From 67c81d8fef2b01023fadc32eb2b36ab614f27221 Mon Sep 17 00:00:00 2001 From: Anders Roxell Date: Mon, 27 Aug 2018 13:21:49 +0200 Subject: [RFC PATCH] config: add all_abi config fragments Collect all fragment needed for testing kselftest, libhugetlbfs and ltp into all_abi.config. The idea is to enable as much as possible and preferably as modules. The idea is to be able to run 'make defconfig all_abi.config' and that should enable the base fragments for whats needed when running tests. Signed-off-by: Anders Roxell --- Hi, I've done this work against a next tag: next-20180827. I've created this patch to align the testing effort. With this fragment in upstream the goal would be to enable kernelci to do 'make defconfig all_abi.config' to enable all tests at once. To enable the same today something like this would be necessary to do 'wget (LTP [1] libhugetlbfs [2]) && make defconfig && ./scripts/kconfig/merge_config.sh .config LTP libhugetlbfs && make kselftest-merge' And even then it wont be ok since the LTP file [1] is out of date regards to the fragments there. In this RFC I added where I took the fragments from (for kselftest tools/testing/selftests/*/config, LTP [1], libhugetlbfs [2]), thats why its a lot of comments in the file, that will be removed and I will order them in alphabetic order. Should we enable these fragments in all_abi.config: - CONFIG_SLUB is enabled on both arm64 and x86. - CONFIG_SECURITY_SELINUX are default on x86 and CONFIG_SECURITY_DAC on arm64 any idea what should be the default? - CONFIG_DRM 'y' on x86, 'm' on arm64 its the same with CONFIG_IPV6. Maybe I should remove the CONFIG_EXT4_FS from all_abi.config also, since its in the default config ? To be sure or should we go with what is in the defconfig and then just add as much as possible as modules ? And add try to upstream this patch at the same time maybe [3] so we don't "break" whats in the "first" config if someone does 'make my-own-config all-abi.config' ? Can you see if I need to add any other fragments, update changelog, or anything else before I redo it to an alphabetic order ?
