Method and apparatus for PCIE interface compatible with use of yinshan card, and storage medium

An apparatus for a PCIe interface compatible with use of a Yinshan card, comprising:

• a RISER card, wherein the RISER card comprises a specific PCIe slot, and the specific PCIe slot is configured to generate a board type signal in response to a card being inserted into the specific PCIe slot, the specific PCIe slot is a PCIe slot in the RISER card;
• a RISER card slot, wherein the RISER card is configured to insert into the RISER card slot;
• and
• a main processor, configured to read the board type signal, determine whether the inserted card is a Yinshan card or a standard PCIe interface card based on the board type signal, display the type of the card on a BIOS interface based on a determination result, and receive, by a BIOS, a Yinshan card working mode selected by a user in response to the inserted card being the Yinshan card, and control, by a GPIO port of the main processor, a working mode selection signal of the RISER card slot based on the Yinshan card working mode, wherein
• the RISER card is configured to allocate a corresponding PCIe resource to the Yinshan card based on the working mode selection signal;
• the RISER card is further configured to control a PCIe switch within the RISER card to select and access a corresponding signal based on a level state of the working mode selection signal, and allocate the corresponding PCIe resource to the Yinshan card based on the accessed signal.

A non-transitory computer readable storage medium, storing computer program instructions, wherein the computer program instructions, when executed by a processor, implement a method for a PCIe interface compatible with use of a Yinshan card, wherein the method comprises:

• in response to a card being inserted into a specific PCIe slot in a RISER card, reading, by a main processor, a board type signal through the specific PCIe slot, determining whether the inserted card is a Yinshan card or a standard PCIe interface card based on the board type signal, and displaying the type of the card on a BIOS interface based on a determination result;
• in response to the inserted card being the Yinshan card, receiving, by a BIOS, a Yinshan card working mode selected by a user, and controlling, by a GPIO port of the main processor, a working mode selection signal of a RISER card slot based on the Yinshan card working mode;
• and
• allocating a corresponding PCIe resource to the Yinshan card through the RISER card based on the working mode selection signal;
• wherein allocating the corresponding PCIe resource to the Yinshan card through the RISER card based on the working mode selection signal comprises:
• controlling a PCIe switch within the RISER card to select and access a corresponding signal based on a level state of the working mode selection signal, and allocating the corresponding PCIe resource to the Yinshan card based on the accessed signal.
