The embodiment of the invention provides a modularized PCIE (peripheral component Interface express) equipment software simulation method, which is characterized in that a DXE _ DRIVER (DRIVER component) which accords with a Unified Extensible Firmware Interface (UEFI) specification is added, a protocol (protocol) related to a PCIE is installed for the DXE _ DRIVER, and related parameters set by the DRIVER component are added, so that the UEFI can be simulated as a Controller object (a special Image object) generated in a memory by the PCIE equipment. The PCIE equipment of the entity does not need to be matched, and the corresponding PCIE equipment is simulated only through options, so that the efficiency of firmware development is improved, and the successful implementation of customer customization and project development is ensured.

And creating a driving assembly based on the unified extensible firmware interface specification, and taking the PCIE information structure body as a picture object of the driving assembly.

In some embodiments, the taking the PCIE information structure as the picture object of the driving component includes: creating a corresponding controller object for each PCIE device for controlling the PCIE device. And creating a standard DXE _ DRIVER, taking a PCIE information structure existing in the code as an Image object operated by a drive component, and carrying out initialization configuration on the parameters of the Image object.

And installing PCIE (peripheral component interface express) related protocols on handles which point to the picture objects by the driving components. Each DXE _ DRIVER has a HANDLE to the Image object, which is of the EFI _ HANDLE type, to which PCIE related protocol is installed using standard commands of UEFI.

In some embodiments, the installing the PCIE-related protocol on the handle to the picture object by the drive component includes: a first protocol for device access and a second protocol for obtaining a device path are installed on the handle. For example: the method comprises the steps of PciIoProtocol for equipment access and DevicePathProtocol for obtaining equipment paths, wherein the protocols are installed on a handle, and a PCIE Image which can be loaded in an internal memory is simulated.

PCIE related protocols exist in a HANDLE EFI _ HANDLE of the Image file, and when UEFI identifies and displays all PCIE equipment, the Image file can be positioned to an Image object through the HANDLE, and identification and subsequent related operations are carried out on the Image object. Parameters can be customized in the former PCIE equipment parameter configuration, so that the development, adaptation and other work can be more conveniently carried out.

After the UEFI scans the bus, a Controller object is established for each PCIE device to control the device and point to it through EFI _ HANDLE, and the UEFI installs a related protocol for the device to implement functions of identifying and accessing the device. And finally, a. EFI file is generated through a DXE _ DRIVER module added by UEFI specification, when UEFI loads the file into a memory, an Image object is also established for the file, the Image object is also an EFI _ portable object, and if a related protocol is installed for the file, UEFI also recognizes the file as a PCIE device and recognizes and accesses the PCIE device.
