Hi
I'm trying to build and run latest OE master for a AM62 based machine
All builds fine.
I don't have the GPU working at runtime while the GPU works fine
using the 'same' configuration with kirkstone branches.
Apart from the GPU I did not (yet) see any regression as compared
with kirkstone. Note that the kernel is based on
ti-linux-6.1.y, 09.00.00.008.
First issue found is the shared objects in ti-img-rogue-umlibs are not
versioned shared objects, but the *.so files are packaged into the
ti-img-rogue-umlibs-dev package and thus not installed by default:
In that state OpenGL falls back to software rendering which works,
albeit slowly.
```
$ glmark2-es2-wayland
LoadLib: Couldn't load libpvr_dri_support.so: libpvr_dri_support.so: cannot
open shared object file: No such file or directory
libEGL warning: egl: failed to create dri2 screen
warning: queue 0xaaab104ebc90 destroyed while proxies still attached:

Creating the symlinks makes the dynamic linker happy, however then
OpenGL refuses to work at all:
```
$ cd /usr/lib
$ ln -s libpvr_dri_support.so.23.1.6404501 libpvr_dri_support.so
$ ln -s libsrv_um.so.23.1.6404501 libsrv_um.so

```
Is this supposed to work in current master?
Did anyone see that working?
Any hints on a way forward?
Thanks for any input.

Max
