That won't work. The kernel IOCTL structures have a size attached to
them, but the libdrm interface doesn't have that.
It clearly was a bad idea to munch in an extra layer of abstraction
here. I would say we should just deprecate that interface sooner or later.
Please use the following code in the UMD to query the info directly from
the kernel:
struct drm_amdgpu_info_device dev_info;
r = amdgpu_query_info(dev, AMDGPU_INFO_DEV_INFO, sizeof(dev_info),
&dev_info);
This way you also only need to make the two line change
include/drm/amdgpu_drm.h.

Christian.
