I am building a system using buildroot on kernel 4.19.94-ti-r44. I am able to load the pvr kernel module and the user space driver with successful output in dmesg. I am trying to use Weston the drm-backend but it is failing with the following output:

I've tried using Weston 2.0 with the TI patches applies as well as Weston 5.0 using the patches from the arago meta yocto layer. Both version produce the same output.
It looks like the TI libgbm backend.c is still hardcoded to look for /usr/lib/gbm/gbm_pvr.so. Version 1.14 of the DDK symlinked this file to libpvrGBMWSEGL.so, but this library is not packaged in the 1.17 DDK. Should libgbm be pointed to another .so?
