[Bug 2077861] Re: [SRU]Intel Arrow Lake IBECC feature backport request for ubuntu 22.04.5 and 24.04.1 server

This bug is awaiting verification that the linux/6.8.0-50.51 kernel in
-proposed solves the problem. Please test the kernel and update this bug
with the results. If the problem is solved, change the tag
'verification-needed-noble-linux' to 'verification-done-noble-linux'. If
the problem still exists, change the tag 'verification-needed-noble-
linux' to 'verification-failed-noble-linux'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.


See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
[SRU]Intel Arrow Lake IBECC feature backport request for ubuntu
22.04.5 and 24.04.1 server

Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Noble:
Fix Committed
Status in linux source package in Oracular:
Fix Released

Bug description:
[Impact]
Add Arrow Lake-U/H SoC compute die IDs for EDAC support.

However, the OS scope in LENOVO are ubuntu 22.04 and 24.04 server
version, which are using Linux kernel 6.8, due to this reason, can
this feature be backport to these two version, thanks!

[Test Plan]


[Fix]
According to https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=88150cd9501b9498e377cc4440325267c6921f90, Intel Arrow Lake IBECC(In-Band ECC)) feature is already added in upstream.

EDAC/igen6: Add Intel Arrow Lake-U/H SoCs support
Arrow Lake-U/H SoCs share same IBECC registers with Meteor Lake-P
SoCs. Add Arrow Lake-U/H SoC compute die IDs for EDAC support.
