From 0a888078f29930617e6b8aa7e04c3c5c1e9aa689 Mon Sep 17 00:00:00 2001 From: John Garry Date: Wed, 30 Nov 2022 19:01:33 +0800 Subject: [PATCH] perf test: Verify more event members in pmu-events test mainline inclusion from mainline-v5.16-rc1 commit 56be05103a40 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I63VF5 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=56be05103a408b7f56c5e75717b2b23a5adf1ddb -------------------------------------------------------------------------- Function compare_pmu_events() does not compare all struct pmu-events members, so add tests for missing members "name", "event", "aggr_mod", "event", "metric_constraint", and "metric_group", and re-order the tests to match current struct pmu-events member ordering. Also fix uncore_hisi_l3c_rd_hit_cpipe.event member, now that we're actually testing it.
