If a single-object module # is turned into a multi-object module, $^ (and therefore $(real-prereqs) # as well) contains header files recorded in the *.cmd file. Such headers # must be filtered out. # # Now that a DTB can be built either from a single source or multiple # source files, the same issue can occur. # # Consider the following scenario: # # First, foo.dtb is implemented as a single-blob device tree. # # The code looks something like this: # # [Sample Code 1] # # Makefile: # # dtb-y += foo.dtb # # foo.dts: # # #include <dt-bindings/gpio/gpio.h> # /dts-v1/; # / { }; # # When it is compiled, .foo.dtb.cmd records that foo.dtb depends on # scripts/dtc/include-prefixes/dt-bindings/gpio/gpio.h. # # Later, foo.dtb is split into a base and an overlay. The code looks # something like this: # # [Sample Code 2] # # Makefile: # # dtb-y += foo.dtb # foo-dtbs := foo-base.dtb foo-addon.dtbo # # foo-base.dts: # # #include <dt-bindings/gpio/gpio.h> # /dts-v1/; # / { }; # # foo-addon.dtso: # # /dts-v1/; # /plugin/; # / { }; # # If you rebuild foo.dtb without 'make clean', you will get this error: # # Overlay 'scripts/dtc/include-prefixes/dt-bindings/gpio/gpio.h' is incomplete # # $(real-prereqs) contains not only foo-base.dtb and foo-addon.dtbo but # also scripts/dtc/include-prefixes/dt-bindings/gpio/gpio.h, which is # passed to scripts/dtc/fdtoverlay. # # Fixes: 15d16d6dadf6 ("kbuild: Add generic rule to apply fdtoverlay") # Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 ab6aaea6835b5d6da15f4d14d4af8b1a9a1c609b # make -s -j 160 ARCH=x86_64 O=/kisskb/build/kbuild_allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig # < make -s -j 160 ARCH=x86_64 O=/kisskb/build/kbuild_allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 160 ARCH=x86_64 O=/kisskb/build/kbuild_allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 160 ARCH=x86_64 O=/kisskb/build/kbuild_allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- WARNING: modpost: drivers/virt/coco/sev-guest/sev-guest: section mismatch in reference: sev_guest_driver+0x10 (section: .data) -> sev_guest_remove (section: .exit.text) Completed OK # rm -rf /kisskb/build/kbuild_allmodconfig_x86_64-gcc8 # Build took: 0:18:30.594264
