From mboxrd@z Thu Jan 1 00:00:00 1970 From: Thomas Richter Subject: [PATCH 1/3] perf: fix incorrect sample_type value for perf stat tests Date: Tue, 6 Jun 2017 16:31:54 +0200 Message-ID: <20170606143156.10471-2-tmricht@linux.vnet.ibm.com> References: <20170606143156.10471-1-tmricht@linux.vnet.ibm.com> Return-path: In-Reply-To: <20170606143156.10471-1-tmricht@linux.vnet.ibm.com> Sender: linux-perf-users-owner@vger.kernel.org List-Archive: List-Post: To: linux-s390@vger.kernel.org, linux-perf-users@vger.kernel.org, acme@kernel.org, jolsa@redhat.com Cc: Thomas Richter List-ID: Test case 14 runs 'perf stat' command to execute all tests/attr/test-stat* test cases. They all fail with a mismatch in sample_type attribute, for example: running './tests/attr//test-stat-basic' ... compare matchng [event:base-stat] to [event-0-0-4] ... [sample_type] 0 65536 ->FAIL The reason for the failure is in create_perf_stat_counter() in file builtin-stat.c. When command 'perf stat record -o -' is used the value of perf_event_stat.sample_type is not changed. All other invocations of 'perf stat' change this member to PERF_SAMPLE_IDENTIFIER (2^16). None of the test-stat-* tests are invoked with 'perf stat record -o -' and the sample_type comparion fails. Fix this by changing the expected value for attribute sample_type in the base_stat file.
