Patch series available in this git branch: https://xenbits.xen.org/git-http/people/aperard/xen-unstable.git br.build-system-xen-v5 v5: - few changes detailed in patch notes. - 1 new patch v4: - some patch already applied. - Have added patches from "xen/arm: Configure early printk via Kconfig" series. - Some new patch to add documentation or fix issues, and patch to improve compat header generation. Other changes are detailed in patches. v3: - new patches that do some cleanup or fix issues - have rework most patches, to have better commit message or change the coding style, or fix issues that I've seen. There were some cases where CFLAGS were missing. See patch notes for details - introduce if_changed*. That plenty of new patches on top of what we had in v2. (those changes ignore CONFIG_LTO=y, I'll see about fixing that later) (There is more to come in order to use fixdep from Linux, but that's not ready) 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, and better dependencies to figure out what needs to be rebuild. So, we are not there yet, but the series already contain quite a few improvement and cleanup. More patches are going to be added to the series. Cheers, Anthony PERARD (16): build,xsm: Fix multiple call xen/build: include include/config/auto.conf in main Makefile xen/build: use new $(c_flags) and $(a_flags) instead of $(CFLAGS) xen/build: have the root Makefile generates the CFLAGS build: Introduce documentation for xen Makefiles xen/build: introduce if_changed and if_changed_rule xen/build: Start using if_changed build: Introduce $(cpp_flags) xen/build: use if_changed on built_in.o xen/build: Use if_changed_rules with %.o:%.c targets xen/build: factorise generation of the linker scripts xen/build: Use if_changed for prelink*.o xen,symbols: rework file symbols selection build: use if_changed to build mm/*/guest_%.o build,include: rework compat-build-source.py build,include: rework compat-build-header.py .gitignore | 1 + docs/misc/xen-makefiles/makefiles.rst | 185 ++++++++++++++++++++ xen/Makefile | 212 ++++++++++++++++++++--- xen/Rules.mk | 235 ++++++++++++++++---------- xen/arch/arm/Makefile | 22 +-- xen/arch/arm/Rules.mk | 23 --- xen/arch/arm/{Rules.mk => arch.mk} | 5 - xen/arch/arm/efi/Makefile | 2 +- xen/arch/x86/Makefile | 41 ++--- xen/arch/x86/Rules.mk | 91 +--------- xen/arch/x86/{Rules.mk => arch.mk} | 17 +- xen/arch/x86/efi/Makefile | 9 +- xen/arch/x86/mm/Makefile | 14 +- xen/arch/x86/mm/hap/Makefile | 15 +- xen/arch/x86/mm/shadow/Makefile | 14 +- xen/common/libelf/Makefile | 14 +- xen/common/libfdt/Makefile | 13 +- xen/include/Makefile | 16 +- xen/scripts/Kbuild.include | 107 ++++++++++++ xen/tools/compat-build-header.py | 52 +++++- xen/tools/compat-build-source.py | 8 +- xen/tools/symbols.c | 20 ++- xen/xsm/flask/Makefile | 19 ++- xen/xsm/flask/ss/Makefile | 2 +- 24 files changed, 809 insertions(+), 328 deletions(-) create mode 100644 docs/misc/xen-makefiles/makefiles.rst copy xen/arch/arm/{Rules.mk => arch.mk} (85%) copy xen/arch/x86/{Rules.mk => arch.mk} (87%) -- Anthony PERARD
