PROXY QUEUE PAIR FOR OFFLOADING

摘要

A method for offloading includes a host channel adapter (HCA) receiving a first work request identifying a queue pair (QP), making a first determination that the QP is a proxy QP, and offloading the first work request to a proxy central processing unit (CPU) based on the first determination and based on the first work request satisfying a filter criterion. The HCA further receives a second work request identifying the QP, processes the second work request without offloading based on the QP being a proxy QP and based on the first work request failing to satisfy the filter criterion. The HCA redirects a first completion for the first work request and a second completion for the second work request to the proxy CPU based on the first determination. The proxy CPU processes the first completion and the second completion in order.

1. A method for offloading work requests of a queue pair (QP), comprising:
receiving, by the HCA, a first work request identifying the QP, wherein the QP is associated with an application executing on a host connected to the HCA; making a first determination that the QP is a proxy QP; offloading, by the HCA, the first work request to a proxy central processing unit (CPU) based on the first determination and based on the first work request satisfying a filter criterion; receiving, by the HCA, a second work request identifying the QP; processing, by the HCA, the second work request without offloading based on the QP being a proxy QP and based on the first work request failing to satisfy the filter criterion; redirecting a first completion for the first work request and a second completion for the second work request to the proxy CPU based on the first determination; and processing, by the proxy CPU, the first completion and the second completion in order.
