EGLFS for IMX6Q

[gregoryciapa]

Hi,

I am cross compiling Qt with Buildroot and GCC Linaro for a carrier board based on IMX6Q.

I would like to use eglfs platform plugin but i am confused about the list of associated backends available.

QPA backends:
   DirectFB ............................... no
   EGLFS .................................. yes
   EGLFS details:
    EGLFS OpenWFD ........................ no 
    EGLFS i.Mx6 .......................... no
    EGLFS i.Mx6 Wayland .................. no
    EGLFS RCAR ........................... no
    EGLFS EGLDevice ...................... yes 
    EGLFS GBM ............................ yes
    EGLFS Mali ........................... no 
    EGLFS Raspberry Pi ................... no 
    EGL on X11 ........................... no 
    LinuxFB ................................ no 
    VNC .................................... yes
    Mir client ............................. no

I guess that the EGLFS i.Mx6 is best suited and efficient for IMX6Q - but is it true ? - and especially how is it possible to activate this option instead of the current EGLDevice or GBM ?

I have configured Qt with -device linux-imx6-g++ ( using buildroot Custom configuration options) but it does not change anything and i don't see any other options so far.

Thanks for any help.

Hi gregoryciapa,

Don´t know how this going to be in build root, but in yocto you select the mx6 if you build enviroment and compiled with arm cortex a9, please check it:
