Hi all... I just upgraded to laatest kernel in experimental from 4.19.40 , and for my OpenCL app this now fails with this msg: amdgpu_device_initialize: DRM version is 2.50.0 but this driver is only compatible with 3.x.x. Booting back to 4.19.40 makes it work again. I have added a few files from amdgpu-pro package, to make openCL work here in centos7; but something must have changed in this new kernel for amdgpu support. As kernel 4.19.40 works fine, it is not a big issue here - just wanted to report it. Allan.
