Title:
METHOD, APPARATUS, AND DEVICE FOR DEVICE ENUMERATION FOR PCIE INTERFACE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/166170
Kind Code:
A1
Abstract:
A method, apparatus, computer device for device enumeration for a PCIe interface, and a computer-readable storage medium. The method comprises: while a PCIe endpoint is in a kernel stage of booting and startup, detecting a physical link state of a PCIe interface; insofar as the physical link state is no connection established, detecting for a preset enumeration signal via the PCIe interface, keeping a device enumeration resource from being released, and continuing to complete the booting and startup of the PCIe endpoint; and when the preset enumeration signal transmitted by a PCIe root complex is detected, utilizing the device enumeration resource to complete the enumeration of the PCIe interface with the PCIe root complex. The present invention avoids a case in which enumeration can no longer be completed once the enumeration during the power-on and booting of a PCIe device is missed; moreover, by detecting the preset enumeration signal, the PCIe root complex is allowed to complete simultaneous enumerations at any time, thus avoiding strong reliance on different host architectures, and reducing the requirement on timing control with respect to the PCIe root complex.
