Description

Required prerequisites

  • I have searched the Issue Tracker that this hasn't already been reported. (comment there if it has.)

Motivation

Currently, Qualcomm has released the Hexagon Kernel Library (https://softwarecenter.qualcomm.com/catalog/item/Hexagon_KL), which provides interfaces for HMX instructions. There are currently many edge devices powered by Qualcomm chips, and specialized attention mechanisms like sparse attention are also well-suited for mobile devices. We can leverage tilelang's capabilities to achieve CodeGen for the Hexagon backend targeting custom attention implementations and other operators.
