[OS-BUILD PATCHv4] redhat/configs: enable kernel .config support
by Ricardo Robaina (via Email Bridge) 28 Mar '25

28 Mar '25

From: Ricardo Robaina <rrobaina(a)redhat.com> redhat/configs: enable kernel .config support Issue: https://issues.redhat.com/browse/RHEL-82530 Upstream Status: RHEL-Only Several kernel-tests check the configuration options used to build the currently running kernel to be able to run tests accordingly [1]. However, depending on the deployment method some .config sources might not be available. For instance, in image mode, the /boot directory does not exist. This patch enables CONFIG_IKCONFIG and CONFIG_IKCONFIG_PROC to expose kernel .config data via /proc/config.gz, enabling an extra source of .config, thus ensuring redundancy of this information to make kernel tests more robust and allowing it to support current and future kernel variants and environments.

[OS-BUILD PATCHv6 0/2] redhat/kernel.spec: use target versions of tools for debugedit and gdb-add-index
by Jan Stancek (via Email Bridge) 28 Mar '25

28 Mar '25

From: Jan Stancek on gitlab.com Merge Request: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/3714 debugedit-5.1-5.fc42 adds support to override tools with target versions: find-debuginfo relies on a couple of binutils tools (readelf, objcopy and nm) that might not have been build with cross-arch support. Make it possible to configure with specific (target) versions and to override the specific binaries by setting READELF, OBJCOPY or NM environment variables. which means we can now have find-debuginfo working also for cross builds when we give it correct version of nm, readelf and objcopy.
