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.
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.

Main memory dominates data center server cost, and hence, data center operators are exploring alternative technologies such as CXL-attached memory to improve cost without jeopardizing performance.
CXL offers unprecedented opportunities to design and build much larger application and compute arrangements than were available even a few years ago.
