From c99ac00c2450f2412456fc1444a52acfb48856fa Mon Sep 17 00:00:00 2001 From: Daniel Latypov Date: Fri, 2 Sep 2022 13:22:48 -0700 Subject: [PATCH] kunit: tool: rename all_test_uml.config, use it for --alltests Context: 1. all_tests_uml.config used to be UML specific back when users to manually specify CONFIG_VIRTIO_UML=y to enable CONFIG_PCI=y. 2. --alltests used allyesconfig along with a curated list of options to disable. 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.
