profiling: Adds initial UProf support across clutter UProf is a small library that aims to help applications/libraries provide domain specific reports about performance. It currently provides high precision timer primitives (rdtsc on x86) and simple counters, the ability to link statistics between optional components at runtime and makes report generation easy. This adds initial accounting for: - Total mainloop time - Painting - Picking - Layouting - Idle time The timing done by uprof is of wall clock time. It's not based on stochastic samples we simply sample a counter at the start and end. When dealing with the complexities of GPU drivers and with various kinds of IO this form of profiling can be quite enlightening as it will be able to represent where your application is blocking unlike tools such as sysprof. To enable uprof accounting you must configure Clutter with --enable-profile and have uprof-0.2 installed from git://git.moblin.org/uprof If you want to see a report of statistics when Clutter applications exit you should export CLUTTER_PROFILE_OUTPUT_REPORT=1 before running them. Just a final word of caution; this stuff is new and the manual nature of adding uprof instrumentation means it is prone to some errors when modifying code. This just means that when you question strange results don't rule out a mistake in the instrumentation. Obviously though we hope the benfits out weigh e.g. by focusing on very key stats and by having automatic reporting.

profiling: Parse --clutter-profile and CLUTTER_PROFILE= options As we have for debugging, this adds the ability to control profiling flags either via the command line or an environment variable. The first option added is CLUTTER_PROFILE=disable-report This also changes the reporting to be opt-out so you don't need to export CLUTTER_PROFILE_OUTPUT_REPORT=1 to see a report but you can use CLUTTER_PROFILE=disable-report to disable it if desired.

profiling: Allow limiting statisics just to picking This suspends and resumes all uprof timers and counters except while dealing with picking, so as to give more focused statistics. Be aware that there are still some issues with this profile option since there are a few special case counters and timers that shouldn't be suspended; noteably the frame counters are incorrect so the per frame stats can't be trusted.

profile: Update to uprof-0.3 dep for --enable-profile When building with --enable-profile we now depend on the uprof-0.3 developer release which brings a few improvements: » It lets us "fix" how we initialize uprof so that instead of using a shared object constructor/destructor (which was a hack used when first adding uprof support to Clutter) we can now initialize as part of clutter's normal initialization code. As a side note though, I found that the way Clutter initializes has some quite serious problems whenever it involves GOptionGroups. It is not able to guarantee the initialization of dependencies like uprof and Cogl. For this reason we still use the contructor/destructor approach to initialize uprof in Cogl. » uprof-0.3 provides a better API for adding custom columns when reporting timer and counter statistics which lets us remove quite a lot of manual report generation code in clutter-profile.c. » uprof-0.3 provides a shared context for tracking mainloop timer statistics. This means any mainloop based library following the same "Mainloop" timer naming convention can use the shared context and no matter who ends up owning the final mainloop the statistics will always be in the same place. This allows profiling of Clutter with an external mainloop such as with the Mutter compositor. » uprof-0.3 can export statistics over dbus and comes with an ncurses based ui to vizualize timer and counter stats live. The latest version of uprof can be cloned from: git://github.com/rib/UProf.git
