The Error Detection And Correction "EDAC" subsystem updates have been merged for Linux 7.1 that deal with reporting of ECC memory errors and the like from various hardware drivers.
The amd64_edac driver used by modern AMD hardware for communicating of memory errors now supports Family 19h, Model 40h to 4fh CPUs. This ends up being for AMD Zen 3 Rembrandt APUs. It was an oversight that these Family 19h / Zen 3 models didn't have amd64_edac driver support and is just a three line patch for adding coverage to those missing models.
The patch from AMD confirms Rembrandt hardware having ECC memory support. Presumably some customer(s) are making use of Rembrandt + ECC for seeing this missing driver support added to the Linux kernel in 2026. AMD Rembrandt is for the Ryzen 6000 series mobile processors.
Meanwhile over on the Intel EDAC side, the i10nm driver has added Granite Rapids error information decoder support as an alternative to Granite Rapids' firmware-based decoder.
Those are the main highlights from the [1]EDAC pull now merged for the Linux 7.1 kernel.
