Still traps at the youtube page and still traps at avcode56, Attached trap file.

David,

OS2user, I am not that savvy with programs like this.  I installed it, but don't know how to set it up or what I would use it for.

Do you have a WINx box on your LAN/network that you could try connecting to?

Hi Dariusz

I have no network set up.  I essentially use just one machine.

I just tried the SandyBridge version with the lastest OS/4 kernel and FF works now

try this http://hobbes.nmsu.edu/download/pub/incoming/freerdp-wpi-20190301.zip
it also requires AVX

Dave, I just tried the SandyBridge version with the lastest OS/4 kernel and FF works now.  Don't know why it did not start before.  Cannot test further since I am at work.

I take it you are using the AVX enabled build of the OS4 kernel. Is that bad web page now working for you with avcod56 and the Sandybridge Firefox?
If not I can build some test builds of FFmpeg this evening.

That SandyBridge version with the latest AVX OS/4 kernel is working fine.   That bad web page is working fine.  Everything loads fine.  No crashes.  This may be the best so far.  Only time will tell.

I spoke too soon.  It appears to crash every time I go to youtube videos and it tries to load a video.  Attached are the trap messages.  ffturbo does not work with this version. It won't start.

Dave, I won't know until I get home from work to test it and yes it is the AVX enabled OS/4 latest kernel.

There's already one open about looking into the feasibility of adding AVX support to the IBM kernel, which you probably can't access. Not much there besides a description of the needed feature.
The problem is that during a context switch, the AVX registers need to be preserved. Those registers can be up to 512 bits wide. Think of what happens if two programs are using AVX when the OS switches between them. I doubt that we'll see AVX support in the official kernels anytime soon.
You may have hit on a bug in the OS4 kernel, at least OS4USER is aware of your crash.
Would still be interesting to know what function was crashing in libavcodec though I wouldn't be surprised if something just wasn't aligned correctly. Interesting that the AVX enabled Firefox didn't run for you as well. Did it generate a trp?
Exceptq could also use an update to correctly disassemble AVX opcodes. Luckily Lars can spot them.

Should I open a ArcaOS ticket concerning AVX?

PS- I posted another graphic of the CPU cabilities (feature flags) above at reply #55.

Yes, it seems to be incomplete, only showing up to SSE2.
Hmm, looking at Intel's site, it does seem to support AVX, which is what I was wondering.

I can verify it  does support AVX.  Attached pic

Hi David, that crash looks like one I get now and again, I believe font related.
Have you tested with the Firefox build that OS4USER mentioned?

Dave, I tried the SandyBridge port of FF and the program would not start when using the OS/4 kernel and loader. This is when I decided to post here to see what could be done. I did not try it with the OS/2 kernel.  The noAVX version is working great with the OS/4 kernel. The lastest build of your FF 45.9.0 pentium is the best yet.  I am having no problems watching videos and accessing web pages.  I no longer have to boot to Windows to get reliable internet.  Again, thanks to all who continue to donate their time and effort to make using ArcaOS and other versions more enjoyable.

I made a quick and dirty PMChart PNG icon.
In general, does the full file name of those PNG files matter when the user or the system has to assign it to a WPS object?

Compared with the *.ICO equivalent (e.g. HELLO.ICO being a default icon for a HELLO.EXE in the same directory), that is.

The PNGs can be whatever name you want them.  I just give long descriptions to help people know what the PNGs can be used for.   The name does not matter when assigning the PNG or the location where you  assigned it from.  At least that is my observation.

I just installed the noAVX kernel and my traps have disappeared.

P.S.
It was suggested by BWW to remove libc-debug 0.6.6-40  and install libc-debuginfo instead of it.

Done.  Thanks OS4User.

Hi Lars

I have attached a picture of the CPU flags.

Looking at it again:
If it is true that all SSE/AVX code in AVCODE56.DLL is handwritten in assembler then I suspect either one of 2 possibilities:
....

To Lars:

What you saying is quite possible. One more way to check it -  is test OS/4 kernel without AVX support.

To David:

Pls, open  your site   on this test kernel http://gus.biysk.ru/os4/os4krnl_noAVX.zip

Thanks for all the responses.

I just installed the noAVX kernel and my traps have disappeared.  This is just preliminary but I have no problem going to that web site and others so far.  So far, so good.

My avcode56.dll is the same size and date on both my ArcaOS 5.02 and ArcaOS 5.03 partitions.

Attached a pic of my type of CPU info.  While modifying this message, I had another trap which I have attached.  I just remembered that this is another instance when a trap occurred. However, so far, this one trap is all I have encountered so far with the noAVX.

By the way Dave, I just installed the debug versions you recommended after this last trap.  So far though, Firefox is much more stable with the noAVX kernel version.  It feels good to be able to use FF again without it continually crashing when using the OS/4 kernel.

I use OS/4 kernel on one of my partitions.

Presently, I have been using test build SVN5447.

i noticed that when I try to use FF 45.9.0, it always traps at this web page.   It occurs with FFTurbo enabled or disabled.

https://beforeitsnews.com/v3/

If I boot using the OS/2 loader and kernel, the traps disappear.

Attached are a couple of trap logs.

The traps occur on earlier test builds of the OS/4 kernel also.

Thanks to both Daves: Graser and Yeo. And everyone else.

The unpack (Yeo) and creating directories (Graser) were what I needed.

I have attached a zip file with the app files - arranged in a directory structure that more closely matches AOS and ECS. And as Dave Graser said, it appears to work. I will also upload this in the next couple of days to Hobbes.

I made a quick and dirty PMChart PNG icon.

Made one more PNG.
