Subject: [cocci] [PATCH v2 00/11] kbuild: support building external modules in a separate build directory
Date: Sun, 10 Nov 2024 10:34:28 +0900	[thread overview]
Message-ID: <20241110013649.34903-1-masahiroy@kernel.org> (raw)


There has been a long-standing request to support building external
modules in a separate build directory.

In v2, 05/11 introduces a 'srcroot' variable.
(I am not sure if this is the best name, though)
$(srcroot) points to the top of the source directory.
  - When M= is not given, it is the top of the kernel source
  - When M= is given, it is the top of the external module source


Masahiro Yamada (11):
  kbuild: replace two $(abs_objtree) with $(CURDIR) in top Makefile
  kbuild: add $(objtree)/ prefix to some in-kernel build artifacts
  kbuild: rename abs_objtree to abs_output
  kbuild: use 'output' variable to create the output directory
  kbuild: change working directory to external module directory with M=
  kbuild: remove extmod_prefix, MODORDER, MODULES_NSDEPS variables
  kbuild: support building external modules in a separate build
    directory
  kbuild: support -fmacro-prefix-map for external modules
  kbuild: use absolute path in the generated wrapper Makefile
  kbuild: make wrapper Makefile more convenient for external modules
  kbuild: allow to start building external modules in any directory
