More CXL Work On The Way For Linux 6.2 (Compute Express Link)

Written by Michael Larabel in Hardware on 4 December 2022 at 06:21 AM EST. 3 Comments
Thanks to the ongoing work led by Intel's Linux engineers, the upcoming Linux 6.2 kernel will feature more feature work around enabling Compute Express Link (CXL) functionality.

A lot of "for-6.2" material has been queuing in recent days within the CXL subsystem's Git codebase. Linux 6.1 is expected to be released one week from today and in turn will mark the start of the Linux 6.2 merge window where this CXL work and other feature additions will be submitted.

Among the CXL work that has been happening for Linux 6.2 includes support for CXL XOR Interleave Math (CXIMS), AER (Advanced Error Reporting) support for error handling, initial work around Persistent Memory Data-at-rest Security, and other improvements to this CXL software support that will play an important role with next-generation servers. Long story short, things continue moving along on the CXL enablement front for Linux and the work continues to be led by Intel's software engineers.

Those interested can track the latest CXL software development progress for the Linux kernel via cxl.git. Following the Linux 6.2 merge window this month, the Linux 6.2 stable release should be out in February.
