perf trace: Add mmap alias for s390

2017-06-01T13:13:21Z

The s390 architecture maps sys_mmap (nr 90) into sys_old_mmap. For this reason perf trace can't find the proper syscall event to get args format from and displays it wrongly as 'continued'. To fix that fill the "alias" field with "old_mmap" for trace's mmap record to get the correct translation.

perf tools: Move event prototypes from util.h to event.h

2017-04-25T18:30:47Z

More needs to be done to have the actual functions and variables in a smaller .c file that can then be included in the python binding, avoiding dragging more stuff into it. Link: http://lkml.kernel.org/n/tip-uecxz7cqkssouj7tlxrkqpl4@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Remove poll.h and wait.h from util.h

2017-04-24T16:43:34Z

Not needed in this header, added to the places that need poll(), wait() and a few other prototypes. Link: http://lkml.kernel.org/n/tip-i39c7b6xmo1vwd9wxp6fmkl0@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Add signal.h to places using its definitions

2017-04-20T16:22:43Z

And remove it from util.h, disentangling it a bit more. Link: http://lkml.kernel.org/n/tip-2zg9s5nx90yde64j3g4z2uhk@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Move path related functions to util/path.h

Disentangling util.h header mess a bit more. Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Namhyung Kim Cc: Wang Nan Link: http://lkml.kernel.org/n/tip-aj6je8ly377i4upedmjzdsq6@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Include errno.h where needed

2017-04-19T16:01:51Z

Removing it from util.h, part of an effort to disentangle the includes hell, that makes changes to util.h or something included by it to cause a complete rebuild of the tools.

perf tools: Move extra string util functions to util/string2.h

2017-04-19T16:01:51Z

Moving them from util.h, where they don't belong. Since libc already have string.h, name it slightly differently, as string2.h.

More stuff that came from git, out of the hodge-podge that is util.h Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Namhyung Kim Cc: Wang Nan Link: http://lkml.kernel.org/n/tip-e3lana4gctz3ub4hn4y29hkw@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo
