tools/rtla: Use tools/build makefiles to build rtlaUse tools/build/ makefiles to build rtla, inheriting the benefits ofit. For example, having a proper way to handle dependencies.rtla is built using perf infra-structure when building inside thekernel tree.At this point, rtla diverges from perf in two points: Documentationand tarball generation/build.At the documentation level, rtla is one step ahead, placing thedocumentation at Documentation/tools/rtla/, using the same buildtools as kernel documentation. The idea is to move perfdocumentation to the same scheme and then share the same makefiles.rtla has a tarball target that the (old) RHEL8 uses. The tarball waskept using a simple standalone makefile for compatibility. Thestandalone makefile shares most of the code, e.g., flags, withregular buildings.The tarball method was set as deprecated. If necessary, we can makea rtla tarball like perf, which includes the entire tools/build.But this would also require changes in the user side (the directorystructure changes, and probably the deps to build the package).Inspired on perf and objtool.Link: https://lkml.kernel.org/r/57563abf2715d22515c0c54a87cff3849eca5d52.1710519524.git.bristot@kernel.orgCc: Arnaldo Carvalho de Melo Cc: Josh Poimboeuf Cc: John Kacur Cc: Namhyung Kim Cc: Jiri Olsa Suggested-by: Linus Torvalds Signed-off-by: Daniel Bristot de Oliveira List of files: /linux-6.15/tools/tracing/rtla/Build
