Hello Bruce, This upgrade broke build of external kernel modules for powerpc. Yocto test devtool.DevtoolTest.test_devtool_kernelmodule is failing. We have prepared a patch for upstream kernel. https://lore.kernel.org/all/20250919121417.1601020-1-alexander.sverdlin@siemens.com/ But I guess it will take lot of time to get picked there, then backported to 6.16, tagged and finally this tag picked by yocto. Is there a process to pick this patch already now to keep the pipeline green?

(damn outlook and html prevents me to properly quote this below, sorry) The commit description is not ideal and we struggle to fully understand why it was not failing before. Maybe it was not being built and new config changes trigger it now? This also seems to be a missed line in 214c0eea43b2ea66bcd6467ea57e47ce8874191b from last year. As it says "This commit prepares for supporting the building of external modules..." maybe some new commits built on this feature and this broke at that time because not all places were properly prepared. I’ll probably wait until it gets merged to kernel master before submitting to linux-yocto.

Your > fix is simpler than the old one we had, so that's progress :) I believe, the removed patches were rather backports from the upstream kernel solving the dependency issues for in-tree modules. The current issue looks a bit different and is, I believe, an issue for external modules only. But the above unfortunately makes it harder to explain why the external modules were buildable before ;-) -- Alexander Sverdlin Siemens AG www.siemens.com

This ensures that out-of-line register saves/restores work when CONFIG_CC_OPTIMIZE_FOR_SIZE is enabled. What it didn't do was ensure that it was built when modules_prepare was run and hence out of tree powerpc kernel modules can't properly link. The fix is to add crtsavres.o to the archprepare rule in the arch/powerpc/Makefile Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com> ---------- Cheers, Bruce > > But the above unfortunately makes it harder to explain why the external > modules > were buildable before ;-) > > -- > Alexander Sverdlin > Siemens AG > www.siemens.com >

Thanks for the follow up. I merged the latest -stable last night, so there will be more bumps to 6.16 today.
