to get EGL to work partially: http://git.directfb.org/?p=openwrt/packages.git;a=blob;f=directfb/patches/raspberrypi-workaround.patch;hb=9054195ce15a92b59b5f3022e6daffd84a5d2863 You might also find this 'inspiring' for further work (section Caveats): http://www.qnx.com/developers/docs/6.5.0/index.jsp...

Can someone comment on the performance and usability when using openwrt? In particular I would like to know:
- is it hard float version?
- are there pre-compiled packages?
- anyone tried xbmc on openwrt?
- anything else?

gregd72002

Maribu, can you confirm that DirectFB examples work on your version? in particular I am interested in df_andi In the past I was successful to get this running with 50% cpu usage @ 60fps when using EGL however something was not right with the background - it was missing. If you could fix this (so df_...

gregd72002

Maribu, I just gave it a try and it does not look like EGL acceleration is working...

What you have is rendering over linux fbdev and not EGL...

If you add to your .directfbrc:
system=egl

and try run something you will see what I mean

gregd72002

I think we have solution:

gregd72002

Maribu, great work!! I spent on this very long time as well... but it looks like I missed the right directfbrc configuration!

Have you tried compiling ilixi or some demos?

I will give it a try later on today.

Thanks again and keep it up!

gregd72002

Right... looks like we are on track (early next month we should get it):

Though, got a few ideas I want to try to get this working now

gregd72002

Guys, it looks like this has already been done. From what I found DirectFB team is looking into getting openwrt on raspberry pi. Look into their GIT repo and you will find openwrt patches for rpi: http://git.directfb.org/?p=openwrt/kleistpark.git;a=summary http://git.directfb.org/?p=openwrt/packages...

gregd72002

Is there any update on this? I'm just trying to get this working as well... and before I start digging around with the code would need to know what is the current state...

gregd72002

can u post 'dmesg'?

The root cause is in regression bug in 3.1.x and 3.2.x kernels..
Kernel 3.3 is known to resolve the issue.

https://github.com/raspberrypi/linux/issues/66

Anyone tried kernel 3.3?

Hi, I'm trying to build qt5 on the board itself as described in: http://qt-project.org/wiki/RaspberryPi So far I've got all the sources HF patched but the configure process for qtbase fails. Any advice on this? pi@raspberrypi ~/qt5/qtbase $ ./configure -opengl es2 -opensource -confirm-license -optim...

Hi guys, I've got similar problem, though my card is fully recognized and modules are loaded. The problem is it does not connect.. [ 3.067669] usb 1-1.2: new high speed USB device number 4 using dwc_otg [ 3.364125] usb 1-1.2: New USB device found, idVendor=050d, idProduct=705a [ 3.387506] usb 1-1.2:...

gregd72002

Is there any update on this? I'm really looking forward to get my hands on DirectFB + GTK

gregd72002

i gave up on it after a couple of hours.... it spat its dummy out over the xml parser and don’t really think its worth the effort to fix it... i think it's quite clear that the RPi is of no use for compiling code on,at least nothing of any significant size.... i know by using the -j switch on the "...

gregd72002

I tried to compile it on the RPi itself some point last week... after 3 days I gave up

Remember to be on 224MB ram, otherwise it might not compile

gregd72002

Right, so OpenGLES toolkits/libraries that do not require X server?

Still libSDL seem to be a candidate, any others?

gregd72002

Hi, I tried to lookup some OpenGL toolkits to simplify some development (i.e. bitmap loading & keyboard/mouse handler). It looks like there are plenty of them but they all require X server (i.e. FreeGLUT) Anyone could recommend any toolkit that could be easily used on RPi without the need for X serv...

What about VGA->DVI-A cable? Most monitors/displays that accept DVI input are actually DVI-I type so this mean they can accept DVI-A as well as DVI-D.

gregd72002

shaurz, it looks like you are on the right track. I combined your EGL initiation code (canvas-egl) into my glmark2 build and I got it running. Here are the results: ======================================================= glmark2 2012.03 ======================================================= OpenGL ...

gregd72002

shaurz, do you work still on X11 version or a direct FB (framebuffer but not facebook ;) ) version? I got my FB version of glmark2 pretty much complete. It configures, compiles and runs fine without any additional LD loaders on archlinux. Also the absolute minimum in terms of dependencies is require...

gregd72002

This should not be too difficult... Neither (I think) you need any X11 drivers/knowledge. I'm on a 'similar' boat to you trying to get this working. Looking at the sources the canvas*.cpp files must be ported to RPi; or preferably - a RPi version of them to be written. Meantime, I created a patch to...

gregd72002

Right, I will answer my own question - the error was due to me being on 32MB GPU ram. Moving to 64MB GPU ram solved the problem

Thanks

gregd72002

<t>this worked (adding the right LDFLAGS into Makefile). Thanks! I had to install additionally libegl and libgles as well as add /opt/vc/lib into ld configuration as it was complaining about libopenmaxil.so. Now when I run it I get: [root@alarmpi hello_triangle]# DIS...
