scripts/dtc: Call pkg-config POSIXly correct

2022-04-08T12:40:15Z

[ Upstream commit a8b309ce9760943486e0585285e0125588a31650 ] Running with POSIXLY_CORRECT=1 in the environment the scripts/dtc build fails, because pkg-config doesn't output anything when the flags come after the arguments.

scripts/dtc: dtx_diff: remove broken example from help text

2022-01-27T09:54:35Z

commit d8adf5b92a9d2205620874d498c39923ecea8749 upstream. dtx_diff suggests to use <(...) syntax to pipe two inputs into it, but this has never worked: The /proc/self/fds/... paths passed by the shell will fail the `[ -f "${dtx}" ] && [ -r "${dtx}" ]` check in compile_to_dts, but even with this check removed, the function cannot work: hexdump will eat up the DTB magic, making the subsequent dtc call fail, as a pipe cannot be rewound. Simply remove this broken example, as there is already an alternative one that works fine.

scripts/dtc: only append to HOST_EXTRACFLAGS instead of overwriting

2020-09-29T20:48:08Z

When building with $ HOST_EXTRACFLAGS=-g make the expectation is that host tools are built with debug informations. This however doesn't happen if the Makefile assigns a new value to the HOST_EXTRACFLAGS instead of appending to it. So use += instead of := for the first assignment.

kbuild: introduce hostprogs-always-y and userprogs-always-y

2020-08-09T16:32:59Z

To build host programs, you need to add the program names to 'hostprogs' to use the necessary build rule, but it is not enough to build them because there is no dependency. There are two types of host programs: built as the prerequisite of another (e.g. gen_crc32table in lib/Makefile), or always built when Kbuild visits the Makefile (e.g. genksyms in scripts/genksyms/Makefile). The latter is typical in Makefiles under scripts/, which contains host programs globally used during the kernel build. To build them, you need to add them to both 'hostprogs' and 'always-y'. This commit adds hostprogs-always-y as a shorthand. The same applies to user programs. net/bpfilter/Makefile builds bpfilter_umh on demand, hence always-y is unneeded. In contrast, programs under samples/ are added to both 'userprogs' and 'always-y' so they are always built when Kbuild visits the Makefiles. userprogs-always-y works as a shorthand.

scripts/dtc: use pkg-config to include in non-standard path

2020-06-08T19:14:00Z

Commit 067c650c456e ("dtc: Use pkg-config to locate libyaml") added 'pkg-config --libs' to link libyaml installed in a non-standard location. yamltree.c includes , but that commit did not add the search path for . If /usr/include/yaml.h does not exist, it fails to build. A user can explicitly pass HOSTCFLAGS to work around it, but the policy is not consistent. There are two ways to deal with libraries in a non-default location. [1] Use HOSTCFLAGS and HOSTLDFLAGS for additional search paths for headers and libraries. They are documented in Documentation/kbuild/kbuild.rst $ make HOSTCFLAGS='-I /include' HOSTLDFLAGS='-L /lib' [2] Use pkg-config 'pkg-config --cflags' for querying the header search path 'pkg-config --libs' for querying the lib and its path If we go with pkg-config, use [2] consistently. Do not mix up [1] and [2]. Signed-off-by: Masahiro Yamada Signed-off-by: Rob Herring

kbuild: check libyaml installation for 'make dt_binding_check'

2020-04-17T15:45:23Z

If you run 'make dtbs_check' without installing the libyaml package, the error message "dtc needs libyaml ..." is shown. This should be checked also for 'make dt_binding_check' because dtc needs to validate *.example.dts extracted from *.yaml files. It is missing since commit 4f0e3a57d6eb ("kbuild: Add support for DT binding schema checks"), but this fix-up is applicable only after commit e10c4321dc1e ("kbuild: allow to run dt_binding_check and dtbs_check in a single command"). I gave the Fixes tag to the latter in case somebody is interested in back-porting this.
