Hi,

Trying to Build QT5.8 with Buildroot master tree causes the following error:

Try to add (untested):

# Avoid X11 header collision, use generic EGL native types
DEFINES += QT_EGL_NO_X11

to src/plugins/platforms/eglfs/eglfs-plugin.pro (same as all/many other eglfs related
project files do, even eglfs_x11.pro ;-) )...

Adding that define to eglfs-plugin.pro is sufficient to get qtbase to
build properly.

However when I launch the Cinematic demo I get errors that it can't find
the eglfs_kms device:
# CinematicExperience-demo -platform eglfs
qt.qpa.egldeviceintegration: Failed to load EGL device integration
 "eglfs_kms"
qt.qpa.egldeviceintegration: Failed to load EGL device integration
 "eglfs_kms_egldevice"
...
EGL Error : Could not create the egl surface: error = 0x300b

(note that kmscube is working fine)

I'm trying to understand how it works in Yocto but something definitely
needs fixing.

Regards,
Gary

Copied missing files from tarbal, don't know why it's not copying, but
still see black screen on widgets.

Thanks for testing.

I think we should treat this issue on a separate thread as I also see
the same with Qt5.6.2.

It seems we made progress with Qt5.8 with Peter's patches.

Peter,

Do you plan to submit your two patches formally?

Thanks

OK, so we need to investigate framebuffer issue? do you have any suggestions.

QOpenGLFramebufferObject: Unsupported framebuffer format.
QOpenGLFramebufferObject: Framebuffer incomplete, missing attachment.

If I understand correctly the same 4.9.13 kernel that you use with
Gary's rootfs is able to launch the Qt5 Cinematic just fine, right?

So we need to understand what changed from Gary's rootfs compared to
master that caused the regression.

Yes can do. No problem with the first one, for the second one I need
to investigate first on which additional configure option the building
of libQt5EglFsKmsSupport.so depends...

Actually I wonder why the first patch is needed in this case. How does
the eglfs plugin build for Vivante for instance since the failure
happens in a common file?

Otherwise, I confirm I have "black picture" issues on Qt5.8 with the
Cinematic demo.

However, I've made a discovery regarding the DRI configuration (to
avoid hardcoding the device). It is actually documented well on Qt
website:
http://doc.qt.io/qt-5/embedded-linux.html#eglfs-with-eglfs-kms-backend
"The KMS/DRM backend also supports custom configurations via a JSON
file. Set the environment variable QT_QPA_EGLFS_KMS_CONFIG to the name
of the file to enable this."

Here is my JSON file for Hannstar display:
{
  "device": "/dev/dri/card1",
  "hwcursor": false,
  "pbuffers": true,
  "outputs": [
    {
      "name": "VGA-1",
      "mode": "off"
    },
    {
      "name": "HDMI-1",
      "mode": "off"
    },
    {
      "name": "LVDS-1",
      "mode": "1024x768"
    }
  ]
}

This avoids the patch mentioned before:

Don't know but I never find to explicitly mentioned the kmscube ran
w/o any device argument for 5.6.2 and 5.8

I'm not sure to understand your remark.

Note that here I'm only talking about Qt5.8 with Mesa17.0.1.

Yes my previous image with Qt5.6.2 and Mesa13.0 from Christian tree
didn't require to specify the node.

Also, kmscube, which has nothing to do with Qt, now requires you to
specify the device (using latest version on master).

Previously it was checking the drm name against an "approved" list of
devices. Specifying the device manually is therefore more flexible
since it doesn't require source code modification to get it working.

Finally, I've been able to see the covers of the Cinematic demo using
Qt5.8 + Mesa17.0.1 (Etnaviv) by disabling the "Show movies cover
lighting" option (bottom left corner). So I guess it's an Etnaviv
support issue in Mesa that makes the black rectangles.

Gary

Yes, made the setting now the black widget show the picture and did
you find Description on specific widget open doesn't show proper
letters.

Thanks, this did the trick!

Now I can succesfully lauch the Cinematic demo using Buildroot master.
Thanks to Peter for his two Qt5.8 fixes!

Any suggestions for a proper fix on the 'black screen' problem?

Thanks
