Bad performance after moving from Android 4.2 to LUbuntu 14.04 with imx6
-
Hello,
in the past week I tried to port my application from Android to LUbuntu 14.04, with the result that the App runs with about 1 fps, while on Andoid it was completly smooth to the eye.
Host system is a x86_64 Ubuntu 17.04.
Target is an imx6 based system running Lubuntu 14.04 with uboot.I downloaded the Qt-everywhere-5.9.1 source from the website.
This is my configuration:
./configure -release -opensource -confirm-license -device imx6 -no-pch -no-opengl -no-xcb -opengl es2 -make libs -prefix /Qt5everywhereopengl/5.9.1 \ -device-option CROSS_COMPILE=arm-linux-gnueabihf- \ -sysroot /media/qtdev/linux_roofs -v
The configuration summary:

Just run 'make'. Once everything is built, you must run 'make install'. Qt will be installed into '/media/qtdev/linux_roofs/Qt5everywhereopengl/5.9.1'.
When runnning the application on the target system I get the output:
QML debugging is enabled. Only use this in a safe environment. qt.qpa.egldeviceintegration: Failed to load EGL device integration "eglfs_viv" libEGL warning: DRI2: failed to authenticate [9;0]Unable to query physical screen size, defaulting to 100 dpi. To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).

Any idea how I can try to solve the performance issue?

Hi. I assumed that you are running your app with eglfs so this error:
qt.qpa.egldeviceintegration: Failed to load EGL device integration "eglfs_viv"
means that you don't have graphics acceleration on your board for Qt app running with eglfs.
Solution for this is to crosscompile Qt again with support for EGLFS for i.Mx6 -> configure script shoud return yes for EGLFS i.Mx6 like this:EGLFS details: EGLFS i.Mx6 .......................... yes
-
@tomasz3dk I tried to run the configure with -eglfs but I still only get
EGLFS details: EGLFS i.Mx6 .......................... no EGLFS i.Mx6 Wayland .................. no EGLFS EGLDevice ...................... no EGLFS GBM ............................ no EGLFS Mali ........................... no EGLFS Raspberry Pi ................... no EGL on X11 ........................... yes
Is there a configure option I can use to force EGLFS on i.Mx6?
-
EGL on X11
This should work also quickly (as EGLFS i.Mx6). It is strange that you has 1 fps.
Most likelly, your distro does not contains such 'es2 over X11 libraries and drivers', and all rendering does as 'software' (with software backend).Is there a configure option I can use to force EGLFS on i.Mx6?
No, it detects automatically at configuring process. Most likelly, your distro does not contains an appropriate development packages with 'es2 over iMX6' drivers and so forth.
PS: Please check it on your side (and, please, do not ask how to do it, as all information can be found in google).
PS2: Also, you can add and XCB support (you need to install additional dev-packages) to check the performance differences. -

I am using the libgles2-mesa-dev package for open gl2.I now compiled the libraries with xcb support and there is not much difference to eglfs. It seems to render a little faster. And even with the xcb platform there is this warning:
libEGL warning: DRI2: failed to authenticate
