Patch series available in this git branch: https://xenbits.xen.org/git-http/people/aperard/xen-unstable.git br.build-system-xen-v2
series is based on "[XEN PATCH v3 0/6] xen: Kconfig update with few extra" v2: Rather than taking Kbuild and making it work with Xen, the v2 takes the opposite approach of slowly transforming our current build system into Kbuild. That have the advantage of keeping all the feature we have and making the patches much easier to review. Kconfig update is done in an other patch series. v1: https://lists.xenproject.org/archives/html/xen-devel/2019-10/msg01609.html 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. XXX Known issue - make dist-tests is broken. I'll fix that latter. - efi build maybe broken (xen doesn't boot on albana which looks like to be one of the uefi host) Cheers, Anthony PERARD (12): xen/build: Remove left over -DMAX_PHYS_IRQS xen/build: Use obj-y += subdir/ instead of subdir-y xen/build: use $(clean) shorthand for clean targets xen/build: extract clean target from Rules.mk xen/include: remove include of Config.mk xen/test/livepatch: remove include of Config.mk xen/build: run targets csopes,tags,.. without Rules.mk xen/build: make tests in test/ directly xen/build: include include/config/auto.conf in main Makefile xen/build: use new $(c_flags) and $(a_flags) instead of $(CFLAGS) xen/build: introduce ccflags-y and CFLAGS_$@ xen/build: have the root Makefile generates the CFLAGS xen/Makefile | 211 +++++++++++++++++++++------ xen/Rules.mk | 135 +++++------------ xen/arch/arm/Makefile | 28 ++-- xen/arch/arm/Rules.mk | 93 ------------ xen/arch/arm/arch.mk | 88 +++++++++++ xen/arch/arm/arm32/Makefile | 2 +- xen/arch/arm/arm64/Makefile | 2 +- xen/arch/arm/efi/Makefile | 2 +- xen/arch/x86/Makefile | 46 +++--- xen/arch/x86/Rules.mk | 91 +----------- xen/arch/x86/acpi/Makefile | 2 +- xen/arch/x86/arch.mk | 87 +++++++++++ xen/arch/x86/cpu/Makefile | 4 +- xen/arch/x86/efi/Makefile | 2 +- xen/arch/x86/guest/Makefile | 4 +- xen/arch/x86/hvm/Makefile | 6 +- xen/arch/x86/mm/Makefile | 10 +- xen/arch/x86/mm/hap/Makefile | 6 +- xen/arch/x86/mm/shadow/Makefile | 6 +- xen/arch/x86/x86_64/Makefile | 2 +- xen/common/Makefile | 8 +- xen/common/libelf/Makefile | 4 +- xen/common/libfdt/Makefile | 4 +- xen/drivers/Makefile | 14 +- xen/drivers/acpi/Makefile | 6 +- xen/drivers/passthrough/Makefile | 8 +- xen/drivers/passthrough/vtd/Makefile | 2 +- xen/include/Makefile | 4 +- xen/lib/Makefile | 2 +- xen/scripts/Kbuild.include | 10 ++ xen/scripts/Makefile.clean | 33 +++++ xen/test/livepatch/Makefile | 2 - xen/xsm/Makefile | 2 +- xen/xsm/flask/Makefile | 4 +- xen/xsm/flask/ss/Makefile | 2 +- 35 files changed, 519 insertions(+), 413 deletions(-) create mode 100644 xen/arch/arm/arch.mk create mode 100644 xen/arch/x86/arch.mk create mode 100644 xen/scripts/Makefile.clean -- Anthony PERARD _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
