f7e5410920 perf ui browser: Clean lines inside of the input window 
As Arnaldo pointed out, it should be cleared to prevent the window from
displaying overlapped strings on the region.

938a23ae7f perf ui browser: Add 's' key to filter by symbol name 
Now user can enter symbol name interested via ui_browser__input_window,
and perf can process it using hists__filter_by_symbol(). Giving empty
symbol (by pressing 's' followed by ENTER) will disable the filtering.

5090c6aea8 perf tools: Do not disable members of group event 
When event group is enabled for forked task (i.e. no target task/cpu
was specified) all events were disabled and marked ->enable_on_exec.
However they wouldn't be counted at all since only group leader will
be enabled on exec actually.

In contrast to perf stat, perf record doesn't have a real problem
as it enables all the event before proceeding. But it needs to be
fixed anyway IMHO.

5f537a2659 perf tools: Add support to specify pmu style event 
Added new event rule to the event definition grammar:

event_def: event_pmu |
           ...
event_pmu: PE_NAME '/' event_config '/'

Using this rule, event could be now specified like:
  cpu/config=1,config1=2,config2=3/u

where pmu name 'cpu' is looked up via following path:
  ${sysfs_mount}/bus/event_source/devices/${pmu}

and config options are bound to the pmu's format definiton:
  ${sysfs_mount}/bus/event_source/devices/${pmu}/format

The hardcoded config options still stays and have precedence
over any format field defined with same name.

cd82a32e99 perf tools: Add perf pmu object to access pmu format definition 
Adding pmu object which provides interface to pmu's sysfs
event format definition located at:
  ${sysfs_mount}/bus/event_source/devices/${pmu}/format

Following interface is exported:
  struct perf_pmu* perf_pmu__find(char *name);
  - this function returns pmu object, which is then
    passed as a handle to other interface functions

  int perf_pmu__config(struct perf_pmu *pmu, struct perf_event_attr *attr,
                       struct list_head *head_terms);
  - this function configures perf_event_attr struct based
    on pmu's format definitions and config terms data,
    containined in head_terms list.

Parser generator is used to retrive the pmu's format definition.
The generated parser is part of the patch. Added makefile rule
'pmu-parser' to generate the parser code out of the bison/flex
sources.

Added builtin test 'Test perf pmu format parsing', which could
be run like:
	perf test pmu

8f707d843c perf tools: Add config options support for event parsing 
Adding a new rule to the event grammar to be able to specify
values of additional attributes of symbolic event.

The new syntax for event symbolic definition is:

event_legacy_symbol:  PE_NAME_SYM '/' event_config '/' |
                      PE_NAME_SYM sep_slash_dc

event_config:         event_config ',' event_term | event_term

event_term:           PE_NAME '=' PE_NAME |
                      PE_NAME '=' PE_VALUE
                      PE_NAME

sep_slash_dc: '/' | ':' |

At the moment the config options are hardcoded to be used for legacy
symbol events to define several perf_event_attr fields. It is:

  'config'   to define perf_event_attr::config
  'config1'  to define perf_event_attr::config1
  'config2'  to define perf_event_attr::config2
  'period'   to define perf_event_attr::sample_period

Legacy events could be now specified as:
  cycles/period=100000/

If term is specified without the value assignment, then 1 is
assigned by default.

24bff2dc0f perf report: Fix annotate double quit issue in branch view mode 
This patch fixes perf report to not go back two levels when
pressing the 'q' key while annotating in branch view mode.

When pressing 'q' in annotate mode and if the branch source
and target belong to different functions, perf now brings
up the annotation popup menu again to offer the option to
annotate the other branch source or target.

As part of the code restructuring in perf_evsel__hists_browse()
we also fix a memory leak on options[] in case of error.

114382a0ae perf tools: Make perf able to read files from older ABIs 
This patches provides a way to handle legacy perf.data
files.  Legacy files are those using the older PERFFILE
signature.

For those, it is still necessary to detect endianness but
without comparing their header->attr_size with the
tool's own version as it may be different. Instead, we use
a reference table for all known sizes from the legacy era.

We try all the combinations for sizes and endianness. If we find
a match, we proceed, otherwise we return: "incompatible file
format".

This is also done for the pipe-mode file format.

69996df486 perf tools: Enable reading of perf.data files from different ABI rev 
This patch allows perf to process perf.data files generated
using an ABI that has a different perf_event_attr struct size,
i.e., a different ABI version.

The perf_event_attr can be extended, yet perf needs to cope with
older perf.data files. Similarly, perf must be able to cope with
a perf.data file which is using a newer version of the ABI than
what it knows about.

This patch adds read_attr(), a routine that reads a
perf_event_attr struct from a file incrementally based on its
advertised size. If the on-file struct is smaller than what perf
knows, then the extra fields are zeroed. If the on-file struct
is bigger, then perf only uses what it knows about, the rest is
skipped.

bdfebd848f perf record: Add support for sampling taken branch 
This patch adds a new option to enable taken branch stack
sampling, i.e., leverage the PERF_SAMPLE_BRANCH_STACK feature
of perf_events.

There is a new option to active this mode: -b.
It is possible to pass a set of filters to select the type of
branches to sample.

The following filters are available:

 - any : any type of branches
 - any_call : any function call or system call
 - any_ret : any function return or system call return
 - any_ind : any indirect branch
 - u:  only when the branch target is at the user level
 - k: only when the branch target is in the kernel
 - hv: only when the branch target is in the hypervisor

Filters can be combined by passing a comma separated list
to the option:

$ perf record -b any_call,u -e cycles:u branchy

ff2a6617c2 perf annotate: Add missing newline on error message 
If perf.data couldn't find vmlinux image for the given build-id,
it would print error message. However it lacked a newline at the
end, so the output looked like below:

 $ perf annotate --stdio
 No vmlinux file with build id 63b554b2e90f14a4bced200008865e757d3e8b36
 was found in the path.

 Please use:

   perf buildid-cache -av vmlinux

 or:

Fix it by adding a newline at the end of the message. It doesn't affect
the tui output AFAICS. New output will look like this:

On tui annotation, the title was set to name of the target symbol if
user selects the target. However it remained after returning to original
symbol from the target. Fix it.
