How to get Weston running on Solidruns Hummingboard2 / GC2000

[Torsten Sievers]

Hi,

some update from my side.

I updated the device now to mesa-git
(revision 2412c4c81ea0488df865817a0de91ec46e359b72), wayland-protocols-1.9,
wayland-1.13.91 and weston 2.99.91
The problem still persists.

However i noticed in dmesg sporadic lines. I am uncertain if they are
related to the problem.

The dmesg line is       alloc_contig_range: [4e087, 4e088) PFNs busy

The message is always showing the same address.
When running weston-simple-egl the messages comes in a pack of 1-6 messages
within half a second and then the next pack comes in about 1-5 seconds
later. As soon as I stop weston-simple-egl the message disappears.
when running weston-simple-shm  the same message comes in as well, but only
1-2 messages per second, with 1-2 seconds gaps. In contrast to
weston-simple-egl the display of weston-simple-shm looks good.

Further glmark2 with drm-glesv2 backend is running visually fine on almost
all tests (only exception i noticed was terrain, where it is complaining
about shaders).

any clue where i should dig in to understand why the weston-simple-egl is
distorted?

Best regards
  Torsten
