perf inject: Fix processing of ID index for injected instruction tracing

2019-12-04T15:39:53+00:00

The ID index event is used when decoding, but can result in the following error: $ perf record --aux-sample -e '{intel_pt//,branch-misses}:u' ls $ perf inject -i perf.data -o perf.data.inj --itrace=be $ perf script -i perf.data.inj 0x1020 [0x410]: failed to process type: 69 [No such file or directory] Fix by having 'perf inject' drop the ID index event.

perf inject: Cut AUX area samples

2019-11-22T13:48:13+00:00

After decoding AUX area samples, the AUX area data is no longer needed (having been replaced by synthesized events) so cut it out. Signed-off-by: Adrian Hunter Cc: Jiri Olsa Link: http://lore.kernel.org/lkml/20191115124225.5247-9-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo

perf inject: Make --strip keep evsels

2019-11-06T18:49:40+00:00

create_gcov (refer to the autofdo example in tools/perf/Documentation/intel-pt.txt) now needs the evsels to read the perf.data file. So don't strip them.

perf session: Return error code for perf_session__new() function on failure

2019-09-20T18:58:11+00:00

This patch is to return error code of perf_new_session function on failure instead of NULL. Test Results: Before Fix: $ perf c2c report -input failed to open nput: No such file or directory $ echo $? 0 $ After Fix: $ perf c2c report -input failed to open nput: No such file or directory $ echo $? 254 $ Committer notes: Fix 'perf tests topology' case, where we use that TEST_ASSERT_VAL(..., session), i.e. we need to pass zero in case of failure, which was the case before when NULL was returned by perf_session__new() for failure, but now we need to negate the result of IS_ERR(session) to respect that TEST_ASSERT_VAL) expectation of zero meaning failure.

perf tools: Move event synthesizing routines to separate header

2019-09-20T12:19:22+00:00

Those are the only routines using the perf_event__handler_t typedef and are all related, so move to a separate header to reduce the header dependency tree, lots of places were getting event.h and even stdio.h, limits.h indirectly, so fix those as well.

perf dsos: Move the dsos struct and its methods to separate source files

2019-09-01T01:24:10+00:00

So that we can reduce the header dependency tree further, in the process noticed that lots of places were getting even things like build-id routines and 'struct perf_tool' definition indirectly, so fix all those too.

perf tools: Remove perf.h from source files not needing it

2019-08-29T20:38:32+00:00

With the movement of lots of stuff out of perf.h to other headers we ended up not needing it in lots of places, remove it from those places.

libperf: Move perf_event_attr field from perf's evsel to libperf's perf_evsel

2019-07-29T21:34:45+00:00

Move the perf_event_attr struct fron 'struct evsel' to 'struct perf_evsel'. Committer notes: Fixed up these: tools/perf/arch/arm/util/auxtrace.c tools/perf/arch/arm/util/cs-etm.c tools/perf/arch/arm64/util/arm-spe.c tools/perf/arch/s390/util/auxtrace.c tools/perf/util/cs-etm.c Also cc1: warnings being treated as errors tests/sample-parsing.c: In function 'do_test': tests/sample-parsing.c:162: error: missing initializer tests/sample-parsing.c:162: error: (near initialization for 'evsel.core.cpus') struct evsel evsel = { .needs_swap = false, - .core.attr = { - .sample_type = sample_type, - .read_format = read_format, + .core = { + . attr = { + .sample_type = sample_type, + .read_format = read_format, + }, [perfbuilder@a70e4eeb5549 /]$ gcc --version |& head -1 gcc (GCC) 4.4.7 Also we don't need to include perf_event.h in tools/perf/lib/include/perf/evsel.h, forward declaring 'struct perf_event_attr' is enough. And this even fixes the build in some systems where things are used somewhere down the include path from perf_event.h without defining __always_inline.

perf evlist: Rename perf_evlistremove() to evlistremove()

2019-07-29T21:34:43+00:00
