Patch series available in this git branch: https://xenbits.xen.org/git-http/people/aperard/xen-unstable.git br.build-system-xen-v1 Hi, I have work toward building Xen (the hypervisor) with Linux's build system, Kbuild. The main reason for that is to be able to have out-of-tree build. It's annoying when a build fail because of the pvshim. Other benefit is a much faster rebuild, and `make clean` doesn't take ages. The series start with a few cleanup patch, and an update to Kconfig that could be committed. The other patches that import Kbuild aren't ready. Quite a few functionality of the current build system are missing, like EFI build, Arm build, or build with clang. New features of Kconfig: - Can run shell commands! This could be use to generate the CFLAGS and cleanup the Kconfig files to not have to depends on some env var (like XEN_HAS_BUILD_ID). - Update to the graphical menuconfig, xconfig. It's now built with Qt4/Qt5. - Probably others that I forgot. Kbuild: I'm not sure how to move forward, easier change everything all at once with one big fat patch, or we could try to improve the current build system while taking inspiration from Kbuild. There are some nice make functions like if_changed which can also rebuild a target when the command line as changed (CFLAGS changed for e.g.). Also, with the `fixdep' program, files can depend on change to a single CONFIG_* instead of having to rebuild everything when .config change. With Kbuild, the list of CFLAGS is only done once, in the root Makefile, instead of every time a recursive make is done. Anyway, feel free to try that out. Some example (when in xen.git/xen dir): make V=2 -> show you why a target is rebuilt make V=1 -> show you the command line executed make O=builddir -> out-of-tree build (I haven't CCed anyone as I don't want to CC everyone from THE REST at this stage) Cheers, Anthony PERARD (23): xen: Fix strange byte in common/Kconfig xen: Makefile: Remove outdated comment xen: Update Kconfig to Linux v5.3
