Cool...

Is this on the other Branch different?

ptitSeb · Dec 3, 2015

yep, on unstable branch, it loads bcm_host, then vcos, then EGL...

Honestly you should copy my whole loader.c and loader.h

Yeah, I can probably just do that, should not be too difficult to converge here.

lunixbochs · Dec 3, 2015

Just remember I changed the way PUSH_IF_COMPILING works due to remote stuff, so you should delete the FORWARD_IF_REMOTE macro and use the old PUSH_IF_COMPILING. I also don't use LOAD_GLES_OES, instead using PROXY_OES

ptitSeb · Dec 3, 2015

It's done.

@nighteagle: you can try again (you will need to "cmake" again if you used git pull to update).

lunixbochs · Dec 3, 2015

Oh, you shouldn't need the -DBCMHOST=1 define anywhere if you integrate my rpi support properly. You should also look at my glx initialization, which automatically tries LIBGL_FB if normal window fails.

Ah Okay i will test...

Damn..

Should be fixed now.

nighteagle · Dec 4, 2015

100% Build

Now i will test with the IR_CAM

nighteagle · Dec 4, 2015

Hi,

so is starting and running and also i can see the text perfect..

But it looks like there is not hardware accelerated. But also with only software rendering i had 15fps.

I see 0,2fps and the image is not move.

With the unstable branch from lunixbochs i have about 40fps.

The image is only 382x288px

Some linking not correct? Wrong lib?

It takes also a long time to start.. about 10sec. then ist makes an Fullscreen and after that it comes the little preshow picture.

Then it writes at start round about 30fps and decrease to 0,2fps

Keyboard response is also slow... sometimes not response...

ptitSeb · Dec 4, 2015

Something is wrong indeed.

Try to use with LIBGL_FB=1 or without it

You can try also with LIBGL_BATCH=2

Also, if you can run a "sudo perf top" in another terminal to see what's going on.

nighteagle · Dec 4, 2015

Hi,

without LIBGL_FB=1 i became an EGL Error Bad Display 0x3008.

Also if i use LIBGL_BATCH=2

The lunixbochs branch start with and without the LIBGL_FB=1.

So Raspberry PI Debian don't have perf... i find no package for that?

Linux-Tools is not enough to start perf.. so i fin dan RPI Monitor.

I will test...

nighteagle · Dec 4, 2015

Ah no.. the RPI Monitor is only for Hardware surveillence.

Can't find the linux-tools-4.1.13-v7+ for the RPI....

Other ideas?

ptitSeb · Dec 4, 2015

lunixbochs build use LIBGL_FB=1 automaticaly if needed.

Can you try with both "LIBGL_FB=1 LIBGL_BATCH=2" ?

nighteagle · Dec 4, 2015

Hi

"Can you try with both "LIBGL_FB=1 LIBGL_BATCH=2" ? "

the same Problem. 0,2fps.. it looks like it stops and no moving from the kamera appear on the image.

ptitSeb · Dec 4, 2015

Something goes wrong with some rendering, but I have no idea what. It cannot be debugged remotly at this stage... Some "printf" has to put (either in the software or glshim) to understand where the software is stuck...

lunixbochs · Dec 4, 2015

ptitseb: do you do the same batched rendering for bitmaps as me? that (or streaming textures, or an automatic atlas texture) is the only way you'll get any performance out of a font renderer that calls glBitmap for individual glyphs.

No, I don't batch, I had issue with batching glBitmap with Blender so I stopped. But yes, that could be the issue here if there is a lot of glBitmap calls. But to get 0.2fps (instead of 40fps) it should have hundreds of such calls.
