2012-05-02perf ui: Add gtk2 support into setup_browser()Namhyung Kim
Now setup_browser can handle gtk2 front-end so split the TUI code to ui/tui/setup.c in order to remove dependency. To this end, make ui__init/exit global symbols and take an argument. Also split gtk code to ui/gtk/setup.c.

There were some combinations of these switches that are not so appropriate IMHO. Since there are implicit priorities between them and they worked well anyway, but it ends up opening useless duplicated events. For example, 'perf stat -t <pid> -a' will open multiple events for the thread instead of one. Add explicit checks and warn user in perf_target__validate().

2012-05-01perf stat: Fix case where guest/host monitoring is not supported by kernelStephane Eranian
By default, perf stat sets exclude_guest = 1. But when you run perf on a kernel which does not support host/guest filtering, then you get an error saying the event in unsupported. This comes from the fact that when the perf_event_attr struct passed by the user is larger than the one known to the kernel there is safety check which ensures that all unknown bits are zero. But here, exclude_guest is 1 (part of the unknown bits) and thus the perf_event_open() syscall return EINVAL. To my surprise, running perf record on the same kernel did not exhibit the problem. The reason is that perf record handles the problem by catching the error and retrying with guest/host excludes set to zero. For some reason, this was not done with perf stat. This patch fixes this problem.

2012-05-01ktest: Fix reboot on success stopping all rebootsSteven Rostedt
The change to let individual tests decide to reboot the machine on success of the entire test also prevented errors from rebooting when an error was detected. The "no_reboot" variable was only cleared if the test had reboot_on_success set. But the no_reboot variable also prevents the test rebooting when an error was detected even when REBOOT_ON_ERROR was set. Add a new "reboot_success" variable that is used to determine if the test should reboot on success and not touch the no_reboot variable. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2012-05-01ktest.pl: Fix combined usage of BISECT_REVERSE and BISECT_SKIPRuss Dill
When BISECT_REVERSE and BISECT_SKIP are used together with boot or test testing, build failures are treated as boot or test failures and 'git bisect bad' is executed instead of 'git bisect skip'. This is because the $ret value of -1 is treated as a build failure, but the $reverse_bisect logic does not properly handle this. Simple fix, only invert it if it is positive.

2012-04-25parse-events: Handle opcode parsing errorVaibhav Nagarnaik
If an invalid opcode is encountered in parsing event print format, the trace-cmd calls exit() without parsing any other events. This patch adds handling for such an error where the get_op_prio() is called. If the return value is -1, then the event print format parsing is skipped and parsing continues.

2012-04-25parse-events: Handle invalid opcode parsing gracefullyVaibhav Nagarnaik
If an invalid opcode is encountered, trace-cmd exits with an error. Instead it can be treated as a soft error where the event's print format is not parsed and its binary data is dumped out. This patch adds a return value to arg_num_eval() function to indicate if the parsing was successful. If not, then the error is considered soft and the parsing of the offending event fails.

2012-04-25perf: Have perf use the new libtraceevent.a librarySteven Rostedt
The event parsing code in perf was originally copied from trace-cmd but never was kept up-to-date with the changes that was done there. The trace-cmd libtraceevent.a code is much more mature than what is currently in perf. This updates the code to use wrappers to handle the calls to the new event parsing code. The new code requires a handle to be pass around, which removes the global event variables and allows more than one event structure to be read from different files (and different machines). But perf still has the old global events and the code throughout perf does not yet have a nice way to pass around a handle. A global 'pevent' has been made for perf and the old calls have been created as wrappers to the new event parsing code that uses the global pevent. With this change, perf can later incorporate the pevent handle into the perf structures and allow more than one file to be read and compared, that contains different events.

2012-04-25tools/events: Add files to create libtraceevent.aSteven Rostedt
Copy over the files from trace-cmd to the Linux tools directory such that applications like perf and latencytrace can use the more advanced parsing code. Because some of the file names of perf conflict with trace-cmd file names, the trace-cmd files have been renamed as follows: parse-events.c ==> event-parse.c parse-events.h ==> event-parse.h utils.h ==> event-utils.h The files have been updated to handle the changes to the header files but other than that, they are identical to what was in the trace-cmd repository. The history of these files, including authorship is available at the git repo: git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git The Makefile was also copied over, but most of it was removed to focus on the parse-events code first. The parts of the Makefile for the plugins have also been removed, but will be added back when the plugin code is copied over as well. But that may be in its own separate directory.

Move the trace-event-parse.c code that originally came from trace-cmd into their own files. The new file will be called trace-parse-events.c, as the name of trace-cmd's file was parse-events.c too, but it conflicted with the parse-events.c file in perf that parses the command line. This tries to update the code with mimimal changes. Perf specific code stays in the trace-event-parse.[ch] files and the common parsing code is now in trace-parse-events.c and trace-parse-events.h.
