My plugin crashes

[kralyk]

Hi,
Im trying to make a vsh plugin,
but it crashes the PSP when I load a game from XMB (its not unloaded correctly?)

the code:

Code: Select all

int module_stop(void)
{
  sceKernelTerminateDeleteThread(mainthread);
  sceKernelSelfStopUnloadModule(1, 0, NULL);
  return 0;
}


int module_start(SceSize args, void *argp)
{
	mainthread = sceKernelCreateThread("My__Plugin", pluginMain, 6, 0x4000, 0, NULL);
	if (mainthread >= 0)
	{
    sceKernelStartThread(mainthread, args, argp);
	}

	return 0;
}

Exports:

Code: Select all

PSP_BEGIN_EXPORTS

PSP_EXPORT_START(syslib, 0, 0x8000)
PSP_EXPORT_FUNC(module_start)
PSP_EXPORT_FUNC(module_stop)
PSP_EXPORT_VAR(module_info)
PSP_EXPORT_END

PSP_END_EXPORTS 

Thanks for any help!

You shouldn't use sceKernelSelfStopUnloadModule(1, 0, NULL); in module_stop.

That would return an error, since your module is already being stoped. Anyways, I don't know if this is reason enough for the crash, there maybe other reason.

Ok, I removed that, but still crashes (in fact crashes even with module_stop just returning 0)

Here is the pluginMain function:

Code: Select all

int pluginMain(SceSize args, void *argp)
{
  SceCtrlData pad;

  sceKernelDelayThread(10*100000);

  sceCtrlSetSamplingCycle(0);
  sceCtrlSetSamplingMode(PSP_CTRL_MODE_ANALOG);

  while (1)
  {
    sceCtrlPeekBufferPositive(&pad, 1);
    if ((pad.Buttons & PSP_CTRL_SQUARE) && (pad.Buttons & PSP_CTRL_LTRIGGER))
    {
      blit_string(30, 27, "HELLO WORLD!", 0xffffffff, 0x0);
    };

    if(sceKernelFindModuleByName("msvideo_plugin_module"))
    {
	   blit_string(30, 30, "Video player loaded.", 0xffffffff, 0x0);
    }

    sceDisplayWaitVblankStart();
  }
  return 0;
}

No idea?
Maybe someone could tell me about some open source plugin (besides piKey) which I could look into source of ......?

I dont have any experience making vsh plugins and I cant find any open source ones... =(

Add a short delay in the while cycle, sceKernelDelayThread(1000) is enough...

[kralyk]

wow thanks ne0h that did help.
So I guess the loop was too tight...
I though sceDisplayWaitVblankStart(); would be enough but apparently not...
thanks.
