From 5339792bd64bd1605d3d51f8e52e94dfc385959b Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ilpo=20J=C3=A4rvinen?= Date: Fri, 16 Feb 2024 09:34:56 +0100 Subject: [PATCH] selftests/resctrl: Add test groups and name L3 CAT test L3_CAT MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit To select test to run -t parameter can be used. However, -t cat currently maps to L3 CAT test which will be confusing after more CAT related tests will be added. Allow selecting tests as groups and call L3 CAT test "L3_CAT", "CAT" group will enable all CAT related tests.
