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.

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 evsel: Rename struct perf_evsel to struct evsel

2019-07-29T21:34:42+00:00

Rename struct perf_evsel to struct evsel, so we don't have a name clash when we add struct perf_evsel in libperf. Committer notes: Added fixes for arm64, provided by Jiri.

perf db-export: Also export thread's current comm

2019-07-10T15:14:07+00:00

Currently, the initial comm of the main thread is exported. Export also a thread's current comm. That better supports the tracing of multi-threaded applications that set different comms for different threads to make it easier to distinguish them.

Move call to db_export__comm_thread() from db_export__thread() into db_export__sample() because it makes the code easier to understand, and add explanatory comments.
