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 cs-etm: Fix definition of macro TO_CS_QUEUE_NR

2019-11-06T18:43:05+00:00

Macro TO_CS_QUEUE_NR definition has a typo, which uses 'trace_id_chan'
as its parameter, this doesn't match with its definition body which uses
'trace_chan_id'.  So renames the parameter to 'trace_chan_id'.

It's luck to have a local variable 'trace_chan_id' in the function
cs_etm__setup_queue(), even we wrongly define the macro TO_CS_QUEUE_NR,
the local variable 'trace_chan_id' is used rather than the macro's
parameter 'trace_id_chan'; so the compiler doesn't complain for this
before.

After renaming the parameter, it leads to a compiling error due
cs_etm__setup_queue() has no variable 'trace_id_chan'.  This patch uses
the variable 'trace_chan_id' for the macro so that fixes the compiling
error.

libperf: Move 'id' from 'struct evsel' to 'struct perf_evsel'

2019-09-25T12:51:47+00:00

Move the 'id' array from 'struct evsel' to libperf's 'struct perf_evsel'.

Committer note:

Fix the tools/perf/util/cs-etm.c build, i.e. aarch64's CoreSight.

perf tools: Move event synthesizing routines to separate .c file

2019-09-20T13:28:21+00:00

For better grouping, in time we may end up making most of these static,
i.e. generalizing the 'perf record' synthesizing code so that based on
the target it can do the right thing and call the needed synthesizers.

perf tools: Remove util.h from where it is not needed

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

Check that it is not needed and remove, fixing up some fallout for
places where it was only serving to get something else.

perf symbols: Move mem_info and branch_info out of symbol.h

2019-09-01T01:27:48+00:00

The mem_info struct goes to mem-events.h and branch_info goes to
branch.h, where they belong, this way we can remove several headers from
symbols.h and trim the include dependency tree more.

perf auxtrace: Uninline functions that touch perf_session

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

So that we don't carry the session.h include directive in auxtrace.h,
which in turn opens a can of worms of files that were getting all sorts
of things via that include, fix them all.

perf tools: Remove needless thread_map.h include directives

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

Now that thread_map.h isn't included by any other header, we can check where
it is really needed, i.e. we can remove it and be sure that it isn't
being obtained indirectly.

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: Rename the PERF_RECORD_ structs to have a "perf" prefix

2019-08-29T11:36:12+00:00

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