Description

Technical Field

[0001] This invention relates to the field of computer technology, and in particular to a video transcoding card connection method, apparatus, device, and medium. Background Technology

[0002] Currently, with the continuous development of high-performance servers, industries such as artificial intelligence, facial recognition, live streaming, and e-commerce live streaming have experienced rapid updates in recent years, greatly satisfying people's visual needs. These rapid technological advancements are closely related to the continuous development of video transcoding cards. Considering versatility and compatibility, video transcoding cards are typically half-height, half-length PCIe (PCIe Standard, High-Speed ​​Serial Computer Expansion Bus) cards. Current high-performance servers commonly employ 4-way or even 6-way and 8-way accelerator card designs. Video transcoding cards interact with the server CPU via a PCIe link, handling massive amounts of data. If multiple video transcoding cards within the server operate simultaneously for extended periods, there is a probability that the transcoding cards will fail to send CPL (ConvErsE Position Logical) data packets back to the CPU within the specified time, causing a PCIe link CPL error. If the CPU continues to access the video transcoding card after a PCIe CPL error, it will cause an error on the CPU side, triggering a system crash. This can result in incalculable reputational and economic losses for the company and its actual business operations.

[0003] As can be seen from the above, how to avoid system crashes caused by CPU errors and resulting in loss of business data during the connection process of video transcoding cards, and how to improve the stability of video transcoding card operation in servers are problems that need to be solved in this field. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a video transcoding card connection method, apparatus, device, and medium, which can effectively avoid system crashes caused by CPU errors, resulting in data loss and improving the stability of video transcoding card operation in servers. The specific solution is as follows:

[0007] If no data packet is received from the video transcoding card within the preset period, the video transcoding card will be identified as an abnormal video transcoding card and an error message will be generated.

[0008] Based on the error message, the I2C bus number of the abnormal video transcoding card is determined, and the I2C bus number is sent to the local baseboard management controller, so that the baseboard management controller can send a cold start processing request to the abnormal video transcoding card based on the I2C bus number.

[0016] Optionally, the baseboard management controller sends a cold start processing request to the abnormal video transcoding card based on the I2C bus number, including:

[0018] Optionally, before obtaining the processed power signal information sent by the abnormal video transcoding card through the baseboard management controller, the method further includes:

[0019] After processing, the virtual reality chip in the abnormal video transcoding card sets its own normal power signal to a high level and generates power signal information. It then sends the power information to the programmable chip, so that the programmable chip can send the power information to the baseboard management controller.

[0020] Optionally, before re-establishing the connection with the processed abnormal video transcoding card, the method further includes:

[0021] Set the normal power signal to low level;

[0022] After the baseboard management controller obtains the processed low-level power signal information sent by the abnormal video transcoding card, it sets the low-level normal power signal to a high level.

[0023] Optionally, after re-establishing the connection with the processed abnormal video transcoding card, the method further includes:

[0029] The video transcoding card connection module is used to re-establish the connection with the processed abnormal video transcoding card after obtaining the power signal information sent by the processed abnormal video transcoding card through the baseboard management controller.

[0030] Thirdly, this application discloses an electronic device, including:

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Currently, with the continuous development of high-performance servers, industries such as artificial intelligence, facial recognition, live streaming, and e-commerce live streaming have rapidly evolved in recent years, greatly satisfying people's visual needs. These rapid technological advancements are closely related to the continuous development of video transcoding cards. Considering versatility and compatibility, video transcoding cards are typically half-height, half-length PCIe (PCIe Component Integrated Int ErconnEct Express, a high-speed serial computer expansion bus standard) cards. Current high-performance servers commonly employ 4-way, 6-way, or even 8-way accelerator card designs. Video transcoding cards interact with the server CPU via the PCIe link, exchanging massive amounts of data. If multiple video transcoding cards within the server operate simultaneously for extended periods, there is a probability that the video transcoding cards will fail to send CPL (Converter Position Logical) data packets back to the CPU within the specified time, causing PCIe link CPL errors. If the CPU continues to access the video transcoding card after a PCIe CPL error, it will cause CPU-side errors, triggering system crashes and resulting in incalculable reputational and economic losses for the company and its business operations. As can be seen from the above, how to avoid system crashes caused by CPU errors and resulting in loss of business data during the connection process of video transcoding cards, and how to improve the stability of video transcoding card operation in servers are problems that need to be solved in this field.

[0044] Currently, existing technologies lack processing logic. After the video transcoding card reports a CTO error, the motherboard CPU continues to read and write to the card via the PCIe link, triggering a CPU-side TOR Timeout error, which in turn causes a CPU IERR error, ultimately leading to system crashes. This results in insufficient robustness of the entire server system, causing serious losses such as data loss after a crash. This application proposes a system and method for stable operation of a video transcoding card within a high-performance server, preventing server system crashes and improving the robustness of high-performance servers. Building upon existing solutions, this invention adds optimization measures after a video transcoding card CPL error. By locating and resetting the problematic video transcoding card, system crashes are avoided without affecting actual business operations.

[0045] See Figure 1As shown in the figure, an embodiment of the present invention discloses a video transcoding card connection method, which may specifically include:

[0046] Step S11: Determine whether data packets sent by the video transcoding card have been received within the preset period.

[0047] In this embodiment, before determining whether a data packet sent by the video transcoding card has been obtained within a preset period, the method further includes: connecting the preset PCIe Slot of the server to the video transcoding card; establishing a PCIe link with the system-on-a-chip in the video transcoding card; and establishing an I2C link between the local baseboard management controller and the programmable chip in the video transcoding card.

[0048] Step S12: If no data packet is received from the video transcoding card within the preset period, the video transcoding card is identified as an abnormal video transcoding card, and an error message is generated.

[0049] Step S13: Determine the I2C bus number of the abnormal video transcoding card based on the error information, and send the I2C bus number to the local baseboard management controller so that the baseboard management controller can send a cold start processing request to the abnormal video transcoding card based on the I2C bus number.

[0050] In this embodiment, after the I2C bus number is sent to the local baseboard management controller, the baseboard management controller uses the I2C link and sends a video transcoding card restart request to the programmable chip in the abnormal video transcoding card based on the I2C bus number, so that the programmable chip can restart the abnormal video transcoding card by controlling the power state of the virtual reality chip in the abnormal video transcoding card.

[0051] Step S14: After obtaining the processed power signal information sent by the abnormal video transcoding card through the baseboard management controller, re-establish the connection with the processed abnormal video transcoding card.

[0052] In this embodiment, before obtaining the processed power signal information sent by the abnormal video transcoding card through the baseboard management controller, the method further includes: the virtual reality chip in the processed abnormal video transcoding card sets its own normal power signal to a high level and generates power signal information, and sends the power information to the programmable chip, so that the programmable chip sends the power information to the baseboard management controller.

[0053] In this embodiment, the baseboard management controller obtains the processed power signal information sent by the abnormal video transcoding card, then sets the normal power signal to a low level. After obtaining the processed low-level power signal information sent by the abnormal video transcoding card, the baseboard management controller sets the low-level normal power signal to a high level, and then determines a new PCIe link with the system-on-a-chip in the video transcoding card, so as to use the new PCIe link for PCIe data interaction and service script execution.

[0054] This application is applied to the CPU in a server. The CPU determines whether it receives data packets sent by the video transcoding card within a preset period. If no data packets are received within the preset period, the video transcoding card is identified as abnormal, and an error message is generated. Based on the error message, the I2C Bus NumbEr of the abnormal video transcoding card is determined. Then, the CPU stops PCIe read / write operations on the video transcoding card in the same slot as the abnormal one to prevent the problem from worsening and causing system crashes. The I2C Bus NumbEr is then sent to the local BMC (BasEboard). The Motherboard Management Controller (BMC) uses the I2C link and, based on the I2C bus number, sends a video transcoding card restart request to the programmable chip in the abnormal video transcoding card. The programmable chip then controls the power state of the virtual reality chip in the abnormal video transcoding card to restart it. After restarting, the virtual reality chip in the abnormal video transcoding card sets its normal power signal to a high level. The programmable chip generates power signal information and transmits this information to the Motherboard Management Controller via the I2C link. The CPU pulls the PERST signal of the abnormal video transcoding card slot low for a period of time. After receiving the processed low-level power signal information from the abnormal video transcoding card through the Motherboard Management Controller, it sets the low-level normal power signal to a high level and determines a new PCIe link with the system-on-a-chip in the video transcoding card. This new PCIe link is then used for PCIe data interaction and business script execution.

[0055] In this embodiment, it is determined whether data packets sent by the video transcoding card are received within a preset period. If no data packets are received within the preset period, the video transcoding card is identified as an abnormal video transcoding card, and an error message is generated. Based on the error message, the I2C bus number of the abnormal video transcoding card is determined, and the I2C bus number is sent to the local baseboard management controller. The baseboard management controller then sends a cold start processing request to the abnormal video transcoding card based on the I2C bus number. After the baseboard management controller obtains the processed power signal information sent by the abnormal video transcoding card, it re-establishes the connection with the processed abnormal video transcoding card. This application determines whether data packets sent by the video transcoding card are received within a preset period. If no data packets are received, an error message is generated to perform cold start processing and re-establish the connection with the processed abnormal video transcoding card. This effectively avoids system crashes caused by CPU errors, resulting in data loss, and improves the stability of the video transcoding card operation in the server.

[0056] See Figure 2 As shown in the figure, an embodiment of the present invention discloses a video transcoding card connection method, which may specifically include:

[0057] Step S21: Determine whether data packets sent by the video transcoding card have been received within the preset period.

[0058] Step S22: If no data packet is received from the video transcoding card within the preset period, the video transcoding card is identified as an abnormal video transcoding card, and an error message is generated.

[0059] Step S23: Determine the PCIE bus number of the abnormal video transcoding card based on the error information, and then disable the PCIE link between the video transcoding card and the system-on-a-chip based on the PCIE bus number.

[0060] Step S24: Determine the I2C bus number of the abnormal video transcoding card based on the error information, and send the I2C bus number to the local baseboard management controller so that the baseboard management controller can send a cold start processing request to the abnormal video transcoding card based on the I2C bus number.

[0061] Step S25: After obtaining the processed power signal information sent by the abnormal video transcoding card through the baseboard management controller, re-establish the connection with the processed abnormal video transcoding card.

[0062] For example, such as Figure 3The diagram shows the connection between each video transcoding card and the server motherboard. Each transcoding card is connected to the PCIe Slot (PCIe standard slot) of the server motherboard via gold fingers, and obtains P12V power from the server motherboard. The video transcoding cards are connected to the server motherboard via the PCIe Slot. For example, PCIe Slot 0 interacts with video transcoding card 0 through the PCIe link. The PCIe Slot connected to a single video transcoding card is fixed in the server.

[0063] For example, such as Figure 4 As shown, the video transcoding card of this application is connected to the server motherboard via a PCIe slot. Since the PCIe slot connected to a single video transcoding card is fixed in the server, and further, the PCIe Bus NumbEr and I2C Bus NumbEr corresponding to a single video transcoding card are also fixed, that is, there is a one-to-one correspondence between the PCIe Bus NumbEr and I2C Bus NumbEr of a single video transcoding card. The video transcoding card contains chips such as SOC (System-on-a-Chip), VR (Virtual Reality Chip), and CPLD (Programmable Logic Controller), with the main chip being the SOC. The P12V provided by the server motherboard's PSU (PC Power Supply Unit) is converted by the VR within the video transcoding card to provide the power required for the normal operation of the SOC. The server motherboard's BMC writes registers to the CPLD within the video transcoding card via the I2C link to control the on / off state of the VR, thereby controlling the power supplies of the SOC. Furthermore, the server motherboard BMC reads the registers of the CPLD inside the video transcoding card via the I2C link to obtain the power status of the video transcoding card. When the PWRGD (Power Normal) signal inside the video transcoding card is high, it indicates that all power supplies required for the normal operation of the video transcoding card SOC are normal. When PWRGD is low, it indicates that the video transcoding card SOC has lost power. The video transcoding card SOC interacts with the server motherboard CPU via the PCIe link to execute business scripts. The server CPU resets the video transcoding card via the PERST signal, thereby completing the re-establishment of the PCIe link. This invention avoids the risk of system crashes when a high-performance server is paired with a video transcoding card, and solves the problem of data loss caused by system crashes due to CPL errors at the video transcoding card when a high-performance server is running services with multiple video transcoding cards.

[0064] This application is applied to the CPU in a server. The CPU determines whether it receives data packets sent by the video transcoding card within a preset period. If no data packets are received within the preset period, the video transcoding card is identified as abnormal, and an error message is generated. Based on the error message, the I2C Bus NumbEr of the abnormal video transcoding card is determined. Then, the CPU stops PCIe read / write operations on the video transcoding card in the same slot as the abnormal one to prevent the problem from worsening and causing system crashes. The I2C Bus NumbEr is then sent to the local BMC (BasEboard). The Motherboard Management Controller (BMC) uses the I2C link and, based on the I2C bus number, sends a video transcoding card restart request to the programmable chip in the abnormal video transcoding card. The programmable chip then controls the power state of the virtual reality chip in the abnormal video transcoding card to restart it. After restarting, the virtual reality chip in the abnormal video transcoding card sets its normal power signal to a high level. The programmable chip generates power signal information and transmits this information to the Motherboard Management Controller via the I2C link. The CPU pulls the PERST signal of the abnormal video transcoding card slot low for a period of time. After receiving the processed low-level power signal information from the abnormal video transcoding card through the Motherboard Management Controller, it sets the low-level normal power signal to a high level and determines a new PCIe link with the system-on-a-chip in the video transcoding card. This new PCIe link is then used for PCIe data interaction and business script execution.

[0065] In this embodiment, it is determined whether a data packet sent by the video transcoding card is obtained within a preset period. If no data packet is obtained within the preset period, the video transcoding card is identified as an abnormal video transcoding card, and an error message is generated. Based on the error message, the PCIe bus number of the abnormal video transcoding card is determined, and then the PCIe link between the abnormal video transcoding card and the system-on-a-chip in the video transcoding card is disabled based on the PCIe bus number. Based on the error message, the I2C bus number of the abnormal video transcoding card is determined, and the I2C bus number is sent to the local baseboard management controller, so that the baseboard management controller sends a cold start processing request to the abnormal video transcoding card based on the I2C bus number. After the baseboard management controller obtains the processed power signal information sent by the abnormal video transcoding card, the connection between the baseboard management controller and the processed abnormal video transcoding card is re-established. This application determines whether data packets sent by the video transcoding card are received within a preset period. If not received, an error message is generated for cold start processing, and the connection with the processed abnormal video transcoding card is re-established. This can effectively avoid system crashes caused by CPU errors, resulting in loss of business data, and improve the stability of the video transcoding card in the server.

[0066] See Figure 5 As shown, this embodiment of the invention discloses a video transcoding card connection device, which may specifically include:

[0067] The judgment module 11 is used to determine whether data packets sent by the video transcoding card have been obtained within a preset period;

[0068] The error message generation module 12 is used to determine the video transcoding card as an abnormal video transcoding card and generate error messages if no data packet sent by the video transcoding card is obtained within a preset period.

[0069] The cold start module 13 is used to determine the I2C bus number of the abnormal video transcoding card based on the error information, and send the I2C bus number to the local baseboard management controller, so that the baseboard management controller can send a cold start processing request to the abnormal video transcoding card based on the I2C bus number.

[0070] The video transcoding card connection module 14 is used to re-establish the connection with the processed abnormal video transcoding card after obtaining the power signal information sent by the processed abnormal video transcoding card through the baseboard management controller.

[0071] In this embodiment, it is determined whether data packets sent by the video transcoding card are received within a preset period. If no data packets are received within the preset period, the video transcoding card is identified as an abnormal video transcoding card, and an error message is generated. Based on the error message, the I2C bus number of the abnormal video transcoding card is determined, and the I2C bus number is sent to the local baseboard management controller. The baseboard management controller then sends a cold start processing request to the abnormal video transcoding card based on the I2C bus number. After the baseboard management controller obtains the processed power signal information sent by the abnormal video transcoding card, it re-establishes the connection with the processed abnormal video transcoding card. This application determines whether data packets sent by the video transcoding card are received within a preset period. If no data packets are received, an error message is generated to perform cold start processing and re-establish the connection with the processed abnormal video transcoding card. This effectively avoids system crashes caused by CPU errors, resulting in data loss, and improves the stability of the video transcoding card operation in the server.

[0072] This application is applied to the CPU in a server. The CPU determines whether it receives data packets sent by the video transcoding card within a preset period. If no data packets are received within the preset period, the video transcoding card is identified as abnormal, and an error message is generated. Based on the error message, the I2C Bus NumbEr of the abnormal video transcoding card is determined. Then, the CPU stops PCIe read / write operations on the video transcoding card in the same slot as the abnormal one to prevent the problem from worsening and causing system crashes. The I2C Bus NumbEr is then sent to the local BMC (BasEboard). The Motherboard Management Controller (BMC) uses the I2C link and, based on the I2C bus number, sends a video transcoding card restart request to the programmable chip in the abnormal video transcoding card. The programmable chip then controls the power state of the virtual reality chip in the abnormal video transcoding card to restart it. After restarting, the virtual reality chip in the abnormal video transcoding card sets its normal power signal to a high level. The programmable chip generates power signal information and transmits this information to the Motherboard Management Controller via the I2C link. The CPU pulls the PERST signal of the abnormal video transcoding card slot low for a period of time. After receiving the processed low-level power signal information from the abnormal video transcoding card through the Motherboard Management Controller, it sets the low-level normal power signal to a high level and determines a new PCIe link with the system-on-a-chip in the video transcoding card. This new PCIe link is then used for PCIe data interaction and business script execution.
