Hello, This is just a headsup that I've been working on the EDAC driver based on the ARMv8 RAS extensions. AFAIK, there were 3 attempts [1][2][3] on getting this merged in different forms.
I've collected the feedback on those submissions and came up with the idea of a single "armv8_ras_edac" driver which will work for both Devicetree and ACPI systems. The core part of the driver will be platform agnostic, such that it will get the information for RAS error nodes from either ACPI or DT whichever available. As per the suggestion by James, I've taken the "ACPI platform design doc for ARMv8 RAS Extensions v1.1" [4] as the reference and working on the devicetree design. Apart from ACPI specific properties such as headers etc,.. most of the content will be the same in devicetree. But my submission will be only focused on DT and not ACPI. This is due to my limitation on getting an ACPI supported RAS platform for development/testing. If anyone is willing to collaborate on this part, please let me know. I will submit the RFC series once it available!
