From a132b784db68b543fd2745973cd8b5edf8e9bde4 Mon Sep 17 00:00:00 2001 From: Yang Jihong Date: Sat, 16 Sep 2023 09:16:41 +0000 Subject: [PATCH] perf test: Fix test-record-dummy-C0 failure for supported PERF_FORMAT_LOST feature kernel For kernel that supports PERF_FORMAT_LOST, attr->read_format has PERF_FORMAT_LOST bit. Update expected value of attr->read_format of test-record-dummy-C0 for this scenario.
