Subject: [PATCH RFD] selftests: create test-specific kconfig fragments
Date: Sat, 14 Nov 2015 12:57:13 +0800	[thread overview]
Message-ID: <1447477033-7522-1-git-send-email-bamvor.zhangjian@linaro.org> (raw)

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
