From: Jiri Olsa @ 2014-05-21 13:12 UTC (permalink / raw)
To: Ingo Molnar; +Cc: linux-kernel, Namhyung Kim, Jiri Olsa
From: Namhyung Kim <namhyung@kernel.org>
Until now the hpp and sort functions do similar jobs different ways.
Since the sort functions converted/wrapped to hpp formats it can do
the job in a uniform way.
The perf_hpp__sort_list has a list of hpp formats to sort entries and
the perf_hpp__list has a list of hpp formats to print output result.
To have a backward compatibility, it automatically adds 'overhead'
field in front of sort list. And then all of fields in sort list
added to the output list (if it's not already there).

From: Namhyung Kim <namhyung@kernel.org>
The callback was used by TUI for determining color of folded sign
using percent of first field/column. But it cannot be used anymore
since it now support dynamic reordering of output field.
So move the logic to the hist_browser__show_entry().

From: Namhyung Kim <namhyung@kernel.org>
The perf uses different default sort orders for different use-cases,
and this was scattered throughout the code. Add get_default_sort_
order() function to handle this and change initial value of sort_order
to NULL to distinguish it from user-given one.

So that it can be set properly prior to set up output fields. That
makes easy to handle/warn errors during the setup since it doesn't
need to be bothered with the GUI.

The -F/--fields option is to allow user setup output field in any
order. It can receive any sort keys and following (hpp) fields:
overhead, overhead_sys, overhead_us, sample and period
If guest profiling is enabled, overhead_guest_{sys,us} will be
available too.
The output fields also affect sort order unless you give -s/--sort
option. And any keys specified on -s option, will also be added to
the output field list automatically.

From: Namhyung Kim <namhyung@kernel.org>
Currently, what the sort_entry does is just identifying hist entries
so that they can be grouped properly. However, with -F option
support, it indeed needs to sort entries appropriately to be shown to
users. So add ->sort() member to do it.

From: Namhyung Kim <namhyung@kernel.org>
The hists__filter_entries() function is called when down arrow key is
pressed for navigating through the entries in TUI. It has a check for
filtering out entries that have very small overhead (under min_pcnt).
However it just assumed the entries are sorted by the overhead so when
it saw such a small overheaded entry, it just stopped navigating as an
optimization. But it's not true anymore due to new --fields and
--sort optoin behavior and this case users cannot go down to a next
entry if ther's an entry with small overhead in-between.

From: Namhyung Kim <namhyung@kernel.org>
The --fields option is to allow user setup output field in any order.
It can receive any sort keys and following (hpp) fields:
overhead, overhead_sys, overhead_us, sample and period
If guest profiling is enabled, overhead_guest_{sys,us} will be
available too.
More more information, please see previous patch "perf report:
Add -F option to specify output fields"

Some fields missed to set default column length so it broke align in
--stdio output. Add perf_hpp__reset_width() to set it to a sane
default value.
Note that this change will ignore -w/--column-widths option for now.

Now we moved to the perf_hpp_[_sort]_list so no need to keep the old
hist_entry__sort_list and sort__first_dimension. Also the
hist_entry__sort_snprintf() can be gone as hist_entry__snprintf()
provides the functionality.

This patch adds a fallback to cat for the pager. This is useful
on environments, such as Android, where less does not exist.
It is better to default to cat than to abort.

From: Michael Lentine <mlentine@google.com>
This patch automatically adjusts the path of MMAP records
associated with Android system libraries.
The Android system is organized with system libraries found in
/system/lib and user libraries in /data/app-lib. On the host system
(not running Android), system libraries can be found in the downloaded
NDK directory under ${NDK_ROOT}/platforms/${APP_PLATFORM}/arch-${ARCH}/usr/lib
and the user libraries are installed under libs/${APP_ABI} within
the apk build directory. This patch makes running the reporting
tools possible on the host system using the libraries from the NDK.
