Emulating CXL with QEMU
Abstract
In order to develop open source CXL ecosystem software it has proven useful to emulate CXL features within the QEMU project. In this talk, I will introduce the current major CXL features that QEMU can emulate and walk you through how to set up a Linux + QEMU CXL environment that will enable testing and developing new CXL features. In addition, I will highlight some of the limitations of QEMU CXL emulation.
Learning Objectives
Emulate CXL hardware leveraging open-source tools.
Understand some of the latest CXL features that are being currently developed.
Grasp the importance of open ecosystems for emerging technologies.
