      perf hists: Do column alignment on the format iterator · 89fee709
      由 Arnaldo Carvalho de Melo 提交于 
      We were doing column alignment in the format function for each cell,
returning a string padded with spaces so that when the next column is
printed the cursor is at its column alignment.

This ends up needlessly printing trailing spaces, do it at the format
iterator, that is where we know if it is needed, i.e. if there is more
columns to be printed.

This eliminates the need for triming lines when doing a dump using 'P'
in the TUI browser and also produces far saner results with things like
piping 'perf report' to 'less'.

Right now only the formatters for sym->name and the 'locked' column
(perf mem report), that are the ones that end up at the end of lines
in the default 'perf report', 'perf top' and 'perf mem report' tools,
the others will be done in a subsequent patch.

In the end the 'width' parameter for the formatters now mean, in
'printf' terms, the 'precision', where before it was the field 'width'.

      perf tools: Skip dynamic fields not defined for current event · 361459f1
      由 Namhyung Kim 提交于 
      When there are multiple events, each dynamic sort key is defined just
for one event.  In this case other events will always show "N/A" for
those fields.  But they are meaningless and consume precious screen
width.

Let's skip those undefined dynamic fields.

  $ perf record -e kmem:kmalloc,kmem:kfree -a sleep 1

  $ perf report -s 'comm,kmalloc.*' --stdio

      perf tools: Allocate thread map_groups's dynamically · 93d5731d
      由 Arnaldo Carvalho de Melo 提交于 
      Moving towards sharing map groups within a process threads.

Because of this we need the map groups to be dynamically allocated. No
other functional change is intended in here.

Based on a patch by Jiri Olsa, but this time _just_ making the
conversion from statically allocating thread->mg to turning it into a
pointer and instead of initializing it at thread's constructor,
introduce a constructor/destructor for the map_groups class and
call at thread creation time.

Later we will introduce the get/put methods when we move to sharing
those map_groups, when the get/put refcounting semantics will be needed.
