perf addr_location: Rename al->mg to al->maps

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

One more step on the merge of 'struct maps' with 'struct map_groups'. Cc: Adrian Hunter Cc: Andi Kleen Cc: Jiri Olsa Cc: Namhyung Kim Link: https://lkml.kernel.org/n/tip-foo95pyyp3bhocbt7yd8qrvq@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf callchain: Use 'struct map_symbol' in 'struct callchain_cursor_node'

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

To ease passing around map+symbol, just like done for other parts of the tree recently. Cc: Adrian Hunter Cc: Andi Kleen Cc: Jiri Olsa Cc: Namhyung Kim Signed-off-by: Arnaldo Carvalho de Melo

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 scripting engines: Iterate on tep event arrays directly

2019-10-18T15:07:46+00:00

Instead of calling a useless (and broken) helper function to get the next event of a tep event array, just get the array directly and iterate over it. Note, the broken part was from trace_find_next_event() which after this will no longer be used, and can be removed. Committer notes: This fixes a segfault when generating python scripts from perf.data files with multiple tracepoint events, i.e. the following use case is fixed by this patch: # perf record -e sched:* sleep 1 [ perf record: Woken up 31 times to write data ] [ perf record: Captured and wrote 0.031 MB perf.data (9 samples) ] # perf script -g python Segmentation fault (core dumped) # Reported-by: Daniel Bristot de Oliveira Signed-off-by: Steven Rostedt (VMware) Tested-by: Arnaldo Carvalho de Melo Cc: Andrew Morton Cc: Jiri Olsa Cc: Namhyung Kim Cc: Tzvetomir Stoyanov Cc: linux-trace-devel@vger.kernel.org Link: http://lkml.kernel.org/r/20191017153733.630cd5eb@gandalf.local.home Link: http://lore.kernel.org/lkml/20191017210636.061448713@goodmis.org Signed-off-by: Arnaldo Carvalho de Melo

perf env: Remove needless cpumap.h header

2019-09-20T12:19:21+00:00

Only a 'struct perf_cmp_map' forward allocation is necessary, fix the places that need the header but were getting it indirectly, by luck, from env.h.

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. Cc: Adrian Hunter Cc: Jiri Olsa Cc: Namhyung Kim Link: https://lkml.kernel.org/n/tip-9h6dg6lsqe2usyqjh5rrues4@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

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: Add perf_thread_map__nr/perf_thread_map__pid functions

2019-08-22T20:16:57+00:00

So it's part of libperf library as basic functions operating on perf_thread_map objects.

perf scripting python: Add missing counts.h header

2019-08-22T20:16:57+00:00

It is getting this via evsel.h, that don't strictly need counts.h, just forward declarations for some structs, so add it here before we remove it from there.
