Abstract
Examples relate to apparatuses, devices, methods and computer programs for a Root Complex (RC) and/or for an Endpoint (EP) of a PCIe (Peripheral Component Interconnect express) system, to a PCIe system and to a gateway device comprising a PCIe system. An apparatus configured for a RC of a PCIe system comprises a memory and one or more processors, which are configured to generate a PCIe VDM (Vendor Defined Message) message for an EP of the PCIe system.
Claims12
An apparatus configured for a Root Complex (RC) of a PCIe (Peripheral Component Interconnect express) system, comprising:
- a memory;
- and
- one or more processors configured to:
- generate a PCIe VDM (Vendor Defined Message) message for an EP (Endpoint) of the PCIe system, wherein the PCIe VDM message comprises at least one of:
- an interrupt trigger for the EP of the PCIe system, information on a reset status at the RC, information on a status of at least one data path, or information on a buffer status.
An apparatus configured for an Endpoint (EP) of a PCIe (Peripheral Component Interconnect express) system, comprising:
- a memory;
- and
- one or more processors configured to:
- process a PCIe (Peripheral Component Interconnect express) VDM (Vendor Defined Message) message from a RC (Root Complex) of the PCIe system, wherein the PCIe VDM message comprises at least one of:
- an interrupt trigger for the EP of the PCIe system, information on a reset status, information on a status of at least one data path, or information on a buffer status.
