perf report: Accept fifos as input file

2011-12-23T19:01:03Z

The default input file for perf report is not handled the same way as perf record does it for its output file. This leads to unexpected behavior of perf report, etc. E.g.: # perf record -a -e cpu-cycles sleep 2 | perf report | cat failed to open perf.data: No such file or directory (try 'perf record' first) While perf record writes to a fifo, perf report expects perf.data to be read. This patch changes this to accept fifos as input file. Applies to the following commands: perf annotate perf buildid-list perf evlist perf kmem perf lock perf report perf sched perf script perf timechart Also fixes char const* -> const char* type declaration for filename strings. v2: * Prevent potential null pointer access to input_name in builtin-report.c. Needed due to removal of patch "perf report: Setup browser if stdout is a pipe" Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/r/1323248577-11268-5-git-send-email-robert.richter@amd.com Signed-off-by: Robert Richter Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Rename perf_event_ops to perf_tool

2011-11-28T12:39:28Z

To better reflect that it became the base class for all tools, that must be in each tool struct and where common stuff will be put.

perf tools: Resolve machine earlier and pass it to perf_event_ops

2011-11-28T12:39:12Z

Reducing the exposure of perf_session further, so that we can use the classes in cases where no perf.data file is created.

perf tools: Pass tool context in the the perf_event_ops functions

2011-11-28T12:38:56Z

So that we don't need to have that many globals. Next steps will remove the 'session' pointer, that in most cases is not needed. Then we can rename perf_event_ops to 'perf_tool' that better describes this class hierarchy.

perf lock: Dropping unsupported ':r' modifier

2011-08-08T12:41:35Z

Looks to me like the :r modifier is not supported anymore, so remove it from the list of events. Without this fix 'perf lock record' doesn't work.

perf session: Pass evsel in event_ops->sample()

2011-03-23T22:28:58Z

Resolving the sample->id to an evsel since the most advanced tools, report and annotate, and the others will too when they evolve to properly support multi-event perf.data files. Good also because it does an extra validation, checking that the ID is valid when present. When that is not the case, the overhead is just a branch + function call (perf_evlist__id2evsel).

perf lock: Fix sorting by wait_min

2011-03-16T12:05:58Z

If lock was uncontended, wait_time_min == ULLONG_MAX, so we need to handle this case differently to show high wait times first Acked-by: Hitoshi Mitake Cc: Hitoshi Mitake Cc: Ingo Molnar Cc: Paul Mackerras Cc: Peter Zijlstra LKML-Reference: <20110222174715.GC9687@joi.lan> Signed-off-by: Marcin Slusarz Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Kill event_t typedef, use 'union perf_event' instead

2011-01-29T18:25:37Z

And move the event_t methods to the perf_event__ too. No code changes, just namespace consistency. Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Mike Galbraith Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian Cc: Tom Zanussi LKML-Reference: Signed-off-by: Arnaldo Carvalho de Melo
