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: Remove string.h, unistd.h and sys/stat.h from util.h

2017-04-24T16:43:33Z

Not needed in this header, added to the places that need FILE, putchar(), access() and a few other prototypes. Link: http://lkml.kernel.org/n/tip-xxtdsl6nsna82j7puwbdjqhs@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: 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

perf stat: Fix bug in handling events in error state

2017-04-13T13:40:36Z

(This is a patch has been sitting in the Intel CQM/CMT driver series for a while, despite not depend on it. Sending it now independently since the series is being discarded.) When an event is in error state, read() returns 0 instead of sizeof() buffer. In certain modes, such as interval printing, ignoring the 0 return value may cause bogus count deltas to be computed and thus invalid results printed. This patch fixes this problem by modifying read_counters() to mark the event as not scaled (scaled = -1) to force the printout routine to show .

perf stat: Refactor the code to strip csv output with ltrim()

2017-04-11T11:45:10Z

To strip csv output, use ltrim() instead of just while loop and isspace() at print_metric_{only}_csv().
