perf tests: Adding automated parsing tests for group :GH modifiers

2013-02-06T21:09:28Z

The ':GH' group modifier handling was just recently fixed, adding some autommated tests to keep it that way. Adding tests for following events: "{cycles,cache-misses:G}:H" "{cycles,cache-misses:H}:G" "{cycles:G,cache-misses:H}:u" "{cycles:G,cache-misses:H}:uG" Plus fixing test__group2 test.

perf sort: Make setup_sorting returns an error code

2013-02-06T21:09:26Z

Currently the setup_sorting() is called for parsing sort keys and exits if it failed to add the sort key. As it's included in libperf it'd be better returning an error code rather than exiting application inside of the library.

perf tests: Add group test conditions

2013-01-31T16:07:44Z

As some new fields for handling groups added, check them to be sure to have valid values in test__group* cases.

perf tools, powerpc: Fix compile warnings in tests/attr.c

2013-01-30T13:37:14Z

We print several '__u64' quantities using '%llu'. On powerpc, we by default include ' which results in __u64 being an unsigned long. This causes compile warnings which are treated as errors due to '-Werror'. By defining __SANE_USERSPACE_TYPES__ we include and define __u64 as unsigned long long. Changelog[v2]: [Michael Ellerman] Use __SANE_USERSPACE_TYPES__ and avoid PRIu64 format specifier - which as Jiri Olsa pointed out, breaks on x86-64.

perf evsel: Fix memory leaks on evsel->counts

2013-01-30T13:37:04Z

The ->counts field was never freed in the current code. Add perf_evsel__free_counts() function to free it properly.

perf test: Allow skipping tests

2013-01-24T19:40:53Z

Sometimes a test is problematic for some reason and one wants to skip it, for instance: [root@sandy ~]# perf test 1: vmlinux symtab matches kallsyms : Ok 2: detect open syscall event : Ok 3: detect open syscall event on all cpus : Ok 4: read samples using the mmap interface : Ok 5: parse events tests : Warning: bad op token { Warning: bad op token { Warning: bad op token { Warning: bad op token { Warning: bad op token { Warning: function is_writable_pte not defined Segmentation fault (core dumped) So now we can use -s/--skip while the problematic tests are being fixed, allowing us to test all the other entries: [root@sandy ~]# perf test -s 5 1: vmlinux symtab matches kallsyms : Ok 2: detect open syscall event : Ok 3: detect open syscall event on all cpus : Ok 4: read samples using the mmap interface : Ok 5: parse events tests : Skip (user override) 6: x86 rdpmc test : Ok 7: Validate PERF_RECORD_* events & perf_sample fields : Ok 8: Test perf pmu format parsing : Ok 9: Test dso data interface : Ok 10: roundtrip evsel->name check : Ok 11: Check parsing of sched tracepoints fields : Ok 12: Generate and check syscalls:sys_enter_open event fields: Ok 13: struct perf_event_attr setup : Ok 14: Test matching and linking mutliple hists : Ok 15: Try 'use perf' in python, checking link problems : Ok [root@sandy ~]# Cc: David Ahern Cc: Frederic Weisbecker Cc: Jiri Olsa Cc: Mike Galbraith Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/n/tip-klzd8p57jzdryafqkmlppcb1@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Fix usage of __ in event parsing struct names

2013-01-24T19:40:51Z

In tools/perf we use a convention where __ separates the struct name from the function name for functions that operate on a struct instance. Fix this usage by removing it from the struct names and fix also the associated functions.
