CXL-DMSim is a full-system CXL disaggregated memory simulator based on gem5. This repository extends Linux 5.4.49 by adding a custom driver for a CXL device and modifying parts of the NUMA code to enable the CXL device to be recognized as a CPU-less NUMA node. The corresponding patch can be found in the releases.
Note:
- To enable the CXL driver, configure
CONFIG_CXL_MEM=yorCONFIG_CXL_MEM=m. - To enable NUMA, ensure all NUMA-related options are configured.
We provide a cxl.config file as a configuration reference.
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use make htmldocs or
make pdfdocs. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
