perf report: Enable group view with hierarchy

2016-09-13T19:43:41+00:00

Now that all the missing pieces are implemented, let's enable it.  An
example output below:

  $ perf record -e '{cycles,instructions}' make
  $ perf report --hierarchy --stdio
  ...

perf annotate: Initialize the priv are in symbol__new()

2016-08-30T13:56:34+00:00

We need to initializa some fields (right now just a mutex) when we
allocate the per symbol annotation struct, so do it at the symbol
constructor instead of (ab)using the filter mechanism for that.

This way we remove one of the few cases we have for that symbol filter,
which will eventually led to removing it.

perf report: Allow configuring the default sort order in ~/.perfconfig

2016-08-23T18:37:33+00:00

Allows changing the default sort order from "comm,dso,symbol" to some
other default, for instance "sym,dso" may be more fitting for kernel
developers.

perf report: Introduce --stdio-color to setup the color output mode selection

2016-07-12T03:00:39+00:00

'perf report --stdio' will colorize entries with most hits and possibly
some other aspects of its output, but those colors gets suppressed if we
redirect the output to a non-tty, allow keeping the colors by adding a
new option, --stdio-color, now this use case will also output escape
sequences for colors:

  $ perf annotate --stdio-color | more

perf evlist: Rename for_each() macros to for_each_entry()

2016-06-23T14:26:15+00:00

To match the semantics for list.h in the kernel, that are used to
implement those macros.

perf config: Move config declarations from util/cache.h to util/config.h

2016-06-23T11:51:41+00:00

Lately util/config.h has been added but util/cache.h has declarations of
functions and a global variable for config features.

To manage codes about configuration at one spot, move them to
util/config.h and let source files that need config features include
config.h And if the source files that included previous cache.h need
only config.h, remove including cache.h.

perf stdio: Add use_callchain parameter to hists__fprintf

2016-06-15T13:48:02+00:00

It will be convenient in following patches to display hists entries
without callchains even if they are defined.

perf tools: Set buildid dir under symfs when --symfs is provided

2016-05-20T14:43:58+00:00

This patch moves the reference of buildid dir to 'symfs/.debug' and
skips the local buildid dir when '--symfs' is given, so that every
single file opened by perf is relative to symfs directory now.

perf tools: Fix usage of max_stack sysctl

2016-05-20T14:43:56+00:00

We cannot limit processing stacks from the current value of the sysctl,
as we may be processing perf.data files, possibly from other machines.

Instead use the old PERF_MAX_STACK_DEPTH, the sysctl default, that can
be overriden using --max-stack or equivalent.

perf hists: Move sort__has_parent into struct perf_hpp_list

2016-05-06T00:03:59+00:00

Now we have sort dimensions private for struct hists, we need to make
dimension booleans hists specific as well.

Moving sort__has_parent into struct perf_hpp_list.
