kbuild: add a flag to force absolute path for srctree

2019-07-10T15:05:09Z

In old days, Kbuild always used an absolute path for $(srctree). Since commit 890676c65d69 ("kbuild: Use relative path when building in the source tree"), $(srctree) is '.' when O= was not passed from the command line. Yet, using absolute paths is useful in some cases even without O=, for instance, to create a cscope file with absolute path tags. 'O=.' was known to work as a workaround to force Kbuild to use absolute paths even when you are building in the source tree. Since commit 25b146c5b8ce ("kbuild: allow Kbuild to start from any directory"), Kbuild is too clever to be tricked. Even if you pass 'O=.' Kbuild notices you are building in the source tree, then use '.' for $(srctree). So, 'make O=. cscope' is no help to create absolute path tags. We cannot force one or the other according to commit e93bc1a0cab3 ("Revert "kbuild: specify absolute paths for cscope""). Both of relative path and absolute path have pros and cons. This commit adds a new flag KBUILD_ABS_SRCTREE to allow users to choose the absolute path for $(srctree). 'make KBUILD_ABS_SRCTREE=1 cscope' will work as a replacement of 'make O=. cscope'.

scripts/tags.sh: drop SUBARCH support for ARM

2019-07-09T13:01:44Z

Our goal is to have more and more sub-architectures to join the ARM multi-platform, and support them in a single configuration. Remove the ARM SUBARCH support because it is ugly. Signed-off-by: Masahiro Yamada

scripts/tags.sh: fix direct execution of scripts/tags.sh

2019-05-03T14:05:01Z

I thought this script was run via "make tags" etc. but some people run it directly. Prior to commit a9a49c2ad9b9 ("kbuild: use $(srctree) instead of KBUILD_SRC to check out-of-tree build"), in such a usecase, "tree" was set empty since KBUILD_SRC is undefined. Now, "tree" is set to "${srctree}/", which is evaluated to "/". Fix it by taking into account the case where "srctree" is unset.

kbuild: use $(srctree) instead of KBUILD_SRC to check out-of-tree build

2019-04-02T14:28:04Z

KBUILD_SRC was conventionally used for some different purposes: [1] To remember the source tree path [2] As a flag to check if sub-make is already done [3] As a flag to check if Kbuild runs out of tree For [1], we do not need to remember it because the top Makefile can compute it by $(realpath $(dir $(lastword $(MAKEFILE_LIST)))) [2] has been replaced with self-commenting 'sub_make_done'. For [3], we can distinguish in-tree/out-of-tree by comparing $(srctree) and '.' This commit converts [3] to prepare for the KBUILD_SRC removal. Signed-off-by: Masahiro Yamada
