perf tools: Use just forward declarations for struct thread where possible

2017-04-24T16:43:35Z

Removing various instances of unnecessary includes, reducing the maze of header dependencies. Link: http://lkml.kernel.org/n/tip-hwu6eyuok9pc57alookyzmsf@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: Remove unused 'prefix' from builtin functions

2017-03-27T14:58:09Z

We got it from the git sources but never used it for anything, with the place where this would be somehow used remaining: static int run_builtin(struct cmd_struct *p, int argc, const char **argv) { prefix = NULL; if (p->option & RUN_SETUP) prefix = NULL; /* setup_perf_directory(); */ Ditch it.

perf tools: Add PERF_RECORD_NAMESPACES to include namespaces related info

2017-03-14T14:38:23Z

Introduce a new option to record PERF_RECORD_NAMESPACES events emitted by the kernel when fork, clone, setns or unshare are invoked. And update perf-record documentation with the new option to record namespace events. Committer notes: Combined it with a later patch to allow printing it via 'perf report -D' and be able to test the feature introduced in this patch. Had to move here also perf_ns__name(), that was introduced in another later patch. Also used PRIu64 and PRIx64 to fix the build in some enfironments wrt: util/event.c:1129:39: error: format '%lx' expects argument of type 'long unsigned int', but argument 6 has type 'long long unsigned int' [-Werror=format=] ret += fprintf(fp, "%u/%s: %lu/0x%lx%s", idx ^ Testing it: # perf record --namespaces -a ^C[ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 1.083 MB perf.data (423 samples) ] # # perf report -D 3 2028902078892 0x115140 [0xa0]: PERF_RECORD_NAMESPACES 14783/14783 - nr_namespaces: 7 [0/net: 3/0xf0000081, 1/uts: 3/0xeffffffe, 2/ipc: 3/0xefffffff, 3/pid: 3/0xeffffffc, 4/user: 3/0xeffffffd, 5/mnt: 3/0xf0000000, 6/cgroup: 3/0xeffffffb] 0x1151e0 [0x30]: event: 9 . . ... raw event: size 48 bytes . 0000: 09 00 00 00 02 00 30 00 c4 71 82 68 0c 7f 00 00 ......0..q.h.... . 0010: a9 39 00 00 a9 39 00 00 94 28 fe 63 d8 01 00 00 .9...9...(.c.... . 0020: 03 00 00 00 00 00 00 00 ce c4 02 00 00 00 00 00 ................

It now can have negative value to suppress the message entirely. So it needs to check it being positive.

perf tools mem: Fix -t store option for record command

2016-08-12T17:39:48Z

Michael reported 'perf mem -t store record' being broken. The reason is latest rework of this area: commit acbe613e0c03 ("perf tools: Add monitored events array") We don't mark perf_mem_events store record when -t store option is specified.
