how to compile xilinx_drm_dri.so to use in ubuntu aarch64

Hi,

I'm facing issues running graphical applications on ubuntu(16.04) booted on zynq.

For a lot of graphical applications include gdm, vlc, etc. all complains similar issue, something like:

 

libGL error: unable to load driver: xilinx_drm_dri.so 
libGL error: driver pointer missing 
libGL error: failed to load driver: xilinx_drm

Seems a lot of users are facing this problem, for example:

814006   ,  785664 ,  769985 .

Many don't have a solution or just have worked around by some specific way.

In fact, I compiled the linux kernel (4.9, 2017.3 ) to start the ubuntu desktop provided by non-xilinx vendor. the graphic issue took a lot of time, without any progress.

Some advice would be very helpful.

 

 

Regards,
Kang

Re: how to compile xilinx_drm_dri.so to use in ubuntu aarch64

When we run Soft_glmark2 demo from Wiki Ubuntu Desktop on ZCU102. we can see libGL error(3D model is displayed).
We reproduced the issue at our end and our observations are given below.
1. Soft_glmark2 demo always runs as expected.
2. When demo is running successfully, libGL errors appear on console. These errors can be ignored as they don’t stop demo from running. Most of the forums also suggest the same. For ex : https://forum.odroid.com/viewtopic.php?f=95&t=13424
3. This an application(soft_glmark2) crash. Since this application is fetched from Open source we may not be able to fix this crash.
