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.

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.

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: NAdrian Hunter <adrian.hunter@intel.com> Acked-by: NDavid Ahern <dsahern@gmail.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@kernel.org> 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 <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/r/1377591794-30553-2-git-send-email-adrian.hunter@intel.comSigned-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>

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.

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.

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

We already lookup the associated event_format when reading the perf.data header, so that we can cache the tracepoint name in evsel->name, so do it a little further and save the event_format itself, so that we can avoid relookups in tools that need to access it. Change the tools to take the most obvious advantage, when they were using pevent_find_event directly. More work is needed for further removing the need of a pointer to pevent, such as when asking for event field values ("common_pid" and the other common fields and per event_format fields). This is something that was planned but only got actually done when Andrey Wagin needed to do this lookup at perf_tool->sample() time, when we don't have access to pevent (session->pevent) to use with pevent_find_event().

The pevent thing is per perf.data file, so I made it stop being static and become a perf_session member, so tools processing perf.data files use perf_session and _there_ we read the trace events description into session->pevent and then change everywhere to stop using that single global pevent variable and use the per session one. Note that it _doesn't_ fall backs to trace__event_id, as we're not interested at all in what is present in the /sys/kernel/debug/tracing/events in the workstation doing the analysis, just in what is in the perf.data file. This patch also introduces perf_session__set_tracepoints_handlers that is the perf perf.data/session way to associate handlers to tracepoint events by resolving their IDs using the events descriptions stored in a perf.data file. Make 'perf sched' use it.

The event parsing code in perf was originally copied from trace-cmd but never was kept up-to-date with the changes that was done there. The trace-cmd libtraceevent.a code is much more mature than what is currently in perf. This updates the code to use wrappers to handle the calls to the new event parsing code. The new code requires a handle to be pass around, which removes the global event variables and allows more than one event structure to be read from different files (and different machines). But perf still has the old global events and the code throughout perf does not yet have a nice way to pass around a handle. A global 'pevent' has been made for perf and the old calls have been created as wrappers to the new event parsing code that uses the global pevent. With this change, perf can later incorporate the pevent handle into the perf structures and allow more than one file to be read and compared, that contains different events.

The default input file for perf report is not handled the same way as perf record does it for its output file. This leads to unexpected behavior of perf report, etc. E.g.: # perf record -a -e cpu-cycles sleep 2 | perf report | cat failed to open perf.data: No such file or directory (try 'perf record' first) While perf record writes to a fifo, perf report expects perf.data to be read. This patch changes this to accept fifos as input file. Applies to the following commands: perf annotate perf buildid-list perf evlist perf kmem perf lock perf report perf sched perf script perf timechart Also fixes char const* -> const char* type declaration for filename strings. v2: * Prevent potential null pointer access to input_name in builtin-report.c.
