The Current State Of CXL Support On Linux


Immediately prior to the Linux 6.11-rc1 kernel being released yesterday, a set of Compute Express Link (CXL) patches were merged for the Linux kernel

CXL enablement remains an ongoing affair given the multiple versions and different device types / sub-protocols. Documentation updates to the Linux kernel aren't usually too notable but this CXL pull request does bring an important one: a concise overview of the current Linux support for different CXL features. The full list of CXL changes merged for Linux 6.11 can be found via this Git commit.
