Host embedded controller interface bridge

摘要

A system, method, and computer readable medium are disclosed. In one embodiment the system includes a remote computer system. The remote computer system has a remote host embedded controller interface (HECI) driver and a HECI simulator. The HECI simulator intercepts commands directed to the HECI driver from software running on the remote computer system and routes the commands as HECI messages to a local computer system also included in the system. The local computer system includes a HECI bridge that is capable of receiving the HECI messages sent from the remote computer system and then can pass the received HECI messages to a local HECI driver to be operated upon.

1. A local computer system, comprising:
a host embedded controller interface (HECI) message routing table to list a set of response target addresses within the local computer system and a set of response target addresses within a remote computer system; a targeted technology comprising a hardware component or a firmware component of the local computer system; and an HECI bridge, the bridge to:
receive HECI messages sent from the remote computer system, the HECI messages routed from commands directed to an HECI driver of the remote computer system from software running on the remote computer system, and wherein the HECI messages include an identifier indicative of the targeted technology;pass the received HECI messages to the targeted technology of the local computer system to be executed;receive response HECI messages to the received HECI messages from the targeted technology in response to passing of the received HECI messages to the targeted technology;look up the target address of each response HECI message using the HECI message routing table;route each response HECI message targeting an address in the remote computer system to the remote computer system, the response HECI messages to be passed as responses to the software running on the remote computer system;route each response HECI message targeting an address in the local computer system to the local computer system; andrestrict the availability of one or more interfaces within the local computer system to the remote computer system.
