Public bug reported: [Impact]
* pahole used to segfault on 32-bit platforms, which has now been fixed * pahole used to be too old in focal, which is now being SRUed * renable DEBUG_INFO_BTF in all the kernels/arches that had it disabled, as otherwise one cannot compile/use advanced BTF features on newer kernels. [Test Plan] * Check the built kernel's config that it has CONFIG_DEBUG_INFO_BTF=y * Check build log that it contains ``` BTF .btf.vmlinux.bin.o ``` [Where problems could occur] * In the future, kernel may require even newer version of pahole from dwarves, making the builds fail to build again, as building BTF debug information will now be required. Until either BTF is disabled again or pahole is upgraded again. [Other Info] * Latest pahole is available from focal-proposed, hirsute-proposed, impish release, builders-extra PPA ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1945632 Title: Re-enable DEBUG_INFO_BTF where it was dissabled Status in linux package in Ubuntu: New Bug description: [Impact] * pahole used to segfault on 32-bit platforms, which has now been fixed * pahole used to be too old in focal, which is now being SRUed * renable DEBUG_INFO_BTF in all the kernels/arches that had it disabled, as otherwise one cannot compile/use advanced BTF features on newer kernels.
