perf scripting: No need to pass thread twice to the scripting callbacks

2015-04-02T16:18:41+00:00

It is already in the addr_location, so remove the redundant 'thread' parameter from the callback signatures.

perf tools: Introduce event_format__fprintf method

2015-02-06T10:46:37+00:00

The existing one, event_format__print() uses stdout unconditionally, and 'perf trace' needs to use it to format into a file that may have been set by the user, i.e. 'trace -o file.output'.

perf scripting: Add 'flush' callback to scripting API

2014-08-22T16:12:11+00:00

In order to defer some output via the scripting API, there needs to be a callback after session processing but before the session is deleted.

perf symbols: Add 'machine' member to struct addr_location

2013-12-19T20:38:27+00:00

The addr_location struct should fully qualify an address, and to do that it should have in it the machine where the thread was found. Thus all functions that receive an addr_location now don't need to also receive a 'machine', those functions just need to access al->machine instead, just like it does with the other parts of an address location: al->thread, al->map, etc. Cc: Adrian Hunter Cc: David Ahern Cc: Frederic Weisbecker Cc: Jiri Olsa Cc: Mike Galbraith Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/n/tip-o51iiee7vyq4r3k362uvuylg@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Add trace-event global object for tracepoint interface

2013-12-04T18:21:25+00:00

In order to get the proper plugins processing we need to use full trace-event interface when creating tracepoint events. So far we were using shortcut to get the parsed format. Moving current 'event_format__new' function into trace-event object as 'trace_event__tp_format'. This function uses properly initialized global trace-event object, ensuring proper plugins processing.

perf tools: Add trace-event object

2013-12-04T18:20:52+00:00

Add trace-event object to keep together 'struct pevent' object with its loaded plugins with following interface: int trace_event__init(struct trace_event *t); - Initalizes 'struct pevent' object and loads plugins for it void trace_event__cleanup(struct trace_event *t); - Cleanups both 'struct pevent' and plugins Signed-off-by: Jiri Olsa Cc: Corey Ashford Cc: David Ahern Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Steven Rostedt Link: http://lkml.kernel.org/r/1386076182-14484-10-git-send-email-jolsa@redhat.com Signed-off-by: Arnaldo Carvalho de Melo

perf script: Fix named threads support

2013-07-22T14:55:53+00:00

Commit 73994dc broke named thread support in perf-script. The thread struct in al is the main thread for a multithreaded process. The thread struct used for analysis (e.g., dumping events) should be the specific thread for the sample.

perf util: Remove unused enum and macro in trace-event.h

2013-07-12T16:52:33+00:00

They're internals of ftrace ring-buffer and not used in perf code directly. As it now resides on libtraceevent/kbuffer.h, just get rid of them.
