perf maps: Merge 'struct maps' with 'struct map_groups'

2019-11-26T14:07:46+00:00

And pick the shortest name: 'struct maps'.

The split existed because we used to have two groups of maps, one for
functions and one for variables, but that only complicated things,
sometimes we needed to figure out what was at some address and then had
to first try it on the functions group and if that failed, fall back to
the variables one.

That split is long gone, so for quite a while we had only one struct
maps per struct map_groups, simplify things by combining those structs.

First patch is the minimum needed to merge both, follow up patches will
rename 'thread->mg' to 'thread->maps', etc.

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 tool: Rename perf_tool::bpf_event to bpf

2019-08-26T22:39:11+00:00

No need for that _event suffix, do just like all the other meta event
handlers and suppress that suffix.

perf tools: Rename perf_event::bpf_event to perf_event::bpf

2019-08-26T22:39:11+00:00

Just like all the other meta events, that extra _event suffix is just
redundant, ditch it.

libperf: Rename the PERF_RECORD_ structs to have a "perf" suffix

2019-08-26T22:39:11+00:00

Even more, to have a "perf_record_" prefix, so that they match the
PERF_RECORD_ enum they map to.

perf record: Move record_opts and other record decls out of perf.h

2019-08-26T14:58:22+00:00

And into a separate util/record.h, to better isolate things and make
sure that those who use record_opts and the other moved declarations
are explicitly including the necessary header.

perf evlist: Rename struct perf_evlist to struct evlist

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

Rename struct perf_evlist to struct evlist, so we don't have a name
clash when we add struct perf_evlist in libperf.

perf bpf: Show more BPF program info in print_bpf_prog_info()

2019-03-21T14:27:04+00:00

This patch enables showing bpf program name, address, and size in the
header.

Before the patch:

  perf report --header-only
  ...
  # bpf_prog_info of id 9
  # bpf_prog_info of id 10
  # bpf_prog_info of id 13

After the patch:

  # bpf_prog_info 9: bpf_prog_7be49e3934a125ba addr 0xffffffffa0024947 size 229
  # bpf_prog_info 10: bpf_prog_2a142ef67aaad174 addr 0xffffffffa007c94d size 229
  # bpf_prog_info 13: bpf_prog_47368425825d7384_task__task_newt addr 0xffffffffa0251137 size 369

Committer notes:

Fix the fallback definition when HAVE_LIBBPF_SUPPORT is not defined,
i.e. add the missing 'static inline' and add the __maybe_unused to the
args. Also add stdio.h since we now use FILE * in bpf-event.h.
