Regressions again with sceIo about ppsspp HOT 12 CLOSED

Thanks, I'll look into it. Always mention what game you tested though!

from ppsspp.

The game is Brandish. But the error is also present in f.e. Zwei! with a different value:

Hmm...i'm also noticed, that Mortal Kombat: Unchained was broken between fefc229 and 86a2760
Logs from debug versions: rghost.net/42120803

from ppsspp.

Most likely another scheduling problem where the threads run in the wrong order. @unknownbrackets will have to take a look :)

from ppsspp.

Darn. I don't have any of these three games. Some really interesting stuff is happening in Mortal Kombat, though.

Can you git bisect possibly to find which commit exactly, possibly?

Also, in both it's ending up with a bad sema (a bad name), which is really interesting. I'd like to know why.

This is also super interesting:

stdout: SCREAM: Lib wave didn't take all of our last submit (took 0 of 2048)!
stdout:         calling sceWaveAudioSetSample and hoping for the best.

Anyway, I think I finally found the difference. In the broken one it is never returning to user_main after this:

Left callback 295 - MKMSCallback
Context saved (return from callback): 276 - user_main - pc: 08a2775c
Context loaded (return from callback): 278 - callbacks - pc: 089ecddc

So then it goes into an idle loop. Obviously user_main is never becoming runnable again which is wrong. I'm guessing it has isProcessingCallbacks stuck, which means my fix for ff7e1d7 probably broke one thing and fixed another.

If you go back to 9cd47e2 does it work?

from ppsspp.

Checked commits 9cd47e2 and ff7e1d7 - game MK: Unchained works on both of them. (Release)

a bit offtopic: Btw, would be good to have some hidden/private section on forum if devs have no stuff for testing. ;P Or i'll go to IRC, and we talk about it. ;D

from ppsspp.

I could make a hidden dev forum but most dev discussions are fine to have right here in public on the github issue tracker. If you feel otherwise, yeah, there's always IRC :P

from ppsspp.

@B1ackDaemon: yes, please come to IRC, could probably narrow this down faster.

So, that's interesting. Must be a later commit... hmm.

Does it work in 000884f? Sorry.

from ppsspp.

Okay, I think I have an idea at least. Does it work on the tip of this branch?

https://github.com/unknownbrackets/ppsspp/tree/scheduling2

Specifically, does a1a4a02 fix it?

@Darth1701 sorry for hijacking a bit, would like to know if this fixes it for you also - or else, more of the logs would help.

@unknownbrackets Don't worry, that is quite OK. :)

I still have the error in Zwei!:

althought it doesn't hurt the game itself. I could be sound related.

In Brandish the error is gone.

from ppsspp.

Oh, I fixed an error recently with another game that was like that. I think that's a separate bug, probably.

So sounds like Brandish is fixed - hurray. I'll send a pull then.
