perf tools: Convert critical messages to ui__error()

2012-05-29T14:53:42+00:00

There were places where use ui__warning (or even fprintf) to show critical messages. This patch converts them to ui__error so that the front-end code can implement appropriate behavior.

perf annotate: Get rid of field_sep check

2012-01-08T15:29:34+00:00

The 'field_sep' variable is not set anywhere. Just remove the conditional. Cc: Ingo Molnar Cc: Paul Mackerras Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1325957132-10600-7-git-send-email-namhyung@gmail.com Signed-off-by: Namhyung Kim Signed-off-by: Arnaldo Carvalho de Melo

perf annotate: Fix usage string

2012-01-08T15:28:48+00:00

The annotate command doesn't take non-option arguments. In fact, it can take last argument as a symbol filter though, but that's a special case and, IMHO, it should be discouraged in favor of the -s option.

perf report: Accept fifos as input file

2011-12-23T19:01:03+00:00

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: make -C consistent across commands (for cpu list arg)

2011-11-28T13:45:53+00:00

Currently the meaning of -C varies by perf command: for perf-top, perf-stat, perf-record it means cpu list. For perf-report it means comm list. Then perf-annotate, perf-report and perf-script use -c for cpu list. Fix annotate, report and script to use -C for cpu list to be consistent with top, stat and record. This means report needs to use -c for comm list which does introduce a backward compatibility change. v1 -> v2 - update perf-script.txt too Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1321209008-7004-1-git-send-email-dsahern@gmail.com Signed-off-by: David Ahern Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Rename perf_event_ops to perf_tool

2011-11-28T12:39:28+00:00

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

2011-11-28T12:39:12+00:00

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

2011-11-28T12:38:56+00:00

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 annotate: Group options in a struct

2011-11-28T12:38:40+00:00

Paving the way to remove these globals when we change the perf_event_ops to receive as a first parameter a pointer to a perf_event_ops that will then provide access to perf_annotate via container_of.

perf symbols: Add nr_events to symbol_conf

2011-11-28T12:37:11+00:00

Since symbol__alloc_hists need it, to avoid passing it around in many functions have it in the symbol_conf struct.
