      "message": "perf inject: Fix broken perf inject -b\n\nperf inject -b was broken. It would not inject any build_id into the\nstream. Furthermore, it would strip samples from the stream.\n\nThe reason was a missing initialization of the event attribute\nstructure. The perf_tool.tool.attr() callback was pointing to a simple\nrepipe. But there was no initialization of the internal data structures\nto keep track of events and event ids. That later caused event id\nlookups to fail, and sample would get removed.\n\nThe patch simply adds back the call to perf_event__process_attr() to\ninitialize the evlist structure and now build_ids are again injected.\n\nSigned-off-by: Stephane Eranian \u003ceranian@google.com\u003e\nCc: David Ahern \u003cdsahern@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nLink: http://lkml.kernel.org/r/1337081295-10303-2-git-send-email-eranian@google.com\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n"

      "message": "perf: add perf-inject builtin\n\nCurrently, perf \u0027live mode\u0027 writes build-ids at the end of the\nsession, which isn\u0027t actually useful for processing live mode events.\n\nWhat would be better would be to have the build-ids sent before any of\nthe samples that reference them, which can be done by processing the\nevent stream and retrieving the build-ids on the first hit.  Doing\nthat in perf-record itself, however, is off-limits.\n\nThis patch introduces perf-inject, which does the same job while\nleaving perf-record untouched.  Normal mode perf still records the\nbuild-ids at the end of the session as it should, but for live mode,\nperf-inject can be injected in between the record and report steps\ne.g.:\n\nperf record -o - ./hackbench 10 | perf inject -v -b | perf report -v -i -\n\nperf-inject reads a perf-record event stream and repipes it to stdout.\nAt any point the processing code can inject other events into the\nevent stream - in this case build-ids (-b option) are read and\ninjected as needed into the event stream.\n\nBuild-ids are just the first user of perf-inject - potentially\nanything that needs userspace processing to augment the trace stream\nwith additional information could make use of this facility.\n\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Frédéric Weisbecker \u003cfweisbec@gmail.com\u003e\nLKML-Reference: \u003c1272696080-16435-3-git-send-email-tzanussi@gmail.com\u003e\nSigned-off-by: Tom Zanussi \u003ctzanussi@gmail.com\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n"
