There is a discussion about improving the usability of kselftest by
creating test-specific kconfig in recent kernel Summit. Furthormore,
there are different approaches to do it:
1) keep test-specific kconfig fragments inside each selftest so that
merge_configs.sh could build up a kernel that can test the specific
or all feature(s).
2) In the main menu, have an additional option/flag for each feature
that should be enabled when ksefltests are wanted. Similar to the
CONFIG_COMPILE_TEST flag.
This patch try to do option 1. Hope it is a good start for
discussion. User could use these configs with merge_config.sh script:
Enable config for specific testcases:
(export ARCH=xxx #for cross compiling)
./scripts/kconfig/merge_config.sh .config \
tools/testing/selftests/xxx/config
Enable configs for all testcases:
(export ARCH=xxx #for cross compiling)
./scripts/kconfig/merge_config.sh .config \
tools/testing/selftests/*/config

Before you do, do you want to try adding a top-level target that does the merge, something like: $ make kselftest-mergeconfig Or some other better name. cheers ^ permalink raw reply [flat|nested] 7+ messages in thread

Yeah sorry that wasn't very clear. I meant that it would essentialy do your logic to merge all the config fragments: ./scripts/kconfig/merge_config.sh .config tools/testing/selftests/*/config You'll probably need to be more careful with $(srctree) vs $(objtree) etc. Have a look at the merge_into_defconfig rule in arch/powerpc/Makefile for an example. cheers ^ permalink raw reply [flat|nested] 7+ messages in thread
