Random freezing during games on Odroid XU4 & N2 #133

Closed Cee123 closed 5 years ago

Cee123 commented 5 years ago

After about 10-20 minutes of play into just about 3DO game on the Odroid XU4 and N2, the game just freezes. It happens often with -Captain Quazar -Gex -PO'ed -Road Rash -Crash 'n Burn -Corpse Killer -As well as several others

More information - all of these files are CHD format. I'm using The Retro Arena, latest version, with 4DO installed from source.

I've tried both bioses, panafz1.bin and panafz10.bin.

Not really sure what's going on there.

Is the system freezing or retroarch / 4do?

trapexit commented 5 years ago

What are your settings? Can leaving say, Road Rash, in attract mode for 10+ minutes trigger it?

Cee123 commented 5 years ago

Ah sorry, I should've been more specific. My bad. It seems to just freeze on 4DO, but the retroarch menu etc is still useable. Which is strange.

Cee123 commented 5 years ago

Interesting, I had not checked that setting. I'll check if that setting is turned on or off. Maybe it's on by default.

Cee123 commented 5 years ago

I don't think it's to do with attract mode (not quite sure what that is)

Settings I have under options Bios: Panasonic fz-10 Font: off CPU overclock: 1.0x Threaded DSP: on High resolution: off Nvram storage: per game Active devices: 1 Madam matrix engine: hardware

Under video settings Threaded video: on Vsync: on Hard GPU sync: off Bilinear filtering: on Aspect ratio: core provided The rest of the settings are pretty much default

Turn off Threaded DSP and recheck please.

"attract mode" is just a general term for the demo that a game runs (like an arcade game showing game play and an intro over and over).

Aha, yeah it does do that. It does freeze during the attract mode sometimes for different games.

Turn off Threaded DSP and recheck please.

Alright, will try that and see if it works. Thanks!

Cee123 commented 5 years ago

Awesome thanks! You're a legend. So far so good. Seems to be that the threaded DSP was causing the problem. No idea why that setting was turned on.

Cee123 commented 5 years ago

You were right. It was the threaded DSP that was causing it to freeze randomly.

trapexit commented 5 years ago

I thought it was marked as experimental but I'm not seeing it now. It might be worth turning it off altogether. There are clear race conditions in the implementation that will be difficult to address without significant rewrite.

Cee123 commented 5 years ago

Oh OK. Interesting. Sounds like a pretty big task to do a rewrite. Yeah I had turned that setting off altogether and suddenly everything now seems to be running better than what it was before.
