perf script: Set up output options for in-stream attributes

2013-11-04T15:19:26Z

Attributes (struct perf_event_attr) are recorded separately in the perf.data file. perf script uses them to set up output options. However attributes can also be in the event stream, for example when the input is a pipe (i.e. live mode). This patch makes perf script process in-stream attributes in the same way as on-file attributes. Here is an example: Before this patch: $ perf record uname | perf script Linux [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.015 MB (null) (~655 samples) ] :4220 4220 [-01] 2933367.838906: cycles: :4220 4220 [-01] 2933367.838910: cycles: :4220 4220 [-01] 2933367.838912: cycles: :4220 4220 [-01] 2933367.838914: cycles: :4220 4220 [-01] 2933367.838916: cycles: :4220 4220 [-01] 2933367.838918: cycles: uname 4220 [-01] 2933367.838938: cycles: uname 4220 [-01] 2933367.839207: cycles: After this patch: $ perf record uname | perf script Linux [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.015 MB (null) (~655 samples) ] :4582 4582 2933425.707724: cycles: ffffffff81043ffa native_write_msr_safe ([kernel.kallsyms]) :4582 4582 2933425.707728: cycles: ffffffff81043ffa native_write_msr_safe ([kernel.kallsyms]) :4582 4582 2933425.707730: cycles: ffffffff81043ffa native_write_msr_safe ([kernel.kallsyms]) :4582 4582 2933425.707732: cycles: ffffffff81043ffa native_write_msr_safe ([kernel.kallsyms]) :4582 4582 2933425.707734: cycles: ffffffff81043ffa native_write_msr_safe ([kernel.kallsyms]) :4582 4582 2933425.707736: cycles: ffffffff81309a24 memcpy ([kernel.kallsyms]) uname 4582 2933425.707760: cycles: ffffffff8109c1c7 enqueue_task_fair ([kernel.kallsyms]) uname 4582 2933425.707978: cycles: ffffffff81308457 clear_page_c ([kernel.kallsyms]) Signed-off-by: Adrian Hunter Cc: David Ahern Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Jiri Olsa Cc: Mike Galbraith Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/r/1383313899-15987-3-git-send-email-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Use an accessor to read thread comm

2013-11-04T14:50:28Z

As the thread comm is going to be implemented by way of a more complicated data structure than just a pointer to a string from the thread struct, convert the readers of comm to use an accessor instead of accessing it directly. The accessor will be later overriden to support an enhanced comm implementation.

perf tools: Add data object to handle perf data file

2013-10-21T20:33:24Z

This patch is adding 'struct perf_data_file' object as a placeholder for all attributes regarding perf.data file handling. Changing perf_session__new to take it as an argument. The rest of the functionality will be added later to keep this change simple enough, because all the places using perf_session are changed now.

perf script: Print addr by default for BTS

The addr field is not displayed by default for hardware events, however for branch events it is the target of the branch so for BTS display it by default if it was recorded.

When processing big files we were not checking if session_done was set by the SIGINT signal handler, for instance in 'perf report'. Fix it.

perf tools: Add attr->mmap2 support

2013-09-11T13:09:32Z

This patch adds support for the new PERF_RECORD_MMAP2 record type exposed by the kernel. This is an extended PERF_RECORD_MMAP record. It adds for each file-backed mapping the device major, minor number and the inode number and generation. This triplet uniquely identifies the source of a file-backed mapping. It can be used to detect identical virtual mappings between processes, for instance. The patch will prefer MMAP2 over MMAP.

perf tools: Remove references to struct ip_event

2013-08-29T18:29:28Z

The ip_event struct assumes fixed positions for ip, pid and tid. That is no longer true with the addition of PERF_SAMPLE_IDENTIFIER. The information is anyway in struct sample, so use that instead.

perf tools: change machine__findnew_thread() to set thread pid

2013-08-29T14:51:31Z

Add a new parameter for 'pid' to machine__findnew_thread(). Change callers to pass 'pid' when it is known. Note that callers sometimes want to find the main thread which has the memory maps. The main thread has tid == pid so the usage in that case is: machine__findnew_thread(machine, pid, pid) whereas the usage to find the specific thread is: machine__findnew_thread(machine, pid, tid) Signed-off-by: Adrian Hunter Acked-by: David Ahern Cc: David Ahern Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Jiri Olsa Cc: Mike Galbraith Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/r/1377591794-30553-2-git-send-email-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo
