Ahead of Intel Diamond Rapids server processors launching in 2027, the Linux kernel continues getting into shape for these next-gen Xeon processors. The latest enablement work taking place for Diamond Rapids is readying the Error Detection And Correction (EDAC) driver support for propagating memory errors\/correction information under Linux.<\/p>\n

With Diamond Rapids’ Retry Read Error Log “RRL” it now operates at a sub memory channel granularity and thus the Intel EDAC driver code had to be restructured. Over the course of several patches queued into the “edac-for-next” Git branch that has now taken place. Following the prep work is this patch going ahead in enabling RRL support for intel Xeon Diamond Rapids.
\n<\/p>\n

“Compared to previous generations, Diamond Rapids RRL (Retry Read error Log) operates at DDR sub-channel granularity and adds an extra register per set. It also increases the CORRERRCNT register width from 4 to 8 bytes while reducing the number of registers from 8 to 4.<\/p>\n

Add the Diamond Rapids RRL register configuration table and enable support.”<\/p>\n

With that support in edac-for-next, it’s in turn expected to be merged later this month for the Linux 7.2 kernel merge window.<\/p>\n

\"Intel<\/p>\n

Separately, also queued in the past few days to edac-for-next is adding Nova Lake H SoC support to the IGEN6 EDAC driver. Nova Lake H’s memory controller registers and in-band ECC registers are similar to Panther Lake H but with some minor differences now accommodated for in that queued code for allowing EDAC support on that next-gen SoC.
