From: Kienan Stewart Date: Mon, 27 Jan 2025 16:48:32 +0000 (+0000) Subject: Fix: powerpc builds with linux v6.13 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=9e9226618052111d31eaffd2fbb80af8e890a234;p=lttng-modules.git Fix: powerpc builds with linux v6.13 The crtsavres.o object for powerpc is missing the $(objtree) prefix. This can be worked-around by setting MO=$KERNELDIR and building in the kernel tree as before this version. See upstream commit: commit 214c0eea43b2ea66bcd6467ea57e47ce8874191b Author: Masahiro Yamada Date: Sun Nov 10 10:34:30 2024 +0900 kbuild: add $(objtree)/ prefix to some in-kernel build artifacts $(objtree) refers to the top of the output directory of kernel builds. This commit adds the explicit $(objtree)/ prefix to build artifacts needed for building external modules. This change has no immediate impact, as the top-level Makefile currently defines: objtree := . This commit prepares for supporting the building of external modules in a different directory.
