From b73f50ffd4bddcd42b312a6c2b3d990f2cde7bf7 Mon Sep 17 00:00:00 2001 From: David Gow Date: Fri, 27 Feb 2026 18:56:49 +0800 Subject: [PATCH] kunit: tool: Recommend --raw_output=all if no KTAP found If no KTAP header is found in the kernel output (e.g., because the kernel crashed before the KUnit executor was run), it's very useful to re-run the test with --raw_output=all, as that will show any error output (such as a stacktrace, log message, BUG, etc). This is not particularly intuitive, however, as --raw_output=all is not well known. Add an extra log line to advertise --raw_output=all in this case, as it's a terrible user experience to just get "Did any KUnit tests run?"
