perf map: Add accessor for dso

2023-04-04T19:41:57+00:00

Later changes will add reference count checking for struct map, with
dso being the most frequently accessed variable. Add an accessor so
that the reference count check is only necessary in one place.

Additional changes:
 - add a dso variable to avoid repeated map__dso calls.
 - in builtin-mem.c dump_raw_samples, code only partially tested for
   dso == NULL. Make the possibility of NULL consistent.
 - in thread.c thread__memcpy fix use of spaces and use tabs.

perf maps: Add functions to access maps

2023-04-04T18:45:38+00:00

Introduce functions to access struct maps. These functions reduce the
number of places reference counting is necessary. While tidying APIs do
some small const-ification, in particlar to unwind_libunwind_ops.

Committer notes:

Fixed up tools/perf/util/unwind-libunwind.c:

-               return ops->get_entries(cb, arg, thread, data, max_stack);
+               return ops->get_entries(cb, arg, thread, data, max_stack, best_effort);

perf scripting python: Add 'addr_location' for 'addr'

2021-05-25T13:07:17+00:00

If sample addr correlates to a symbol, add  "addr_dso", "addr_symbol", and
"addr_symoff" to python scripting.

perf script: Add branch types for VM-Entry and VM-Exit

2021-02-18T19:12:51+00:00

In preparation to support Intel PT decoding of virtual machine traces, add
branch types for VM-Entry and VM-Exit.

Note they are both treated as "calls" because the VM-Exit transfers control
to a different address.

To ease passing around map+symbol, just like done for other parts of the

perf tools: Add map_groups to 'struct addr_location'

2019-11-12T11:20:53+00:00

From there we can get al->mg->machine, so replace that field with the
more useful 'struct map_groups' that for now we're obtaining from
al->map->groups, and that is one thing getting into the way of maps
being fully shareable.

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.
