Hi all,
This set adds a new module to manage error records on persistent
storage.
Patch 1 moves a function from AMD64 EDAC to the AMD Address Translation
Library. This is needed for patch 2.
Patch 2 adds the new module. This is a near total rewrite based on patch
2 from the following set:
https://lore.kernel.org/r/20231129075034.2159223-1-murali...
I included questions in code comments where I think more attention is
needed.
I'd like to add Murali and Naveen as Co-developers, since this is based
on their work. Also, I kept Naveen as a maintainer in case he's still
interested.
Regarding the old set:
* Patch 1 exports a new function from the ERST driver. This is not
necessary.
* Patch 3 adds a new sysfs interface. This needs more work.
* Patch 4 old set adds documentation. This needs updating.
I did some basic testing on a 2P server system without ERST support.
Mostly I tried to check out the memory layout of the structures. And I
did some memory error injections to check out the record updating flow.
I did some fixups after testing, so I apologize if I missed anything.
Thanks,
Yazen
