Yup, just tried, crashes.
Debugging is a bit of a pain at the moment, I compile on my Windows PC, but my Pandora has Wifi issues. It connects, but with in 5-10 minutes is disconnects and will not connect any more. Sometimes it actually kills the Wifi network so the router has to be rebooted. I have tried this on various different networks now (home, work, hotspot, BT Openzone) all with the same result.
I am thinking I should buy a Wifi adapter for the Pandora, so I can GDB in from my desktop PC, it would certainly make things easier, it would also mean I don't have to keep copying things on to a SD card to get them on to the Pandora. Thinking about the Netgear WNA1000M at the moment, not sure if it is the best choice or not.
Decided 'sod it' and ordered a WNA1000M 150 Mbps Wireless-N USB Adapter to be delivered next week, might help getting further with tracking some of these issues

Found a newer version of openal-soft with neon code.
I compiled them for Pandora.
Just throw those in instead of the other libs and the soundlags are gone. Also a bit of speedup overal imho.

We need to get that in the firmware, there are a number of things that use this.

This is the best choice. I've been using a small mini usb dongle and it's actually made the pandora work on a network
The onboard wifi is pretty much a practice joke.. kind of like a piece of performance art to make everybody angry when the wifi randomly stops working.

And here is a build of that lib from latest git:
http://mcobit.openpandora.org/openal-1.15_git-pandora.tar.bz2
Might be better to use this.

Now the biggest performance hit seems to be if you enter large rooms or open areas.
If you can profile this a bit, this game might get really playable even on the CC Pandoras at about 800 MHz.
Edit: Is this the first arm port of avp btw?

No, I didn't mean don't optimise it. I'm sorry if it seemed like I was saying that. I think I probably forgot about the speed differences. I was a bit tired when I wrote that.

I will drop the latest OpenAL lib you have provided (thanks for that) into the next build. I can certainly also run a profile, although I am very hopeful that being able to compile with Os/O2 is going to have decent improvements on performance. Just need to track down why it goes wrong with optimizations. It was crashing in some data loading/processing code, so to take a wild stab in the dark, might be an issue with an uninitialised variable.
I don't know of any other ARM ports. Although there isn't any direct link, ARM devices typically are also GLES devices, and there certainly wasn't GLES support in the code before this port.

Not sure, I don't have access to any Linux PC's, I am a Windows user. I did fix a couple of memory issues on PC though (one buffer overrun and one memory read out of range), but these didn't resolve the issue.

Keep up the good work this is really exciting is amazing how much better the Pandora gets over time thanks to the amazing people in its community

I tried building against that latest OpenAL library, but I get a linker error:
Code:

2> collect2: ld returned 1 exit statusNot entirely sure what this is all about yet. It is possible I would need to upgrade toolchain to use this library (which I am not against doing in principle, not sure when though - I am guessing there is a newer Code Sourcery tool chain than the one I am using which is probably years old now).

You can use the precompiled libs as drop in replacements.
But that error is strange...
You could try to build the lib with your toolchain.
Just get the source from git and use cmake to build it.
What toolchain are you using? Sebt3's toolchain has the pndcmake script that does all the work for you with setting up stuff and options.
Edit: I built this lib with sebt3's toolchain, which has a gcc 4.3 wich caused problems with the examples, so I didn't build them.
With newer gcc versions this should be resolved. Didn't think it would have problems with linking against it.
Maybe really try to build the lib yourself with your toolchain. Might resolve this.

Ah, tracked down the optimized crash, new build will be along shortly.
With regards to tool chain, I have code sourcery installed for ARM Linux installed and am using that, along with a bunch of headers/libs that I must have grabbed from somewhere (can't quite remember where, possibly from a linux tool chain). Based on this it can be tricky for me to compile things, I am not just being lazy, honest

Latest build:
http://repo.openpandora.org/?page=detail&app=com.pawprintgames.avp
Sadly not the improvements of performance I was hoping for, a few more things to try though.

Have just added this to my flags, it is an option which can cause slow down too (ICACHE miss) but lets gamble for now!
