From d20a6ba5e3be5f8d9002c6c5a5d4dfecc5dc48f9 Mon Sep 17 00:00:00 2001 From: Joe Fradley Date: Tue, 23 Aug 2022 07:24:54 -0700 Subject: kunit: add kunit.enable to enable/disable KUnit test This patch adds the kunit.enable module parameter that will need to be set to true in addition to KUNIT being enabled for KUnit tests to run. The default value is true giving backwards compatibility. However, for the production+testing use case the new config option KUNIT_DEFAULT_ENABLED can be set to N requiring the tester to opt-in by passing kunit.enable=1 to the kernel.

It's only ever worked for brief periods of time and has perennially been broken due to compile issues. Now all_tests_uml.config should work across ~all architectures. Let's instead use this to implement --alltests. Note: if anyone was using all_tests_uml.config, this change breaks them. I think that's unlikely since it was added in 5.19 and was a lot to type: --kunitconfig=tools/testing/kunit/configs/all_tests_uml.config. We could make it a symlink to the new name, but I don't think the caution is warranted here.
