Hi Weihang,
The simplest way is to replace the check of "drm.h" with "amdgpu_drm.h". This is
reasonable since dma-buf based MR won't work with old kernel anyway.
Alternatively, we can add a check for "amdgpu_drm.h" in CMakeLists.txt and add
some #ifdef's to dmabuf_alloc.c around the code related to amdgpu.
