Abstract
A method for sending readiness notification messages to a root complex in a peripheral component interconnect express (PCIe) subsystem. The method includes receiving a device-ready-status (DRS) message in a downstream port that is coupled to an upstream port in a PCIe component. The method further includes setting a bit in the downstream port indicating that the DRS message has been received.
Claims20
A computer-implemented method for sending readiness notification messages to a root complex, the method comprising:
- receiving a device-ready-status (DRS) message in a downstream port that is coupled to an upstream port in a peripheral component interconnect express (PCIe) component;
- and
- setting a bit in the downstream port indicating that the DRS message has been received.
A peripheral component interconnect express (PCIe) subsystem comprising downstream port configured to:
- receive a device-ready-status (DRS) message from an upstream port in a component that is coupled to the downstream port;
- and
- set a bit in the downstream port indicating that the DRS message has been received.
A computing device comprising:
- a peripheral component interconnect express (PCIe) subsystem comprising:
- a downstream port configured to:
- receive a device-ready-status (DRS) message from an upstream port in a component that is coupled to the downstream port;
- and
- set a bit in the downstream port indicating that the DRS message has been received.
