tools lib: Move bitmap.[ch] from tools/perf/ to tools/{lib,include}/

2016-01-08T15:35:46Z

So that lib/find_bit.c doesn't requires anything inside tools/perf/ Cc: Adrian Hunter Cc: Borislav Petkov Cc: David Ahern Cc: George Spelvin Cc: Namhyung Kim Cc: Rasmus Villemoes Cc: Wang Nan Cc: Yury Norov Link: http://lkml.kernel.org/n/tip-7lxe7jgohaac5faodndhdmvk@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

tools lib: Move find_next_bit.c to tools/lib/

2016-01-08T15:35:35Z

The commit that introduced it should've moved it to the same place, plus the 'tools/' prefix, but instead moved it to a bogus tools/lib/util/ directory, being the only file there. Move it to tools/lib/find_bit.c, picking the name for the file where these routines live since: 8f6f19dd5143 ("lib: move find_last_bit to lib/find_next_bit.c") Next step is to make tools/lib/find_bit.c to differ from lib/find_bit.c just in removing what is not used by tools/.

perf python: Add missing files to binding link list

2016-01-07T19:47:11Z

Fixing this problem, introduced recently: $ perf test python 16: Try 'import perf' in python, checking link problems : FAILED! In verbose mode we find out what is missing: $ perf test -v python 16: Try 'import perf' in python, checking link problems : --- start --- test child forked, pid 24894 Traceback (most recent call last): File "", line 1, in ImportError: /tmp/build/perf/python/perf.so: undefined symbol: find_next_bit test child finished with -1 ---- end ---- Try 'import perf' in python, checking link problems: FAILED! $ Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Namhyung Kim Cc: Wang Nan Fixes: f77b57ad4fc4 ("perf cpu_map: Add cpu_map__new_event function") Link: http://lkml.kernel.org/n/tip-rajx0zkz6czdrnvvwf0jp76p@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf stat: Move perf_counts struct and functions into separate object

2015-08-08T17:16:49Z

Moving 'struct perf_counts' and associated functions into separate object, so we could remove stat.c object dependency from python build. It makes the python code to build properly, because it fails to load due to missing stat-shadow.c object dependency if some patches from Kan Liang are applied. So apply this one, then Kan's.

tools: Copy lib/hweight.c from the kernel sources

2015-07-09T19:29:56Z

Instead of accessing it directly, as it uses EXPORT_SYMBOL, that has no meaning in tools/perf and because we removed the stubs for it, i.e. we removed the tools/include/linux/export.h file. This fixes the build for the detached tarball sources cases and removes one more source of entanglement with the kernel sources.

perf tools: Fix the detached tarball wrt rbtree copy

2015-07-09T19:23:57Z

The python binding build process was still looking at the kernel rbtree.c file, so, when doing a in-tree build it would work, but when creating a tarball using tools/perf/MANIFEST as the contents list and then trying to build the resulting detached sources, it failed. Fix it by removing one level of indirection from rbtree.c in the tools/perf/util/python-ext-sources file.

perf thrad_map: Add comm string into array

2015-06-26T14:07:01Z

Adding support to hold comm name together with pids in 'struct thread_map'. It will be useful for --per-thread option to display task pid together with task name. Adding thread_map__read_comms function that reads/set comm string for the 'struct thread_map'. Getting the task name from /proc/$pid/comm.

tools: Remove bitops/hweight usage of bits in tools/perf

2015-01-16T20:49:29Z

We need to use lib/hweight.c for that, just like we do for lib/rbtree.c, so tools need to link hweight.o. For now do it directly, but we need to have a tools/lib/lk.a or .so that collects these goodies...
