Hello, 
Recently, i am working on enabling mali 450 gpu at debian xorg X windows for hikey board which is one of 96boards.

I first implement xf86-video-armsoc(ver1.1.0) video driver, compile and cp armsoc_drv.so to directory "/usr/lib/xorg/modules/drivers".
And then compile arm mali r5p0 DDK and cp egl and gles libs(libEGL.so  libEGL.so.1  libEGL.so.1.4  libGLESv1_CM.so  libGLESv1_CM.so.1  libGLESv1_CM.so.1.1  libGLESv2.so  libGLESv2.so.2  libGLESv2.so.2.0  libMali.so) to directory "/usr/lib/aarch64-linux-gnu/" or "/usr/lib".

my xorg.conf is show as bellow:
----------------------------xorg.conf  start--------------------------
cat /etc/X11/xorg.conf
Section "Device"
        Identifier  "Card0"
        Driver      "armsoc"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        DefaultDepth 24
EndSection
----------------------------xorg.conf  end--------------------------
Then i run  startx, i can see the desktop on the monitor. 
But i found that the X process doesn't load any EGL and GLES libs by seeing the info of /proc/X process ID/task/*/smaps file.
And even when i run #es2_info , i get bellow error:

What's wrong? 
Am I missing something on integrating xf86-video-armsoc? 
And why X doesn't load any EGL and GLES so libs?
I paste the Xorg.0.log  at the end. 
Please tell me if you know what's going wrong, thanks.

Best regards,
-Xinliang Liu
