Description Frank Ch. Eigler 2025-03-07 17:38:32 UTC 
At various points in the past, the kernel rpm has been built with debuginfod client support in perf, which allows things like dwarf-based unwinding, source code fetching & annotation to work transparently.  But in recent kernels, this appears to have disappeared again.

Please consider adding a

BuildRequires: elfutils-debuginfod-client-devel

to the kernel.spec, so the perf Makefile feature auto-detection activates this functionality.

Reproducible: Always
Comment 1 Frank Ch. Eigler 2025-10-08 22:03:43 UTC 
Could we please have some feedback about what is blocking adding this BuildRequires: to kernel.spec?  Over in ARK land, we did what seemed like due diligence, updating the buildroots.  What else need we do?

The current issue is that the MR was not rebased after os-build was rebased (this happens every .0 release).   But if I had to guess before that, the CKI failed because of the build root issue, and no one ever asked to have it re-run after the build root containers were changed to include it.  With a failed CKI, there was likely no one willing to take time to review it.
