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 <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/n/tip-o51iiee7vyq4r3k362uvuylg@git.kernel.orgSigned-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>

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: NAdrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Namhyung Kim <namhyung@gmail.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/r/1383313899-15987-3-git-send-email-adrian.hunter@intel.comSigned-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>

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.

In order to use kernel maps to read object code, those maps must be adjusted to map to the dso file offset. Because lazy-initialization is used, that is not done until symbols are loaded. However the maps are first used by thread__find_addr_map() before symbols are loaded. So this patch changes thread__find_addr() to "load" kernel maps before using them.

As suggested by Arnaldo, many scripts have their own usages and need capture specific events or tracepoints, so only those scripts whose target events match the events in current perf data file should be listed in the script browser menu. This patch will add the event match checking, by opening "xxx-record" script to cherry pick out all events name and comparing them with those inside the perf data file.

Currently many perf commands annotate/evlist/report/script/lock etc all support "-i" option to chose a specific perf data, and all of them create a local "input_name" to save the file name for that perf data. Since most of these commands need it, we can add a global variable for it, also it can some other benefits: 1. When calling script browser inside hists/annotation browser, it needs to know the perf data file name to run that script. 2. For further feature like runtime switching to another perf data file, this variable can also help.

When we were processing a PERF_RECORD_EXIT event we first used machine__findnew_thread for both the thread exiting and for its parent, only to use just the thread struct associated with the one exiting, and to just delete it. If it existed, i.e. not created at this very moment in machine__findnew_thread, it will be moved to the machine->dead_threads linked list, because we may have hist_entries pointing to it, but if it was created just do be deleted, it will just sit there with no references at all. Use the new machine__find_thread() method so that if it is not there, we don't create it. As a bonus the parent thread will also not be created at this point. Create process_fork() and process_exit() helpers to use this and make the builtins use it instead of the generic process_task(), ditched by this patch.

perf defines both __used and __unused variables to use for marking unused variables. The variable __used is defined to __attribute__((__unused__)), which contradicts the kernel definition to __attribute__((__used__)) for new gcc versions. On Android, __used is also defined in system headers and this leads to warnings like: warning: '__used__' attribute ignored __unused is not defined in the kernel and is not a standard definition. If __unused is included everywhere instead of __used, this leads to conflicts with glibc headers, since glibc has a variables with this name in its headers. The best approach is to use __maybe_unused, the definition used in the kernel for __attribute__((unused)). In this way there is only one definition in perf sources (instead of 2 definitions that point to the same thing: __used and __unused) and it works on both Linux and Android. This patch simply replaces all instances of __used and __unused with __maybe_unused.

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: NJiri Olsa <jolsa@redhat.com> Original-patch-by: NFrederic Weisbecker <fweisbec@gmail.com> Cc: "Frank Ch.
