perf tools: Add automatic remapping of Android libraries · eca81836

由 Michael Lentine 提交于 5月 20, 2014

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.

perf tools: Add cat as fallback pager · 21cfc5e1

由 Michael Lentine 提交于 5月 20, 2014

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.

perf tools: Get rid of obsolete hist_entry__sort_list · cfaa154b

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()

perf hists: Reset width of output fields with header length · 678a500d

由 Namhyung Kim 提交于 3月 20, 2014

Some fields missed to set default column length so it broke align in

default value.

Note that this change will ignore -w/--column-widths option for now.

perf report/tui: Fix a bug when --fields/sort is given · c0f1527b

由 Namhyung Kim 提交于 4月 16, 2014

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.

perf tools: Add ->sort() member to struct sort_entry · 202e7a6d

由 Namhyung Kim 提交于 3月 04, 2014

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.

perf report: Add -F option to specify output fields · a7d945bc

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.
