[GIT PULL 00/24] perf/core improvements and fixes

Show all headers | View raw

Hi Ingo,

	Please consider pulling,

Test results, with a new target: cross-compiling to Android ARM API 24 (NDK r12b),
for all except android-ndk:r12b now objtool is tested too, in adition to tools/perf.

  [root@jouet ~]# dm

oops, the mageia image din't got rebuilt, will fix that, pretty good coverage
even so :-)

  objtool: Initialize variable to silence old compiler (2016-07-15 17:32:52 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- Allow reading from a backward ring buffer (one setup via sys_perf_event_open
  with perf_event_attr.write_backward = 1) (Wang Nan)

Infrastructure:

- Fix the build on Android NDK r12b (initially just for arm), that is now port
  of my perf-build container collection and will get tested prior to sending
  patches upstream (Arnaldo Carvalho de Melo)

- Add correct header for ipv6 defini

- Fix bitsperlong.h fallout (Arnaldo Carvalho de Melo, Peter Zijlstra)

- Use base 0 (auto) in filename__read_ull, so that we can handle hex values too (Jiri Olsa)

Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

----------------------------------------------------------------
