perf tools: Fixup exit path when not able to open events

2011-03-29T16:40:27+00:00

We have to deal with the TUI mode in perf top, so that we don't end up
with a garbled screen when, say, a non root user on a machine with a
paranoid setting (the default) tries to use 'perf top'.

Introduce a ui__warning_paranoid() routine shared by top and record that
tells the user the valid values for /proc/sys/kernel/perf_event_paranoid.

perf tools: Kill event_t typedef, use 'union perf_event' instead

2011-01-29T18:25:37+00:00

And move the event_t methods to the perf_event__ too.

No code changes, just namespace consistency.

perf tools: Fix lost and unknown events handling

2010-11-27T04:41:01+00:00

Fix it by explaining what can be happening and giving the number of processed
and lost events.

Also holler if unknown events were found, that can be due to processing a
perf.data file collected using a newer tool where newer events got added on
reporting using an older perf tool, that or a bug, so ask for a report to be
made.

Works on both --tui and --stdio.

perf scripting: Shut up 'perf record' final status

2010-10-26T17:20:09+00:00

We want just the script output, not internal details about the record phase.

perf: Fix endianness argument compatibility with OPT_BOOLEAN() and introduce OPT_INCR()

2010-04-14T09:26:44+00:00

Parsing an option from the command line with OPT_BOOLEAN on a
bool data type would not work on a big-endian machine due to the
manner in which the boolean was being cast into an int and
incremented. For example, running 'perf probe --list' on a
PowerPC machine would fail to properly set the list_events bool
and would therefore print out the usage information and
terminate.

This patch makes OPT_BOOLEAN work as expected with a bool
datatype. For cases where the original OPT_BOOLEAN was
intentionally being used to increment an int each time it was
passed in on the command line, this patch introduces OPT_INCR
with the old behaviour of OPT_BOOLEAN (the verbose variable is
currently the only such example of this).

I have reviewed every use of OPT_BOOLEAN to verify that a true
C99 bool was passed. Where integers were used, I verified that
they were only being used for boolean logic and changed them to
bools to ensure that they would not be mistakenly used as ints.
The major exception was the verbose variable which now uses
OPT_INCR instead of OPT_BOOLEAN.

perf report: Add progress bars

2010-04-02T19:27:55+00:00

For when we are processing the events and inserting the entries in the
browser.

Experimentation here: naming "ui_something" we may be treading into
creating a TUI/GUI set of routines that can then be implemented in terms
of multiple backends.

Also the time it takes for adding things to the "browser" takes, visually
(I guess I should do some profiling here ;-) ), more time than for
processing the events...

That means we probably need to create a custom hist_entry browser, so
that we reuse the structures we have in place instead of duplicating
them in newt.

But progress was made and at least we can see something while long files
are being loaded, that must be one of UI 101 bullet points :-)

perf tools: Fix non-newt build

2010-03-13T07:23:37+00:00

The use_browser needs to be in a file that is always built and
also we need a browser__show_help stub in that case.
