[directfb-dev] directfb profiling
hi, i am currently working on the DFB savage driver and i would like to see how it performs. i am currently running df_layer with an mpeg1 file and i changed df_layer to use a YV12 surface in stead of YUY2 to test the savage driver overlays. i am very new to profiling and its techniques and currently i am just using top to see how much cpu it uses. when i run df_layer 7 pids show up so i assume this is the different threads for everything. i sprinkled some printfs over the directfb code and i found out that there is a process for main, keyboard events, mouse events, libmpeg3 video, libmpeg3 audio and i can't figure out what the other two threads are. i placed printf's at every function registered by pthread_create. any ideas any one ? also has anyone turned on the profiling flags in gcc with directfb ? does it work ? i have not used the profiling features of gcc before. btw, i got YUY2, UYVY and YV12/I420 overlays to work with the DFB savage driver. any help appreciated. cheers, alex -- Info: To unsubscribe send a mail to email@example.com with "unsubscribe directfb-dev" as subject.
