Description John W. Linville 2023-07-12 13:12:39 UTC
+++ This bug was initially created as a clone of Bug #2171891 +++

Update the CXL support in the RHEL9 kernel to same functionality as in upstream 6.4.

Comment 8 John W. Linville 2023-07-25 19:29:27 UTC
I'm experiencing a lot of difficulties in getting a clean(ish) backport even from upstream 6.3. Backporting from 6.4 may be neither practical nor desirable.

Comment 9 John W. Linville 2023-07-28 19:19:24 UTC
Closing this to remove the item from consideration. Any further CXL changes to RHEL9.x need individual justification and consideration on a case by case basis.
