Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the present disclosure. One skilled in the relevant art will recognize, however, that the aspects of the disclosure may be practiced without one or more of the specific details, or with other methods, components, devices, steps, etc. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.

As shown in fig. 1, the embodiment of the present disclosure provides a method for implementing GMAC port forced communication based on a domestic Feiteng platform, which specifically includes steps S101 to S103:

in step S101, when the GMAC driver loads the configuration PHY, an ACPI node corresponding to the network interface is acquired, and whether a fixed-link node exists is detected.

Among them, GMAC (Gigabit Media Access Controller) refers to an ethernet physical layer interface, and in an operating system, an ACPI node is a hierarchical structure for representing and organizing hardware devices and functions thereof, and by analyzing the ACPI node, information and configuration of the devices can be obtained. The fixed-link node is a node in the ACPI description and is used to represent a network card with a fixed link characteristic, specifically to indicate that the network card does not need to determine link modes and parameters through auto-negotiation.

In step S102, if the fixed-link node exists under the ACPI node, MII bus registration of the PHY is suspended.

Specifically, if a fixed-link node exists in the ACPI description of the network card, this indicates that the network card has a fixed link characteristic. At this time, MII (Media Independent Interface) bus registration of ordinary PHY (PHYsical Layer) is not required. Among these, PHY is a converter between a network interface controller and a physical medium, and MII is an interface standard for connecting PHY and MAC (Media Access Control).

In step S103, when initializing the PHY, it is detected whether the fixed-link node exists, if so, parameters related to forcibly setting a fixed link mode under ACPI description are obtained, registration of the fixed_phy is performed according to the obtained parameters, and the registered fixed_phy is associated with the corresponding GMAC.

Specifically, at the time of PHY initialization, it is also determined whether or not there is a fixed-link node. Relevant forced link parameters, such as half full duplex mode, rate, etc., are obtained from the ACPI description, if any. Then, the respective fixed_phy is correctly registered according to the acquired parameters and associated with the corresponding GMAC (Gigabit Media Access Controller). fixed_phy refers to a fixed PHY, which is a hard-coded PHY instance in a driver, and may represent a PHY device with fixed link characteristics. In half duplex mode, it means that both parties can alternately transmit and receive data, but cannot simultaneously transmit and receive. The rate refers to the transmission rate of the network interface.

Based on the method, the uboot firmware can be selected as development without fixation, and the UEFI firmware can be selected so as to have selection diversity to be suitable for different scenes; the method is matched with the switch which can be managed by the method, and in the debugging stage, the initialization configuration of the switch can be realized by upgrading the bin file of the switch without changing the uefi firmware every time; further, the developer can inform the system of the method through the UEFI firmware ACPI description according to the requirement, so that the system correctly loads the corresponding PHY driver according to the description to realize forced link connection.

Based on the same, in one embodiment, an electronic device is provided, comprising:

the processor is used for acquiring ACPI nodes corresponding to the network interfaces and detecting whether fixed-link nodes exist or not when the GMAC drives load the configuration PHY;

if the fixed-link node exists under the ACPI node, suspending MII bus registration of the PHY;

and when the PHY is initialized, detecting whether the fixed-link node exists, if so, acquiring parameters related to forced setting of a fixed link mode under ACPI description, registering the fixed_PHY according to the acquired parameters, and associating the registered fixed_PHY with the corresponding GMAC.
