Device in a server system, which may include a blade server, a power supply module, a fan module, and the like.
The third devices 23 connected by different interfaces 211 may be different devices, for example, the third device 23 connected by one interface 211 may be a power module, and the third device 23 connected by another interface 211 may be a fan module.
Of course, the present invention is not limited to this, in other embodiments, the second device 22 may also be other devices that need to extend an interface, such as a processor chip, etc., the first device 21 may also be other processors, microprocessors, or single-chip microcomputers, etc., and the third device 23 may also be other devices or interfaces that need to perform data transmission with the second device 22, etc.
Fig. 3 is a flowchart of an interface expanding method according to an embodiment of the present invention, and as shown in fig. 3, the interface expanding method includes:
s301: receiving a command sent by the second device 22, where the command is used to control execution of a data transfer operation between the second device 22 and a target interface, where the target interface is any interface in the plurality of interfaces;
referring to fig. 2 and 4, fig. 4 is a flowchart of an interface expanding method according to another embodiment of the present invention, when the second device 22 needs to send data to the target device or needs to acquire data of the target device, as shown in step S401 in fig. 4, the second device 22 sends a command to the first device 21, where the command is used to control the first device 21 to execute a data transmission operation between the second device 22 and the target interface. The target device is any one or more third devices 23, and the target interface is an interface connected to the target device in the plurality of interfaces 211.
It is understood that, if the plurality of interfaces 211 are all I/O interfaces, the data transfer operation includes a first data transfer operation and a second data transfer operation, the first data transfer operation is used for transferring data sent by the second device 22 to the target interface so as to transfer the data to the third device 23 connected thereto through the target interface, and the second data transfer operation is used for transferring data input by the target interface to the second device 22, where the data input by the target interface is data of the third device 23 connected thereto.
For example, when the second device 22 needs to send data to the third device 23, the second device 22 sends a command to the first device 21 to control the first device 21 to execute a first data transmission operation between the second device 22 and a target interface, i.e., the interface 211; when the second device 22 needs to acquire the data of the third device 23, the second device 22 sends a command to the first device 21 to control the first device 21 to perform a second data transmission operation between the second device 22 and a target interface, i.e., the interface 211.
S302: determining a target register having a mapping relation with a target interface; the mapping relation is used for enabling the data stored in the target register to correspond to the data transmitted by the target interface;
after receiving the command sent by the second device 22, the first device 21 parses the command, determines a target interface according to a result of the parsing, and then determines a target register having a mapping relationship with the target interface as shown in step S402 in fig. 4. The mapping relationship is used for enabling the data stored in the target register and the data transmitted by the target interface to correspond to each other. Wherein the destination register may be register 210.
It should be noted that the mapping relationship between the target register and the target interface is preset. In some alternative examples, the execution of the mapping may be controlled by a control module in the first device 21. For example, if the data stored in the target register changes, the control module may control the data transmitted by the target interface to change correspondingly; if the data transmitted by the target interface changes, the control module controls the data stored in the target register to change correspondingly, so that the data stored in the target register and the data transmitted by the target interface correspond to each other.
It will be appreciated that the control module may be a program or set of instructions or the like pre-integrated in the processor of the first device 21. The control module can realize mutual correspondence of data between the target interface and the target register based on a Map protocol.
S303: read and write operations are performed on the target register to perform data transfer operations between the second device 22 and the target interface.
After determining the target register having a mapping relationship with the target interface, as shown in step S403 in fig. 4, the first device 21 may determine to perform a write operation or a read operation on the target register according to the command parsing result.
If it is determined that the write operation is performed on the destination register, the first device 21 changes the data stored in the destination register by writing new data into the destination register, and then changes the data output by the corresponding destination interface based on the mapping relationship, as shown in step S404 in fig. 4. Thereafter, as shown in step S405 in fig. 4, the target interface may transmit the corresponding data to the third device 23 connected thereto. Based on this, a first data transfer operation of transferring data sent by the second device 22 to the target interface may be implemented.
Wherein the new data written to the destination register may be obtained by parsing the command sent by the second device 22. Of course, the new data written into the target register may also be sent in a bundle with the command, i.e. the command does not need to be parsed, and the new data written into the target register may also be obtained.
If it is determined that a read operation is performed on the target register, the first device 21 reads the data stored in the target register, as shown in step S406 in fig. 4. Since the target register and the target interface have a mapping relationship, the data stored in the target register corresponds to the input data of the target interface, that is, the data corresponding to the input data of the target interface, which is the data of the third device 23 input by the target interface, is read by the first device 21. Thereafter, as shown in step S407 in fig. 4, the first device 21 may send the read data to the second device 22, so that the second device 22 obtains the input data of the target interface according to the read data, and further obtains the data of the third device 23 connected to the target interface. Based on this, a second data transfer operation of transferring data input by the target interface to the second device 22 can be realized.
The first device 21 may directly send the read data of the target register to the second device 22, or may convert the read data of the target register into input data of the target interface and send the input data of the target interface to the second device 22, which is not described herein again.
Based on this, in some embodiments of the present invention, performing the read/write operation on the target register to perform the data transfer operation between the second device and the target interface includes: and executing a write operation on the target register, writing the data sent by the second device 22 into the target register to execute a first data transfer operation of transferring the data sent by the second device 22 to the target interface, and enabling the target interface to output the corresponding data.
On this basis, in other embodiments of the present invention, performing a read/write operation on the target register to perform a data transfer operation between the second device and the target interface includes: a read operation is performed on the target register to read data corresponding to the input data of the target interface and the read data is transmitted to the second device 22 to perform a second data transmission operation of transmitting the input data of the target interface to the second device 22.
Because the first device 21 can execute the data transmission operation between the second device 22 and the target interface according to the command sent by the second device 22, the interface of the first device 21 can realize the same data transmission function as the interface of the second device 22, so that the interface of the second device 22 can be expanded through the first device 21, the problem that the number of the interfaces carried by the second device 22 cannot meet the requirement can be solved, the interface does not need to be expanded by developing the second device 22, the development cost can be reduced, and the application range of the second device 22 can be expanded. For example, the BMC chip with the interface expanded by the first device 21 may be applied to a two-way, four-way, eight-way, and high-integration server architecture.
Also, since the target register and the target interface have a mapping relationship for making data of the target register and data transferred by the target interface correspond to each other, after the first device 21 determines the target register having a mapping relationship with the target interface, it is possible to perform a data transfer operation between the second device 22 and the target interface by performing a read/write operation on the target register. Since the transmission data of the target interface is changed in real time, compared with directly acquiring the transmission data of the target interface, acquiring the data corresponding to the target interface cached by the target register can ensure the accuracy and correctness of the data, and thus can ensure the accuracy and correctness of data transmission between the second device 22 and the target interface.
It should be noted that the first device 21 may also control the input/output state of the target interface according to a command sent by the second device 22. For example, if the command sent by the second device 22 is used to control the first device 21 to perform a first data transmission operation for transmitting data sent by the second device 22 to the target interface, the first device 21 controls the data transmission mode of the target interface to be the output mode. If the command sent by the second device 22 is used to control the first device 21 to perform a second data transmission operation for transmitting the data of the target interface to the second device 22, the first device 21 controls the data transmission mode of the target interface to be the input mode.
Of course, the present invention is not limited to this, and in other embodiments, the first device 21 may control the data transmission mode of the target interface to be the output mode only in the process that the target interface outputs the data sent by the second device 22, and control the data transmission mode of the target interface to be the input mode in other periods after the transmission of the target interface is completed.
In some embodiments of the present invention, different target interfaces may have a mapping relationship with different target registers, that is, the transmission data of the multiple interfaces of the first device 21 may correspond to the data of the multiple registers inside the first device 21, respectively, but the present invention is not limited thereto, and in other alternative embodiments, different target interfaces may have a mapping relationship with different bits of the same target register, that is, the transmission data of the multiple interfaces of the first device 21 may correspond to the data of the multiple bits of one register inside the first device 21, respectively.
Based on this, in some embodiments of the present invention, determining the target register having a mapping relationship with the target interface comprises: determining a target register corresponding to the data of the corresponding bit and the transmission data of the target interface; the data of different bits of the target register corresponds to the transmission data of different interfaces. That is, after the target interface is determined, if data of a corresponding bit in one register corresponds to transfer data of the target interface, the register may be determined as the target register.
It should be noted that, in some alternative embodiments, one bit of data may correspond to transmission data of one interface, or multiple bits of data may correspond to transmission data of one interface. In the embodiment of the present invention, only one bit of data is described as corresponding to one interface of transmission data, but the present invention is not limited thereto.
In some optional embodiments, the data of one bit and the transmission data of the target interface correspond to each other, including: if the data of the bit is first data, the output data of the target interface is second data; if the data of the bit is third data, the output data of the target interface is fourth data; if the input data of the target interface is second data, the data of the bit is first data; if the input data of the target interface is the fourth data, the data of the bit is the third data.
Wherein the first data may include a logic 1, the second data may include high level data, the third data may include a logic 0, and the fourth data may include low level data. Of course, the present invention is not limited thereto, and in other alternative examples, the first data may also include a logic 1, the second data may also include a low level data, the third data may also include a logic 0, and the fourth data may also include a high level data, which is not described herein again.
When the first data is a logic 1, the second data is a high level data, the third data is a logic 0, and the fourth data is a low level data, if a logic 1 is written into a bit corresponding to the target register, the first device 21 controls the target interface having a mapping relationship with the bit to output the high level data, and if a logic 0 is written into a bit corresponding to the target register, the first device 21 controls the target interface having a mapping relationship with the bit to output the low level data.
If the data read from the bit corresponding to the target register is logic 1, the second device 22 may determine that the data currently transmitted by the target interface having a mapping relationship with the bit is high-level data, and if the data read from the bit corresponding to the target register is logic 0, the second device 22 may determine that the data currently transmitted by the target interface having a mapping relationship with the bit is low-level data.
In the embodiment of the present invention, not only the normal data transmission between the second device 22 and the third device 23 can be realized, but also the state of the third device 23 can be monitored by monitoring the interface connected to the third device 23. On this basis, the interface expanding method in some embodiments of the present invention further includes:
detecting input data of any interface connected to the third device 23;
if the input data of the interface includes abnormal data, sending feedback information to the second device 22, so that the second device 22 obtains the input data of the interface, and determining the state of the third device 23 connected with the interface according to the input data.
The abnormal data includes data representing an abnormality of a pin signal of the interface or data representing an abnormality of an operating state of the third device 23. That is, during normal operation of the third device 23, input data of the interface connected to the third device 23 is normal. For example, during normal operation of the third device 23, the input data of the interface connected thereto is always high level data or low level data. If the input data of the interface changes from high level data to low level data, or changes from low level data to high level data, or the interface has no input data, it indicates that the input data of the interface includes abnormal data, which may indicate that the pin signal of the interface is abnormal, and may also indicate that the operating state of the third device 23 is abnormal.
After the first device 21 sends the feedback information to the second device 22, the second device 22 sends a command to the first device 21, and controls the first device 21 to send the input data including the abnormal data of the interface to the second device 22, so that the second device 22 determines an abnormal condition according to the abnormal data in the input data and manages the abnormal condition. The feedback information may be an interrupt instruction or the like.
Based on this, in the process of operating the third device 23, the first device 21 may assist the second device 22 in monitoring the state of the third device 23 by detecting the input data of the interface and determining whether the input data includes abnormal data.
Although the data in the destination register and the transfer data of the destination interface correspond to each other, when the transfer data of the destination interface includes abnormal data, the transfer data is changed, and therefore, the data in the destination register is overwritten with new data. Based on this, after the first device 21 detects that the input data of the interface contains abnormal data, the input data containing abnormal data may be saved in a memory or other register for later retrieval of a call.
As another optional implementation of the disclosure, the embodiment of the present invention further provides an interface expanding method, where the interface expanding method may be applied to the second device 22. Fig. 2 and the related description are referred to for connection relationship between the second device 22 and the first device 21, and are not repeated here.
Fig. 5 is a flowchart of an interface expanding method according to another embodiment of the present invention, and as shown in fig. 5, the interface expanding method includes:
s501: generating a command for controlling the first device 21 to perform a data transfer operation between the second device 22 and a target interface, the target interface being any interface of the plurality of interfaces;
the second device 22 may be set in advance, so that the second device 22 generates a corresponding command in a specific situation, or the second device 22 may generate a command periodically to send data to the third device 23 periodically or to acquire data of the third device 23 periodically. Further, the operator may send an instruction to the second device 22 through a host or the like connected to the second device to cause the second device 22 to generate a corresponding command.
S502: sending a command to the first device 21, so that the first device 21 determines a target register having a mapping relationship with a target interface, and performs a read-write operation on the target register to perform a data transfer operation between the second device 22 and the target interface; the mapping relation is used for enabling the data of the target register and the data transmitted by the target interface to correspond to each other.
