Technologies for flexible protocol acceleration

A method for I/O protocol acceleration, the method comprising:

• receiving, by a smart endpoint of a computing device, an I/O transaction originating from a root port of the computing device, wherein the smart endpoint is coupled to the root port, and wherein the smart endpoint is further coupled to an offload complex of the computing device;
• parsing, by the smart endpoint, the I/O transaction based on an I/O protocol in response to receiving the I/O transaction;
• identifying, by the smart endpoint, an I/O command in response to parsing the I/O transaction;
• accelerating, by the smart endpoint, the I/O command;
• and
• providing, by the smart endpoint, a smart context to the offload complex in response to accelerating the I/O command.

One or more computer-readable storage media comprising a plurality of instructions stored thereon that, in response to being executed, cause a computing device to:

• receive, by a smart endpoint of the computing device, an I/O transaction originating from a root port of the computing device, wherein the smart endpoint is coupled to the root port, and wherein the smart endpoint is further coupled to an offload complex of the computing device;
• parse, by the smart endpoint, the I/O transaction based on an I/O protocol in response to receiving the I/O transaction;
• identify, by the smart endpoint, an I/O command in response to parsing the I/O transaction;
• accelerate, by the smart endpoint, the I/O command;
• and
• provide, by the smart endpoint, a smart context to the offload complex in response to accelerating the I/O command.
