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:

Bus error

---------------------------es2_info log end--------------------------

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
