2013-09-11perf tools: Add attr->mmap2 supportStephane Eranian
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.

Before: perf trace -i perf.data Segmentation fault (core dumped) # After: # perf trace -i perf.data Data file does not have raw_syscalls:sys_enter events # When there are no tracepoints in a perf.data file the struct pevent that contains the list of tracepoints that will be used to lookup the tracepoint id by name will not be populated, causing a NULL deref. And we don't need to do all that dance to look at pevents for an entry with a slighly different name to then lookup the tracepoint by its id on the evlist, just use the perf_evlist__find_tracepoint_by_name() routine, that will find the tracepoint, if present.

2013-09-05perf session: Separate progress bar update when processing eventsJiri Olsa
Currently when processing events in the __perf_session__process_events function we update a progress bar based on the file_size. During the same processing we update the progress bar from within flush_sample_queue which is based on number of samples count. Having 2 different based updates is causing the progress bar to jump heavily back and forth giving not much usefull info. Fixing this by keeping only __perf_session__process_events based progress bar update. And turning on flush_sample_queue progress bar update only for final flushing. This reduces the number of time the progress bar update function is called and it significantly reduces the loading time for TUI, where the progress bar update takes quite a lot of time.

2013-09-05perf evlist: Fix parsing with no sample_id_all bit setAdrian Hunter
The perf_evlist__event2evsel() is changed to handle non-sample events (such as mmap events) that have no id sample appended i.e. when sample_id_all is not set.

2013-08-26perf trace: Allow overiding the formatting of syscall fieldsArnaldo Carvalho de Melo
The mmap syscalls, for instance, don't have the FORMAT_IS_POINTER for its pointer arguments, override it. This also paves the way for more specialized argument beautifiers, like for mmap's prot and flags arguments.

event_format->flags has a FIELD_IS_POINTER, but it is not set for the sys_exit 'ret' field in syscalls like mmap, so we need a way to ask for hex printing for pointer returns and keep things like 'read' returns printing in decimal.
