perf script: Fix named threads support

2013-07-22T14:55:53Z

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

2013-07-12T16:52:33Z

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.

perf util: Get rid of unused header_page_* variables

2013-07-12T16:52:26Z

They're not used anywhere and same information is kept in a pevent already. So let's get rid of them.

perf tools: Use default include path notation for libtraceevent headers

2013-07-12T16:45:54Z

Header files of libtraceevent or no longer local headers. Thus, use default path notation for them. Also removing extra traceevent include path and instead handle this similar to liblk.

perf tools: Support for DWARF CFI unwinding on post processing

2012-08-11T18:06:56Z

This brings the support for DWARF cfi unwinding on perf post processing. Call frame informations are retrieved and then passed to libunwind that requests memory and register content from the applications. Adding unwind object to handle the user stack backtrace based on the user register values and user stack dump. The unwind object access the libunwind via remote interface and provides to it all the necessary data to unwind the stack. The unwind interface provides following function: unwind__get_entries And callback (specified in above function) to retrieve the backtrace entries: typedef int (*unwind_entry_cb_t)(struct unwind_entry *entry, void *arg); Signed-off-by: Jiri Olsa Original-patch-by: Frederic Weisbecker Cc: "Frank Ch.

perf script: Replace "struct thread" with "struct addr_location" as a parameter for "process_event()"

2012-08-08T15:46:40Z

Both perl and python script start processing events other than trace points, and it's useful to pass the resolved symbol and the dso info to the event handler in script for better analysis and statistics. Struct thread is already a member of struct addr_location, using addr_location will keep the thread info, while providing additional symbol and dso info if exist, so that the script itself doesn't need to bother to do the symbol resolving and dso searching work.

perf script: Stop using pevent directly

2012-08-08T02:50:21Z

We can get all that is needed using just event_format, that is available via evsel->tp_format now.
