[PATCH v2 0/2] Fix KSFT toplevel makefile behaviour

by Cristian Marussi

Hi so this series carries two small fixes to the toplevel KSelfTest makefile which I found useful especially while attempting to run the suite in automation. [1/2] While it is already possible to specify a limited list of TARGETS to run, it is not instead easily possible to state a list of targets NOT to run (say due to specific instability issues). Moreover providing such a skip list through a stripped down list of TARGETS it is cumbersome and fragile since this poses the risk to stick to an old stale stripped TARGETS list once upstream decides to add more default targets. A new SKIP_TARGETS Makefile variable is provided by this patch to easily specify a skiplist for target subsystems. [2/2] Currently when some target fails to build, KSFT Makefile just carries on building as much subsystems as it can: unfortunately this is not properly reflected also in the generation of the runlist inside run_kselftest.sh. This patch rectifies this behaviour checking for the existence of a target directory in the INSTALL_PATH before adding the related snippet to the run_kselftest.sh script. Thanks Cristian Changelog v1 --> v2 - added Documentation - various typos fixed - added a proper override when filtering-out SKIP_TARGETS from TARGETS to make it work also when TARGETS is provided too from the cmdline Cristian Marussi (2): kselftest: add capability to skip chosen TARGETS kselftest: exclude failed TARGETS from runlist Documentation/dev-tools/kselftest.rst | 11 +++++++++++ tools/testing/selftests/Makefile | 11 +++++++++++ 2 files changed, 22 insertions(+) -- 2.17.1

bug in KBUILD_OUTPUT handling - for relative paths in kselftest

by Tim.Bird＠sony.com

I found a bug in kselftest KBUILD_OUTPUT handling. The following works: $ cd /home/tbird/work/linux $ export KBUILD_OUTPUT=/home/tbird/work/kbuild $ yes '' | make localmodconfig $ make TARGETS=size kselftest But this doesn't work: $ cd /home/tbird/work/linux $ export KBUILD_OUTPUT=../kbuild $ yes '' | make localmodconfig $ make TARGETS=size kselftest I see the following: make[1]: Entering directory '/home/tbird/work/kbuild' make --no-builtin-rules INSTALL_HDR_PATH=$BUILD/usr \ ARCH=x86 -C ../../.. headers_install INSTALL ../kbuild/kselftest/usr/include gcc -static -ffreestanding -nostartfiles -s get_size.c -o ../kbuild/kselftest/size/get_size /usr/bin/ld: cannot open output file ../kbuild/kselftest/size/get_size: No such file or directory collect2: error: ld returned 1 exit status ../lib.mk:138: recipe for target '../kbuild/kselftest/size/get_size' failed make[3]: *** [../kbuild/kselftest/size/get_size] Error 1 Makefile:136: recipe for target 'all' failed make[2]: *** [all] Error 2 /home/tbird/work/linux/Makefile:1240: recipe for target 'kselftest' failed make[1]: *** [kselftest] Error 2 make[1]: Leaving directory '/home/tbird/work/kbuild' Makefile:179: recipe for target 'sub-make' failed make: *** [sub-make] Error 2 This is due to the relative path for KBUILD_OUTPUT being handled incorrectly (I believe) in tools/testing/selftests/Makefile. There are these lines in the Makefile, which are responsible for creating the output directory: BUILD_TARGET=$$BUILD/$$TARGET mkdir $$BUILD_TARGET -p But these are executed from working directory tools/testing/selftests, so the 'size' directory gets created at tools/testing/kbuild/kselftest/size, instead of /home/tbird/work/kbuild/kselftest/size. I can add some code to the Makefile to change the assignment of the variable BUILD, so that if it is a relative path it is relative to $(top_srcdir) instead of the current directory. But I wanted to check and make sure that I'm not breaking anyone else's workflow. I'm not sure what the expectation would be for someone who did this: $ export KBUILD_OUTPUT=../kbuild ; make -C tools/testing/selftests run_tests But I assume if someone is running the kernel's 'make' from the top-level kernel source directory, and they have a relative KBUILD_OUTPUT directory, then they want that output directory to be relative to the top-level directory and not somewhere else. Should I just code up something for review? I use relative KBUILD_OUTPUT paths for a number of my kernel build scripts, and right now these are incompatible with kselftests. Thanks, -- Tim

[PATCH 1/2] kselftest: add capability to skip chosen TARGETS

by Cristian Marussi

Let the user specify an optional TARGETS skiplist through the new optional SKIP_TARGETS Makefile variable. It is easier to skip at will a reduced and well defined list of possibly problematic targets with SKIP_TARGETS then to provide a partially stripped down list of good targets using the usual TARGETS variable.
