From 0fd4008ed755c52d85117302a3c2c108b2958420 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Thu, 3 Dec 2015 09:34:14 +0100 Subject: [PATCH] perf test: Use machine__new_host in mmap thread code reading test This is more straightforward than what we have now. It also fixes a segfault within machine__exit, that's caused by not creating kernel maps for machine.. We're calling machine__destroy_kernel_maps in machine__exit since commit: ebe9729c8c31 perf machine: Fix to destroy kernel maps when machine exits Signed-off-by: Jiri Olsa Acked-by: Namhyung Kim Cc: Adrian Hunter Cc: David Ahern Cc: Masami Hiramatsu Cc: Peter Zijlstra Cc: Wang Nan Link: http://lkml.kernel.org/r/1449131658-1841-4-git-send-email-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/tests/code-reading.c | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-) diff --git a/tools/perf/tests/code-reading.c b/tools/perf/tests/code-reading.c index 4417b6a..26182ff 100644 --- a/tools/perf/tests/code-reading.c +++ b/tools/perf/tests/code-reading.c @@ -433,7 +433,6 @@ enum { static int do_test_code_reading(bool try_kcore) { - struct machines machines; struct machine *machine; struct thread *thread; struct record_opts opts = { @@ -459,8 +458,7 @@ static int do_test_code_reading(bool try_kcore) pid = getpid(); - machines__init(&machines); - machine = &machines.host; + machine = machine__new_host(); ret = machine__create_kernel_maps(machine); if (ret < 0) { @@ -594,9 +592,8 @@ out_err: cpu_map__put(cpus); thread_map__put(threads); } - machines__destroy_kernel_maps(&machines); machine__delete_threads(machine); - machines__exit(&machines); + machine__delete(machine); return err; } -- 2.7.4
