Profiling Glfw
Monkey Targets Forums/Desktop/Profiling Glfw

| I got Monkey to work on my ARM chromebook, but, while most demos are fast under Glfw, some demos, like Monkenstein are just unusable slow. Like not even 1 fps. How can I profile/find the issue here? |
| ||
| is it slow under HTML5 as well? i usually try the Chrome profiler for javascript first for general profiling. but for glfw specifically, i use "very sleepy" http://www.codersnotes.com/sleepy you may need to modify the VC++ project file to allow debug output to get detailed info. i think it's off by default. |

| No HTML5 is fast; faster than Glfw on my other laptop actually... Which I also find slightly disturbing :) Only Glfw and only with a few of the bananas. Sleepy looks nice, but we're talking about a Ubuntu (Chrome) ARM laptop ; no Windows, no VC++ :) I'll try gprof to try to find what's going on. |

| what graphics card does the chromebook have? maybe the chrome OS doesnt have the right drivers? Have you tried any other games made with other languages? (with 3d rendering) |

| The Chrome book automatically has the right drivers with Ubuntu, because Ubuntu uses the Linux Google drivers which are included with ChromeOS. And they work very well as all WebGL/OpenGL runs really well/fast for such low spec; I have many open source games running well as well as emulators which use OpenGL for acceleration. I did come closer by trying to figure out what is wrong, because something is very wrong :) When compiling the binary with profiling info or while trying to compile for release, so not debug, it seems all to boils down to software using GrabImage; they run very slow or, when compiling for Release, seg with a memory violation: Without gbd: Monkey Runtime Error : Memory access violation /home/tycho/MonkeyPro75d/modules/mojo/graphics.monkey<105> /home/tycho/MonkeyPro75d/bananas/skn3/monkenstein/monkenstein.monkey<113> /home/tycho/MonkeyPro75d/modules/mojo/app.monkey<43> {{~~/home/tycho/MonkeyPro75d/modules/mojo/graphics.monkey<105>~~}} +GameDelegate.StartGame;/home/tycho/MonkeyPro75d/modules/mojo/app.monkey<43> Self:GameDelegate=@1c99ca0 +myApp.OnCreate;/home/tycho/MonkeyPro75d/bananas/skn3/monkenstein/monkenstein.monkey<113> Self:myApp=@1c99150 levelData:String="7777777777772222244444447000000000070000040000047000000000074444440000047000221200000000000000047000..." index:Int=0 +Image.GrabImage;/home/tycho/MonkeyPro75d/modules/mojo/graphics.monkey<105> Self:Image=@(nil) x:Int=0 y:Int=0 width:Int=1 height:Int=64 frames:Int=64 flags:Int=0 With gdb: [New Thread 0x7549a450 (LWP 13260)] [Thread 0x7549a450 (LWP 13260) exited] [New Thread 0x7549a450 (LWP 13261)] [New Thread 0x70aff450 (LWP 13262)] Program received signal SIGSEGV, Segmentation fault. 0x0004435e in Array<c_Frame*>::Length() const () and stacktrace; #0 0x0004435e in Array<c_Frame*>::Length() const () #1 0x00038392 in c_Image::p_GrabImage(int, int, int, int, int, int) () #2 0x00032408 in c_myApp::p_OnCreate() () #3 0x000356a0 in c_GameDelegate::StartGame() () #4 0x0002c1f8 in BBGame::StartGame() () #5 0x0002ddbc in BBGlfwGame::Run() () #6 0x0002e054 in BBMonkeyGame::Main(int, char const**) () #7 0x00040506 in main () To me this makes no sense, but what can I do to help Monkey? :) (Edit: this is a clean 75d install so there is nothing changed in Monkenstein) |
