From c9ee780f2736b7a149658b0cd8c8389da23e190a Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 6 Aug 2013 23:28:06 +1000 Subject: [PATCH] perf tests: Add tests of new pinned modifier Add a negative test to test__checkevent_pmu_events() to get lots of coverage of the negative case, ie. when the modifier is not specified. Add a test of a single event, and of the group case.
