The Linux 7.3 kernel now includes late EDAC changes, enhancing support for AMD and Intel systems. Engineers should note improved address translation and orphaned drivers, affecting system stability and log management.
In a notable update to the Linux 7.3 kernel, the Error Detection and Correction (EDAC) subsystem changes have been merged after initially being overlooked during the merge window. This integration, as detailed by Phoronix, is significant for engineers working with AMD and Intel systems, as it introduces several improvements and clean-ups that enhance system stability and functionality.
For Intel, the update includes support for the Starfire SoC in the iGEN6 EDAC driver. Starfire, a derivative of Panther Lake, is designed for use in extreme conditions, such as space environments. The iGEN6 and iE31200 Intel client EDAC drivers have also unified parts of their address translation logic, resulting in a more streamlined codebase.
On the AMD side, a practical enhancement involves the Address Translation Library (ATL). Previously, it loaded on all AMD Zen systems, causing unnecessary log spam on non-ECC platforms due to failed load attempts. Now, the ATL only loads on systems with ECC memory, reducing kernel log noise and improving overall system behavior.
However, not all changes are about new additions. The update sees the orphaning of the ThunderX and MPC85XX EDAC drivers. The ThunderX driver, for Cavium/Marvell ARM SoCs, and the MPC85XX driver, for Freescale/NXP PowerPC memory controllers, are now without maintainers. This likely signals their removal in future kernel versions unless new maintainers step forward.
As LWN reports, these changes come amidst a surge of activity in the Linux 7.3 merge window, which saw 15,267 non-merge changesets integrated, marking one of the busiest periods in the kernel's history. For engineers, this means a Linux 7.3 update that not only fixes previous oversights but also potentially affects ongoing support for certain hardware. It's a solid improvement for those relying on AMD and Intel systems, but it also serves as a reminder of the need for continuous hardware support management in the open-source community.
