Detailed Description
The core of the application is to provide a data transmission method, a data transmission device, a terminal device and a computer readable storage medium of a baseboard management controller, so as to improve the utilization rate of data transceiving cache.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all 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 application.
In the related art, different bandwidth occupied by different operation commands is different and required buffer space is also different when communication is performed. For example, when the transmission parameter is configured, the state acquisition can be completed only by one request reply, and the required bandwidth and the cache space are very small. Firmware upgrade requires a large amount of data to be transmitted, and requires a large bandwidth and a large cache space. However, in chip design, the data transceiving buffer capacity of the MCTP module is usually designed to be a fixed size and to be small. If the buffer capacity is increased, the occupied area is increased, and the cost is increased.
Therefore, the application provides a data transmission method of a baseboard management controller, which judges whether a difference value between a data volume of a sending channel and a data volume of a receiving channel is greater than a threshold value in a data receiving and sending process, if so, adjusts a distribution proportion of a shared cache, avoids that cache resources of another channel are wasted due to a large data volume of a single channel, improves a utilization rate of a cache system in a data transmission process, avoids resource waste, and reduces hardware cost.
The following describes a data transmission method of a baseboard management controller according to an embodiment.
Referring to fig. 1, fig. 1 is a flowchart illustrating a data transmission method of a bmc according to an embodiment of the present disclosure.
In this embodiment, the method may include:
s101, setting the distribution ratio of a sending channel and a receiving channel in a shared cache of a data transceiving cache as a default distribution ratio;
the step aims to set the distribution ratio of the sending channel and the receiving channel in the shared cache of the data transceiving cache as the default distribution ratio. That is, the allocation ratio is first set to the shared buffer in the data transceiving buffers. The allocation ratio may control the ratio of allocation to the sending channel and the receiving channel in the shared buffer. For example, if the distribution ratio is 5: and 5, half of the shared buffer is allocated to the transmitting channel, and the remaining half of the shared buffer is allocated to the receiving channel. The data transceiving buffer is a storage module which is positioned in the MCTP controller and is used for carrying out data transceiving buffer, and the size of the data transceiving buffer determines the size of the data volume which can be processed under the same unit. The larger the data transceiving buffer is, the more efficient the data transceiving processing is.
Generally, in the prior art, the buffer size of the data transceiving buffer is fixed for the classification of the transmitting channel and the receiving channel. When the data volume of the sending channel is far larger than that of the receiving channel, the cache corresponding to the receiving channel is not effectively utilized, and the utilization rate is reduced.
Further, the data transceiving caching in this step includes: a sending private cache, a receiving private cache, and a shared cache. As can be seen, the data transceiving cache used in this embodiment includes a sending private cache, a receiving private cache, and a shared cache.
Wherein, the buffer sizes of the transmitting private buffer and the receiving private buffer can be set to be smaller. For example, the size of the capacity used for transmitting the parameter configuration packet may be set.
S102, when data transceiving operation is executed, whether a difference value between the data volume of the sending channel and the data volume of the receiving channel is larger than a threshold value is judged;
on the basis of S101, this step is intended to determine whether or not a difference between the data amount of the transmission channel and the data amount of the reception channel is larger than a threshold when the data transceiving operation is performed. It can be seen that, in this step, it is determined whether the transmission channel or the reception channel is much larger than the other data channel. If yes, it indicates that the channel needs more caches, and the allocation ratio needs to be adjusted when the cache of another channel cannot be fully utilized.
Further, the step may include:
step 1, when data transceiving operation is executed, command quantity detection is carried out on a sending channel and a receiving channel to obtain the command quantity of the sending channel and the command quantity of the receiving channel;
and 2, judging whether the difference value between the data volume of the sending channel and the data volume of the receiving channel is larger than a threshold value or not based on the command number of the sending channel and the command number of the receiving channel.
It can be seen that the present alternative scheme mainly illustrates how it is determined whether the allocation ratio needs to be adjusted. In this alternative, when performing data transceiving operation, performing command number detection on the sending channel and the receiving channel to obtain the command number of the sending channel and the command number of the receiving channel, and determining whether a difference between the data amount of the sending channel and the data amount of the receiving channel is greater than a threshold value based on the command number of the sending channel and the command number of the receiving channel.
S103, if yes, adjusting the distribution proportion of the sending channel and the receiving channel in the shared cache;
on the basis of S102, this step is intended to adjust the allocation ratio of the sending channel and the receiving channel in the shared buffer when the difference between the data amount of the sending channel and the data amount of the receiving channel is greater than the threshold. I.e. a corresponding adjustment is made.
Further, the adjusting process in this step may include:
and when the data volume of the sending channel is larger than that of the receiving channel, performing increment processing on the proportion number of the sending channel in the distribution proportion.
It can be seen that the present alternative scheme mainly explains how to adjust when the data volume of the transmission channel is large. In this alternative, when the data amount of the transmission channel is greater than the data amount of the reception channel, the proportional number of the transmission channel in the allocation proportion is subjected to incremental processing. That is, when the data amount of the transmission channel is large, the proportional number of the transmission channels in the allocation proportion is increased. For example, from 5: the ratio of 5 can be varied to 7:3, in a ratio of the total weight of the composition.
Further, if the data volume of the transmitting channel is still larger than the data volume of the receiving channel after the preset time period, the adjustment can be continued on the basis of the adjustment. For example, the ratio may be from 7:3, adjusting to 9:1. in order to provide maximum bandwidth for timely transmission of data when the number of transmit channels is continuously at a higher data volume.
Further, the adjusting process in this step may include:
and when the data volume of the sending channel is smaller than that of the receiving channel, performing increment processing on the proportion number of the receiving channels in the distribution proportion.
It can be seen that the present alternative scheme mainly illustrates how to adjust when the data volume of the receiving channel is large. In this alternative, when the data amount of the receiving channel is greater than that of the transmitting channel, the proportional number of the receiving channel in the allocation proportion is subjected to incremental processing. That is, when the data amount of the reception channel is large, the proportional number of the reception channels in the allocation proportion is increased. For example, from 5: the ratio of 5 can be varied to 7:3, in a ratio of the total weight of the composition.
Further, if the data volume of the receiving channel is still larger than the data volume of the transmitting channel after the preset time period, the adjustment can be continued on the basis of the adjustment. For example, the ratio may be from 7:3, adjusting to 9:1. in order to provide maximum bandwidth for transmitting data in time when the number of receiving channels is continuously at a higher data volume.
Further, this embodiment may further include:
and when the data volume of the sending channel and the data volume of the receiving channel are both smaller than the preset values, adjusting the distribution ratio of the sending channel and the receiving channel in the shared cache to the default distribution ratio.
It can be seen that, in this alternative scheme, it is mainly explained that, when the sending channel and the receiving channel are both in a smaller data amount, the allocation ratio of the sending channel and the receiving channel in the shared buffer is adjusted to the default allocation ratio. That is, when the data amount is low, the default allocation ratio is switched to, so that the buffers corresponding to the sending channel and the receiving channel are balanced to cope with the change of the burst data amount.
And S104, executing data transceiving operation based on the adjusted shared cache.
On the basis of S103, this step is intended to perform data transceiving operation based on the adjusted shared cache. That is, on the basis of the sending private buffer and the receiving private buffer, data transceiving operation is performed based on the shared buffer with the adjusted proportion.
The embodiment may further include:
when transmitting and receiving the short data packet, the data transmitting and receiving operation is carried out based on the shared cache of the default distribution proportion.
It can be seen that when sending and receiving a short packet, the shared cache based on the default allocation ratio performs the data sending and receiving operation. The short packet is a packet with a small data amount. A parameter configuration packet or a message packet may be included.
In addition, in this embodiment, it may also be determined whether the data amount of the channel with the larger data amount is recovered to the normal level after a period of time after the data transceiving operation is performed. If so, the allocation ratio may be adjusted to the default allocation ratio.
The default classification proportion can be equal division of two channels, and the proportion value of a certain channel can be adjusted to a higher position based on the actual data receiving and sending conditions. For example, the default allocation ratio may be set to 6:4.
in summary, in the process of data transceiving, in this embodiment, it is determined whether a difference between the data amount of the sending channel and the data amount of the receiving channel is greater than a threshold, and if so, the allocation ratio of the shared cache is adjusted, so that it is avoided that a cache resource of another channel is wasted due to a large data amount of a single channel, the utilization rate of the cache system in the data transmission process is improved, resource waste is avoided, and hardware cost is reduced.
The following further describes a data transmission method of a baseboard management controller according to another embodiment.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a bmc according to an embodiment of the present disclosure.
In this embodiment, the related hardware system is composed of a BMC and other devices or apparatuses, and the BMC is connected to the apparatuses through a PCIe (peripheral component interconnect express) or I2C (Inter-Integrated Circuit) bus. The BMC chip system at least comprises a Central Processing Unit (CPU), a memory and an MCTP controller.
Referring to fig. 3, fig. 3 is a schematic structural diagram of an MCTP controller according to an embodiment of the present disclosure.
Therefore, the MCTP controller consists of five parts, including a system bus interface, a control register, a data cache controller, a data packet transceiver controller and an interface control module.
The system bus interface is used for communication between the CPU and the MCTP controller, and comprises parameter configuration, state acquisition, module working switch, data transceiving and the like.
The control register is used for realizing parameter configuration and the internal working state of the storage module.
The data cache controller realizes the cache of the transceiving data and the adjustment control of the cache allocation. And the buffer allocation is automatically adjusted in real time according to the type of the receiving and sending command, the receiving and sending data volume and the like.
The data packet receiving and transmitting controller is used for realizing the receiving and transmitting functions of the MCTP data packet, and comprises the steps of generating the MCTP data packet and analyzing and checking the MCTP data packet.
The interface control module is used for controlling an external bus interface to realize data receiving and transmitting.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a data transceiving cache according to an embodiment of the present application.
In this embodiment, the data transceiving cache is divided into three parts:
1) And sending a private cache with the size of N, and sending a channel special cache.
2) And receiving a private cache with the size of N, and receiving a channel special cache.
3) Shared cache, dynamically allocatable cache area, total size is M.
And under the default state, the shared buffer area is averagely distributed to the sending channel and the receiving channel. The data sending buffer and the data receiving buffer are equal in size.
When the data flow of the sending channel is large, the data flow of the receiving channel is small. And adjusting the distribution proportion of the shared buffer area, wherein the data sending buffer is larger than the data receiving buffer.
And when the data flow of the sending channel is small and the data flow of the receiving channel is large. And adjusting the distribution proportion of the shared buffer area, wherein the data sending buffer is smaller than the data receiving buffer.
Further, the steps of this embodiment may include:
step 1, the equipment is powered on and started, and the MCTP module is automatically matched and connected on the MCTP bus.
And 2, initializing and configuring an MCTP module by system software, and configuring the distribution proportion of the transceiving cache by the system software aiming at the MCTP data cache controller. Here, the distribution ratio is assumed to be 5
And 3, starting normal data receiving and transmitting operation by the system software.
And 4, when only brief data packets such as parameter configuration, state acquisition and the like exist in communication, the data cache controller does not take measures and the cache allocation proportion is unchanged.
And step 5, when the sending data volume is larger than the receiving data volume in the communication, or the data cache controller detects a command of sending a large amount of data. The data cache controller will automatically adjust the cache allocation ratio.
Step 6, firstly, the ratio of the sending buffer to the receiving buffer is adjusted to 7.
And 7, monitoring the size of the residual space of the transceiving cache region in real time in the system work. When the remaining space of the sending buffer gradually decreases and the remaining space of the receiving buffer is substantially unchanged, the ratio of the sending buffer to the receiving buffer is continuously increased, for example, 8:2.
when the remaining space of the sending buffer is basically unchanged and the remaining space of the receiving buffer is gradually reduced, the ratio of the sending buffer to the receiving buffer is continuously reduced.
This process continues until the ratio of transmit buffer to receive buffer is 10, with no room for adjustment.
In step 8, when receiving a large amount of data, the principle of buffer allocation is substantially the same as the process described in step 5 to step 7.
And 9, when the bidirectional flow monitored by the cache control module is low after the end of receiving and transmitting a large amount of data, adjusting the ratio of the transmitting cache to the receiving cache to 5.
In this embodiment, whether the difference between the data amount of the sending channel and the data amount of the receiving channel is greater than the threshold may be determined in the data transceiving process, and if so, the allocation proportion of the shared cache is adjusted, thereby avoiding that the cache resource of another channel is wasted due to a large data amount of a single channel, improving the utilization rate of the cache system in the data transmission process, avoiding wasting the resource, and reducing the hardware cost.
