Re: Uae4arm: Amiga emulator with JIT and DispmanX

I don't think you would achieve 49fps if every frame is too heavy, and if its not the case the drop will not be the same... 49fps looks like more a sporadic overloading. Jim power is the worse case: every frame is overloading the rpi, only few time it succeed to be smooth. It could be an interesting...

Re: Uae4arm: Amiga emulator with JIT and DispmanX

This is explained by the fact that double buffering is deactivated currently. If rpi is too slow for every frame then you drop directly to 25fps (half of the framerate) instead of being able to retrieve frames from time to time...

Re: Uae4arm: Amiga emulator with JIT and DispmanX

I would not say it's pandora specific but more a choice to give priority to benchmark and amiga cpu speed...hence there is no perfect value. I just improved the fps counter, it was wrongly saying frame drop from time to time despite frames where ok. Now value could be tune again... it's difficult si...

Re: Uae4arm: Amiga emulator with JIT and DispmanX

You have to understand how fastest cpu mode works: it try to emulate the maximum amiga cycle each frame. But by default it does...

Re: Uae4arm: Amiga emulator with JIT and DispmanX

That's what I assumed as well, based on my hacking-around with the previous version. But the problem is, there seemed to be several "master clocks" and a complex network of "A waits on B" dependencies. The semaphore thing looked like, in some circumstances, the emulator core (finish_sound_buffer() ...

If you already have thoses two line, then it should be ok. Otherwise take the version that compile for you.
But why not taking the full latest version in github instead of one modification only ?

Now it looks like access right in linux affect amiga side. If your binary hasn't the execute flag in linux you can't execute it in amiga.
