Abstract

The invention discloses a PCIe RC and EP mode switching method and device, equipment and a medium. The PCIe RC and EP mode switching method comprises the following steps: reading a root environment variable according to an equipment starting instruction; a PCIe mode is judged according to the root environment variable, and the PCIe mode comprises an RC mode or an EP mode; opening a corresponding device tree according to the RC mode or the EP mode; an indication parameter is obtained based on the root environment variable, in the kernel loading stage, a target drive is loaded according to the indication parameter, and the target drive comprises an RC mode drive or an EP mode drive; and completing PCIe mode setting of the equipment according to the equipment tree and the RC mode drive corresponding to the RC mode or the equipment tree and the EP mode drive corresponding to the EP mode. According to the PCIe RC and EP mode switching method, the production cost of the communication module can be effectively reduced.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular, to a PCIe RC and EP mode switching method, apparatus, device and medium. Background technique [0002] Currently embedded Linux-based communication modules (including but not limited to 5G, 4G and other wireless communication modules) support PCIe (Peripheral Component Interconnect Express, high-speed serial computer expansion bus standard) high-speed interface RC (RootComplex, root complex) mode (master mode) and EP (EndpointDevice, endpoint device) mode (slave mode). The RC mode is used for external expansion devices (PHY (physical, port physical layer) / LAN (Local Area Network, local area network) / Wi-Fi (wireless network communication technology)), and the EP mode is used to connect to the host computer as a slave device. [0003] Existing application scenarios such as 5G communication module high-speed network use a large number of RC mode or EP mode...
