Hello,
I'm trying to update from the kernel 4.17.17 to 5.3 on a Utilite pro
(GC2000) but I'm running a bit into trouble:
When on 4.17.17 I can run X11 with the armada driver and I get proper
OpenGL, with 5.3, the same user space, and the same kernel config
querying the chip specs via
drmCommandWriteRead(conn->fd, DRM_ETNAVIV_GET_PARAM,
&req, sizeof(req)))
fails, and consequently no HW acceleration is available and only
llvmpipe is used.
Similarly, when I try to run weston it works on 4.17.17 with
weston -B drm-backend.so --drm-device=card1
but with kernel 5.3 I get a message
"DRM device 'card1' is not a KMS device
and initializations failes. Trying card0 also fails, it tries to fall
back to llvmpipe and then things fail because of a llvmpipe bug with
"Coroutines Splitting" missing.
Anyway, before I have to start to bisect the kernel, I'd like to ask
whether someone has an idea what could go wrong there?
many thanks in advance
Gert
