lib, traceevent: add PRINT_HEX_STR variant

2017-01-25T18:17:47+00:00

Add support for the __print_hex_str() macro that was added for tracing, so that user space tools such as perf can understand it as well. Signed-off-by: Daniel Borkmann Cc: Steven Rostedt Cc: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

tools lib traceevent: Add retrieval of preempt count and latency flags

2016-11-23T13:44:03+00:00

Add a way to retrieve the preempt count as well as the latency flags from a pevent_record. int pevent_data_preempt_count(pevent, record); returns the preempt count of a record. int pevent_data_flags(pevent, record); returns the latency flags for a record.

tools lib traceevent: Use USECS_PER_SEC instead of hardcoded number

2016-11-23T13:44:02+00:00

Instead of using 1000000, use the define in time64.h instead. Also remove the the duplicate defines for NSECS_PER_SEC.

tools lib traceevent: Split pevent_print_event() into specific functionality functions

2016-02-29T14:35:21+00:00

Currently there's a single function that is used to display a record's data in human readable format. That's pevent_print_event(). Unfortunately, this gives little room for adding other output within the line without updating that function call. I've decided to split that function into 3 parts. pevent_print_event_task() which prints the task comm, pid and the CPU pevent_print_event_time() which outputs the record's timestamp pevent_print_event_data() which outputs the rest of the event data. pevent_print_event() now simply calls these three functions. To save time from doing the search for event from the record's type, I created a new helper function called pevent_find_event_by_record(), which returns the record's event, and this event has to be passed to the above functions.

tools lib traceevent: Factor out and export print_event_field[s]()

2016-01-06T23:11:11+00:00

The print_event_field() and print_event_fields() functions print basic information of a given field or event without the print format. They'll be used by dynamic sort keys later. Committer note: Rename it to pevent_print_field[s]() to get proper namespacing, as discussed with Steven Rostedt.

tools lib traceevent: Support function __get_dynamic_array_len

2015-09-02T19:30:46+00:00

Support helper function __get_dynamic_array_len() in libtraceevent, this function is used accompany with __print_array() or __print_hex(), but currently it is not an available function in the function list of process_function(). The total allocated length of the dynamic array is embedded in the top half of __data_loc_##item field.

tools lib traceevent: Allow setting an alternative symbol resolver

2015-07-24T01:01:26+00:00

The perf tools have a symbol resolver that includes solving kernel symbols using either kallsyms or ELF symtabs, and it also is using libtraceevent to format the trace events fields, including via subsystem specific plugins, like the "timer" one. To solve fields like "timer:hrtimer_start"'s "function", libtraceevent needs a way to map from its value to a function name and addr. This patch provides a way for tools that already have symbol resolving facilities to ask libtraceevent to use it when needing to resolve kernel symbols.
